Eight People, Half the Try

More people should make better decisions—Condorcet proved it mathematically in 1785. But Ringelmann's rope experiment showed the opposite: eight people pull at half strength. The episode explores how decision fatigue, social loafing, and information pooling create this paradox, and how system design—not individual effort—is the actual fix. 00:01:46 - The Condorcet-Ringelmann Paradox 00:06:51 - Social Loafing and Information Pooling 00:11:57 - Decision Fatigue in Groups 00:15:15 - The Real Takeaway: It's System Design 00:17:00 - Escoffier's Kitchen Brigade Solution --- Sources & further reading: • Ivan Dale Steiner — Group Processes and Productivity (Academic Press, 1972) • Garold Stasser & William Titus — "Pooling of Unshared Information in Group Decision Making: Biased Information Sampling During Discussion" (1985, Journal of Personality and Social Psychology) • Fred Brooks — The Mythical Man-Month: Essays on Software Engineering (Addison-Wesley, 1975) • Maximilien Ringelmann — original rope-pulling research (~1913), rediscovered by David Kravitz & Barbara Martin — "Ringelmann Rediscovered: The Original Article" (1986, Journal of Personality and Social Psychology): https://www.researchgate.net/publication/209410111_Ringelmann_Rediscovered_The_Original_Article • Steven Karau & Kipling Williams — "Social Loafing: A Meta-Analytic Review and Theoretical Integration" (1993, Psychological Bulletin) • Irving Janis — Victims of Groupthink: A Psychological Study of Foreign-Policy Decisions and Fiascoes (1972) • Shai Danziger, Jonathan Levav, Liora Avnaim-Pesso — "Extraneous factors in judicial decisions" (2011, PNAS): https://business.columbia.edu/press-release/cbs-press-releases/how-extraneous-factors-impact-judicial-decisionmaking • Andreas Glöckner — "The irrational hungry judge effect revisited: Simulations reveal that the magnitude of the effect is overestimated" (2016, Judgment and Decision Making): https://www.sas.upenn.edu/~baron/journal/16/16823/jdm16823.html • Keren Weinshall-Margel & John Shapard — "Overlooked factors in the analysis of parole decisions" (2011, PNAS): https://www.pnas.org/doi/10.1073/pnas.1110910108 • Michael Saks & Mollie Marti — jury size meta-analysis (cited via Cornell Law and NYU Civil Jury Project): https://civiljuryproject.law.nyu.edu/better-by-the-dozen-bringing-back-the-twelve-person-civil-jury/ • Amanda Bergold & Margaret Bull Kovera — "Diversity's Impact on the Quality of Deliberations" (2022, Personality and Social Psychology Bulletin): https://doi.org/10.1177/01461672211040960 • Li Lu, Y.
