They used skulls, rulers, and fake science to decide who was human.This documentary exposes how pseudoscience was weaponized to justify racism.

In the 19th and early 20th centuries, so-called scientists claimed they could measure intelligence, morality, and worth by measuring skulls. This episode examines phrenology, craniometry, and scientific racism, revealing how false data and biased methods were used to justify slavery, segregation, colonialism, and genocide.

This is not fringe history. These ideas influenced governments, universities, immigration laws, and public policy — shaping racial hierarchies that still echo today. Through a narrative, evidence-based approach, this documentary shows how racism hid behind the language of science — and why confronting these lies still matters.
