It all goes back to the fallibility of the first person point of view.

It’s a lifelong struggle for everyone. Our wants are much clearer to us than everyone else’s wants, because we are the ones who have our wants, while it’s everyone else who has those other, much less vivid and urgent wants.

And by the same token we think much more highly of ourselves than of everyone else, because we know ourselves from the inside, while everyone else is…well, everyone else.

We learn about this struggle as we get older, and we try to correct for the personal point of view, when we feel like it, and when we know we’ll be arrested if we don’t.

It’s a survival mechanism though, so we hesitate to over-correct. We can perhaps justify selfishness as being good for the species if not necessarily for the less assertive members of the species.

At any rate, one of the things we spend a lifetime learning and re-learning and reminding ourselves of is the fallibility of the personal pov.

Except when we don’t. Except when we come up with a weird new ideology that claims the personal pov nullifies everyone else’s pov because it’s personal. Epistemology turned inside out and wearing a bright orange wig.

The fact that all human beings apart from one can see that Person1 is male is entirely beside the point when Person 1 insists he is not male.

Result: more and more people think like infants, and nobody knows how to do anything, and humans go extinct.
