Stage Thirteen - Evaluating Abductive Arguments

The four virtues

  • Consistency: theories that fit with what we currently believe are preferable to theories which do not.

  • Simplicity: theories that ask us to believe fewer new claims are preferable to those that ask us to believe more.

  • Testability: theories which can be tested are preferable to theories which cannot be.

  • Comprehensiveness: theories that explain more phenomena, and more new phenomena, are preferable to those that explain fewer.

Examples

  • In this video, I run through the simple example from the Stage 12 example video, and apply the four virtues of good theories to the proposed explanations.
