Grok fact-check: the '35,000 decisions a day' claim was never measured
arthurcolle · x · 2026-09-25
Asked for sources on the viral claim that adults make 35,000 decisions per day, Grok found no peer-reviewed support. It traces to a 2015 blog post by Joel Hoomans citing 'various internet sources,' repeated unsourced by HBR, CNBC and others; the closest real study is a flawed Cornell food-choice study (227 decisions/day). The 35,000 figure was never measured.
