  Kane and Mertz's 2012 AMS Notices article "Debunking Myths about Gender and
Mathematics Performance" claims to have debunked the greater male variability
hypothesis with respect to mathematics abilities. The logical and statistical
arguments supporting their claim, however, which are being widely cited in the
scientific literature, contain fundamental errors. The methodology is
critically flawed, the main logical premise is false, and the article omits
reference to numerous published scientific research articles that contradict
its findings. Most critically, Kane and Mertz's final conclusion that their
data are inconsistent with the greater male variability hypothesis is wrong.
The goal of the present note is to correct the scientific record with respect
to those claims. Most importantly, by publicizing these errors, the Notices
will reduce the chance of similar future errors being repeated.
