The “trick” you are referring to, requires you to care about other people in the first place.

As I recall, the section this came up was when they were coaching.

This does feel like another instance of how people have a deep instinctual grasp of social interactions, but a shallow ability to articulate the moving parts in detail.

I think the analogy was “everyone know how to use the flush, but they can’t explain the mechanisms behind it”
