Kathryn Schulz used to write a column on Slate called "The Wrong Stuff" and her interviews with luminaries about being wrong were terrific. She's recently released a book, "Being Wrong" Adventures in the Margin of Error." Follow her on Twitter @wrongologist.
Her talk at TED 2011 on the power of being wrong and what failure can do to our ability to engage in the work at hand is a wonderful exploration of ego dynamic and how that plays into the teams on which we work.
"Trusting too much in the feeling of correctness can be dangerous. This internal sense of rightness that we all experience so often is not a reliable guide to what is going on in the external world."
Her talk from TED below is worth watching and reflecting upon in how we engage with those around us every day.
