> we can apply the rule, "-A cannot follow from A", etc. regardless of the A

You can't think of any domains where we are unable to apply this rule? I feel like I'm surrounded by people claiming "A, therefore -A!!"

And if I'm one of them, and this were a reasoning dead-zone for me, I wouldn't be able to tell!

That's an abductive failure to recognise that something is A, and something else is not-A

I dont see cases where people recognise the contradiction and then perform it.

		People who know alcohol is bad for them and don't want to keep being drunks but keep drinking, people who believe phones are bad for their kids but still buy them, people who understand AI will significantly degrade the environment if it becomes ubiquitous but still work to help it become ubiquitous... Mathematicians who publish proofs that are later proven inconsistent! I suspect we have fundamentally different views of how humans work. I see our behavior and beliefs as _mostly_ irrational, with only a few "reasoning live-zones" where, with great effort, we can achieve logical thought.

		How can you know? One could argue that the entire phenomenon of cognitive dissonance is "people (internally) recognize the contradiction and then perform it"
