What happens to intelligence when people face extreme environments like prisons? In this episode we talk with Dr. Michael Woodley of Menie about his recent paper, “The Reversal of Spearman’s Hypothesis in Incarcerated Populations and the Role of Non-Shared Environmentality.”

We explore how one of the most established ideas in intelligence research completely reverses inside prison populations. Michael explains why harsh and unpredictable environments can trigger hidden talents and what that means for understanding IQ, cognition, and human adaptability.

In this conversation we cover:

What Spearman’s hypothesis really means
How non-shared environments shape cognitive differences
Why harsh environments can flip expected IQ patterns
The evolutionary explanation behind hidden talents
What this research means for testing and interpretation
