Beer gets blame for violent crime rate
It is difficult to decide in this article whether the professor is confused or whether the reporter had so many different angles to report that it was not possible to make sense of the information. Perhaps the person who wrote the headline scanned the material to come up with the most attention-getting claim possible. The claim that a correlation between beer consumption and levels of violence for different countries is causal, is a classic case where one should suspect one or more lurking variables which may be associated with the two variables in question. The rest of the article rambles on about other characteristics of crimes and societies, some of which may be interesting but none of which contribute to the claim in the headline.
