What Does This IQ Score Mean?
Psychologists generally agree that IQ captures a meaningful slice of cognitive ability — particularly in areas like abstract reasoning, pattern recognition, and verbal comprehension — but it's far from a complete picture. Many researchers emphasize that above a threshold of around 120–130, raw intelligence increasingly gives way to creativity, grit, emotional intelligence, and circumstance as determinants of real-world success.
