Thus, contrary to common belief among academics and practitioners, skewed returns do not allow a rejection of mean-variance analysis. Our work differs from Chamberlain's [Chamberlain G (1983) A characterization of the distributions that imply mean-variance utility functions. J. Econom. ...

We propose that this occurs because, during periods of destigmatization, conscious prejudice has diminished but nonconscious prejudice remains, so people correct for their explicit biases toward indi...
