Sharpening Abductive Reasoning

Generate at least three explanations before settling on one. Quantity of hypotheses improves the quality of your choice, because it forces you past the obvious first answer.

Weigh probability first. Ask how often each explanation actually occurs, and give the everyday causes more starting weight than the dramatic ones.

Update in proportion to the evidence. A small clue should nudge your confidence; a decisive test result should move it sharply. Match the size of the shift to the strength of what you just learned.
