Carol Dweck hasn't done science? Why would you say that? Do you say that because you don't feel that psychology is a science or is it because of something about her work in particular?

In any case my impression is that the article was about different strategies for improving achievement. I'm not a psychologist, but I've seen some pretty convincing articles that show that praise for how smart a kid is versus praise for how hard they work affects how they handle failure. Increasing perseverance would be a good way to be more successful in academia, I would imagine.
