Before your accept this review at face value, read the book for yourself.

This review, like many, fails to note that the data in question regards first- and second-year students (i.e., the second sample is in the third semester -- only 1 1/2 years after starting college). Many of us will recall that we made our big leaps in our junior and senior years, after declaring a major. In a later study, the authors claim that similar observations can be made regarding older students. Still, I would read this book with some skepticism.

For a more subtle review, try this one from the New Yorker: http://www.newyorker.com/arts/critics/atlarge/2011/06/06/110...
