One striking revelation is that education, specifically being highly-educated, plays a major role:

“Young men with secondary-level education were more likely to sexually harass women than their older, less-educated peers.”

“Around half the men they surveyed, for example, said they felt stressed, depressed or ashamed to face their families. Perhaps harassing women is a way to assert their power,” suggests Gary Barker, Promundo CEO and co-author of the report.

“These young men ‘have high aspirations for themselves and aren’t able to meet them,’ he says. ‘So they [harass women] to put them in their place. They feel like the world owes them.'”
