Every mental model you rely on was built from a past self's experience — which means it's quietly optimizing for problems you no longer have. Friedrich Nietzsche called this the danger of 'frozen valuations': the judgments we formed under pressure harden into rules we stop questioning. Combine that with what cognitive therapist Aaron Beck observed about 'schema maintenance' — the way we unconsciously filter incoming information to confirm our existing frameworks — and you get a troubling picture. Your mental models don't just describe reality; they actively recruit evidence to preserve themselves. The practical move: pick one model you use confidently and ask when you formed it. If the answer is 'years ago, under stress,' treat it as a hypothesis today, not a law.

Which mental model do you reach for fastest under pressure — and when did the experience that built it actually happen?
