Casey Gerald: The power of doubt

18:19 minutes · Filmed Feb 2016 · Posted Mar 2016 · TED2016

What do you do when your firmly held beliefs turn out not to be true? All his life, Casey Gerald has searched for something to believe in -- in business, in government, in philanthropy -- but found no easy answers. In this moving, personal talk, he urges us all to question our beliefs and embrace our uncertainty -- and, perhaps, find the courage to believe in something better.

"I need each of you to tell every young woman you know to be comfortable with imperfection." Watch »

Quote of the Week

A report found that men will apply for a job if they meet only 60 percent of the qualifications, but women, women will apply only if they meet 100 percent of the qualifications. 100 percent. This study is usually invoked as evidence that, well, women need a little more confidence. But I think it's evidence that women have been socialized to aspire to perfection, and they're overly cautious."
