The good folks at the Economist have come up with a suggestion about how to boost scores of American students on standardized tests: eat more ice cream. They notice this pattern in scores on the international PISA tests:
The more ice cream you eat the higher the scores, and a fairly robust correlation it is. Of course with the amount of ice cream we are already consuming, we (along with the Australians and Finns) should be doing better on the tests. And kids in Hong Kong and Singapore are significantly outperforming their meager ice cream consumption on the tests.
Could be a spurious correlation. Still, worth a try. I’m in.
