Fair point, but you have to consider where the distinctions come from. For example, at MIT I'd be willing to bet the quantitative focus comes from the fact that many engineers who go there pick us business as a second degree as an undergrad. At Chicago, the quantitative/scientific focus stems from the fact that the department truly believes in it as a method of investigation. Chicago is all about the raw data and real life case studies. It's my understanding that many other business departments differ in this respect. Of course, this is all anecdotal evidence I've gathered from talking to Chicago alumni, so take it for what you will.
