I have always assumed that Dweck's point is not that IQ is malleable, but that effort ALSO matters. A specific example would be musical talent and practice - presumably for most accomplished musicians, practice plays an important role, and they wouldn't have gotten as far professionally on talent alone.

One reason so many parents are concerned about their children being "challenged" at school, is that they want to ensure the kiddos have the experience of seeing effort pay off, and to also thus allay perfectionist tendencies.

But perhaps I've misinterpreted her work?
