Intelligence, cognitive style, and psychological comparison
Philosopher
Father of Psychoanalysis
Radical independence of thought with prophetic intensity. High openness, low agreeableness. Challenged all conventional morality while battling chronic illness.
Extreme verbal intelligence paired with high openness. Built frameworks others now critique. Driven by ego and ambition but produced lasting conceptual innovation.
Historical IQ estimates are approximations based on documented achievements, contemporary accounts, and cognitive analysis. They should be viewed as educated estimates rather than definitive measurements. Both Friedrich Nietzsche and Sigmund Freud achieved remarkable things in their respective domains, and raw IQ alone doesn't capture the full picture of their intelligence and impact.
