More “agreeable” men earn significantly less

“That is the topic of my latest Bloomberg column, here is one excerpt:

Gensowski revisits a data set from all schools in
California, grades 1-8, in 1921-1922, based on the students who scored
in the top 0.5 percent of the IQ distribution. At the time that meant
scores of 140 or higher. The data then cover how well these students,
856 men and 672 women, did through 1991. The students were rated on
their personality traits and behaviors, along lines similar to the “Big
Five” personality traits: openness to experience, conscientiousness,
extraversion, agreeableness and neuroticism.
One striking result is how much the trait of conscientiousness matters. Men who measure as one standard deviation higher
on conscientiousness earn on average an extra $567,000 over their
lifetimes, or 16.7 percent of average lifetime earnings.
Measuring as extroverted, again by one standard deviation higher than
average, is worth almost as much, $490,100. These returns tend to rise
the most for the most highly educated of the men.
For women, the magnitude of these effects is smaller…
It may surprise you to learn that more “agreeable” men earn
significantly less. Being one standard deviation higher on agreeableness
reduces lifetime earnings by about 8 percent, or $267,600.

There is much more at the link, and no I do not confuse causality
with correlation.  See also my remarks on how this data set produces
some results at variance with the signaling theory of education.  Here
is the original study.”
