To Cheat or Not to Cheat

I was fairly bemused (a little appalled) to read this wsj article about how business schools had to cancel GMAT scores of quite a number of business school students/applications.

Apparently, there were folks that were selling questions so people could cheat. But what amused me amidst the main story was this line from the article:

Donald L. McCabe, a Rutgers University professor of management, has surveyed 200,000 students over 19 years and concluded that those in business school cheat more than those in other disciplines.

Sooo... does that mean business folks are more inclined to cheat/lie if you take the logical conclusion that those graduating from business school go into business?
