In Simple Words
Think of a child's character like young bamboo rather than hard oak; while oak cannot be bent once fully grown, young bamboo can easily be trained to grow straight and resilient against heavy winds if guided while still young.
Fourth graders in 16 Istanbul schools
- Usual school activities
- Comparison group
- Grit curriculum
- Belief in improving ability rose
Sample B, January 2016: belief score rose by 0.36 standard deviations after the curriculum. This measures beliefs, not intelligence.
See source →Research question
Policy makers often assume character traits like perseverance are set in early childhood or genetically fixed, leading to underinvestment in targeted non-cognitive interventions during elementary school years.
Participants
N = 2,900 fourth-grade elementary school students (ages 8–10) across 52 schools in Istanbul, Turkey (Sample A: N = 1,717; Sample B: N = 1,203).
Study Design
Randomized Controlled Trial (RCT) evaluating school-level randomized exposure to a grit-fostering curriculum measured via post-treatment questionnaires and behavioral tasks.
Results
Treatment led to a 0.375 standard deviation increase in belief in skill malleability in Sample A (p < 0.01) and a 0.360 standard deviation increase in Sample B (p < 0.01), accompanied by a 0.300 to 0.368 standard deviation increase in self-reported perseverance.
Takeaway
Deploy non-cognitive development programs during middle childhood (ages 8–10) to capitalize on early brain plasticity before adolescent behavioral patterns solidify.

- Randomized controlled trial
A study that uses chance, like drawing lots, to decide who receives each option being compared. Researchers compare the groups’ outcomes to estimate the effect of those options.
ExampleA lottery assigns volunteers to a training programme or a comparison group. Researchers then compare their outcomes.
