"The social sciences are almost completely a waste of money."
Commenter aniptofar, in reaction to this story...
U.S. researchers suggest paying students in school small amounts of money or prizes increases the number who ate fruit or vegetables at lunch.
Joe Price, an economics professor at Brigham Young University, and David Just of Cornell University, said previous research suggests a federal rule that prompted the nation's schools to serve an extra $5.4 million worth of fruits and vegetables each day, results in students throwing out $3.8 million of that produce in the garbage each day.
However, the researchers said paying students directly to eat a fruit or vegetable is less expensive and gets better results.
I think the commenter missed the point of the research. The point is that the government is already wasting the money on a program that children aren't buying into. Incentives might prove to waste LESS money. So I would modify the commenters comment:
The social sciences are Economics is almost completely about not wasting money.
