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.

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.

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. 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.

This paper shows how (and why) social influence can undermine the wisdom of the crowds.

In 2016, TEDxperiments at TEDxRíodelaplata was performed by El Gato y la Caja. El Gato y La Caja (The Cat and The Box) is a communication, research and design collective whose goal is to spread the scientific way of seeing the world and the importance of making evidence-informed decisions. The collective conducts large-scale experiments in social psychology.

The TEDxRíodelaPlata event where we performed this experiment to ask how debates may improve collective wisdom.

This talk is part of the TEDxperiments project, in which we seek at TED to create new ideas in stage experiments. It asks why we often do not cooperate when it is optimal to do so.
