On: We like impostor stories because we’re afraid we’r...

You are confusing expert being imposters and imposters being able to be experts. That's not the same thing. Most people couldn't do my jib without training, they are not expert in my field, yet I have never been trained to manage a team or a project, answering a customer, dealing with a crisis. Hell last I once coded a software to help with tuberculosis diagnosis and I had to look at the doctors in the eye like I was ready for it.

You have to pretend you know how to seduce, to deal with your daughter crying with no apparent reason, to pay taxes because that what adults do.

If you're not counting your past experiences as "training", then by your own definition, most people could do your job "without training".

The point is that if you were trained in your domain, you can't hold yourself up as an example of "an imposter who had to learn it all themselves" because some of it was given to you as "absolute" knowledge. That you weren't "trained" in some 'basic tasks' (and some people are - imagine the boy scouts, preparatory schools or the military) doesn't mean you had to "imposter" your way into learning everything else - you simply learned those "by osmosis". (Otherwise, we'd have thousands of different ways of accomplishing each of those basic tasks in use.)

Social interactions are informed by past interactions, in a sort of "telephone game" through time and society (which is why trends evolve and change). And we aren't trained how to do taxes because there's an entire industry devoted to profiting off them which lobbies to keep it feeling complex and against just having the IRS send you a form to sign or dispute.

For most of the thing you have to do in your life that matters, you have no past experiences about it. You are not competent before you accumulate a lot if experience in it, which may or may not arrive, and late in life. But society assumes you know from the very first time.
