That's an interesting supposition but I'm not necessarily sure it's true. If you consider the number of women graduating with computer science degrees between then and now[1], the trend is the still there: growth until the mid 80s and then reversal. If the trend were merely explained by the fact that tech jobs have transitioned from "secretarial" jobs to engineering roles, why is it also present in the ratio of women studying actual computer science in college?
> What about other industries with even more skewed sex ratios but fewer or no high-profile articles about sexual harassment, what's the cause in those industries?
Since my point is that the gender ratio itself is a red herring, I'm not sure what the purpose would be in speculating about its cause in other industries.
> Has anyone put to an analysis that these sort of events occur more frequently in the tech industry, rather than the tech industry is high profile and thus these events get more attention?
That's your argument? That the level of sexual harassment in the tech industry is at a "normal" level relative to other industries and is simply over-reported?
It sounds like you're bending over backwards trying to justify the status quo here. But okay, for the sake of argument, let's assume it is simply over-reported. Does that make it any less problematic? Should we simply accept the situation as "well, that's just the way things are", instead of actively trying to improve it?
