If I had to teach this in one paragraph, I would start here: base rates protect you from falling in love with a vivid but statistically weak story. Core idea: Narratives are powerful because they are memorable. Base rates are powerful because they stop you from overpaying for what is memorable. Why it matters: That matters in markets because rare success stories get far more airtime than ordinary failure paths. In real life: Before treating a turnaround as obvious, ask how often similar balance-sheet situations actually stabilize without dilution or restructuring. Common slip: The classic mistake is replacing sample-wide evidence with one persuasive anecdote. Try this: Explain in one sentence what problem this idea solves and what problem it does not solve. That is the kind of small conceptual habit that compounds into better decisions over time.
