As a man who struggles with low confidence and self-esteem, I hate the way women are given special attention over this stuff. I frequently don't apply for jobs I see that I could probably do, for all of the reasons listed in the article. A couple of times I have even pulled out after a successful first round interview due to anxiety about continuing. This is an example of how the "women in tech" movement alienates me…
I'm sorry for your situation but articles like these are looking at trends across groups. They're not meant to insinuate that every man is in a better position than every woman. The article talks about surveying 1,000+ men and women. Undoubtedly, some of the men in that sample had less confidence than some of the women. It doesn't make it invalid to analyze statistics across the group overall.
I think calls for greater clarity and attention to detail when doing data analysis are well-considered and we should be _deeply suspect_ of claims made based on statistical aggregates, and particularly the mean average which is one of the most distorting and lossy aggregates there is.
