Name the question your brain is actually answering
When you reach a quick judgment, ask: "What question did I actually just answer?"
Why it works
Substitution is invisible because the answer to the easy question feels like the answer to the hard one. The mechanism is that System 1 produces a confident answer without alerting System 2 that a swap occurred. Explicitly naming the target question ("what I should answer") and the heuristic question ("what I actually answered") forces the comparison into consciousness, where the mismatch becomes detectable.
How to do it
- After forming a quick judgment, write down the question you were supposed to answer.
- Then write down the question you probably answered (the easier, more intuitive version).
- Compare the two: if they’re different, you’ve caught a substitution.
Evidence
Kahneman and Frederick (2002) formalized attribute substitution as the mechanism underlying heuristics and biases. The model is analytically powerful and organizes a wide range of documented biases as instances of substitution. (mechanistic)
Attribute substitution is a theoretical framework that explains the pattern of many biases; it is not itself a single experimentally isolated effect.

Common mistake
Assuming that because your answer felt certain and effortless, you must have answered the right question — fluency signals accuracy even when it shouldn’t.
Practice this with IX Coach
IX Coach prompts you to name the target question and the question you actually answered before finalizing any judgment in a coaching session, making the substitution visible before it drives action.
