Actually, an IQ score of 120 for a person of any age corresponds to the 91st percentile. This means that you have scored higher than approximately 91% of all people who have taken that IQ test. Since IQ can change during the teenage years, your IQ when you become an adult may be a little …
I am 11 years old and my IQ is 120. Is that normal? Read More »
As you have probably seen throughout your life, everyone makes mistakes, but those of different levels of intelligence tend to make different kinds of mistakes. Based only on my personal observations, those in the lower levels of intelligence are more likely to make mistakes related to health issues, such as proper diet, adequate exercise and …
The short answer is “yes”, if your talking about being good at advanced mathematics. (A person who is good at the executing the algorithms of arithmetic may or may not be highly intelligent. Success at the more sophisticated forms of mathematics would be needed to confirm high intelligence.) In our technological society, people who excel …
If someone is good at math, does that mean that he/she is intelligent? Read More »
You raise a very interesting question. In the process of obtaining doctorates in both mathematics and the social sciences, I’ve lived in these two worlds and I think I can speak impartially about both. The lure of pure mathematics and theoretical physics is that they contain deep problems that are self-contained and require prolonged abstract …
I have so many books I treasure that it’s hard to select one. In my early years, it was E. T. Bell’s Development of Mathematics that gave me a perspective on the origins of this great body of human insight that we call “mathematics.” Since then, I’ve read tens of thousands of books on all …

The distribution of IQ among humans is described by the normal distribution having a mean of 100 and standard deviation of 15. In this description, the percentage of people with IQ less than 10 is virtually zero. At levels below 50, and above 150, IQ doesn’t have much meaning. Someone with an IQ below 50 …
In the 1940’s, psychologist Raymond B. Cattell attempted to create “culture-free” tests of intelligence. Believing that IQ tests contain implicit biases in favor of particular cultures, he sought to apply factor analysis to partition the g factor of intelligence (as measured by IQ) into two components–fluid and crystallized. He described fluid intelligence, as “a capacity …
Comparing average IQ’s across college majors can be misleading because the variation in IQ’s within a major is much greater than the variation across majors. That is, there is a very wide difference in the IQ’s of students in any particular major, so the person with the highest IQ in a major like education may …
I know of no research showing a correlation between IQ and the use of profanity. However, I would conjecture that there is a modest correlation between those two variables. Why? People usually resort to profanities when they are frustrated and are having trouble coping. This is much more likely to happen among those of low …

The efficacy of IQ tests in predicting job performance is well established in the research. Linda Gottfredson, one of the leading researchers in the implications of general intelligence, g, (as measured by IQ tests) states: (Gottfredson, Linda S. “Why g Matters: The Complexity of Everyday Life.” 1997. Intellignce 24 (1) pp. 79-132.) Personnel selection research …
