Friends with malefit. The effects of keeping dogs and cats, sustaining animal-related injuries and Toxoplasma infection on health and quality of life | bioRxiv
The main problem of many studies was the autoselection – participants were informed about the aims of the study during recruitment and later likely described their health and wellbeing according to their personal beliefs and wishes, not according to their real status. To avoid this source of bias, we did not mention pets during participant recruitment and hid the pet-related questions among many hundreds of questions in an 80-minute Internet questionnaire. Results of our study performed on a sample of on 10,858 subjects showed that liking cats and dogs has a weak positive association with quality of life. However, keeping pets, especially cats, and even more being injured by pets, were strongly negatively associated with many facets of quality of life. Our data also confirmed that infection by the cat parasite Toxoplasma had a very strong negative effect on quality of life, especially on mental health. However, the infection was not responsible for the observed negative effects of keeping pets, as these effects were much stronger in 1,527 Toxoplasma-free subjects than in the whole population. Any cross-sectional study cannot discriminate between a cause and an effect. However, because of the large and still growing popularity of keeping pets, the existence and nature of the reverse pet phenomenon deserve the outmost attention.

The End of the Editor Wars » Linux Magazine
Moreover, even if you assume a broad margin of error, the pollings aren't even close. With all the various text editors available today, Vi and Vim continue to be the choice of over a third of users, while Emacs well back in the pack, no longer a competitor for the most popular text editor.

https://www.quora.com/Are-there-more-Emacs-or-Vim-users
I believe Vim is actually more popular, but it's hard to find any real data on it. The best source I've seen is the annual StackOverflow developer survey where 15.2% of developers used Vim compared to a mere 3.2% for Emacs.

Oddly enough, the report noted that "Data scientists and machine learning developers are about 3 times more likely to use Emacs than any other type of developer," which is not necessarily what I would have expected.

[ed. NB: Vim still dominates overall.]

Time To End The vi/Emacs Debate: https://cacm.acm.org/blogs/blog-cacm/226034-time-to-end-the-vi-emacs-debate/fulltext

Vim, Emacs and their forever war. Does it even matter any more?: https://blog.sourcerer.io/vim-emacs-and-their-forever-war-does-it-even-matter-any-more-697b1322d510
Like an episode of “Silicon Valley”, a discussion of Emacs vs. Vim used to have a polarizing effect that would guarantee a stimulating conversation, regardless of an engineer’s actual alignment. But nowadays, diehard Emacs and Vim users are getting much harder to find. Maybe I’m in the wrong orbit, but looking around today, I see that engineers are equally or even more likely to choose any one of a number of great (for any given definition of ‘great’) modern editors or IDEs such as Sublime Text, Visual Studio Code, Atom, IntelliJ (… or one of its siblings), Brackets, Visual Studio or Xcode, to name a few. It’s not surprising really — many top engineers weren’t even born when these editors were at version 1.0, and GUIs (for better or worse) hadn’t been invented.

...

… both forums have high traffic and up-to-the-minute comment and discussion threads. Some of the available statistics paint a reasonably healthy picture — Stackoverflow’s 2016 developer survey ranks Vim 4th out of 24 with 26.1% of respondents in the development environments category claiming to use it. Emacs came 15th with 5.2%. In combination, over 30% is, actually, quite impressive considering they’ve been around for several decades.

What’s odd, however, is that if you ask someone — say a random developer — to express a preference, the likelihood is that they will favor for one or the other even if they have used neither in anger. Maybe the meme has spread so widely that all responses are now predominantly ritualistic, and represent something more fundamental than peoples’ mere preference for an editor? There’s a rather obvious political hypothesis waiting to be made — that Emacs is the leftist, socialist, centralized state, while Vim represents the right and the free market, specialization and capitalism red in tooth and claw.

How is Emacs/Vim used in companies like Google, Facebook, or Quora? Are there any libraries or tools they share in public?: https://www.quora.com/How-is-Emacs-Vim-used-in-companies-like-Google-Facebook-or-Quora-Are-there-any-libraries-or-tools-they-share-in-public
In Google there's a fair amount of vim and emacs. I would say at least every other engineer uses one or another.

