Jay Belsky, a child development researcher, and Dalton Conley, a sociologist from Princeton, delve into how adversity can sometimes enhance resilience in children. Belsky proposes that early life stress may accelerate development, aiding survival despite health risks. Conley adds layers by discussing polygenic indices and their implications for social inequality. They explore how children's genes influence parental behavior and how changing environments can modify genetic impacts, revealing intriguing dynamics between nature, nurture, and society.

Episode notes
Adversity Can Be Evolutionarily Adaptive
- Childhood adversity can be adaptive when seen through evolution, not only harmful.
- Jay Belsky argues early hardship likely shaped developmental responses that increased reproductive success.
Adversity Often Accelerates Development
- Early life adversity often accelerates development, including earlier puberty and biological aging.
- Belsky links faster maturation to increased chances of reproducing despite health trade-offs.
Children Differ In Susceptibility
- Children vary in developmental plasticity: some are highly shaped by experience, others are not.
- Belsky's differential susceptibility predicts high-plasticity kids do best with support and worst with adversity.
