Rethinking How We Measure Brainpower

For decades, society reduced intelligence to a single numerical score derived from formal testing. While clinical assessments remain a valid way to measure cognitive processing speed and memory, modern psychological research takes a much broader view of human intellect. Psychologists often look at your “g-factor”—your general intelligence—which influences everything from how you manage stress to the way you interact with authority. Intelligence is a highly dynamic trait that continually interacts with your personality, environment, and emotional landscape.
