• One story has completely sold me on something and I’m about to act on it
• Someone fits the picture of a type so perfectly that I just assume that’s what they are

• I always build my whole story first

Practices that may help

1. Base-Rate Neglect: Why We Ignore the Odds
   Base-rate neglect is the tendency to underweight or ignore prior probabilities (how often things happen in general) when vivid, specific information is available. Identified by Kahneman and Tversky, it is one of the most robustly replicated biases in judgment research, and it leads to systematic overconfidence in predictions about specific cases. Correcting it requires actively looking up or estimating base rates before evaluating individual information.
2. Ask the base rate before evaluating the specific case
   Before judging any individual instance, first establish how often this kind of thing happens in general.

3. Look up base rates before forming a resemblance judgment
   Before deciding "this looks like X," ask how common X actually is in the relevant population.

4. Deliberately invoke the outside view for important decisions
   For any high-stakes prediction, force yourself to start with how things typically go, not how your situation feels.

5. Update beliefs by degrees, not wholesale
   Treat new information as evidence that shifts probabilities, not as proof that changes everything.

6. The Availability Heuristic: Why Memorable Feels Probable
   The availability heuristic is the mental shortcut of judging how common or likely something is by how easily examples come to mind. Tversky and Kahneman identified it in 1973. It is adaptive in many everyday situations but systematically misfires for dramatic, recent, or emotionally vivid events — causing consistent over- and underestimation of real-world probabilities.
7. Lead with statistics, then interpret with narrative — not the reverse
   Use the base rate as your anchor, then adjust for your specific situation — not the other way around.

8. Check the actual base rate before trusting your intuitive estimate
   When an event feels common or rare, look up how often it actually happens.

9. Expect regression to the mean in extreme outcomes
   Unusually good or bad performance tends to be followed by more average performance — not because of what you did.

10. Actively seek disconfirming cases
    When researching base rates, specifically look for cases where things went badly — failure cases are underrepresented in natural memory.
