A lot of psychological research has failed to replicate, throwing cold water on the entire field. “Grit” and the “growth mindset”, the two taglines of superstar researchers Angela Duckworth and Carol Dweck, checked all the boxes for predictive failure including the requisite TED talks (Duckworth, Dweck), best-selling popular books (Duckworth, Dweck) and genius awards and, to be sure, there has been lots of puffery about the “incredible potential” and “profound impact” of grit and the growth mindset. But, to their great credit, Duckworth and Dweck have taken the replication crisis to heart and have sought to address it. Working with a large team (PI David S Yeager), the authors have tested a growth mindset intervention in 65 randomly chosen schools with over 12,000 students representative of the United States grade 9 population.
