did i just learn something big?

Prerecorded music has ABSOLUTELY NO
SURVIVAL reward. Zero. It does not help
with procreation (well, unless you're the
one making the music, then you get
endless sex) and it does not help with
individual survival.
As such, one must seriously self test
(n=1) prerecorded music actually holds
you back.
If you're reading this and you try no
music for 2 weeks and fail, hit me up. I
have some mind blowing stuff to show
you in how you can control others with
music.

[1709.01149] Biotechnology and the lifetime of technical civilizations
The number of people able to end Earth's technical civilization has heretofore been small. Emerging dual-use technologies, such as biotechnology, may give similar power to thousands or millions of individuals. To quantitatively investigate the ramifications of such a marked shift on the survival of both terrestrial and extraterrestrial technical civilizations, this paper presents a two-parameter model for civilizational lifespans, i.e. the quantity L in Drake's equation for the number of communicating extraterrestrial civilizations. One parameter characterizes the population lethality of a civilization's biotechnology and the other characterizes the civilization's psychosociology. L is demonstrated to be less than the inverse of the product of these two parameters. Using empiric data from Pubmed to inform the biotechnology parameter, the model predicts human civilization's median survival time as decades to centuries, even with optimistic psychosociological parameter values, thereby positioning biotechnology as a proximate threat to human civilization. For an ensemble of civilizations having some median calculated survival time, the model predicts that, after 80 times that duration, only one in 1024 civilizations will survive -- a tempo and degree of winnowing compatible with Hanson's "Great Filter." Thus, assuming that civilizations universally develop advanced biotechnology, before they become vigorous interstellar colonizers, the model provides a resolution to the Fermi paradox.

Plastic fibres found in tap water around the world, study reveals | Environment | The Guardian
Scores of tap water samples from more than a dozen nations were analysed by scientists for an investigation by Orb Media, who shared the findings with the Guardian. Overall, 83% of the samples were contaminated with plastic fibres.

We are living on a plastic planet. What does it mean for our health?
New studies reveal that tiny plastic fibres are everywhere, not just in our oceans but on land too. Now we urgently need to find out how they enter our food, air and tap water and what the effects are on all of us

The US had the highest contamination rate, at 94%, with plastic fibres found in tap water sampled at sites including Congress buildings, the US Environmental Protection Agency’s headquarters, and Trump Tower in New York. Lebanon and India had the next highest rates.

...

Current standard water treatment systems do not filter out all of the microplastics, Mahon said: “There is nowhere really where you can say these are being trapped 100%. In terms of fibres, the diameter is 10 microns across and it would be very unusual to find that level of filtration in our drinking water systems.”

Bottled water may not provide a microplastic-free alternative to tapwater, as the they were also found in a few samples of commercial bottled water tested in the US for Orb.

The Flynn effect for verbal and visuospatial short-term and working memory: A cross-temporal meta-analysis
Specifically, the Flynn effect was found for forward digit span (r = 0.12, p < 0.01) and forward Corsi block span (r = 0.10, p < 0.01). Moreover, an anti-Flynn effect was found for backward digit span (r = − 0.06, p < 0.01) and for backward Corsi block span (r = − 0.17, p < 0.01). Overall, the results support co-occurrence theories that predict simultaneous secular gains in specialized abilities and declines in g. The causes of the differential trajectories are further discussed.

The Rise and Fall of Cognitive Control - Behavioral Scientist
The results highlight the downsides of controlled processing. Within a population, controlled processing may—rather than ensuring undeterred progress—usher in short-sighted, irrational, and detrimental behavior, ultimately leading to population collapse. This is because the innovations produced by controlled processing benefit everyone, even those who do not act with control. Thus, by making non-controlled agents better off, these innovations erode the initial advantage of controlled behavior. This results in the demise of control and the rise of lack-of-control. In turn, this eventually leads to a return to poor decision making and the breakdown of the welfare-enhancing innovations, possibly accelerated and exacerbated by the presence of the enabling technologies themselves. Our models therefore help to explain societal cycles whereby periods of rationality and forethought are followed by plunges back into irrationality and short-sightedness.

https://static1.squarespace.com/static/51ed234ae4b0867e2385d879/t/595fac998419c208a6d99796/1499442499093/Cyclical-Population-Dynamics.pdf
Psychologists, neuroscientists, and economists often conceptualize decisions as arising from processes that lie along a continuum from automatic (i.e., “hardwired” or overlearned, but relatively inflexible) to controlled (less efficient and effortful, but more flexible). Control is central to human cognition, and plays a key role in our ability to modify the world to suit our needs. Given its advantages, reliance on controlled processing may seem predestined to increase within the population over time. Here, we examine whether this is so by introducing an evolutionary game theoretic model of agents that vary in their use of automatic versus controlled processes, and in which cognitive processing modifies the environment in which the agents interact. We find that, under a wide range of parameters and model assumptions, cycles emerge in which the prevalence of each type of processing in the population oscillates between 2 extremes. Rather than inexorably increasing, the emergence of control often creates conditions that lead to its own demise by allowing automaticity to also flourish, thereby undermining the progress made by the initial emergence of controlled processing. We speculate that this observation may have relevance for understanding similar cycles across human history, and may lend insight into some of the circumstances and challenges currently faced by our species.

Dadly adaptations | West Hunter
If we understood how this works, we might find that individuals and populations vary in their propensity to show paternal care ( for genetic reasons). I would guess that paternal care was ancestral in modern humans, but it’s easy enough to lose something like this when selective pressures no longer favor it. Wolves have paternal care, but dogs have lost it.

This could have something to do with better health in married men. High testosterone levels aren’t cost-free.

It’s possible that various modern environmental factors interfere with the triggers for dadliness. That would hardly be surprising, since we don’t really know how they work.

All this has a number of interesting social implications. Let’s see how many of them you guys can spot.

Poles in the Tent: https://westhunt.wordpress.com/2013/07/09/poles-in-the-tent/
I’m considering a different question: what was the impact of men’s contribution on their children’s survival and fitness? That’s not quite the same as the number of calories contributed. Food is not a single undifferentiated quantity: it’s a category, including a number of different kinds that can’t be freely substituted for each other. Proteins, fats, and carbohydrates can all serve as fuel, but you need protein to build tissue. And amino acids, the building blocks of proteins, are not all fungible. Some we can’t synthesize (essential amino acids) others can only be synthesized from a limited set of precursors, etc. Edible plants often have suboptimal mixes of amino acids ( too many Qs, not enough Us) , but I’ve never heard of this being a problem with meat. Then you have to consider essential fatty acids, vitamins, and trace elements.

