Rather than adjusting facts to support the theory, he changes the theory to support the facts.

The search for truth is not achieved by replacing incorrect theories with correct ones; it's done by replacing incorrect theories with new ones that are more subtly wrong.

[Aurelius]

Theories shouldn't be judged in a two-valued system of "correct" and "incorrect", but on a continuous, opened-ended scale proceeding from worse to better. The "complete, perfect theory" being an unattainable end. And maybe a one-dimensional scale is inadequate.