Among Software Engineers, emacs seems to be more popular, about 2:1. Among Site Reliability Engineers, vim is more popular, about 9:1.
--
People use both at Facebook, with (in my opinion) slightly better tooling for Emacs than Vim. We share a master.emacs and master.vimrc file, which contains the bare essentials (like syntactic highlighting for the Hack language). We also share a Ctags file that's updated nightly with a cron script.

Beyond the essentials, there's a group for Emacs users at Facebook that provides tips, tricks, and major-modes created by people at Facebook. That's where Adam Hupp first developed his excellent mural-mode (ahupp/mural), which does for Ctags what iDo did for file finding and buffer switching.
--
For emacs, it was very informal at Google. There wasn't a huge community of Emacs users at Google, so there wasn't much more than a wiki and a couple language styles matching Google's style guides.

https://trends.google.com/trends/explore?date=all&geo=US&q=%2Fm%2F07zh7,%2Fm%2F01yp0m

https://www.quora.com/Why-is-interest-in-Emacs-dropping
And it is still that. It’s just that emacs is no longer unique, and neither is Lisp.

Dynamically typed scripting languages with garbage collection are a dime a dozen now. Anybody in their right mind developing an extensible text editor today would just use python, ruby, lua, or JavaScript as the extension language and get all the power of Lisp combined with vibrant user communities and millions of lines of ready-made libraries that Stallman and Steele could only dream of in the 70s.

In fact, in many ways emacs and elisp have fallen behind: 40 years after Lambda, the Ultimate Imperative, elisp is still dynamically scoped, and it still doesn’t support multithreading — when I try to use dired to list the files on a slow NFS mount, the entire editor hangs just as thoroughly as it might have in the 1980s. And when I say “doesn’t support multithreading,” I don’t mean there is some other clever trick for continuing to do work while waiting on a system call, like asynchronous callbacks or something. There’s start-process which forks a whole new process, and that’s about it. It’s a concurrency model straight out of 1980s UNIX land.

But being essentially just a decent text editor has robbed emacs of much of its competitive advantage. In a world where every developer tool is scriptable with languages and libraries an order of magnitude more powerful than cranky old elisp, the reason to use emacs is not that it lets a programmer hit a button and evaluate the current expression interactively (which must have been absolutely amazing at one point in the past).

https://www.quora.com/Why-is-Vim-the-programmers-favorite-editor
- Adrien Lucas Ecoffet,

Because it is hard to use. Really.

However, the second part of this sentence applies to just about every good editor out there: if you really learn Sublime Text, you will become super productive. If you really learn Emacs, you will become super productive. If you really learn Visual Studio… you get the idea.

Here’s the thing though, you never actually need to really learn your text editor… Unless you use vim.

...

For many people new to programming, this is the first time they have been a power user of… well, anything! And because they’ve been told how great Vim is, many of them will keep at it and actually become productive, not because Vim is particularly more productive than any other editor, but because it didn’t provide them with a way to not be productive.

They then go on to tell their friends how great Vim is, and their friends go on to become power users and tell their friends in turn, and so forth. All these people believe they became productive because they changed their text editor. Little do they realize that they became productive because their text editor changed them[1].

This is in no way a criticism of Vim. I myself was a beneficiary of such a phenomenon when I learned to type using the Dvorak layout: at that time, I believed that Dvorak would help you type faster. Now I realize the evidence is mixed and that Dvorak might not be much better than Qwerty. However, learning Dvorak forced me to develop good typing habits because I could no longer rely on looking at my keyboard (since I was still using a Qwerty physical keyboard), and this has made me a much more productive typist.

Technical Interview Performance by Editor/OS/Language: https://triplebyte.com/blog/technical-interview-performance-by-editor-os-language
[ed.: I'm guessing this is confounded to all hell.]

The #1 most common editor we see used in interviews is Sublime Text, with Vim close behind.

Emacs represents a fairly small market share today at just about a quarter the userbase of Vim in our interviews. This nicely matches the 4:1 ratio of Google Search Trends for the two editors.

