Do you think the initial sex disparity on OB/LW was mostly due to those communities being sexist from the start, or a selection effect caused by the subject matter, or something else?
Arguably, Overcoming Bias is (or was) an "economics blog" and men think more like economists.
From the Journal of Law and Economics:
The positive economic beliefs of economists and the general public systematically differ. What factors make non-economists think more like economists? Using the Survey of Americans and Economists on the Economy, this paper shows people think more like economists: if they are well-educated; if they are male; if their real income rose over the last five years; if they expect their real income to rise over the next five years; or if they have high degrees of job security. However, neither high income nor ideological conservatism have this effect. My findings for education, gender, and income have close parallels in political science: on tests of objective political knowledge, the better-educated and males score higher, controlling for numerous other variables, and the independent effect of income is minor.
Have you ever convinced a religious person to become atheistic? How did you do this? How long did it take? Were the people in some sort of life crisis, or were they just living along?
This is probably a quite difficult task of persuasion. So stories how people were successful at it could be very interesting to improve ones' persuasion abilities.
Relatedly, it might be interesting to know what religious groups have gathered on techniques to convert people to their religion - are there some manuals/techniques floating around?
