What does an IQ of [specific number] actually mean? I see people throwing around IQ scores but I don’t really understand what the numbers represent. Is a 120 IQ significantly different from 110, and how do these scores translate to real-world abilities?
Doesn’t IQ follow a bell curve where 100 is average and most people fall between 85-115? So wouldn’t each 15 points represent one standard deviation? But what does that actually mean practically? Like what’s the difference between someone with 100 IQ versus 130 in terms of how they think or perform?
IQ scores are standardized so that 100 is average and each 15 points represents one standard deviation. Here’s the breakdown: 85-115 is normal range (68% of population), 115-130 is above average to superior (14%), 130+ is gifted (top 2-3%), while 70-85 is below average and under 70 suggests intellectual disability. A 120 IQ means you score higher than about 91% of people, while 130 puts you in the top 2%. In practical terms, higher IQ correlates with faster learning, better pattern recognition, and stronger abstract reasoning. But the score alone doesn’t determine success. Motivation, creativity, emotional regulation, and practical skills matter enormously. Someone with 110 IQ and strong work ethic will often outperform someone with 130 IQ who lacks drive.
