One of our notebooks in the August issue takes a close look at press releases about research, and why some press offices choose to cover seemingly obvious research. We only mentioned one university-based press office, but it's not just Ohio State University that "sells the self-evident," as a press release that landed in my inbox last week demonstrates.

"Mizzou study shows that possessing a fake ID results in more drinking by underage college students," the University of Missouri-Columbia release reads. The study, from professor of clinical psychology Kenneth Sher and his colleagues, showed that owning a fake ID increased the risk of drinking among students in their first two years of college. Also, students who belonged to fraternities or sororities were more likely to own a fake ID.

"The biggest finding is that having a fake ID is a risk factor for additional drinking -- drinking that might not otherwise be occurring," Sher said in the release. "Basically, being a heavy drinker predicts the likelihood that someone will obtain a fake ID, and having a fake ID predicts that someone will be a heavy drinker."

Um, yeah. Am I missing something?

The study, which asked 3,700 in their first four semesters of college about their drinking habits, was published in the American Psychological Association journal, Psychology of Addictive Behaviors.
