I beg you to differ

[x_equals_speed]

I just came across a paper discussing how similar friends are in terms of their opinions. Essentially it concluded that friends are more similar to each other than they are to random strangers, but are less similar to each other than they think they are. Apparently the reason for this is that when you infer your friends opinions discussions you have with them are part of the process, you also use a lot of sterotypes and project your own opinions to fill in any gaps (or even over their real opinions).

I'm now curious about where I've been doing this with my friends. With what frequency do I think you hold an opinion that you'd disagree with? I can think of no proper way to test this (or more accurately I can, but I have enough work of that type on) so I'm just going to throw it open. What do you believe that I might not know? What do you think I believe that I might not?

Gimme a few on each point and I'll try to respond in kind.
