The Affect Heuristic in Decisions
Use an emotional reaction as a clue to a valued consequence, then verify the belief beneath it with the same standard used for both options.
Emotion can carry experience
A rapid sense of danger may reflect learned pattern recognition. High-stakes signals still deserve a pause and specific verification rather than dismissal or blind obedience.
Feelings compress several judgments
An option that feels exciting can appear more beneficial and less risky at the same time. An option that feels unpleasant can receive the reverse treatment. The reaction may reveal values, but it should not silently become evidence about cost, safety, or performance.
Translate feeling into a test
- Name the exact reaction.
- Ask what expected consequence creates it.
- Classify that belief as fact, estimate, or preference.
- Verify factual claims and preserve the preference separately.
Example: excitement about a new role
A job feels energizing because it appears to offer autonomy. The candidate checks reporting lines, decision rights, and examples from future teammates. The feeling identifies autonomy as important; interviews test whether the role supplies it.
The decision rule
What to record before acting
Let emotion identify what matters, but do not let it certify a factual claim without evidence.
Apply the rule in context with separate preference from evidence. Keep the evidence and assumptions with the decision so an outcome review can distinguish reasoning from luck.
