Narrow Framing

The cognitive error of evaluating decisions in isolation rather than as part of a broader portfolio—treating each choice as if it exists independently rather than as one of many decisions you'll make. A single bet with 50% chance of losing $100 feels risky in isolation; as one of 100 such bets, it's nearly risk-free. Narrow framing produces excessive risk aversion for individual decisions and excessive emotional reaction to individual outcomes. Investors who evaluate each trade independently make worse portfolio decisions than those who evaluate aggregate performance. Narrow framing turns rational portfolio strategies into seemingly irrational individual decisions.

When to use it

When individual decisions feel paralyzing despite having a sound overall strategy; when loss aversion is preventing rational risk-taking; when evaluating performance and tempted to judge individual outcomes rather than decision quality; when building a portfolio approach to investments, experiments, or strategic bets.

How it can help

When facing any decision, ask: 'Am I evaluating this in isolation or as part of my larger portfolio of decisions?' A startup investment that seems terrifyingly risky as a standalone bet may be perfectly rational as one of ten investments. A feature that might fail is reasonable as one of twenty experiments. The aggregation mindset: over the course of a year, you'll make hundreds of decisions—the question isn't whether any single decision is guaranteed, but whether your decision-making PROCESS produces good aggregate outcomes. This dramatically reduces anxiety around individual choices.