In principle, if high-quality protein were the long pole in the tent, male provisioning of meat, which we see in chimpanzees, might matter quite a bit more than you would think from the number of calories alone. I’m not say that is necessarily the case, but it might be, and it’s worth checking out.

Sexual selection vs job specialization: https://westhunt.wordpress.com/2017/10/02/sexual-selection-vs-job-specialization/
Pretty much every species is subject to sexual selection: heritable characteristics that lead to more mates or better mates can be favored by natural selection. Typically, sexual selection favors different strategies in males and females. Generally, males can gain fitness with increased mating opportunities, while females gain more from high-quality mates or mates that confer resources. Since the variance in reproduction is usually greater in males than females, sexual selection is usually stronger in males, although it exists and is significant in both sexes.

Usually, though, males and females of a given species have very similar ways of making a living. A male deer and a female deer both eat grass or arugula or whatever. Sexual selection may drive them to evolve in different directions, but finding something to eat mostly drives them in the same direction.

Humans are an exception. In the long past, men hunted and women gathered. The mix varied: in Arctic regions, men produce almost all the food (while women made and repaired gear, as well as raising children). In groups like the Bushmen, women produced most of the calories, but done rightly you would count more than calories: if most of the local plants had low protein or low-quality protein (wrong amino acid mix), meat from hunting could be important out of proportion to its caloric value.

This has been going for a long time, so there must have been selection for traits that aided provisioning ability in each sex. Those job-related selective pressures probably changed with time. For example, male strength may have become less valuable when the Bushmen developed poison arrows.

I was looking for an intelligent discussion of this question – but I ran into this and couldn’t force myself to read further: ” It should not simply be assumed that the exclusion of women from hunting rests upon “natural” physiological differences. ”

God give me strength.

What does Greg think about the “plows vs hoes” theory? (As seen here, although Sarah Constantin didn’t invent it.)

The claim is that some societies adopted farming (Europe, the Middle East, Asia) while some societies adopted horticulture (Oceana, sub-Saharan Africa, various primitive peoples) and that this had an affect on gender relations.

Basically: farming is backbreaking work, which favours males, giving them a lot of social capital. You end up with a patriarchal kind of society, where the men do stuff and the women are mostly valuable for raising offspring.

...

It’s kinda true, in places. There is a connection I haven’t seen explicated: the ‘hoe culture” has to have some factor keeping population density low, so that labor is scarcer than land. Tropical diseases like malaria might be part of that. Then again, crops like yams don’t store well, better to keep them in the ground until eating. That means it’s hard to tax people – easy with grain bins. No taxes -> no State – > high local violence. At times, VD may also help limit density, cf Africa’s ‘sterility belt’.

I am not a Moron: https://westhunt.wordpress.com/2017/11/03/i-am-not-a-moron/
So said Augustin Fuentes on Twitter, a few days ago. He’s the same guy that said “Genes don’t do anything by themselves; epigenetics and complex metabolic and developmental systems are at play in how bodies work. The roundworm C. elegans has about 20,000 genes while humans have about 23,000 genes, yet it is pretty obvious that humans are more than 15-percent more complex than roundworms. So while genes matter, they are only a small part of the whole evolutionary picture. Focusing just on DNA won’t get you anywhere.”

Fuentes was claiming that we don’t really know that, back in prehistory, men did most of the hunting while women gathered.

...

Someone (Will@Evolving _Moloch) criticized this as a good candidate for the most misleading paragraph ever written. The folly of youth! When you’ve been around as long as I have, sonny, you will realize how hard it is to set records for stupidity.

Fuente’s para is multidimensional crap, of course. People used to hunt animals like red deer, or bison, or eland: sometimes mammoths or rhinos. Big animals. Back in the day, our ancestors used stabbing spears, which go back at least half a million years. Stand-off weapons like atlatls, or bows, or JSOW, are relatively recent. Hunters took big risks & suffered frequent injuries. Men are almost twice as strong as women, particularly in upper-body strength, which is what matters in spear-chucking. They’re also faster, which can be very important which your ambush fails.
So men did the hunting. This isn’t complicated.

Which contemporary hunter-gather societies followed this pattern, had men do almost all of the big-game hunting? All of them.

...

Look, feminists aren’t happy with human nature, the one that actually exists and is the product of long-term evolutionary pressures. Too bad for them. When they say stuff like “It should not simply be assumed that the exclusion of women from hunting rests upon “natural” physiological differences. “, they just sound like fools.. ‘natural physiological differences” exist. They’re as obvious a punch in the kisser.

Suppose you wanted to construct a society with effective sexual equality – which is probably just a mistake, but suppose it. The most effective approach would surely entail knowing and taking into account how the world actually ticks. You’d be better off understanding that about 6,000 genes (out of 20,000) show significant expression differences between the sexes, than by pretending that we’re all the same. You would to make it so: by hook or by crook, by state force and genetic engineering.

Similarly, if you want to minimize war, pretending that people aren’t warlike is a poor start – about as sensible as fighting forest fires by pretending that trees aren’t flammable.

My advice to Augustin Fuentes, about not being a moron: show, don’t tell.

https://westhunt.wordpress.com/2017/11/03/i-am-not-a-moron/#comment-97721
Since DNA is the enduring part, the part that gets transmitted from one generation to the next, the part that contains the instructions/program that determine development and specify everything – he’s wrong. Stupid, like you. Well, to be fair, ignorant as well: there are technical aspects of genetics that Agustin Fuentes is unlikely to know anything about, things that are almost never covered in the typical education of an anthropologist. I doubt if he knows what a Fisher wave is, or anything about selfish genetic elements, or coalescent theory, or for that matter the breeder’s equation.

There are a number of complex technical subjects, things that at least some people understand: those people can do stuff that the man in the street can’t. In most cases, amateurs don’t jump in and pretend to know what’s going on. For example you don’t hear much concerning amateur opinions concerning detonation physics or group theory. But they’re happy to have opinions about natural selection, even though they know fuck-all about it.