...

Vim takes the prize here, but PyCharm and Emacs are close behind. We’ve found that users of these editors tend to pass our interview at an above-average rate.

On the other end of the spectrum is Eclipse: it appears that someone using either Vim or Emacs is more than twice as likely to pass our technical interview as an Eclipse user.

...

In this case, we find that the average Ruby, Swift, and C# users tend to be stronger, with Python and Javascript in the middle of the pack.

...

Here’s what happens after we select engineers to work with and send them to onsites:

[Python does best.]

There are no wild outliers here, but let’s look at the C++ segment. While C++ programmers have the most challenging time passing Triplebyte’s technical interview on average, the ones we choose to work with tend to have a relatively easier time getting offers at each onsite.

The Rise of Microsoft Visual Studio Code: https://triplebyte.com/blog/editor-report-the-rise-of-visual-studio-code

maintenance - Why do dynamic languages make it more difficult to maintain large codebases? - Software Engineering Stack Exchange
Now here is the key point I have been building up to: there is a strong correlation between a language being dynamically typed and a language also lacking all the other facilities that make lowering the cost of maintaining a large codebase easier, and that is the key reason why it is more difficult to maintain a large codebase in a dynamic language. And similarly there is a correlation between a language being statically typed and having facilities that make programming in the larger easier.

Use and Interpretation of LD Score Regression
LD Score regression distinguishes confounding from polygenicity in genome-wide association studies: https://sci-hub.bz/10.1038/ng.3211
- Po-Ru Loh, Nick Patterson, et al.

https://www.biorxiv.org/content/biorxiv/early/2014/02/21/002931.full.pdf

Both polygenicity (i.e. many small genetic effects) and confounding biases, such as cryptic relatedness and population stratification, can yield inflated distributions of test statistics in genome-wide association studies (GWAS). However, current methods cannot distinguish between inflation from bias and true signal from polygenicity. We have developed an approach that quantifies the contributions of each by examining the relationship between test statistics and linkage disequilibrium (LD). We term this approach LD Score regression. LD Score regression provides an upper bound on the contribution of confounding bias to the observed inflation in test statistics and can be used to estimate a more powerful correction factor than genomic control. We find strong evidence that polygenicity accounts for the majority of test statistic inflation in many GWAS of large sample size.

Red State Families: Better Than We Knew | Institute for Family Studies
Second, adjusting for education and race/ethnicity transforms the relationship between the Red State Index and marital upbringing from a curvilinear to a linear one. The redder the state, the more likely is a teen to grow up with his or her married birth parents. The relationship is modest but statistically significant. For every ten-point increase in the Red State Index, the proportion of teens living with both parents rises by one percentage point. This suggests that red state family culture is associated with increased odds of being raised in an intact, married family.

1 Genetics and Crime
The broader construct of antisocial behavior – which includes criminal offending, as well as aggression – also shows substantial genetic influence. In a meta-analysis combining effect sizes in 51 twin and adoption studies, Rhee and Waldman (2002) reported a heritability estimate of 41 per cent, with the remaining 59 per cent of variance being due to environmental factors. Interestingly, when comparing results for various definitions of antisocial behavior, only criminal offending appeared to be influenced by both additive genetic effects and non-additive genetic effects – possibly due to genetic dominance and epistatic interactions between genes – based on a pattern of results whereby, on average, identical (monozygotic) twin correlations are more than twice the value of fraternal (dizygotic) twin correlations, and also that biological parent–offspring correlations are less than fraternal twin correlations. Such non-additive genetic effects could arise if one or more high risk alleles act in a recessive fashion, or if certain alleles at one locus affect gene expression at other loci (epistasis).

