Psychologists can't replicate Carol Dweck's 'Growth Mindset' claims: https://www.buzzfeed.com/tomchivers/what-is-your-mindset
> The findings of Dweck’s key study have never been replicated in a published paper, which is noteworthy in so high-profile a work. One scientist told BuzzFeed News that his attempt to reproduce the findings has so far failed. An investigation found several small but revealing errors in the study that may require a correction.
It is likely another hypothesized model from the social psychology field that doesn't actually exist, in the same category as Stereotype Threat and Power Posing.
It often just takes mentioning these concepts to someone for them to have an epiphany and get on the growth mind track.
I'm not sure they meant it this way but now that I'm older I realize that those 'gifts' could simply have been a healthy brain, free of any obvious learning disability, chronic fatigue or ADHD-like symptoms. And lo and behold, when I did in fact put in the effort I'd get Bs and As.
As a parent I use that approach with my son and, so far, it seems to be working.
If we only comment on how inherently good they are they might get lazy as whenever they get bad grades excuses like "I wasn't trying" works. It doesn't matter if the parents continue being surprised of the bad grades, the answer can also be "I was just lazy".
This is exactly what happened to me and I'm still trying to reprogram myself.
