  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. Anchor on the base rate before adding inside-view details
    Start your forecast from the class median, then adjust — do not start from your narrative and adjust to the base rate.
    Reference Class Forecasting
  4. Always identify the denominator when evaluating risk or success
    When a number or story is striking, ask: "Out of how many total cases?"

  5. Actively seek disconfirming cases
    When researching base rates, specifically look for cases where things went badly — failure cases are underrepresented in natural memory.
    The Outside View
  6. 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.
