Watch this lecture by Sheena Iyengar, a professor at Columbia University Business School. Iyegar studies how we make choices and how we feel about the choices we
make. Speaking at a TEDGlobal conference, Iyengar discusses both trivial
choices (such as deciding whether to drink Coke or Pepsi) and profound
ones. Iyengar's groundbreaking research has uncovered some surprising
attitudes about our decisions.
