CONCEPT
Attribute Substitution
Kahneman and Shane Frederick's term for
System 1's practice of answering an easier question when confronted with a hard one —
without the answerer noticing the substitution has occurred.
Attribute
substitution is the cognitive operation by which the mind, confronted with a difficult question it cannot readily answer, silently replaces it with an easier related question and answers that instead. Asked "how happy are you with your life?" — a question requiring integration across many domains — System 1 substitutes "how do I feel right now?" and delivers the current mood as though it were the comprehensive assessment. Asked "how much would you contribute to save the dolphins?" — a question requiring economic analysis — System 1 substitutes "how much do I care about dolphins?" and delivers emotional intensity as a financial answer. The substitution is seamless. There is no experiential marker that alerts the person to the switch. In AI collaboration, substitution operates bidirectionally: the machine often answers a question adjacent to the one asked, and the human evaluates the answer using substitution heuristics that make the mismatch invisible.
