L.L. Thurstone

L.L. Thurstone was a psychologist known for developing theories about intelligence and attitudes. He introduced methods to measure mental abilities and found that intelligence isn't just one thing but made up of several different skills. He also created statistical techniques to analyze how people hold different attitudes or opinions, helping us understand the complexity of human thoughts. His work laid the foundation for modern psychometrics, the science of measuring mental processes, by emphasizing precise measurement and recognizing multiple components within intelligence and attitudes.
