Oh gosh, I'm a grad student in social psych, and my field is basically built on these. I find that these tend to make Americans uncomfortable.

The vast majority of people only help others for selfish reasons, such as enhancing social reputation, or expecting a return on investments. social exchange theory applied to altruism

Punishing people more tends to cause them to become more amoral. People in the U.S. consistently deny it, because it violates their sense of 'what is just'. cognitive dissonance applied to insufficient punishment

There's mounting evidence that feminism (as a scientific theory), the idea that gender differences are mainly the result of male dominance, is dying. Consider, women's rights movements are one of the few peaceful movements that have been overwhelmingly successful (cf. African-American civil rights involved intense riots). Women's rights have almost all been granted by male power figures/institutions. Men frequently support feminism. Ironically, feminism is a linguistically sexist word (as it has the root, "fem"), but women have managed to successfully define it as "gender egalitarianism". (For comparison, the definition of "masulinism" is "male control"). Moreover, feminism is not gender equal in its endorsement of issues. It used to be that women wanted education; now they represent 60% of college students. Alas, attention is diverted to other resources that women can take from men, instead of there being concern over why men aren't going to school (which, you'd think educating men would increase awareness of women's rights). All of this seems to imply the opposite of feminism--men aren't so dominant after all. In fact, it seems that men are rather weak in the face of women, as they readily hand over power, rights, resources, and even accept distorted language, all at the behest of women. To be clear, I'm not saying women didn't have to work or suffer for these things, or that the genders are treated equally, just that male dominance seems to be a (scientifically) poor explanation for gender differences.

People who are more individualistic tend to have shorter, less satisfying relationships, because they put themselves before the relationship and are more than willing to back out. This conflicts with a lot of relationship advice you hear in the U.S.
