From Jonah Lehrer, an illustration of the power of intrinsic motivation — the desire to do a thing because you enjoy it, rather than for any extrinsic reward like a paycheck:
Scientists have recognized the importance of intrinsic motivation for decades. In the 1970s, Mark Lepper, David Greene and Richard Nisbett conducted a classic study on preschoolers who liked to draw. They divided the kids into three groups. The first group of kids was told that they’d get a reward — a nice blue ribbon with their name on it — if they continued to draw. The second group wasn’t told about the rewards but was given a blue ribbon after drawing. (This was the “unexpected reward” condition.) Finally, the third group was the “no award” condition. They weren’t even told about the blue ribbons.
After two weeks of reinforcement, the scientists observed the preschoolers during a typical period of free play. Here’s where the results get interesting: The kids in the “no award” and “unexpected award” conditions kept on drawing with the same enthusiasm as before. Their behavior was unchanged. In contrast, the preschoolers in the “award” group now showed much less interest in the activity. Instead of drawing, they played with blocks, or took a nap, or went outside. The reason was that their intrinsic motivation to draw had been contaminated by blue ribbons; the extrinsic reward had diminished the pleasure of playing with crayons and paper. (Daniel Pink, in his excellent book Drive, refers to this as the “Sawyer Effect.”)
Pink defines the Sawyer Effect as “practices that can either turn play into work or work into play,” after Tom Sawyer, who tricked his friends into painting a fence for him by convincing them it was fun.
This week I am faced with yet another rewrite of my book, to answer more concerns raised by my editors — an entirely extrinsic motivation, with all that connotes. I’d rather be playing with blocks or taking a nap.
