A good new article from Malcolm Gladwell. Looks at the problems that come when you (over) generalise, and how the conclusions you draw can be as wrong as they are right. Given that a lot of what we do in the comms arena is rooted in generalisation (conventional broadcast media buying for example), suggests we maybe need to think more before reaching for the stereotypes.
I found this on Brand New, which spotted it at Brandnoise - which is all a bit like a Malcolm Gladwell theory in its own right.
