One idea in order to get better at anything: mimic/copy successful people.
I think this should be at least a little bit surprising, the fact that our mimicry abilities can extend to latent space like this. Some combination of largely unconscious mental processes gives us the ability to simulate the thinking of others, even though we have no direct ability to observe it. Think of how quickly you can tell, just from an unusual text message, that a friend is unhappy. Even if we have only a small sample of observations of someone whose instincts we trust deeply, we probably have enough material to ask, “Does it seem like they would do this?” Trying to explicitly reason about the basis of ethical action is complicated.
