It's true. Every time I read one of these OK Cupid analyses, I hear alarm after alarm in my head about bad statistics analysis. But I always read them anyway, because as long as you step back and think about it carefully, the data really is interesting.
An example of another minor quabble, iPhones are expensive. I would expect that owning one correlates with nicer clothes, makeup, and just more/better status symbols in general. It's no news that money is attractive.
