According to a recent study, the more beer a scientist drinks, the less productive he/she will be, at least as measured by the number of papers he/she publishes.
(Scientists, especially ones at universities, publish the results of their research in scientific journals. The more papers someone publishes, the better his/her professional reputation. In theory, at any rate.)
You can read about this, um, earth-shattering revelation here in the New York Times.
It’s worth reading this, however, for a counter-view. Maybe the important conclusion is that beer isn’t a brain enhancer?
