What part of my evidence do you consider worse? The evidence of actual women who have avoided conferences because of harassment? Or you mean a paper that actually gathers statistics that demonstrate that women are more likely to leave male-dominated fields than ones which have a more even gender distribution?

And half of what I was complaining about was that you linked me to a 4 and a half hour long video series, which from a brief glance at the first video, appeared to be some guy just trying to get some Norwegian academics to claim that both sexes are exactly equal, and then catch them out on that. I had no idea where to look in those videos for evidence of the actual claim that you made, that once a profession is no longer taboo for women to join, they have less desire to do so. Could you please tell me where in those videos to find that evidence? Or, since he doesn't seem to be doing any original research himself, just interviewing academics on a variety of topics, can you point out the research that he summarizes that contains this information?

> When you observe an uneven sex ratio in a particular field, you need to form a hypothesis to explain that ratio, and then test it. You can't just jump to "it is sexism" as a conclusion.

The paper I linked to did test certain hypotheses about why it happened, and one of them that it found evidence for is that the larger ratio of men in the industry leads to more women leaving; which forms a self-perpetuating cycle.

You're right, this doesn't directly address sexism, but it does provide evidence for why there's an uneven ratio, and why it continues to be that way, even if more women enter the profession than before.

> But since you skipped the testing the hypothesis step and went straight to a conclusion, you find this offensive and unimaginable.

But it's not just the uneven ratio that we're concerned about. As I said many times, there may be multiple reasons for it; perhaps harassment is only a small portion of the reason. It is obviously a part of the reason; as I've pointed out, there is plenty of anecdotal evidence for that, of people who have been harassed out of the industry, or out of certain communities within it. But you're right, without a rigorous study, we don't know how much of an effect that is, versus other factors.

The "offensive" part is denying that there is any harassment, and denying that men should try to stop it. There is harassment. There is behavior that makes women feel uncomfortable. Rather than being defensive and claiming that people shouldn't jump to the conclusion that sexism isn't the reason why there are few women in the field, why don't we try to not act sexist, stop sexism when we see it, actively try to eliminate at least that problem? Perhaps it won't lead to a lot more women in the industry, as they are avoiding it for other reasons. That's OK; we're still at least working to fix the sexism problem.

Note that I'm not claiming that all, or even most, men in tech are sexist. I'm not claiming that there is a unique sexism problem in tech. What I'm saying is that there is sexism, that it does hurt real people, and so if you see it, you should do something about it.
