Ambidexterity And Cognitive Closure

Scott tries to replicate Lyle & Grillo (2020) — that consistently-handed people are more authoritarian via 'need for cognitive closure' — on SSC survey data, and finds the OPPOSITE (ambidextrous respondents slightly more pro-Trump, less pro-immigration, more neoreactionary). He offers candidate explanations (a coding error, a Lizardman effect among rare answers, the Bay-Area-fashion reversal where low-closure Californians drift toward locally-forbidden right-wing ideas, disagreeable-blog selection), then builds his generative speculation: need-for-cognitive-closure as one of the brain's most basic parameters — 'settle quickly on the neon-sign answer' vs 'start open and possibly end somewhere crazy' — linking handedness, politics, sexual orientation, gender identity, optical-illusion susceptibility, and even the general factor of mental illness (ambidextrous people are more likely to have every mental illness in his data). Flagged repeatedly as 'irresponsible speculation.'

Quality 68 · Strong. Strong: a fun, generative survey-analysis with a memorable unifying speculation (NFCC as a cross-domain brain parameter) connecting to his optical-illusion/trans work; held mid-Strong by weak/marginal evidence and its self-declared speculative status.

Claude’s paradigm shift 52 · Moderate. Notable: the need-for-cognitive-closure-as-basic-brain-parameter framing spanning handedness/politics/sexuality/mental-illness is an original, provocative synthesis.

Real-world impact 2 · Minor. Within-discourse: an intriguing hook for the readership; no material reach.
