You know what? That "no emotions" bit is from a discussion I read regarding sociopaths (not from this forum, I think it was on a World of Warcraft forum). I haven't seen any NT claim to have and enjoy some bastardized pseudo-sociopathy.
I think the "INTP and Sociopath" thread from this forum and the discussion which I mentioned from the WoW forum crossed paths and mixed in my head and then I tossed it into one of my posts. I'll edit that out, it's false.
But besides that...I can't speak for the entire INTP population, but I know I have emotions. I'm pretty sure that any human with a healthy brain will have some kind of emotions, both weak and strong. It's just a matter of trusting them, or using them, or following through with the impulses they create, or whatever etc etc.
