When auxiliary hypotheses are adjusted after prediction failure, require the adjustment to generate new testable predictions rather than merely explain away the original failure.
Why This Is a Principle
Derives from Hindsight Bias and Calibration Necessity (memory reconstruction and hindsight bias) and Belief Perseverance Against Contradictory Evidence (belief perseverance). This principle operationalizes Lakatos's distinction between progressive and degenerating research programmes at the personal level. It's prescriptive (tells you what to demand from schema revisions), derived (builds on cognitive biases), and actionable.
