There is a strong belief that women are more generous, and care more about equality, than men. Also, many people believe that women tend to be underconfident. None of these beliefs are true, two recent papers find. One paper —nicely titled "Men are from Mars, and Women Too"— focuses on self-confidence. The paper starts by surveying hundreds of experts, finding that 77% of them think that women are underconfident whereas men are overconfident. Next they do a comprehensive survey of all experimental tests of self-confidence that have been published in the past twenty years. The key result: 72% of all studies find that *both* women and men are overconfident. Only 18% of published studies support the commonly held view. The other paper considers social preferences. "Using data from 15 studies and 8,979 individuals" the paper finds "that women are believed to be more generous and more equality-oriented than men. [...] Yet this believed gender gap is largely inaccurate." The authors "find little to no evidence for gender differences in behavior or attitudes relating to social preferences". Hence, women and men are much more similar than commonly thought. Sure, people differ in their social preferences and self-confidence, and actually differences can be quite substantially. But gender is not predictive of such differences. Why is this important to know? Why is it important to correct these misperceptions about women and men? One reason is that misperceptions may affect selection and sorting in the labor market, in politics, and in society at large, resulting in a misallocation of talents and traits. For instance, if people think that to be a good leader one needs to have sufficient self-confidence, they may be biased against women, as they mistakenly believe that women tend to be underconfident. Likewise, people may be biased against men when selecting for positions that require generosity and care, mistakenly thinking that these qualities are mainly or only present among women.
