Definition

The heuristics-and-biases thread maps where fast judgment shortcuts help — and where they systematically skew probability, memory, and confidence.

Origin

Daniel Kahneman and Amos Tversky showed that under uncertainty people use heuristics (availability, representativeness, anchoring) that produce predictable errors relative to normative logic. The 1982 edited volume Judgment Under Uncertainty collected the primary papers; Thinking, Fast and Slow (2011) narrated the program for operators. Gigerenzer’s ecological rationality line offers a deliberate counterpoint: simple rules can outperform complex models in sparse, structured environments.

Mechanism

The bias program is foundational for decision hygiene — not a claim that humans are irrational in every domain. Replication debates and domain scope matter: laboratory judgment tasks do not map one-to-one onto every coaching conversation. Use the lineage to teach when to slow the question (Quality of Questions) and when a simple rule (Heuristic) is ecologically smart. Pair Kahneman’s narrative with Gigerenzer when members confuse “bias awareness” with “always add complexity.”

Applications

  • When teams repeat the same forecast error — open the anthology spine, not only the popular book.
  • When a one treats every shortcut as stupidity — add Gigerenzer’s ecological counterweight.
  • Chronological trail: Judgment Under Uncertainty (1982) → Simple Heuristics (1999) → Thinking, Fast and Slow (2011).
