I’ve been thinking a lot about curiosity lately. Specifically, about curiosity in the sense of the proverb curiosity killed the cat: a potentially self-destructive pursuit of knowledge for its own sake that leads to unnecessary risk-taking. In humans such risk-taking often threatens not just the individual or even family/immediate group, but the whole species. Some people just have to go around figuring out new ways to blow things up, often with the noblest of intentions.
At a selfish gene level, the trait seems complicated, but not mysterious. The question that really interests me is this: how do our selfish genes fool us into being curious creatures, who sometimes get themselves killed, to teach our gene pools more about the environment? Altruism, a similar potentially self-destructive trait at the individual level, manifests subjectively as love (especially for kin), a sense of belonging to one’s community, and a capacity for attachment to some notion of greater purpose. What might be the analogous subjective experience for curiosity?
Curiosity does not seem to be a fundamental drive, unlike what I am told are the three basic biological drives (seeking pleasure, avoiding pain and conserving energy), so it is probably derived. Curiosity requires a certain energy surplus, since its visible signature is a restless dissipation of energy, but it does not seem directly motivated by energy conservation concerns. So is it derived from pleasure-seeking or pain-avoidance or some mix of the two? Does that make a difference?
I think it does, and I think the answer is that curiosity is primarily derived from pleasure seeking, not pain aversion. This has certain observable consequences.
