Me too. I've even done it before:

I have a facebook friend who writes thoughtfully, seems reasonably clever and cares about deep questions. He is a speaking-in-tongues, deeply religious, Prosperity, Charismatic, Word of Faith, Christian. A few of his interests and landmark-experiences match my own.

I was excited to talk to him because I thought he would be able to teach me something about religious people that 'normal people' couldn't.

I also thought the skeleton of his personality was similar enough to mine that he might have made an 'interesting mistake'. Due to the similarities between us, I wondered if I could also be susceptible to whatever 'wrong turn' his thinking took. I wanted to identify and analyze that 'interesting mistake', so I wouldn't make it, and because I expected it to be weird and interesting.

It turned out his mistake wasn't interesting and I was disappointed.
