My first idea is to ask your brother for advice - he probably has some friends, and if he's good at correcting you in a way you can appreciate, he might be able to figure out what's wrong on your end and help you fix it.

Interesting. I know him well enough to know that he would dislike the same people who I'm currently disliking, but I think that for whatever reason he might know more about how to find interesting and intelligent people.

As of now, he has more friends than me. We were roughly equal during high school. His social role when he's in groups is generally to be slightly quieter than average, but then to fire off witty and sarcastic one-liners at certain times. My social role is nothing, I find it hard to function when I'm not problem-solving or analyzing. I didn't really have friends in high school so much as people who weren't actively rude to me and who valued my input, to be honest. I should probably figure out a gimmick and stick with it, like what my brother does, the problem is that this feels inauthentic to me. His comes to him naturally whereas I don't really seem to have any inherent social role.

Can you be more specific? Different subcultures use different social norms. There might be one compatible with you.

Drinking and making jokes about sex. Self congratulatory behavior and bravado. Inauthenticity in general.

I'm uncertain whether everyone is really like this, or whether they're just signaling that because they're insecure college freshmen boys and that's stereotypical behavior and they're scared of being an outsider. I think it's probably some of both insofar as they're internalizing these norms because they find the internalization of these norms advantageous. I hope it will calm down soon if it is primarily signaling, but I don't think that will actually happen because the underlying factors will still exist and will actually be intensified by this internalization. I expect it will wind down once there's an external incentive to be responsible or at least to be perceived as responsible, but that will probably take at least a couple years.

This college is too small for legitimate subcultures to exist. I thought that small class sizes would be a benefit, but I never considered that it would caused increased pressure for conformity, which it seems to have done. That sucks.

I think you're underestimating human heterogeneity. The fix for this is to meet many different people, not engage in the kind of behavior you hate, and not bother hanging out with anyone who is put off after you learn that they were put off. You are not overwhelmingly likely to run out of people unless you live in the middle of nowhere. (Do you?)

I feel as though I'm trapped on my college campus. I live in an unfamiliar city of 150,000 people. I'm unsure where else I should go to meet and interact with people my age. I don't really enjoy anything except playing games and intellectual conversations; I should broaden my areas of interest, I suppose. I don't know how to get involved in off-campus activities though, or how to find out about them, or whether they exist for people my age. I also tend to be very static and stagnant; one of my major flaws is that I'm reluctant to change habits. This is another part of the reason why I feel trapped.

I don't really know how to meet new people without broadcasting desperation, either.