The Genomic Health Of Ancient Hominins | bioRxiv
On a broad scale, hereditary disease risks are similar for ancient hominins and modern-day humans, and the GRS percentiles of ancient individuals span the full range of what is observed in present day individuals. In addition, there is evidence that ancient pastoralists may have had healthier genomes than hunter-gatherers and agriculturalists. We also observed a temporal trend whereby genomes from the recent past are more likely to be healthier than genomes from the deep past.

Gwern has interesting take (abstract is misleading): https://twitter.com/gwern/status/871061144152178688

here it is in conclusion (and cf Figure 3A):
The genomic health of ancient individuals appears to have improved over time (Figure 3B). This calls into question the idea that genetic load has been increasing in human populations (Lynch 2016). However, there exists a perplexing pattern: ancient individuals who lived within the last few thousand years have healthier genomes, on average, than present day humans.

After controlling for age, BMI, and other variables, knee OA prevalence was 2.1-fold higher (95% confidence interval, 1.5–3.1) in the postindustrial sample than in the early industrial sample. Our results indicate that increases in longevity and BMI are insufficient to explain the approximate doubling of knee OA prevalence that has occurred in the United States since the mid-20th century. Knee OA is thus more preventable than is commonly assumed, but prevention will require research on additional independent risk factors that either arose or have become amplified in the postindustrial era.

Tucker Carlson: "Men Seem To Be Becoming Less Male": https://www.realclearpolitics.com/video/2018/03/08/tucker_carlson_men_seem_to_be_becoming_less_male.html
Carlson interviewed Dr. Jordan Peterson who blamed the "insidious" movement being driven by the "radical left" that teaches there a problem of "toxic masculinity." He said ideological policies focus on "de-emphasizing masculinity may be part of the problem."

...

Those are the numbers. They paint a very clear picture: American men are failing, in body, mind and spirit. This is a crisis. Yet our leaders pretend it’s not happening. They tell us the opposite is true: Women are victims, men are oppressors. To question that assumption is to risk punishment. Even as women far outpace men in higher education, virtually every college campus supports a women’s studies department, whose core goal is to attack male power. Our politicians and business leaders internalize and amplify that message. Men are privileged. Women are oppressed. Hire and promote and reward accordingly.

https://pinboard.in/u:nhaliday/b:bd7b0a50d741
But it also hints at an almost opposite take: average testosterone levels have been falling for decades, so at this point these businessmen would be the only “normal” (by 1950s standards) men out there, and everyone else would be unprecedently risk-averse and boring.

This Is How Much of Autism Is Genetic: http://time.com/4956316/how-much-of-autism-is-genetic/
Indeed, when Sandin tracked autism diagnoses over time among the sibling pairs, he found that genetics likely accounts for around 83% of the disorder. That compares to nearly 90% reported in previous studies of twins only. Using the new model, environmental factors probably contribute around 17% to the risk of developing autism.

Fertility trends by social status
The study reveals that as fertility declines, there is a general shift from a positive to a negative or neutral status-fertility relation. Those with high income/wealth or high occupation/social class switch from having relatively many to fewer or the same number of children as others. Education, however, depresses fertility for as long as this relation is observed (from early in the 20th century).

This article discusses how fertility relates to social status with the use of a new dataset, several times larger than the ones used so far. The status-fertility relation is investigated over several centuries, across world regions and by the type of status-measure. The study reveals that as fertility declines, there is a general shift from a positive to a negative or neutral status-fertility relation. Those with high income/wealth or high occupation/social class switch from having relatively many to fewer or the same number of children as others. Education, however, depresses fertility for as long as this relation is observed (from early in the 20th century).

Is America smart enough? A Q&A with Garett Jones on IQ and the 'Hive Mind' - AEI | Pethokoukis Blog » AEIdeas
hmmm, shit:
Well, if we’re looking at the very recent trends over the last couple of decades, there is not much evidence that there’s been a bigger return to IQ than there used to be. I think there’s moderate evidence that there’s actually an increase in return to personality-type skills.

evidence: https://pinboard.in/u:nhaliday/b:d70bdc68a51c

One of my colleagues one said offhand a line that I think others have said, which is that 90% of success is staying off the Internet. And I think there’s something to this idea that the return to personality-type measures is probably a lot higher than it used to be. Agreeableness, conscientiousness, especially in certain settings. I’ve looked at the normal statistical results and they don’t find an increase in return to IQ in recent decades. But there’s a couple of studies out there that do find an increase in returns to what they call non-cognitive skills.

I think personality might be mattering more. If the robots are going to take some jobs, they’ll probably be taking a lot of brainy type jobs. But they’re going to be a little behind the times when it comes to personality. And a lot of in-person services are going to depend on personality traits.

more:
So Google and its many spinoffs replace a lot of the need for crystallized intelligence. But the need for fluid intelligence is going to be with us for quite some time. The ability to look at a new, novel situation and figure out what’s going on here.

Some pro-IQ supporters, especially on the Internet, tend to think that there’s this some kind of cutoff where above a certain level IQ matters a lot. Below it, it doesn’t matter very much. And I just don’t find evidence of that. I think that there’s a reason why the market pays for IQ, for higher IQ across the range of the scores. It’s because it’s always good to have somebody around who can just look at an ambiguous situation and figure out what’s going on.

another neat comment:
I think the obsession with years of education really needs to end. And there should be an obsession with broad based test scores. If people don’t want to use IQ scores, that’s fine. But they should at least be looking at broad based test scores, things like the NAEPs, other test scores that the US government is quite happy to report on the Department of Education’s website. These should be the measures we look at. We should be looking a lot less at years of education.

Summary | EWG's 2017 Shopper's Guide to Pesticides in Produce
https://www.hsph.harvard.edu/news/features/health-benefits-organic-food-farming-report/
Three long-term birth cohort studies in the U.S. suggest that pesticides are harming children’s brains. In these studies, researchers found that women’s exposure to pesticides during pregnancy, measured through urine samples, was associated with negative impacts on their children’s IQ and neurobehavioral development, as well as with ADHD [attention deficit hyperactivity disorder] diagnoses. Also, one of the studies looked at structural brain growth using magnetic resonance imaging and found that the gray matter was thinner in children the higher their mothers’ exposure to organophosphates, which are used widely in pesticides. I think that’s quite scary.

