Good Explanations Are Hard to Vary

A good explanation can not be modified or molded to fit when new information contradicts it. It predicts situations that are both known and unknown. The domain of it’s meaning and applicability is not yours to specify.

Contrast that to a bad explanation—like a myth of winter caused by Persophone visiting Hades—which can be altered to fit new observations while resulting in the same prediction. It has no error correcting mechanisms and the myth can always be constrained or expanded to apply to any situation.
