Some humans who are not trained that curiosity produces beneficial outcomes are often not all that curious. It is difficult to know what is truly innate vs. the result of conditioning. It is also difficult to know what is the result of an absence of opposing conditioning. If I was raised in a poor area with high crime and little economic opportunity, my conditioning would be quite different. How would that have changed my behavior? Could curiosity get me in more trouble than it's worth? Could I observe that and adjust my own behavior as a result?
We are all, to some extent, a product of our environment (training data). I wasn't raised in that type of area, but does that mean my own intellectual curiosity is more innate? Or does it mean it is less innate? I could argue that both ways.
