Core Idea

Reliability of case evidence asks how much weight a single case — one customer story, one founder's success path, one market data point — should carry in forming beliefs. Individual cases are vivid, memorable, and persuasive, but they carry enormous hidden variance. A single successful customer doesn't prove product-market fit. A single founder's strategy doesn't generalize to all companies. The model warns that the human brain overweights narrative case evidence relative to its actual informational value, especially when the case is dramatic or emotionally resonant. Reliable conclusions require multiple independent observations, not compelling anecdotes. The question isn't whether the case is true — it's whether it's representative.
