Barry Schwartz studies the connections between economics and psychology. In this, his latest appearance at TED, only days after Barack Obama’s first State of the Union address, Schwartz makes a passionate and rational call for a return of wisdom in our lives, our culture, our society and our businesses. Many times people spontaneously applaud, but Schwartz is more interested in getting his complete message across than in the accolades. If nothing else, you’ll have a great deal more respect for hospital janitors after hearing this presentation.
