Concept

Criminal Justice

Definition

Criminal justice is the system of laws, courts, police, and punishment through which a society responds to crime. It rests on assumptions about responsibility: who is to blame, who could have acted otherwise, and what a guilty verdict warrants.

Behave examines this system through the lens of biology, asking whether its core assumptions survive a close look at how behavior is actually caused.

Why it matters

How it works

The traditional system sorts offenders into the blameworthy and the excused, using a rough folk model of free will. Behave argues the model does not match the science: behavior is shaped by genes, brain damage, developmental adversity, and circumstance, and the line between "could not help it" and "chose to do it" is far blurrier than the courtroom assumes.

Sapolsky's proposed alternative borrows from public health and engineering. A car with failed brakes is removed from the road — not because it is wicked, but because it is dangerous, and only for as long as it stays dangerous. Applied to people, this reframes incarceration as quarantine and constraint aimed at protection and rehabilitation, rather than as the delivery of deserved suffering. The aim becomes less harm, not balanced moral scales.
