"As an example, after university I discovered that when I'd been struggling alone to do my assignments and assuming all the guys were just finding it easy, all the guys were going round to each other's rooms, hanging out together, discussing work and looking at each other's code. They didn't think to invite me, possibly out of fear that I'd misinterpret it as a date or that I'd ruin the boys' club atmosphere, and I rarely asked them about work for fear of looking like I wasn't up to their level." - this x1000. It doesn't help when you're attending a super competitive CS program with a bunch of people who seem (or give the appearance of) knowing everything. I'm not saying they really could have done anything about it, or it's anyone's fault I felt excluded. In fact, it was entirely my fault I did all my group assignments alone; had I overcome my introversion, I have no doubt I would have gotten friendly responses. However, I think CS is going to be attractive for a higher proportion of introverted people than not. How do we make those environments friendlier to sensitive outsiders like this? It's not an easy problem to solve.
