I became aware of this quite recently (on this site too IIRC), but it's worth noting that the "growth mindset" findings of the last several decades haven't quite panned out or been replicable upon further review: https://matheducators.stackexchange.com/questions/24418/are-...

I agree the Persistent / Obstinate paradigm seems quite similar, and if anything for those reasons I'm inclined to be (obstinately :P) skeptical.

Less relevant to engineering etc., but I personally find a lot of "successful people do X, unsuccessful people do Y" findings, especially when presented as "innate" or "personality" features, are pretty similar to IQ, the marshmallow test, and other things where it's a frequent victim of selection bias for how scarce resources were in one's upbringing or cognitive development.
