Visi žinome, kad kai priimame sprendimus grupėje, jie ne visada būna teisingi. Kartais jie būna net labai klaidingi. Kaip grupės gali priimti gerus sprendimus? Kartu su savo kolega Dan Ariely, neuromokslininkas Mariano Sigman atlikdamas eksperimentus su didelėmis žmonių visame pasaulyje tyrinėjo, kaip žmonės bendrauja priimdamos bendrus sprendimus. Šiame faktų kupiname vaizdo įraše mokslininkas pasidalina savo gautais rezultatais ir savo išvadomis, kaip tai gali paveikti mūsų politinę sistemą. Tokiu metu, kai žmonės yra labiau susiskaldę nei bet kada anksčiau, Sigman teigia, kad geresnis supratimas kaip grupės bendrauja ir priima bendras išvadas gali parodyti naujus būdus, kaip sukurti klestinčią demokratiją.

Democracy and Deliberation: New Directions for Democratic Reform

This book proposes a new kind of democracy for the modern era, one that not only gives citizens more power but also allows them more opportunities to exercise this power thoughtfully. James S. Fishkin here suggests an innovative solution to the problem of inadequate deliberation, in particular within our presidential nomination system. His reform involves a well-publicized national caucus in which a representative sample of American citizens would interact directly with presidential contenders in order to reflect and vote on the issues and candidates.

Isaac Asimov | Ace, 1990 | Book

Robot Dreams (Remembering Tomorrow)

This book is recommended especially for the short story “Franchise” in which Asimov inquiries about our capacity to to sample a small number of votes to predict a total election outcome, and takes this idea to the extreme, reflecting on voting and deliberation.

Extraordinary Popular Delusions and The Madness of Crowds

A classic that still reflects the most relevant principles on why collective decisions may go wrong, and lead to misconception, and delusion. Written more than 150 years ago it seems that it is never been as relevant as in these days.

"Aggregated knowledge from a small number of debates outperforms the wisdom of large crowds"

Aggregated knowledge from a small number of debates outperforms the wisdom of large crowds. This preprint (accepted in principle in the journal Nature Human Behavior) presents the experiment described in the first part of the talk, providing experimental demonstrations that small debates lead to much more accurate collective judgments.