The Relation of Toxoplasma Infection and Sexual Attraction to Fear, Danger, Pain, and Submissiveness - Jul 28, 2016
A cross-sectional cohort study performed on 36,564 subjects (5,087 Toxoplasma free and 741 Toxoplasma infected) showed that infected and noninfected subjects differ in their sexual behavior, fantasies, and preferences when age, health, and the size of the place where they spent childhood were controlled (F(24, 3719) = 2.800, p < .0001). In agreement with our a priori hypothesis, infected subjects are more often aroused by their own fear, danger, and sexual submission although they practice more conventional sexual activities than Toxoplasma-free subjects. We suggest that the later changes can be related to a decrease in the personality trait of novelty seeking in infected subjects, which is potentially a side effect of increased concentration of dopamine in their brain.

Sustainability | West Hunter
There have been societies that functioned for a long time, thousands of years. They had sustainable demographic patterns. That means that they had enough children to replace themselves – not necessarily in every generation, but over the long haul. But sustainability requires more than that. Long-lived civilizations [ones with cities, literacy, governments, and all that] had a pattern of natural selection that didn’t drastically decrease intelligence – in some cases, one that favored it, at least in some subgroups. There was also ongoing selection against mutational accumulation – which meant that individuals with more genetic load than than average were significantly less likely to survive and reproduce. Basically, this happened through high child mortality, and in some cases by lower fitness in lower socioeconomic classes [starvation]. There was nothing fun about it.

Modern industrialized societies are failing on all three counts. Every population that can make a decent cuckoo clock has below-replacement fertility. The demographic pattern also selects against intelligence, something like one IQ point a generation. And, even if people at every level of intelligence had the same number of children, so that there was no selection against IQ, we would still be getting more and messed up, because there’s not enough selection going on to counter ongoing mutations.

It is possible that some country, or countries, will change in a way that avoids civilizational collapse. I doubt if this will happen by voluntary action. Some sort of technological solution might also arise – but it has to be soon.

Again, I don’t believe a word of it. As for the declining rate of innovation, you have to have a really wide-ranging understanding of modern science and technology to have any feeling for what the underlying causes are. I come closer than most, and I probably don’t know enough. You don’t know enough. Let me tell you one thing: if genetic potential IQ for IQ had dropped 1 std, we’d see the end of progress in higher mathematics, and that has not happened at all.

Moreover, the selective trends disfavoring IQ all involve higher education among women and apparently nothing else – a trend which didn’t really get started until much more recently.

Not long enough, nor is dysgenic selection strong enough.

About 40% of those Americans with credit cards keep a balance on their credit cards and pay ridiculous high interest. But that must be the right decision!
https://westhunt.wordpress.com/2013/05/09/sustainability/#comment-13499
” then that is their decision” – that’s fucking obvious. The question is whether they tend to make decisions that work very well – saying ‘that is their decision” is exactly the kind of crap I was referring to. As for “they probably have it coming” – if I’m smarter than you, which I surely am, using those smarts to rook you in every possible way must be just peachy. In fact, I’ll bet I could manage it even after warning you in advance.

On average, families in this country have paid between 10% and 14% of their income in debt service over the past few decades. That fraction averages considerably higher in low-income families – more like 18%. A quarter of those low income families are putting over 40% of their income into debt service. That’s mostly stuff other than credit-card debt.

Is this Straussian?

It's Beyond My Control: A Cross-Temporal Meta-Analysis of Increasing Externality in Locus of Control, 1960-2002 - Dec 21, 2016
Two meta-analyses found that young Americans increasingly believe their lives are controlled by outside forces rather than their own efforts. Locus of control scores became substantially more external (about .80 standard deviations) in college student and child samples between 1960 and 2002. The average college student in 2002 had a more external locus of control than 80% of college students in the early 1960s. Birth cohort/time period explains 14% of the variance in locus of control scores. The data included 97 samples of college students (n = 18,310) and 41 samples of children ages 9 to 14 (n = 6,554) gathered from dissertation research. The results are consistent with an alienation model positing increases in cynicism, individualism, and the self-serving bias. The implications are almost uniformly negative, as externality is correlated with poor school achievement, helplessness, ineffective stress management, decreased self-control, and depression.

One may of course be skeptical that this general trend will also apply to the growth of our technology and economy at large, as innovation seems to continually postpone our clash with the ceiling, yet it seems inescapable that it must. For in light of what we know about physics, we can conclude that exponential growth of the kinds we see today, in technology in particular and in our economy more generally, must come to an end, and do so relatively soon.

A Resolution of the Mutation Load Paradox in Humans
It has been argued that the mutation load, the proportional reduction in population mean fitness relative to the fitness of an idealized mutation-free individual, allows a theoretical prediction of the proportion of individuals in the population that fail to reproduce as a consequence of these harmful mutations. Application of this theory to humans implies that at least 88% of individuals should fail to reproduce and that each female would need to have more than 16 offspring to maintain population size. This prediction is clearly at odds with the low reproductive excess of human populations. Here, we derive expressions for the fraction of individuals that fail to reproduce as a consequence of recurrent deleterious mutation (φ) for a model in which selection occurs via differences in relative fitness, such as would occur through competition between individuals. We show that φ is much smaller than the value predicted by comparing fitness to that of a mutation-free genotype. Under the relative fitness model, we show that φ depends jointly on U and the selective effects of new deleterious mutations and that a species could tolerate 10’s or even 100’s of new deleterious mutations per genome each generation.

Social Epistasis Amplifies the Fitness Costs of Deleterious Mutations, Engendering Rapid Fitness Decline Among Modernized Populations | SpringerLink
- Michael A. Woodley

We argue that in social species, interorganismal gene-gene interactions, which in previous literatures have been termed social epistasis, allow genomes carrying deleterious mutations to reduce via group-level pleiotropy the fitness of others, including noncarriers. This fitness reduction occurs by way of degradation of group-level processes that optimize the reproductive ecology of a population for intergroup competition through, among other mechanisms, suppression of free-riding.

--

Fitness indicators theory (Houle 2000; Miller 2000) predicts that the behavioral and physiological condition of prospective partners strongly influences female mate choice in particular, as these constitute honest indicators of underlying genetic quality. Furthermore, as deleterious mutations are pleiotropic (i.e., they can influence the development of multiple traits simultaneously), they are a source of genetic correlation among diverse behavioral and physiological domains, yielding a latent general fitness factor( f ). This optimizes the efficiency of sexual selection, as selection for quality with respect to one domain will increase the probability of selection for quality “across the board” (Houle 2000; Miller 2000). If purifying selection is primarily cryptic—working by virtue of those lower in f simply being less successful in competition for mates and therefore producing fewer offspring relative to those higher in the factor—then considerably less reproductive failure is needed to solve the mutation load paradox (19% instead of 88% based on simulations in Leseque et al. 2012).

