RSA offers up another animated video explaining what makes us tick. This time, they're featuring a lecture by Daniel Pink, the bestselling author of Drive: The Surprising Truth About What Motivates Us. Revisiting research also found in Dan Ariely's new book, The Upside of Irrationality, Pink drives home the point that traditional motivation schemes – namely, bonuses – rarely achieve their intended results. In fact, the bigger the bonus, the bigger the decline in performance. Or so studies show again and again. So what does motivate us? The desire to be self-directed. The will to master something. The hope to make a contribution. It's all what Pink calls "the purpose motive," and it's the stuff that keeps this site moving along.
