For further reading this is called the Variability hypothesis, that male ability has higher variance (but not necessarily a higher mean) than female ability: https://en.m.wikipedia.org/wiki/Variability_hypothesis

(Not making a judgment as to whether I believe this is true or not)

Did le wik rename this from Greater Male Variability hypothesis when I wasn't looking?!

Check the article's revision history; it's public. It was simply called "variability hypothesis" from the article's creation in 2007, and in September 2018 the additional name was added.
