But really. I am generally considered to be both pretty and smart. When I have first entered various nerdy groups, I have had people tell me that their initial impression of me was that I was a delusional poser (actually words varying) and didn't belong. But then they quite consistently have said they changed their minds after I started talking. Yes, the stereotype/stigmatism/whatever is there. People do form perhaps harmful initial impressions. But the impressions are often easy enough to change and I have never once (that I know of) been crippled socially by it.