...

Theoretical work involving humans suggests a loss of intrinsic fitness of around 1% per generation in the populations of modernized countries (Lynch 2016; Muller 1950). Thus, these might yet be undergoing mutational meltdown, albeit very gradually (i.e., over the course of centuries)

...

An interesting observation is that the fitness of the populations of modernized nations does appear to be rapidly decreasing—although not in a manner consonant with the direct action of deleterious mutations on the fitness of individuals (as per the mutation load paradox).

...

Increased education has furthermore encouraged individuals to trade fertility against opportunities to enhance their social status and earning power, with the largest fitness losses occurring among those with high status who potentially carry fewer deleterious mutations (i.e., by virtue of possessing higher levels of traits that exhibit some sensitivity to mutation load, such as general intelligence; Spain et al. 2015; Woodley of Menie et al. 2016a). Hitherto not considered is the possibility that the demographic transition represents a potential change in the fitness characteristics of the group-level extended phenotype of modernized populations, indicating that there might exist pathways through which deleterious mutations that accumulate due to ecological mildness could pathologically alter fertility tradeoffs in ways that might account for the maladaptive aspects of the fertility transition (e.g., subreplacement fertility; Basten, Lutz and Scherbov, 2013).

...

Cooperation, though offering significant fitness benefits to individual organisms and groups, involves some costs for cooperators in order to realize mutual gains for all parties. Free riders are individuals that benefit from cooperation without suffering any of the costs needed to sustain it. Hence, free riders enjoy a fitness advantage relative to cooperators via the former’s parasitism on the latter.

...

The balance of selection can alternate between the different levels depending on the sorts of selective challenges that a population encounters. For example, group selection may operate on human populations during times of intergroup conflict (i.e., warfare), whereas during times of peace, selection may tend to favor the fitness of individuals instead (Woodley and Figueredo 2013; Wilson 2002). A major factor that seems to permit group-level selection to be viable under certain ecological regimes is the existence of free-rider controls, i.e., features of the group’s social ecology that curb the reproductive fitness of the carriers of “selfish” genetic variants (MacDonald 1994; Wilson 2002).

...

High-status individuals participate in the generation and vertical cultural transmission of free-rider controls—these take the form of religious and ideological systems which make a virtue out of behaviors that overtly benefit the group, and a vice out of those that only favor individual-level fitness, via the promotion of ethnocentrism, martyrdom, and displays of commitment (MacDonald 1994, 2009, 2010; Wilson 2002). Humans are furthermore equipped with specialized mental adaptations for coordinating as part of a group, such as effortful control—the ability to override implicit behavioral drives via the use of explicit processing systems, which allow them to regulate their behavior based on what is optimal for the group (MacDonald 2008). The interaction between individuals of different degrees of status, i.e., those that generate and maintain cultural norms and those who are merely subject to them, therefore constitutes a form of social epistasis, as the complex patterns of interactions among genomes that characterize human culture have the effect of regulating both individual- and group-level (via the curbing of free-riding) fitness (MacDonald 2009, 2010).

Mutations that push the behavior of high-status individuals away from the promotion of group-selected norms may promote a breakdown of or otherwise alter these social epistatic interactions, causing dysregulation of the group’s reproductive ecology. Behavioral changes are furthermore a highly likely consequence of mutation accumulation, as “behavior” (construed broadly) is a large potential target for new mutations (Miller 2000; Lynch 2016) 1 owing to the fact that approximately 84% of all genes in the human genome are involved in some aspect of brain development and/or maintenance (Hawrylycz et al. 2012).

Consistent with the theorized role of group-level (cultural) regulatory processes in the maintenance of fitness optima, positive correlations exist between religiosity (a major freerider control; MacDonald 1994; Wilson 2002) and fertility, both at the individual differences and cross-cultural levels (Meisenberg 2011). Religiosity has declined in modernized nations—a process that has gone hand-in-hand with the rise of a values system called postmaterialism (Inglehart 1977), which is characterized by the proliferation of individualistic, secular, and antihierarchical values (Welzel 2013). The holding of these values is negatively associated with fertility, both at the individual level (when measured as political liberalism; Goldstone et al. 2011) and across time and cultures (Inglehart and Appel 1989). The rise of postmaterialist values is also associated with increasingly delayed onset of reproduction (Klien 1990) which directly increases the (population) mutation load.

Pathological Altruism

Some of the values embodied in postmaterialism have been linked to the pathological altruism phenomenon, i.e., forms of altruism that damage the intended recipients or givers of largesse (Oakley et al. 2012; Oakley 2013). Virtues associated with altruism such as kindness, fidelity, magnanimity, and heroism, along with quasi-moral traits associated with personality and mental health, may be under sexual selection and might therefore be sensitive, through the f factor, to the deleterious effects of accumulating mutations (Miller 2007).

...

Another form of pathologically altruistic behavior that Oakley (2013) documents is self-righteousness, which may be increasing, consistent with secular trend data indicating elevated levels of self-regarding behavior among Western populations (sometimes called the narcissism epidemic; Twenge and Campbell 2009). This sort of behavior constitutes a key component of the clever silly phenomenon in which the embrace of counterfactual beliefs is used to leverage social status via virtue signaling (e.g., the conflation of moral equality among individuals, sexes, and populations with biological equality) (Dutton and van der Linden 2015; Charlton 2009; Woodley 2010). There may be a greater number of influential persons inclined to disseminate such beliefs, in that the prevalence of phenotypes disposed toward egoistic behaviors may have increased in Western populations (per Twenge and coworkers’ research), and because egoists, specifically Machiavellians and narcissists, appear advantaged in the acquisition of elite societal stations (Spurk et al. 2015).

[Do Bad Guys Get Ahead or Fall Behind? Relationships of the Dark Triad of Personality With Objective and Subjective Career Success: http://sci-hub.tw/http://journals.sagepub.com/doi/abs/10.1177/1948550615609735

After controlling for other relevant variables (i.e., gender, age, job tenure, organization size, education, and work hours), narcissism was positively related to salary, Machiavellianism was positively related to leadership position and career satisfaction, and psychopathy was negatively related to all analyzed outcomes.]

