<p>I can explain a little of it, but great questions. First of all, the data. I’m using Williams data from its own student surveys and assuming that Dartmouth is going to be similar. Roughly 50% of the student body binged in the past two weeks (maybe slightly higher at Dartmouth, given its fraternity scene). Higher for white students, lower for minorities; higher for males, lower for females. Roughly 30% of the student body are heavy (near daily 2+ drinks a day) drinkers (again, higher for whites and males). Probably 20-25% of the student body are total abstainers, leaving moderate drinkers as the smallest group on campus. We are getting to really smallish numbers if we are looking for white male moderate drinkers.</p>
<p>Alcoholics develop tolerance over time. It takes more and more to get the same buzz; and more and more to appear drunk. Hangovers may be less frequent. At some point, for many, they will experience withdrawal symptoms if they don’t drink. Until the body breaks down, many are very high functioning (alcoholism, unlike other drug addiction, is not more common among lower income groups, and for neither alcoholism nor drug addiction does it sort by intelligence). And because of increased tolerance, work may be less affected than one might otherwise imagine (again, until the body begins to break down.)</p>
<p>It is very, very unlikely (statistically) that in a group of 10 friends going to Ivies or top LACs, 3 or 4 (higher at Dartmouth) will not be past two-week binge drinkers, unless they are Latter Day Saints or similar.</p>
<p>“Please humor me if this is a dumb question, since I am not, nor have ever been a drinker, nor do have I ever had a family member in that category.”</p>
<p>I know the exact feeling. Half a beer puts me to sleep. The gene for alcohol abuse/alcoholism just doesn’t exist in my family. So it has taken me almost a decade of professional work in the field to get my head around it, and it still strikes me as surprising. </p>
<p>But by the same token, I roomed with an alcoholic in college, and wouldn’t have been able to understand him as such until 20 years later.</p>
