<p>But that’s irrelevant. Competent researchers either report the results of valid studies, or they report nothing. “Well it would be really hard to do a good study,” is not an excuse for reporting a bogus one. Why is a study with such a dramatic result not reported in a more high-profile journal?</p>
<p>On edit: Whatever problems there might be with this study, sample size is not one. The sample size looks fine, particularly when the differences in drinking turn out to be so enormous. Moreoever, “binge drinking” has a standard definition among researchers, so again, unless the researchers used some idiosyncratic definition, which is unlikely, the definition of “binge drinking” is not a problem with the study.</p>
