Quotation from "The Wire"

"Couple weeks from now, you're gonna be in some district somewhere with 11 or 12 uniforms looking to you for everything. And some of them are gonna be good police. Some of them are gonna be young and stupid. A few are gonna be pieces of sh*t. But all of them will take their cue from you. You show loyalty, they learn loyalty. You show them it's about the work, it'll be about the work. You show them some other kinda game, then that's the game they'll play. I came on in the Eastern, and there was a piece-of-sh*t lieutenant hoping to be a captain, piece-of-sh*t sergeants hoping to be lieutenants. Pretty soon we had piece-of-sh*t patrolmen trying to figure the job for themselves. And some of what happens then is hard as hell to live down. Comes a day you're gonna have to decide whether it's about you or about the work." - Daniels

Surprising Results from The Marshmallow Challenge

Tom Wujec compares the performance of various teams in a marshmallow building challenge and discovers a few results that might shock you.

The task is simple: in 18 minutes, teams of four must build the tallest free-standing structure out of spaghetti sticks and one marshmallow on top. The apparent simplicity of the task trips up many teams; about 40% of the teams end up with structures that buckle and collapse under the weight of the marshmallow.

Interestingly, kindergartners perform better on this task than business school students, lawyers, and CEOs. Kindergartners "produce not only the tallest structures, but also the most interesting structures of them all."

Why? The key to the kids' success is their "iterative" process -- trial-and-error that gives the team instant feedback on what works and what doesn't. Business school students, on the other hand, tend to rely on a single plan that ends up failing.

Wujec also finds that incentives have a strong impact on performance. When he "ups the ante" and offers a $10,000 reward, all of the teams during one challenge fail to build a standing structure. When he offers the same reward to the same group of design students four months later, the structures are much better than most other groups. Wujec concludes that
incentives + low skills = failure
incentives + high skills = success

Interesting stuff. If I were still a teacher, I'd run the experiment on my own students. You can view the instructions for the Marshmallow Challenge here.
