Insight into Your IQ
What does my IQ score mean?
Your IQ will help identify strengths and weaknesses in the aspects of intelligence our test measures. Your score will reflect where you lie compared to others in your age group. IQ tests are standardized to a median score of 100 and a deviation of 15. This means the most common score is 100 and 2/3rds of test takers score between 85 and 115. If your score is above 130 you're in the top 2.1% percentile.
How Accurate are IQ Tests?
IQ tests measure your score relative to others so accuracy depends upon the quality of data being used to calculate scores. Many online IQ tests standardize scores based upon online test takers which for a number of reasons do not provide an accurate data set on which to base scoring.
How Important is IQ?
Looking at the relationship between IQ and success statistically we do find reasonable correlations in most endeavors. It's no surprise that IQ is strongly correlated with academic performance but personality traits such as Conscientiousness are also strongly correlated independent of intelligence. In fact a study of 140 eighth grade students found Self-Discipline outdoes IQ in predicting academic success. IQ is correlated with success in creative fields but is better predicted by Divergent Thinking tests. A high IQ helps in many endeavors but is not required and often not the most important trait to possess.
Does IQ Predict Happiness?
Was Thomas Gray's 1742 poem onto something "Where ignorance is bliss"? The short answer is it depends. Analysis of 23 studies found no relationship between happiness and IQ so it would seem it doesn't matter. The same study did however find that nations with higher IQ's are very much happier than nations with lower IQ's. Your overall happiness is better predicted by traits such as gratitude and your genetic set point.
