Secular rise in economically valuable personality traits
small decline starting at YOB~1980:
Growing evidence suggests that the Flynn effect has ended and may have reversed in Western Europe (32, 33, 44–46). The last three birth cohorts in our data coincide with the peak in cognitive test scores in Finland (31). There is no clear trend for personality scores between these cohorts, which suggests that the end of the Flynn effect could also be reflected in personality traits. However, the data on these three birth cohorts are not fully comparable with our main data, and thus, it is not possible to make strong conclusions from them.

Whose Job Will Be Taken Over by a Computer? The Role of Personality in Predicting Job Computerizability over the Lifespan - Damian - 2017 - European Journal of Personality - Wiley Online Library
Multiple regressions showed that, regardless of social background, people who were more intelligent, mature, interested in arts, and sciences at baseline, and selected into jobs that had a lower probability of computerization. On average, a one standard deviation increase in each of these traits predicted an average of 4 percentage points drop in the probability of one's job of being computerized.

Personality predicts migration within and between U.S. states
High openness and low agreeableness increased within- and between-states migration, while high extraversion increased within- but not between-states migration. Conscientiousness and neuroticism were not related to migration probability.

The Distance Between Mars and Venus: Measuring Global Sex Differences in Personality
something other than Big Five

In an email, Del Giudice explained his approach to me with an analogy. “Gender differences in personality are very much like gender differences in facial appearance,” he said. “Each individual trait (nose length, eye size, etc) shows small differences between men and women, but once you put them all together... differences become clear and you can distinguish between male and female faces with more than 95% accuracy.”

Gender Differences in Personality across the Ten Aspects of the Big Five: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3149680/
Replicating previous findings, women reported higher Big Five Extraversion, Agreeableness, and Neuroticism scores than men. However, more extensive gender differences were found at the level of the aspects, with significant gender differences appearing in both aspects of every Big Five trait. For Extraversion, Openness, and Conscientiousness, the gender differences were found to diverge at the aspect level, rendering them either small or undetectable at the Big Five level.

Who delays childbearing? The relationships between fertility, education and personality traits
Given that nowadays women’s fertility reflects, to a greater extent, their basic preferences and that personality traits are intimately related to individual’s preferences, we expect to find an association between personality traits and fertility. Indeed, we find that whereas high levels of Agreeableness, Extroversion and Neuroticism accelerate childbirth, high levels of Conscientiousness and Openness are associated with childbirth postponement.

The nature of the relationship between education and postponement of fertility is far less clear. We explore two possible ways through which personality traits might help explain the fertility timing gap between more and less educated women: one is that some of the personality traits that drive some women to study more also influence their fertility behaviour; the other one is that individual differences in personality traits translate into variation in time to first birth especially among more educated women. Our results support both hypotheses i.e. on the one hand, personality traits influence both education and fertility decisions; on the other hand, more educated women do not equally delay childbirth compared with less educated women: the more “open-minded” ones postpone childbearing for longer.

Association of the Dopamine D4 Receptor (DRD4) Gene and Approach-Related Personality Traits: Meta-Analysis and New Data - Biological Psychiatry
Our initial meta-analysis supported the association of the DRD4 C-521T polymorphism, but not the VNTR polymorphism, with approach-related traits. This conclusion was qualified by evidence of significant publication bias and the failure to detect association in a replication sample comprising individuals at the extremes of the trait distribution. The association of the C-521T polymorphism observed in our initial meta-analysis was robust to the inclusion of these new data, but our revised meta-analysis indicated that the association was present for measures of novelty seeking and impulsivity but not for measures of extraversion.

Heritability of the Big Five Personality Dimensions and Their Facets: A Twin Study - Jang - 1996 - Journal of Personality - Wiley Online Library
Broad genetic influence on the five dimensions of Neuroticism, Extraversion, Openness, Agreeableness, and Conscientiousness was estimated at 41%, 53%, 61%, 41%, and 44%, respectively. The facet scales also showed substantial heritability, although for several facets the genetic influence was largely nonadditive. The influence of the environment was consistent across all dimensions and facets. Shared environmental influences accounted for a negligible proportion of the variance in most scales, whereas nonshared environmental influences accounted for the majority of the environmental variance in all scales.

A Systematic Review of Personality Trait Change Through Intervention
gwern: https://plus.google.com/103530621949492999968/posts/6kFWRkUTXSV
Messy (noticeable levels of publication bias, high heterogeneity), but results look plausible: 8-week+ interventions can improve emotional stability and neuroticism, change Openness and Extraversion somewhat, but leave Conscientiousness largely unaffected.

hbd chick/murray: https://twitter.com/hbdchick/status/818138228553302017

- 8-week intervention -> d=.37 after (an average of) 24 weeks
- after 8 weeks, strong diminishing returns
- pretty much entirely self-report
- good page-length discussion of limitations at end
- there was actually a nonzero effect for conscientiousness (~.2). not sure it would remain w/o publication bias.
- what's the difference between Table 2 and 3? I guess RCT vs. something else? why highlight Table 2 in abstract then?

Genome-wide analyses for personality traits identify six genomic loci and show correlations with psychiatric disorders : Nature Genetics : Nature Research
- a few for conscientiousness and neuroticism, several for extraversion
- specific SNPs linking conscientiousness and educational attainment, extraversion and low neuroticism
- neuroticism SNP located in region that is "related to innate immunity and the nervous system and [...] a potential hub for cancer and developmental neuropsychiatric disorders" (!!, X germ hypothesis!)
- neuroticism negatively correlated w/ other 4 personality factors (general positive personality factor?)
- ADHD strongly correlated w/ extraversion
- openness correlated w/ bipolar disorder and schizophrenia (and also depression)
- neuroticism correlated w/ depression
- conscientiousness protective against just about every disorder

Information Processing: Earnings effects of personality, education and IQ for the gifted
Of the personality factors, Conscientiousness and Extraversion had the largest (positive) effect on lifetime earnings: the most conscientious or extraverted individuals earned, on average, about 50% more than the least (see figures below).

- low agreeableness and low openness (!) relevant too
- as noted, restricted range of IQ, so would be more impactful in real world

The role of personality in individual differences in yearly earnings: http://www.sciencedirect.com/science/article/pii/S0191886917305962
Men reported they earned modestly more money than women did, as did married and fully employed people, but these three factors did not interact. Narcissism, psychopathy, extraversion, conscientiousness, and limited neuroticism predicted self-reported higher earnings; associations that differed little by participant's sex, although a slight pattern suggests women may pay a higher pay penalty for neuroticism but benefit more from conscientiousness than men do. Narcissism and neuroticism mediated sex differences in self-reported income suggesting men who were more narcissistic and women who were less neurotic reported more yearly earnings.

The capacity to be alone | Quomodocumque
In fact, most of these comrades who I gauged to be more brilliant than I have gone on to become distinguished mathematicians. Still from the perspective or thirty or thirty five years, I can state that their imprint upon the mathematics of our time has not been very profound. They’ve done all things, often beautiful things in a context that was already set out before them, which they had no inclination to disturb. Without being aware of it, they’ve remained prisoners of those invisible and despotic circles which delimit the universe of a certain milieu in a given era. To have broken these bounds they would have to rediscover in themselves that capability which was their birthright, as it was mine: The capacity to be alone.