One intriguing aspect of the literature on genetics and crime is that the strong and consistent genetic influence seen for property offending does not hold true for violent criminal convictions. None of the major adoption studies in Scandinavia or the United States found any elevated risk for violent convictions as a function of either biological or adoptive parent criminal offending, although one early twin study did find greater identical (monozygotic) than fraternal (dizygotic) concordance for violent convictions (see Cloninger and Gottesman, 1987). This pattern of twin, but not parent-offspring, similarity for violent criminal behavior suggests the possibility of non-additive genetic effects due to dominance or epistasis, which would result in increased resemblance for siblings (and twins), but not for parents and offspring. Thus, there may be genetic risk for violent crimes such as murder and rape, which may stem from rare recessive genes, or specific combinations of alleles that do not appear in studies of vertical transmission across generations.

A Swedish national twin study of criminal behavior and its violent, white-collar and property subtypes: https://www.cambridge.org/core/journals/psychological-medicine/article/a-swedish-national-twin-study-of-criminal-behavior-and-its-violent-white-collar-and-property-subtypes/0D9A88185ED0FD5525A5EBD5D2EBA117
For all criminal convictions, heritability was estimated at around 45% in both sexes, with the shared environment accounting for 18% of the variance in liability in females and 27% in males. The correlation of these risk factors across sexes was estimated at +0.63. In men, the magnitudes of genetic and environmental influence were similar in the three criminal conviction subtypes. However, for violent and white-collar convictions, nearly half and one-third of the genetic effects were respectively unique to that criminal subtype. About half of the familial environmental effects were unique to property convictions.

Heritability, Assortative Mating and Gender Differences in Violent Crime: Results from a Total Population Sample Using Twin, Adoption, and Sibling Models: https://link.springer.com/article/10.1007/s10519-011-9483-0
Using 36k twins, violent crime was moderately heritable (~ 55%) w/ 13% shared environment influence. Using 1.5 mil siblings, heritability was higher for males, & family environment higher for females. Moderate assortative mating for violent crime (r = .4).

In the crude model, an increase of 1 SD in neighbourhood deprivation was associated with a 57% increase in the odds of being convicted of a violent crime (95% CI 52%–63%). The effect was greatly attenuated when adjustment was made for a number of observed confounders (OR 1.09, 95% CI 1.06–1.11). When we additionally adjusted for unobserved familial confounders, the effect was no longer present (OR 0.96, 95% CI 0.84–1.10). Similar results were observed for substance misuse. The results were not due to poor variability either between neighbourhoods or within families.

What did surprise him was that when he looked at families which had started poor and got richer, the younger children—those born into relative affluence—were just as likely to misbehave when they were teenagers as their elder siblings had been. Family income was not, per se, the determining factor.

Three indicators of IPV were measured and genetic factors accounted for 24% of the variance in hitting one's partner, 54% of the variance in injuring one's partner, and 51% of the variance in forcing sexual activity on one's partner. The shared environment explained none of the variance across all three indicators and the nonshared environment explained the remainder of the variance.

Social Animal House: The Economic and Academic Consequences of Fraternity Membership by Jack Mara, Lewis Davis, Stephen Schmidt :: SSRN
We exploit changes in the residential and social environment on campus to identify the economic and academic consequences of fraternity membership at a small Northeastern college. Our estimates suggest that these consequences are large, with fraternity membership lowering student GPA by approximately 0.25 points on the traditional four-point scale, but raising future income by approximately 36%, for those students whose decision about membership is affected by changes in the environment. These results suggest that fraternity membership causally produces large gains in social capital, which more than outweigh its negative effects on human capital for potential members. Alcohol-related behavior does not explain much of the effects of fraternity membership on either the human capital or social capital effects. These findings suggest that college administrators face significant trade-offs when crafting policies related to Greek life on campus.

Do High School Sports Build or Reveal Character?: http://ftp.iza.org/dp11110.pdf
We examine the extent to which participation in high school athletics has beneficial effects on future education, labor market, and health outcomes. Due to the absence of plausible instruments in observational data, we use recently developed methods that relate selection on observables with selection on unobservables to estimate bounds on the causal effect of athletics participation. We analyze these effects in the US separately for men and women using three different nationally representative longitudinal data sets that each link high school athletics participation with later-life outcomes. We do not find consistent evidence of individual benefits reported in many previous studies – once we have accounted for selection, high school athletes are no more likely to attend college, earn higher wages, or participate in the labor force. However, we do find that men (but not women) who participated in high school athletics are more likely to exercise regularly as adults. Nevertheless, athletes are no less likely to be obese.

