When asked if she sees any context in which a fixed mindset is more beneficial than a growth mindset?

Well, first let me say that a growth mindset doesn’t require you to go around improving everything. You can focus and you can say no I’m not gonna do that, no I’m not gonna do that. But research, not my research but research of others has in fact looked at this question and found two areas so far in which a fixed mindset is better. One is sexual orientation. People who accept that this is who they are and this is who they’re meant to be seem to be better adjusted than people who think ‘I should be changing.’ And the other is aging. So, it’s nice to feel you can stay young through exercise and so forth but people who run around nipping and tucking and the tummy tuck and the this that and the other and it’s kind of a desperate attempt to retain extreme youth that doesn’t seem to be so great either. But when it comes to skill areas it looks like a growth mindset is typically more advantageous.

Dweck’s book, Mindset: The New Psychology of Success, is worth reading in its entirety.