...

By altering cultural norms, elite egoists may encourage the efflorescence of selfish behaviors against which some older and once highly influential cultural systems acted. For example, Christianity in various forms strongly promoted personal sacrifice for the good of groups and proscribed egoistic behaviors (Rubin 2015), but has declined significantly in terms of cultural power following modernization (Inglehart 1977). Thus, it is possible that a feedback loop exists wherein deleterious mutation accumulation raises population levels of egoism, either directly or indirectly, via the breakdown of developmental constraints on personality canalization; the resultantly greater number of egoists are then able to exploit relevant personality traits to attain positions of sociocultural influence; and through these … [more]

Prevalence and architecture of de novo mutations in developmental disorders : Nature
We estimate that 42% of our cohort carry pathogenic DNMs in coding sequences; approximately half of these DNMs disrupt gene function and the remainder result in altered protein function. We estimate that developmental disorders caused by DNMs have an average prevalence of 1 in 213 to 1 in 448 births, depending on parental age. Given current global demographics, this equates to almost 400,000 children born per year.

Information Processing: Boom, Bust, and the Global Race for Scientific Talent
Falling Behind? is a recent (March 2014) book by Michael Teitelbaum of the Sloan Foundation, a demographer and long time critic of STEM (Science, Technology, Engineering and Mathematics) shortage claims. Falling Behind? is an excellent book with a wealth of data and information on the history of booms and busts in science and engineering employment since World War II, STEM shortage claims in general, and lobbying for “high-skilled” immigration “reform”. Although I have been a student of these issues for many years, I encountered many facts and insights that I did not know or had not thought of. Nonetheless the book has a number of weakenesses which readers should keep in mind.

... The evidence assembled in this book leads inescapably to three core findings:

o First, that the alarms about widespread shortages or shortfalls in the number of U.S. scientists and engineers are quite inconsistent with nearly all available evidence;

o Second, that similar claims of the past were politically successful but resulted in a series of booms and busts that did harm to the U.S. science and engineering enterprise and made careers in these fields increasingly unattractive; and

o Third, that the clear signs of malaise in the U.S. science and engineering workforce are structural in origin and cannot be cured simply by providing additional funding. To the contrary, recent efforts of this kind have proved to be destabilizing, and advocates should be careful what they wish for. ...

- “In the academic job market, there is no noticeable shortage in any discipline. In fact, there are signs of an oversupply of Ph.D.’s vying for tenure-track faculty positions in many disciplines (e.g., biomedical sciences, physical sciences).”
- “In the government and government-related job sector, certain STEM disciplines have a shortage of positions at the Ph.D. level (e.g., materials science engineering, nuclear engineering) and in general (e.g., systems engineers, cybersecurity, and intelligence professionals) due to the U.S. citizenship requirement. In contrast, an oversupply of biomedical engineers is seen at the Ph.D. level, and there are transient shortages of electrical engineers and mechanical engineers at advanced-degree levels.”
- “In the private sector, software developers, petroleum engineers, data scientists, and those in skilled trades are in high demand; there is an abundant supply of biomedical, chemistry, and physics Ph.D.’s; and transient shortages and surpluses of electrical engineers occur from time to time.”

I don’t think anyone is prepared for how far off of reality the Higher-Ed/STEM/High-Tech/Immigration story is. Even Bannon.

This is arguably the steepest pyramid scheme in the US & in the strategic sector that can least afford it. Yet it has ZERO to do with merit or xenophobia.
As such it is defended by a single mega lie of such size that no one can afford to rethink it. Myself included. It‘s a lie that has defined who we are for 50 years. I’m 53 and know nothing other than the lie. And the lie plays on the best parts of our American soul & narrative.
Work backwards. You‘ll see that perhaps the top 5-10 and not the top 100 universities should be training most all PhDs. Administrators should be fired. Tuition slashed. Strategic rivals barred from our labs. Diversity decreased or addressed *radically* earlier. Debt forgiven.
More students discouraged from four year college and into higher stability occupations. Massive salaries paid in fields that could restart growth. Transparency and accountability decreased for researcher and jacked up for administrations. Sports scholarships and legacies removed.
It’s so crazy what we need to do, that it‘s just easier to call anyone who dares rethink it an elitist or a xenophobe or an idiot or a pessimist or a nationalist. So I’m obviously going to be called all those things. As I was when I talked about mortgage backed securities in ‘02.

Bisphenol A (BPA)
Alternatives to BPA containers not easy for U.S. foodmakers to find: http://www.washingtonpost.com/wp-dyn/content/article/2010/02/22/AR2010022204830.html

Food is main source of BPA for consumers, thermal paper also potentially significant: https://www.efsa.europa.eu/en/press/news/130725
New data resulting from an EFSA call for data led to a considerable refinement of exposure estimates compared to 2006. For infants and toddlers (aged 6 months-3 years) average exposure from the diet is estimated to amount to 375 nanograms per kilogram of body weight per day (ng/kg bw/day) whereas for the population above 18 years of age (including women of child-bearing age) the figure is up to 132 ng/kg bw/day. By comparison, these estimates are less than 1% of the current Tolerable Daily Intake (TDI) for BPA (0.05 milligrams/kg bw/day) established by EFSA in 2006.

For all population groups above three years of age thermal paper was the second most important source of BPA after the diet (potentially accounting for up to 15% of total exposure in some population groups).

Among other key findings, scientists found dietary exposure to BPA to be the highest among children aged three to ten (explainable by their higher food consumption on a body weight basis). Canned food and non-canned meat and meat products were identified as major contributors to dietary BPA exposure for all age groups.

Selection against variants in the genome associated with educational attainment
first direct, genotypic, longitudinal evidence I think?
fulltext: https://www.dropbox.com/s/9vq5t6urtu930xe/2017-kong.pdf

Epidemiological and genetic association studies show that genetics play an important role in the attainment of education. Here, we investigate the effect of this genetic component on the reproductive history of 109,120 Icelanders and the consequent impact on the gene pool over time. We show that an educational attainment polygenic score, POLY_EDU, constructed from results of a recent study is associated with delayed reproduction (P < 10^−100) and fewer children overall. _The effect is stronger for women and remains highly significant after adjusting for educational attainment._ Based on 129,808 Icelanders born between 1910 and 1990, we find that the average POLY_EDU has been declining at a rate of ∼0.010 standard units per decade, which is substantial on an evolutionary timescale. Most importantly, because POLY_EDU only captures a fraction of the overall underlying genetic component the latter could be declining at a rate that is two to three times faster.