Online Social Network Effects in Labor Markets: Evidence From Facebook's Entry into College Campuses: https://papers.ssrn.com/sol3/papers.cfm?abstract_id=3381938
My estimates imply that access to Facebook for 4 years of college causes a 2.7 percentile increase in a cohort's average earnings, relative to the earnings of other individuals born in the same year.

https://marginalrevolution.com/marginalrevolution/2019/05/might-facebook-boost-wages.html
What Clockwork_Prior said. I was a college freshman when facebook first made its appearance and so I know that facebook's entry/exit cannot be treated as a quasi-random with respect to earnings. Facebook began at harvard, then expanded to other ivy league schools + places like stanford/MIT/CMU, before expanding into a larger set of universities.

Presuming the author is using a differences-in-differences research design, the estimates would be biased as they would essentially be calculating averaging earnings difference between Elite schools and non elite schools. If the sample is just restricted to the period where schools were simply elite, the problem still exist because facebook originated at Harvard and this becomes a comparison of Harvard earnings v.s. other schools.

Fear and Loathing in Psychology - The Unz Review
Warne and Astle looked at 29 best-selling undergraduate textbooks, which is where psychology students learn about intelligence, because less than 10% of graduate courses offer an intelligence option.

3.3% of textbook space is dedicated to intelligence. Given its influence, this is not very much.

The most common topics start well, with IQ and Spearman’s g, but do not go on to the best validated, evidence-led Cattell-Horn-Carol meta-analytic summary, but a side-stream, speculative triarchic theory from Sternberg; and a highly speculative and non-specific sketch of an idea about multiple intelligences Gardner. The last is a particular puzzle, since it really is a whimsical notion that motor skill is no different from analytical problem solving. All must have prizes.
Commonly, environmental influences are discussed, genetic ones rarely.

Twenty-four leading introductory psychology textbooks were surveyed for their coverage of a number of controversial topics (e.g., media violence, narcissism epidemic, multiple intelligences) and scientific urban legends (e.g., Kitty Genovese, Mozart Effect) for their factual accuracy. Results indicated numerous errors of factual reporting across textbooks, particularly related to failing to inform students of the controversial nature of some research fields and repeating some scientific urban legends as if true. Recommendations are made for improving the accuracy of introductory textbooks.

Mapping the scale of the narcissism epidemic: Increases in narcissism 2002–2007 within ethnic groups: https://www.sciencedirect.com/science/article/pii/S0092656608000949

The increasing numbers of Asian-Americans at the UCs over time may have masked changes in narcissism, as Asian-Americans score lower on the NPI. When examined within ethnic groups, Trzesniewski et al.’s data show that NPI scores increased significantly between 2002 and 2007 at twice the rate of the yearly change found over 24 years in Twenge et al. (2008a). The overall means also show a significant increase 2002–2007. Thus the available evidence suggests that college students are endorsing progressively more narcissistic personality traits over the generations.

Birth Cohort Increases in Narcissistic Personality Traits Among American College Students, 1982–2009: http://journals.sagepub.com/doi/abs/10.1177/1948550609355719

Both studies demonstrate significant increases in narcissism over time (Study 1 d = .37, 1982–2008, when campus is controlled; Study 2 d = .37, 1994–2009). These results support a generational differences model of individual personality traits reflecting changes in culture.

The myth of London exceptionalism: https://quarterly.demos.co.uk/article/issue-5/ukip-in-london/
London is not as invulnerable to the appeal of UKIP as commonly reported, finds new research from Eric Kaufmann.

Are White British Londoners more accepting of immigration than White British elsewhere? The British Election Study (BES)’s 2015 panel survey asks whether immigration enriches or undermines cultural life. 34.7 per cent of White British outside London say immigration strongly undermines cultural life. But so do 34.4 per cent of White British Londoners. Not much difference there. 44 per cent of White Brits outside London want to leave the EU, but so do 42.3 per cent of White British Londoners. Again, not much in it.

