Expert Intuition: When Can We Trust It?
These notes to Kahneman’s chapter on expert intuition include the Getty kouros example and references on intuition as recognition. They raise a question about whether a strong expert hunch is reliable, without supplying the chapter’s full argument.

22: EXPERT INTUITION: WHEN CAN WE TRUST IT?

3 kouros: The Getty Museum in Los Angeles brings in the world’s leading experts on Greek sculpture to view a kouros—a marble statue of a striding boy—that it is about to buy. One after another, the experts react with what one calls “intuitive repulsion”—a powerful hunch that the kouros is not 2,500 years old but a modern fake. None of the experts can immediately say why they think the sculpture is a forgery. The closest any of them could come to a rationale is an Italian art historian’s complaint that something—he does not know exactly what—“seemed wrong” with the statue’s fingernails. A famous American expert said that the first thought that came to his mind was the word fresh, and a Greek expert flatly stated, “Anyone who has ever seen a sculpture coming out of the ground could tell that that thing has never been in the ground.” The lack of agreement on the reasons for the shared conclusion is striking, and rather suspect.

He wrote a classic on decision making in organizations while still in his twenties, and among many other achievements he went on to be one of the founders of the field of artificial intelligence, a leader in cognitive science, an influential student of the process of scientific discovery, a forerunner of behavioral economics and, almost incidentally, a Nobel laureate in economics.

When to use it
Art authentication: Experts rely on years of exposure to detect forgeries, but their intuition is only trustworthy in stable contexts with clear patterns.
Firefighting: Incident commanders use intuitive recognition of fire behavior based on experience, but must be cautious in novel situations.
Medical diagnosis: Experienced doctors can quickly recognize disease patterns, yet need to validate with tests in ambiguous cases.
Stock market trading: High-validity conditions are rare; many intuitive trades are unreliable due to market noise.
FROM THEORY TO EVERYDAY LIFE
In practice
The Getty Kouros
The Getty Museum consulted world experts on Greek sculpture to authenticate a kouros statue. Despite no immediate verbal rationale, many experts felt an 'intuitive repulsion' that it was a modern fake. Their inability to articulate reasons, and the vague explanations (e.g., 'fingernails seem wrong' or 'looks fresh'), illustrates both the power and the fallibility of expert intuition.
Chess Master's Recognition
As an illustration of intuition as recognition, an experienced chess player may identify a familiar position without consciously working through every move. Evaluating such a judgment still requires asking how the player learned the pattern and whether it fits this position.
A MOMENT TO REFLECT
Put it to work.
Think of a time when your own intuition led you astray. What conditions (e.g., lack of feedback, noisy environment) made it unreliable?
How can you distinguish between genuine expert intuition and overconfidence or bias in a given field?
In your professional domain, what environments have high validity for intuitive judgments, and which are low-validity and require analytical reasoning?
