Persuasion: Part 1

We all exert pressure on each other in ways small and profound. We recommend movies or books to a friend. We convince a colleague to take a different tactic at work. We lobby a neighbor to vote for our favored political candidate. This week, we launch the first of a two-part mini-series on the science of influence, and talk with psychologist Robert Cialdini about how we can all improve our techniques for persuading others.
