A great article talking about how our internal narratives of intrinsically motivated behavior is adulterated with extrinsic factors….
"They then divided the children into three groups. They offered Group A a glittering certificate of awesomeness if the artists drew during the next fun time. They offered Group B nothing, but if the kids in Group B happened to draw they received an unexpected certificate of awesomeness identical to the one received by Group A. The experimenters told Group C nothing ahead of time, and later the scientists didn’t award a prize if those children went for the colored pencils and markers. The scientists then watched to see how the kids performed during a series of playtimes over three days. They awarded the prizes, stopped observations, and waited two weeks. When they returned, the researchers watched as the children faced the same the choice as before the experiment began. Three groups, three experiences, many fun activities – how do you think their feelings changed?
Well, Group B and Group C didn’t change at all. They went to the art supplies and created monsters and mountains and houses with curly-cue smoke streams crawling out of rectangular chimneys with just as much joy as they had before they met the psychologists. Group A, though, did not. They were different people now. The children in Group A “spent significantly less time” drawing than did the others, and they “showed a significant decrease in interest in the activity” as compared to before the experiment. Why?
The children in Group A were swept up, overpowered, their joy perverted by the overjustification effect. The story they told themselves wasn’t the same story the other groups were telling. That’s how the effect works.”