- POLY_EDU has negative effect on RS for men, while EDU itself (or just controlling for POLY_EDU?) has positive effect
- also has some trends for height (0) and schizophrenia (-)

The Marching Morons: https://westhunt.wordpress.com/2017/01/22/the-marching-morons/
There’s a new paper out on how the frequency of variants that affect educational achievement (which also affect IQ) have been changing over time in Iceland. Naturally, things are getting worse.

We don’t have all those variants identified yet, but from the fraction we do know and the rate of change, they estimate that genetic potential for IQ is dropping about 0.30 point per decade – 3 points per century, about a point a generation. In Iceland.

Sounds reasonable, in the same ballpark as demography-based estimates.

It would be interesting to look at moderately recent aDNA and see when this trend started – I doubt if has been going on very long. [ed.: I would guess since the demographic transition/industrial revolution, though, right?]

This is the most dangerous threat the human race faces.

Men’s status and reproductive success in 33 nonindustrial societies: Effects of subsistence, marriage system, and reproductive strategy
Status hierarchies have changed dramatically throughout human history, yet we find that the association between status and reproductive success does not depend on subsistence category (foraging, horticulture, pastoralism, agriculture) or how status is measured. These findings suggest no significant increase in selection on status-enhancing traits with the domestication of plants and animals.

We found a significant overall effect of status on RS (r = 0.19), though this effect was significantly lower than for nonhuman primates (r = 0.80).

The Predictive Validity of Ideal Partner Preferences: A Review and Meta-Analysis
[A] new meta-analysis spanning the attraction and relationships literatures (k=97) revealed that physical attractiveness predicted romantic evaluations with a moderate-to-strong effect size (r = ~.40) for both sexes, and earning prospects predicted romantic evaluations with a small effect size (r = ~.10) for both sexes. Sex differences in the correlations were small (r_difference = .03) and uniformly nonsignificant.

How Important is Physical Attractiveness in the Marriage Market: http://www.reis.cis.es/REIS/PDF/REIS_159_07_ENGLISH1499424514902.pdf
For men, the results show that being unattractive decreases the likelihood of finding a partner, of finding a partner with a university degree, and of finding a partner with a higher educational level. For women, physical attractiveness does not affect the likelihood of any of those events occurring. The study has also found out that physical attractiveness has more of an influence on people with a working class background to find a partner with higher educational attainment. These results are unexpected and pose a challenge to the theory of erotic capital.

Beliefs about Gender
We find that participants greatly overestimate not only their own ability but also that of others, suggesting that miscalibration is a substantial, first order factor in stated beliefs. Women are better calibrated than men, providing more accurate estimates of ability both for themselves and for others. Gender stereotypes also have strong predictive power for beliefs, particularly for men’s beliefs about themselves and others’ beliefs about the ability of men. Our findings help interpret evidence on gender gaps in self-confidence.

Genetic Consequences of Assortative Mating for Psychiatric Traits | Genetics and Genomics | JAMA Psychiatry | The JAMA Network
Phenotypic assortment results in increased genetic variance in the offspring generation, which may result in increased heritability and population prevalence. These consequences add generation after generation to a limit, but assortative mating is unlikely to balance the impact of reduced fecundity of patients with psychiatric disorders in the long term. This modeling suggests that the heritabilities of psychiatric disorders are unlikely to increase by more than 5% from 1 generation of assortative mating (maximally 13% across multiple generations).

After the intake of cow milk, serum estrone (E1) and progesterone concentrations significantly increased, and serum luteinizing hormone, follicle-stimulating hormone and testosterone significantly decreased in men. Urine concentrations of E1, estradiol, estriol and pregnanediol significantly increased in all adults and children. In four out of five women, ovulation occurred during the milk intake, and the timing of ovulation was similar among the three menstrual cycles.

"Thus, all countries except the most patient have negative net worth and negative holdings of net foreign assets: the most patient country holds title to all capital flows from the less patient. Consumption per unit of effective labor approaches zero (kept from zero consumption only by the Inada condition) because income flows are devoted to debt repayment. Indeed, in steady state all but the most patient country have savings rates near 100%—but these savings are mere debt repayments to the most patient country. In this steady state, the most patient country (or more realistically, countries) would continue to consume a non-negligible amount and would have the lowest savings rate(s) in the world."

The Genetic Correlation between Height and IQ: Shared Genes or Assortative Mating?
Both traits were highly heritable, although there was greater evidence for non-additive genetic effects in males. After accounting for assortative mating, the correlation between height and IQ was found to be almost entirely genetic in nature. Model fits indicate that both pleiotropy and assortative mating contribute significantly and about equally to this genetic correlation.

Talkin’ ’bout their generations | West Hunter
According to the Decode results, mothers contribute 15 mutations, regardless of age, while men contribute 25 + 2*(g-20) mutations, when g is the average paternal age. As I pointed out earlier, if g is the same in both sexes, the average number of mutations is just 2g, which makes for 2 mutations per calendar year. I’ve been checking out average maternal age: it doesn’t vary much. The lowest I’ve seen was 26, the highest 30, so 28 is a reasonable number. So far, in the data we’ve gathered, the population with the highest paternal age was in Gambia, with an average paternal age of 47. If we assume that the average maternal age is 28 (which look about right from the graph: I haven’t digitized it yet) then the average kid would receive 94 new mutations (15 maternal, 79 paternal). With an average generation length of 37.5 years (the average of 28 and 47), that makes for 2.5 mutations per calendar year: about 15% higher than you would see in most populations, where the gap between average maternal and paternal age is not nearly as large.

A Gambia-sized gap would result in a noticeably higher rate of neutral genetic divergence. If it had existed long enough you might be able to notice it, but I think there’s a better chance of seeing this effect in Australian Aborigines, who had high average paternal age and might have had it for a long time. Other than the Australians, I would guess that all the old-dad societies are relatively recent.

