91 percent female

Maybe this explains the Great Resignation? Or part of it, anyway? Also, 7 other things worth your time.

I set out today to write about a mystery in psychology, only to realize there might be a clue toward solving an even bigger mystery.

But let’s back up: Something odd happened recently to an entire community of graduate psychology researchers, who suddenly noticed that women, but not men, were willing to participate in their online studies.

A psychology student from Cornell University named Sebastian Deri was the first to post about the situation on social media.

During the summer, he ran an online survey using one of the widely used industry platforms to get participants (more on these in a moment). About 300 people took his survey about “social comparisons and money,” but the demographics were heavily skewed toward women: 91 percent female, 7 percent male.
