Delusion

A thesis without falsification criteria. Sunk cost wearing conviction's clothes. No observable outcome would trigger an exit, which means the position cannot be wrong — it is faith, not analysis. Popper's test: a claim that explains every possible outcome is not a strong claim.

Psychology Conviction A thesis held with explicit falsification criteria — specific, observable conditions that, if triggered, would prove the thesis wrong. Articulable in plain language. Held in light rather than in defense: disconfirming evidence sharpens or kills the position, and both outcomes are wins. → Psychology Falsification Criterion A specific, observable condition that, if it occurred, would prove the trader's thesis wrong. Popper's test for whether a belief is conviction or faith. Before entry: write down 'I would exit this position if ___.' If the blank cannot be filled with something specific, the position is hope, not conviction. → Psychology Sunk Cost Fallacy Continuing to commit to a course of action because of resources already invested, rather than future expected value. In memecoins: holding a dying bag because 'I've already lost so much.' Sunk costs don't predict outcomes — they predict only that you've already paid. →
