I've already taken in intro philosophy class. Furthermore, I've been debating philosophical points with friends since I was a kid—and since I've grown up two of my good friends who I spent multiple years talking philosophy with were either presently in grad school for philosophy or had finished with it.

I see what you mean about doing philosophy in a group setting, but for what I'm interested in anyway, I'm not going to have a great time debating the above questions with an intro to philosophy class. A starting point for me to enjoy it would be that my interlocutors would need to be able to have some degree of understanding of the answers I gave above, what points might be in their favor, and what their limitations might be.

I can say no philosopher I've met personally would answer those questions like I did (though I think I've read some who would), so I'm still very curious to see why we choose different ways. But my guess is still just that they'd answer differently if they had more knowledge of cognitive science and other topics.
