QOTD

In educating myself this spring about education, I was aghast to learn that American children drop in I.Q. each summer vacation — because they aren’t in school or exercising their brains. – Nicholas D Kristof in the NYT

The IQ-metricians would have conniptions over this, because IQ is supposed to be largely genetically determined and fairly constant - hardly seasonally variable! I applaud anything that upsets IQ-metricians.
