Apply David Deutsch's "hard-to-vary explanation" test to a theory, hypothesis, business strategy, scientific claim, or any explanatory story. Use when the user is evaluating a theory, debating an interpretation, choosing between competing hypotheses, or trying to detect bullshit. Sourced from "The Beginning of Infinity" by David Deutsch, Chapter 1.

From the source SKILL.md
