If a 12-year-old child takes an IQ test and gets a score that indicates that he has an IQ below the average, does it mean that the probability of her having a normal IQ is almost zero?

Definitely not! Many 12-year-olds are not tuned into test-taking and make little effort toward scoring well, because they see the test as unimportant. Have her take the test in subsequent years to determine whether this was an exceptional instance and encourage her to do her best. Her performance in school and her subsequent IQ scores …

The more I learn about IQ, the more down-cast I become at this knowledge. Do you have any wisdom for those with lower IQs or learning difficulties (e.g. dyslexia) that wish to be successful in life?

In a meta-analysis of the relationship between intelligence and socioeconomic success, psychologist Tarmo Strenze surveyed a wide range of research papers dealing with the relationship between these two variables. His study yielded estimates of the correlation between IQ and income that ranged between 0.15 and 0.27. ( Strenze, Tarmo. 2007. “Intelligence and Socioeconomic Success: A …

How long would it take for an average IQ person to prove the Poincare conjecture?

Blog / By

It is unlikely that anyone of average IQ could solve the Poincaré conjecture. Before attempting a solution, a person would have to invest years of study to acquire the background necessary to understand what’s involved. Then a great deal of abstract thinking, involving very high-order thinking skills would be required. The mathematicians, Freedman, Smale, and …
