The Parentheses Riddle

A short original-research curio on one SSC-survey trick question (a parentheses-grouping puzzle). The striking finding: a strong AGE effect — people in their 20s were more than twice as likely as those in their 60s to pick the 'correct' answer. Scott rules out the obvious confounds (techie status, IQ, SAT, willingness-to-stare-at-the-survey, conscientiousness all explain little) and is genuinely stumped, tentatively guessing an age-related cognitive-decline effect specific to the parentheses-reading faculty (beyond IQ) and wondering about dementia-screening relevance. An EDIT notes the likely mundane explanation: younger people had probably seen the riddle before online.

Quality 54 · Solid. Solid (54). A fun little original-research curio with honest puzzlement, but slight, chart-dependent, and likely confounded (prior exposure, per the EDIT).

Claude’s paradigm shift 35 · Slight. Slight (35). A one-question survey curio; no developed idea.

Real-world impact 1 · Negligible. Negligible (1). A slight survey finding; no real-world footprint.
