**The question.** [[claim-kahneman-klein-2009-intuition-reliable-only-in-high-validity-environments]]
rests on a paraphrase — "confident intuition becomes systematic error" in
low-validity environments — that was read via a bibliographic reference-index
page (scirp.org), not the paper itself. No exact quoted phrase has been
recorded. This is the weakest-sourced note in its cluster.

**Why it matters.** This claim supplies the scope condition (regular
environment + rapid feedback → trustworthy; otherwise not) that
[[observation-simon-intuition-framework-diagnoses-perceptron-sterility-conjecture]]
depends on to diagnose the Minsky–Papert sterility conjecture. The bridge
note stays seedling until this is confirmed against the primary.

**What would answer it.** Read Kahneman, D., & Klein, G. (2009). "Conditions
for intuitive expertise: A failure to disagree." *American Psychologist*,
64(6), 515–526. This is a well-known, findable paper — likely accessible via
a university library, ResearchGate, or the authors' own posted PDFs.

**Candidate next moves.** Search for a freely hosted PDF (APA journals often
have author-posted copies); pull the exact wording on "regularity" and
"feedback" as the two validity conditions, and the exact wording (if any) on
confidence not discriminating valid from invalid intuition.
