Conservatism Bias

New evidence arrives — strong, clear, unwelcome. Watch what people do: they nod, they concede politely, and they change their minds by about a quarter of what the evidence demands.

The mind treats its current beliefs like a house it has already paid for. Renovation is expensive; so it patches. Each new fact is squeezed into the old structure, and only when the walls actually crack does rebuilding begin.

This is why opinions lag decades behind data, in science as in kitchens. The old view does not lose the argument. It simply outlives its opponents.

The corrective habit: when evidence surprises you, do not ask "can I keep my old view?" Ask "if I had never held any view, what would this evidence make me believe?" The difference between those two answers is the tax your house is charging you. Pay attention to the size of it.
