Every mental model you carry was built during a previous version of you. Philosopher of science Imre Lakatos noticed something troubling about how scientists actually work: when evidence conflicts with a core theory, they don't abandon it — they construct auxiliary hypotheses to protect it. The inner belt of the theory stays untouched while the outer layers absorb all the damage. The same architecture runs inside your head. The mental models that have served you longest are not the most scrutinized; they're the most defended. They sit at the center, quietly shaping which features seem worth building, which user signals seem like noise, and which version of yourself you consider 'realistic.' The 14th-century Islamic historian Ibn Khaldun called this 'asabiyyah — the binding loyalty that holds a group together — but he also warned it was precisely the thing that made civilizations incapable of recognizing their own decline. The same solidarity that coheres a worldview also immunizes it. The move isn't to distrust your models wholesale. It's to locate the auxiliary hypotheses — the small rationalizations you've bolted on recently to make your older beliefs still work — and recognize those patches as the address where the actual revision needs to happen.

What's the most recent explanation you gave yourself for why something didn't work — and does it protect a belief you've held for more than five years?
