How should you actually interpret an IQ score? When someone gets a score like 118 or 92, what does that really mean for their abilities and potential? Are there common mistakes people make when trying to understand what their IQ score tells them about themselves?
The most common mistake is treating IQ as a complete measure of worth or capability rather than one snapshot of specific cognitive abilities. A score tells you how you performed on that test on that day compared to the normative sample, nothing more.
Proper interpretation requires understanding: (1) The score shows current performance, not fixed potential; (2) It’s a percentile rank—118 means you scored higher than about 88% of people; (3) Subscores matter more than total IQ for understanding strengths and weaknesses; (4) The score has error margins, typically ±5 points; (5) It measures analytical reasoning primarily, not creativity, wisdom, emotional intelligence, or practical skills; (6) Performance can be affected by anxiety, motivation, fatigue, cultural factors, and test-taking experience. A score of 92 doesn’t mean someone is “dumb”—it’s solidly average and compatible with success in most careers. A score of 118 doesn’t guarantee achievement without effort, motivation, and opportunity. The biggest interpretive error is reifying the number as an identity rather than understanding it as useful but limited diagnostic information about current cognitive functioning.
