Narrow Framing (Kahneman & Tversky)

The tendency to make decisions in isolation rather than as part of a broader portfolio, leading to excessive risk aversion for individual decisions that would be perfectly reasonable in aggregate. The failure pattern: (1) a decision is presented as a standalone choice, (2) the decision-maker evaluates it on its own merits, (3) loss aversion dominates because a single loss looms large, (4) a positive-expected-value opportunity is rejected because the downside feels unacceptable in isolation, (5) over many such decisions, the aggregate result is systematic under-performance due to rejected good bets. Samuelson's colleague example: an economist who rejected a single $200-win/$100-lose coin flip but would accept 100 of them. Each individual bet feels risky; the aggregate is nearly risk-free with high expected value. Narrow framing explains why companies reject innovation projects that individually might fail but collectively would be highly profitable, and why individuals avoid career risks that in aggregate would produce better outcomes.

When to use it

When evaluating individual risks, investments, or career decisions. When loss aversion is preventing positive-expected-value action. When each individual opportunity seems too risky but you recognize that never taking risks is also costly. During investment or innovation portfolio decisions.

How it can help

Provides the specific reframe—from isolated decision to portfolio decision—that converts risk-averse paralysis into rational risk-taking. Interventions: (1) before evaluating any individual opportunity, place it in the context of all similar decisions you'll make: 'Over the next 10 years, I'll face 50 decisions like this—what policy should I adopt?' (2) Use the 'one of many' rule: if you would accept this bet if you could take it 100 times, you should probably accept it once. (3) Create organizational 'bet portfolios' where individual project failures are expected and budgeted for. (4) Ask 'What's the aggregate outcome of always saying no to opportunities like this?' The reframe from single-decision to decision-policy is the key cognitive shift.
