Self-reporting bias would certainly have some effect, but not as much as brute similarity of worldviews regarding women, gender, sex, workplace etc. Like attracts like. Nothing fishy about that.
A lot of things are possible. Maybe Trump supporters are more likely to harass or maybe they surprisingly aren't; the most dangerously effective misogynist is one that adopts the language of political correctness but not the beliefs. This requires further study.
I think you should carefully reread that comment, that's not what I got out of it.
It's worth noting the social desirability bias here. It's likely the problem is actually much worse than the study indicates.
On the other hand, the NYT is not a scientific journal. Supposedly, they know what makes people interested in a topic. They want to start a public conversation, and while that's innocent and beneficial enough, they're starting the conversation on the wrong foot, and commentators like me end up having to talk about what I talked instead.
It would also be interesting if they brought up women-on-men harassment figures, if only to point that the numbers are so much lower, and other data that suggests that this might be indicative of cultural differences between how men and women in the West are raised (and not some innate male proclivity to harass that supposedly has to be socially repressed).
... or incredibly harmful.
This comment is not HN caliber and a lot of you know this and still upvoted. I sincerely hope some of you grow up or find a new community to trash in 2018.
