-
Corrected unverified false precision added to Elstein, Shulman, and Sprafka's real 1978 medical-diagnosis research: the article claimed physicians formed diagnostic hypotheses 'within the first 4-6 minutes... from just 2-3 pieces of information,' but the real study and its secondary literature describe this qualitatively (hypotheses forming within seconds, from a handful of initial cues), never with these specific numbers.
What the page claimedArticle attached unverified precise quantitative figures to a real, well-documented study's qualitative finding.
What was correctedReplaced the unverified minutes/cue-count figures with the real study's actual qualitative characterization.
Why: The Chi, Feltovich, and Glaser 1981 physics-categorization study in the same article verified as fully accurate, including its University of Pittsburgh/LRDC institutional attribution.