Finally, when we control for a fuller range of demographic and attitudinal characteristics, as in figure 4, London and the South East emerge as significantly more likely than the rest of England and Wales to have voted UKIP in 2014, according to the BES.

Diverging Life Expectancies and Voting Patterns in the 2016 US Presidential Election.: https://www.ncbi.nlm.nih.gov/pubmed/28817322
Changes in county life expectancy from 1980 to 2014 were strongly negatively associated with Trump's vote share, with less support for Trump in counties experiencing greater survival gains. Counties in which life expectancy stagnated or declined saw a 10-percentage-point increase in the Republican vote share between 2008 and 2016.

WE’VE BEEN HERE BEFORE: https://spottedtoad.wordpress.com/2018/01/12/weve-been-here-before/
A concept that seems to me to be missing from the Ruhm vs. Case/Deaton debate on “deaths of despair” is that of social crisis.

This seems to me to be the case for American Indians, who began experiencing what looks like a similar social crisis to non-college educated whites about a decade beforehand: rapidly escalating rates of suicide, drug overdoses, exit from the workforce, and even alcohol-related deaths (which were already very high for American Indians well before 2000, of course):

...

The common thread here would seem to be replacement of workforce participation with transfer payments, particularly cash transfers (since, my own reservations about Medicaid aside, increases in in-kind payments and SNAP since the 80s haven’t seemed to exert the same disruptive effect.) As I’ve said before, it seems very likely to me that technology will push an ever larger segment of society out of the economy, sooner or later, but how to prevent this from tearing apart our social fabric I don’t know.

In electoral terms, age seems to be the new dividing line in British politics.

Amongst those aged over 70, the Conservatives had a lead of fifty percentage points.

John Curtice is explaining that Labour’s economic policies did almost nothing to galvanise the young. It was their social liberalism.
Older voters more likely to care about rent control or redistribution than young.
Tuition fees are a misdiagnosis.
It’s SOCIAL LIBERALISM.
“In many ways the cues and mood music are more important than the policy.”
“The prominence of social issues have never been as big a dimension as they played in 2017.
Neither had the disparity in age.”

great title

In this paper I try to move away from the Extreme Bounds method of identifying" Instead of analyzing the" extreme bounds of the estimates of the coefficient of a particular variable distribution. My claim in this paper is that, if we do this, the picture emerging from the" empirical growth literature is not the pessimistic Robust" that we get with the" extreme bound analysis. Instead, we find that a substantial number of variables can be found" to be strongly related to growth.

Are the Rich More Selfish than the Poor, or Do They Just Have More Money? A Natural Field Experiment
We present new evidence from a natural field experiment in which we “misdeliver” envelopes to rich and poor households in a Dutch city, varying their contents to identify motives for returning them. Our raw data indicate the rich behave more pro-socially. Controlling for pressures associated with poverty and the marginal utility of money, however, we find no difference in social preferences. The primary distinction between rich and poor is simply that the rich have more money.

also, apparently the Netherlands has highest wealth inequality in Europe (anglo-dutch heritage?)

The Origins of Cognitive Deficits in Victimized Children: Implications for Neuroscientists and Clinicians | American Journal of Psychiatry
Individuals exposed to childhood victimization had pervasive impairments in clinically relevant cognitive functions, including general intelligence, executive function, processing speed, memory, perceptual reasoning, and verbal comprehension in adolescence and adulthood. However, the observed cognitive deficits in victimized individuals were largely explained by cognitive deficits that predated childhood victimization and by confounding genetic and environmental risks.

Large Cross-National Differences in Gene × Socioeconomic Status Interaction on Intelligence : slatestarcodex

- nontrivial positive interactions in US, zero or negative in western Europe/Australia (more effective/expansive welfare state probably)
- in particular: heritability estimates for IQ are notably lower for low SES populations in the US
- JayMan had some objections (on James Thompson's blog), w/ the strongest-looking one being that SES is not a good metric compared to income because of confounding, but I'm not sure whether that makes sense. And the cross-country differences seem like a strong rejoinder.

