Epistemic Trespassing
Being an expert in one thing doesn't license you to broadcast hot takes in another.

Know what it actually is
Epistemic trespassing is judging matters outside your field of expertise as if you were qualified. Coined by philosopher Nathan Ballantyne in his 2019 paper 'Epistemic Trespassing' (the journal Mind). The Nobel laureate physicist who lectures you on nutrition, the celebrity doctor opining on economics, the engineer who decides he's cracked epidemiology. Expertise in one domain does not transfer to another, but your confidence doesn't get the memo.
Understand why your brain does it
Two errors stack. First, you misjudge the boundaries of a field, assuming your toolkit applies where it doesn't. Second, you misjudge your own competence inside it. This is propped up by the Dunning-Kruger effect (David Dunning + Justin Kruger, 1999): the less you know about a domain, the less equipped you are to even see how much you're missing. Real experts know where the hard parts are. Trespassers don't know there are hard parts.
