Description of Stanford Business School Video: When people want to make an impression, most think a lot about what they want to say. Stanford Business Professor Deborah Gruenfeld cautions you to think twice about that approach. The factors influencing how people see you are surprising: Words account for 7% of what they take away, while body language counts for 55%. There is a body language of power. Gruenfeld introduces the body languages of authority and being approachable. Becoming fluent in matching body language to each situation can be a source of power and influence. Gruenfeld also shares leading social science research on the ways in which body language affects your psychology, in addition to influencing how others perceive you.
