“[I]t’s usually men who won’t shut up,” he tweeted, pointing to a study from Cornell University’s Johnson School of Business showing men tend to talk more in meetings, even when the majority of people in the room are women. Men also interrupt more. Gaining power seems to be correlated with talking more in meetings—but only for men, not for women. Another study shows that men not only speak more frequently during meetings but also speak longer.

Globally, women hold just 16.9% of board seats, according to a 2020 Deloitte report. The numbers are more dismal for women of color. Meanwhile, women who get to the top are more likely to be assessed on their voices and personality than men—ironic given that a study of 155,000 company conference calls over the past 19 years found that it was men who spoke 92% of the time.

Perhaps Mori simply hasn’t had a large enough sample size to accurately assess situations involving women on boards. According to a 2020 World Economic Forum report, Japan’s gender gap is the largest among all advanced economies in the world.
