I have made many foolish life mistakes over the years. Do you think that high IQ individuals tend to make less life devastating mistakes than low to average IQ individuals, in general?

Blog / By

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 …

If someone is good at math, does that mean that he/she is intelligent?

Blog / By

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 …

Why do hard sciences correlate with a higher IQ compared to soft sciences? Since soft sciences are more complicated, wouldn’t it be the reverse?

Blog / By

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 …

Is there a point in life (age) that your intelligence and ability to learn will be at its peak? At which point (on average) will this start to decline quickly?

Blog / By

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 …

What is the average IQ of students by their chosen degree? I just found an old statistic.

Blog / By

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 …

What is the correlation between IQ and job performance?

Blog / By

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 …
