Here's one of the few ENTPs piping up. I laughed my way through the article too - it's strange to see past experiences so clearly outlined. And I don't know if this was a gender thing too, but I remember sitting in a class, noticing that no one else was raising his/her hand, and thinking "hmmm. i thought this was an easy question. If nobody knows it, i must be wrong. I won't raise my hand either..." This happened all the way through law school! I guess it took having a smart kid to realize that I was one too.
