In the zany 2008 romantic comedy “Yes Man,” Jim Carrey stars as Carl Allen. His character signs up for a self-help program based on the simple principle that guides comedy improvisation around the world: He says “yes” to everything.
Wait a minute. Although unleashing the power of “yes” initially transforms Carl’s life, he soon discovers the drawbacks of this powerful word. (Spoiler alert: At the end of the movie several hundred people get naked after Carl persuades them to donate their clothes to a homeless shelter.)
Now, MIT’s Sloan School of Management has climbed on the yes bandwagon. In a June 2013 study, researchers from the institute have suggested that the word “yeah” has a powerful ability to persuade our bosses or colleagues to agree with us.
