I'm no fan of sloppiness, either. But to me, this isn't a sign of sloppiness. It's a sign of being human.
...it had been paleontology or geology that had been 'rocked' by this case. But I'm struggling to understand why such a story is relevant to a science/technology news website?
Because one of the big questions about the science and technology fields are why women are so under-represented.
Stories like this contain at least part of the answer.
Perhaps, but I suspect that's a significant oversimplification. Gender interests in various topics are generally "dialed in" by mid-high-school age or before -- college major gender preferences reflect high school preferences. I strongly suspect high schoolers aren't choosing topics of interests based upon expectations of future harassment in related careers.
A much more viable theory revolves around "caste effects" -- we tend to internalize the perceived characteristics of groups with which we identify. This effect has been posited as an explanation for disparities in IQ scores that break down along socially-identified racial groups (even when the underlying genetics and socio-economics are much more complicated). In the context of this topic, males or females see what they think men or women are "like" and what they "do", and tend to develop interests accordingly.
As for harassment and the sciences: Obviously, it's a problem for those already in fields where (most likely) one gender or the other is significantly under-represented, and it could tend to reinforce such under-representation. But I think it's more a symptom than a cause.
The sooner you fall behind, the more time you have to catch up.
