Intelligence: All That Matters by Stuart Ritchie is a good summary of modern intelligence research. https://www.amazon.com/Intelligence-That-Matters-Stuart-Ritc... To quote:
"The scientific evidence is clear: IQ tests are extraordinarily useful. IQ scores are related to a huge variety of important life outcomes like educational success, income, and even life expectancy, and biological studies have shown they are genetically influenced and linked to measures of the brain. Studies of intelligence and IQ are regularly published in the world's top scientific journals."
Psychology research has had a pretty dismal track record in terms of reproducibility (http://www.vox.com/2015/8/27/9216383/irreproducibility-resea...) and the growth mindset dogma in particular has been facing more and more robust criticism. Carol Dweck's work is far from the final word on the matter that this blog post portrays it to be.
Ironically, focus on a growth mindset may actually distract people from doing things that actually do have reproducible research showing they lead to more mental horsepower (e.g. regular aerobic exercise).
