(drum roll, please)
DRUNK COLLEGE STUDENTS ARE MORE LIKELY TO DO STUPID THINGS THAN SOBER ONES!
Shocker, isn't it? You'd think that with all the previous pioneering research in this field (Landis, J. et al. Animal House, Universal, 1978) further studies wouldn't still be needed.
Better yet is how they obfuscated the subject to make it sound more interesting: they put sex into it. This is a guaranteed way of getting your paper more attention than it deserves.
Basically, they interviewed 648 college students about "risky sexual behaviors" and found that if you're drunk you have a much higher incidence of having casual sex, or inebriated sex, or both. I suppose this could also be done using a more mundane topic such as "more likely to incorrectly sort the recyclables" but who would read that?
Since such information is hardly new, they decided to put a twist on it by studying risky sex following the consumption of energy drinks, both with and without alcohol. And, in a stunning conclusion, found that the incidence of banging near-strangers went up considerably when alcohol was involved, rather than just a plain old energy drink.
Now, on the surface this may sound like some vaguely interesting paper about regular energy drinks (such as Red Bull) vs. those mixed with alcohol (i.e. Jägerbombs) but let's face the facts: it basically found that alcohol consumption leads to a greater incidence of risky behavior than being sober. No shit, Sherlock.
You could do the same sort of research about coffee vs. coffee + bourbon, or milk vs. milk + schnapps. Those haven't been done yet, so if you're a grad student desperate to publish in the "Spiking Drinks Quarterly" (or just trying to meet girls) this is your big chance. Please see the definitive paper on the subject (Ramone, JJDTMR Somebody Put Something in My Drink, Sire Rec., 1985).
This research was supported (according to the article) by a government grant from the National Institute on Drug Abuse. Sadly, I'm not making that up.
