I'm not sure. My niece was on an all-women STEM floor of her college dormitory. After 2 semesters, she was the only woman still in STEM. The rest had all convinced each other to do something easier. Not the success story you might imagine.

I have no idea either way, but this amount of data probably shouldn't sway predictions too much.

Anecdotes aren't data for sure, but they can be helpful to build a mental model or explain a hypothesis. The argument would be much less clear if JoeAltmaier had simply said "I'm not sure" with no elaboration.
