Harvard economist Roland Fryer made an appearance on The Colbert Report last night to discuss his new system of incentivizing students to learn more by paying them for good grades. (Check out their chat here). During the interview, Fryer said the achievement gap in America is "our biggest civil rights concern" and that it's time to "try innovative strategies" to correct it. On the lighter side, though, Fryer placed a bill (I believe $50) on the table for Colbert - but only if he asked good questions. And I chuckled (as did Fryer and the audience) at Colbert's query: "What is wrong with the older generation's way of doing things, where they paid kids to do well in school by not opening a can of unholy whup-a**?"
