Challenges

So some of the time an intellectual challenge is to assimilate how similar we can be to other species. In other cases that challenge is to appreciate how, though human psychology 1 that of other species, we use the psychology in novel ways. We activate the classical psychology of vigilance while watching a scary movie. We active a stress 2 when thinking about morality. We secrete hormones related to nurturing and social bonding, but in response to an adorable baby Panda. And this 3 applies to aggression - we use the same muscle as does a male chimp attacking a sexual competitor, but we use them to harm someone because of their ideology.
