Average IQ of Judges

Judges have an average IQ of approximately 122, slightly above lawyers, reflecting the additional cognitive demands of weighing complex evidence, applying legal principles to novel situations, and making consequential decisions that must withstand appellate scrutiny. Judges must process large volumes of complex information, evaluate competing arguments, assess witness credibility, and apply abstract legal principles to specific factual situations. The role requires exceptional executive function — the ability to remain impartial, control cognitive biases, and systematically work through complex decision trees. Judges must also write clear, logically structured opinions that explain their reasoning.
