Contributor(s): Professor Cass Sunstein | What impact is behavioural science having on politics and business? Simplified disclosure, default rules, social norms, and ‘choice architecture’ are all being used to steer people in specific directions. Are these ‘nudges’ improving our decisions? Are they offsetting irrational behaviour? Cass Sunstein, author of Nudge and the previous Administrator of the White House Office of Information and Regulatory Affairs in the Obama administration will discuss these new policies and the question they raise about freedom of choice.
