A short clip, from 2003, of Noam Chomsky going through crimes of post-WW2 US presidents. He argues that they would be indictable under the Nuremberg principles.

A ten-minute explainer from Hypermind on the wisdom of crowds, covering Galton's discovery and the diversity theorem. It argues that collective intelligence comes from diversity, independence and aggregation.

Tom Scott explains Gricean maxims, the unwritten guidelines that shape how we understand each other. He uses examples such as why 'asbestos-free cereal' sounds suspicious.
