Treat judgment difficulty as a signal to slow down
When a question feels easy to answer, that ease may mean your brain swapped it for a simpler one.
Why it works
Cognitive fluency — the ease with which a mental process runs — is used as a proxy for correctness. Questions that feel easy to answer receive less scrutiny. But attribute substitution makes hard questions feel easy by replacing them: the hard target question is silently dropped and the easy heuristic question runs instead. Using perceived ease as a flag for substitution — rather than as a confirmation of insight — reverses the usual heuristic.
How to do it
- When a difficult judgment arrives with surprising ease, pause and ask: "Is this genuinely simple, or did I simplify it?"
- Write out the target question in its full complexity.
- If the question, stated fully, doesn’t match the answer you gave, you may have substituted.
Evidence
Cognitive fluency research shows that ease of processing is used as a cue for truth, familiarity, and validity. This effect is well documented but is a double-edged sword — ease can also signal genuine expertise. (observational)
Expert intuition also produces fast, easy, accurate answers. Ease is a flag for scrutiny, not proof of substitution — context matters.

Common mistake
Applying this check to all fast judgments and second-guessing genuine expertise — the check is most valuable for high-stakes, novel, or socially charged decisions.

More practices for Attribute Substitution: When Your Brain Answers a Different Question
- Name the question your brain is actually answering
When you reach a quick judgment, ask: "What question did I actually just answer?"
- Check whether your judgment is tracking affect, not the target attribute
When a decision "just feels right," ask whether the feeling is about the actual question or about your current emotional state.
- Interrogate whether similarity is doing the work
When assessing probability or quality, ask whether you’re really judging similarity to a prototype.
- Decompose the target attribute into components before judging
Break a hard question into its component parts and answer each one directly, rather than letting a heuristic answer the whole.
- Label the easier attribute you’re being tempted to use
Name the shortcut attribute explicitly ("I’m using attractiveness as a proxy for competence") to reduce its pull.
- State your estimate before encountering vivid case information
Lock in a prior probability estimate before reading a compelling story or meeting a specific candidate.