From Swords to Words: Does Macro-Level Change in Self-Control Predict Long-Term Variation in Levels of Homicide?: https://www.researchgate.net/publication/264402032_From_Swords_to_Words_Does_Macro-Level_Change_in_Self-Control_Predict_Long-Term_Variation_in_Levels_of_Homicide
Over the past decade the idea that Europe experienced a centuries-long decline in homicide, interrupted by recurrent surges and at different speeds in different parts of the continent, became widely acknowledged. So far explanations have relied mostly on anecdotal evidence, usually broadly relying on Norbert Elias's theory of the "civilizing process." One major general theory of large-scale fluctuations in homicide rates, self-control theory, offers a wide range of hypotheses that can be tested with rigorous quantitative analyses. A number of macro-level indicators for so-cietal efforts to promote civility, self-discipline, and long-sightedness have been examined and appear to be strongly associated with fluctuations in homicide rates over the past six centuries.

Population has doubled.
"more serious wounding" has gone up 60 times. (So, 30 times per cap.)
Murder has only doubled. 300ish to 700ish. So, roughly in line with population. However, WWI and WWII dramatically improved trauma medicine. That's why 'wounding' can go up 30 times and murder stays constant.

Physical activity in adulthood: genes and mortality : Scientific Reports
Observational studies report a strong inverse relationship between leisure-time physical activity and all-cause mortality. Despite suggestive evidence from population-based associations, scientists have not been able to show a beneficial effect of physical activity on the risk of death in controlled intervention studies among individuals who have been healthy at baseline. On the other hand, high cardiorespiratory fitness is known to be a strong predictor of reduced mortality, even more robust than physical activity level itself. Here, in both animals and/or human twins, we show that the same genetic factors influence physical activity levels, cardiorespiratory fitness, and risk of death. Previous observational follow-up studies in humans suggest that increasing fitness through physical activity levels could prolong life; however, our controlled interventional study with laboratory rats bred for low and high intrinsic fitness contrast with these findings. Also, we find no evidence for the suggested association using pairwise analysis among monozygotic twin pairs who are discordant in their physical activity levels. Based on both our animal and human findings, we propose that genetic pleiotropy might partly explain the frequently observed associations between high baseline physical activity and later reduced mortality in humans.

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.
http://ftp.iza.org/dp9928.pdf

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3904543/
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.

Achilles and the Tortoise Talk About Floss – spottedtoad
Exactly- people already want their teeth to be clean. People already can afford floss if they want to get it. People already have been told their whole life, more-or-less, that they should floss. To a large degree, if they’re the kind of person who can follow through with flossing, they’re already doing it. So if you go and put up signs around your medical school telling people they can get paid for a study of flossing if they don’t already floss and then you randomly assign them to be told to floss or not, you’re not testing the effect of flossing, you’re testing the effect of being told one more time to floss if you’ve already proved that you don’t like to do it. Maybe it’s not even that good for you personally, but that doesn’t mean it’s not good for most people who are already flossing.

The Influence of Glycemic Index on Cognitive Functioning: A Systematic Review of the Evidence
The primary outcome measure was the effect on cognitive function (CF) after the consumption of meals varying in GI. Eleven eligible studies were identified. The age range of the participants varied from 6 to 82 y old. Overall, the findings were inconsistent, with some studies showing benefits toward either the high-GI or the low-GI meal, others not finding any differences between the 2 meals, and other studies showing a positive or negative effect on performance on only some cognitive domain or domains after consumption of 1 of the 2 meals. A number of methodologic and confounding factors were identified that could explain these inconsistencies.

A Variant on “Statistically Controlling for Confounding Constructs is Harder than you Think”
It’s taken me some time to master this formalism, but I now find it quite easy to reason about these kinds of issues thanks to the brevity of graphical models as a notational technique. I’d love to see this approach become more popular in psychology, given that it has already become quite widespread in other fields. Of course, Westfall and Yarkoni are already advocating for something very similar by advocating for the use of SEM’s, but the graphical approach is strictly more general than SEM’s and, in my personal opinion, strictly simpler to reason about.