The higher mutational load is not just a consequence of the higher per-year mutation rate in these old-dad societies – since generations are longer, there is less selection per calendar year (considering that most selection acts early in life). The number of mutations per generation is probably the most important number. I found some numbers for Polar Eskimos, hunter-gatherers (they gather snow) in a tough environment: average maternal age was 27, average paternal age was 32, for an average generation length of 29.5. They’d have 64 mutations a generation: the per-generation rate in Gambia is 47% higher.

There are also qualitative differences in selection: selection is weaker in childhood and stronger in midlife in an old-dad society, as Henry pointed out. So that situation should select for longer life, except that’s hard to manage in the presence of higher-than-usual genetic load.

https://westhunt.wordpress.com/2012/10/19/base-substitutions-and-deletions/
According to Jim Crow”s 2006 article, base substitutions are mostly (overwhelmingly) from males and increase with paternal age, but small deletions are contributed about equally by males and females, with no noticeable age effect. Probably the deletions happen during meiosis.

So, with a huge gene like those involved in Duchenne’s muscular dystrophy or neurofibromatosis I, which have many exons (79 for dystrophin), many of the mutations are caused by deletions. The paternal age effect is weaker for those syndromes (since less than half of the causal mutations are base substitutions)

https://westhunt.wordpress.com/2012/09/16/paternal-age-and-the-force-of-mortality/
No surprises here save one. While selection for survival should extend male lifespans by 10 to 20 years in the case of old fathers, selection for survival before the age of reproduction is much weaker in the the case of older fathers. A prediction is that adolescent and young male death rates should be higher in old father societies because selection is weaker. I never realized that.

Hamilton’s theory does not describe human life history very well, as Rogers shows in his Figure 16.1 and discusses in the text. Human female fertility ceases long before the theory predicts that it should and humans live much longer. The reconciliation certainly has to do with kin selection or indirect selection. For example Kris Hawkes pushes the “grandmother hypothesis” according to which females cease reproduction and instead work for their daughters’ children. If she is right this grandmother effect selected for the prolonged human lifespan, and the long lifespan of males is a side-effect of selection for long life in females.

“By contrast, the average number of surviving children for the majority of men was probably somewhere between zero and one – despite that they were having sex and babies.”

Fuck me, that’s obviously ridiculous. In real life, take a peasant village in England: if your model were correct, you’d have surname turnover every couple of generations. But that didn’t happen.

Here’s a model that’s at least in the ballpark: there was some class differential in fitness. The poorest, landless laborers, had a TFR below replacement, but not by a tremendous amount: 1.6? Most peasants were close to break-even, upper farmers did better than break-even, Other groups were mostly too small in number or too urban (population sinks) to matter. Overall TFR was of course break-even over the moderately long haul, in a sloppy way, with occasional epidemics and crop failures.

Genetics and the Historical Decline of Violence?: https://westhunt.wordpress.com/2012/11/25/genetics-and-the-historical-decline-of-violence/
In the present case we need a response of 1/28 of a standard deviation per generation. Assuming an additive heritability of 0.5 (the true value is probably 0.8 or so from literature on the heritability of aggressive behavior in children) the selective differential must be about 1/14 or .07 standard deviations per generation. In terms of IQ this would correspond to a one point IQ advantage of parents over the population average and in terms of stature parents with a mean stature 0.2 inches greater than the population average. This would occur if the most homicidal 1.5% of the population were to fail to reproduce each generation.

I have no reason to believe that this was planned. If you look at the trend today, you might get the impression that the powers that be are actively trying to increase the fitness of assholes, but I doubt if that is the case. Sure, that’s the effect, but they don’t know enough to do it on purpose.

For example, when the Supremes decided that being sufficiently stupid is a get-out-of-execution card, they weren’t thinking about long-term biological implications. I doubt if they ever do, or can.

A thought experiment: in the light of behavioral genetics, what should you do when it’s clear that one of a pair of identical twins has committed a truly heinous crime – but you don’t know which one?

This really is a matter of chickens coming home to roost. There has been a tension since the 60’s about what we want police to do. We no longer have fit men with a strong capacity for violence occupying the majority of patrol cars in this country. What we have been slipping towards for decades are a mass of armed social workers with a small force of violent proficient SWAT guys who are supposed to save the day when bad things really, really need to happen but are never there when you really need them.

...

Finally, our society needs to adjust its attitudes towards violence. There is the recently coined term “pro-social violence” which is used to describe “lawful, moral violence in the service of good.” We need to restore the idea that when violent things happen to bad people, it’s OK and society is better as a whole.

Divorce and children’s long-term outcomes | VOX, CEPR’s Policy Portal
It has been widely demonstrated that parental divorce is associated with negative outcomes for affected children. However, the degree of causality in this relationship is not as clear. This column tackles this problem by using the level of gender integration in fathers’ workplaces as an instrument for divorce. The results suggest a causal link between divorce and worse economic outcomes that persists into early adulthood.

The literature on father absence is frequently criticized for its use of cross-sectional data and methods that fail to take account of possible omitted variable bias and reverse causality. We review studies that have responded to this critique by employing a variety of innovative research designs to identify the causal effect of father absence, including studies using lagged dependent variable models, growth curve models, individual fixed effects models, sibling fixed effects models, natural experiments, and propensity score matching models. Our assessment is that studies using more rigorous designs continue to find negative effects of father absence on offspring well-being, although the magnitude of these effects is smaller than what is found using traditional cross-sectional designs. The evidence is strongest and most consistent for outcomes such as high school graduation, children’s social-emotional adjustment, and adult mental health.

Genetics, the Rearing Environment, and the Intergenerational Transmission of Divorce: A Swedish National Adoption Study: http://journals.sagepub.com/doi/abs/10.1177/0956797617734864
There was stronger resemblance to lived-with mothers, providing indirect evidence of rearing-environment influences on the intergenerational transmission of divorce. The heritability of divorce assessed across generations was 0.13. We attempted to replicate our findings using within-generation data from adoptive and biological siblings (ns = 8,523–53,097). Adoptees resembled their biological, not adoptive, siblings in their history of divorce. Thus, there was consistent evidence that genetic factors contributed to the intergenerational transmission of divorce but weaker evidence for a rearing-environment effect of divorce. Within-generation data from siblings supported these conclusions.

The Long-Term Effects of Legalizing Divorce on Children: http://onlinelibrary.wiley.com/doi/10.1111/obes.12200/abstract
We find that women who grew up under legal divorce have lower earnings and income and worse health as adults compared with women who grew up under illegal divorce. These negative effects are not found for men.
