Is there a correlation between age and creativity? Do people tend to feel more creative as they get older? Is this perception or reality?

Blog / By

While we have a reasonably accurate knowledge of how intelligence changes with age, the question of how creativity changes with age remains under debate. Furthermore, it depends on the field in which creativity is measured. It is generally recognized that mathematicians and theoretical physicists reach the peak of their creativity before age 45. Other scientists …

The self-esteem of high IQ individuals spans the full range from low self-esteem to high self-esteem. Our personal self-evaluation, when it is linked to our perception of our ability depends to a large extent on the people to whom we compare ourselves.

Is it possible for a person’s brain to overload if they are able to understand all the mathematical formulas of Einstein and Newton?

Blog / By

A few years ago, I saw a cartoon in which a student, hand raised, asks his teacher, “Sir, may I leave the room; my brain is full?” The cartoonist has captured the natural perception that the brain is like a vessel with a limited capacity. Fortunately, the brain functions differently, otherwise we’d be unable to …

One of the most comprehensive studies of mathematical giftedness was conducted in the Soviet Union between 1955 and 1966, by a team of researchers headed by psychologist Vadim Krutetskii. In describing the results of this research, Krutetskii noted innate differences in the cognitive capacities of children. While carefully sidestepping the Soviet prohibition on linking talent …

Can someone be both intelligent and not creative? What is the Difference between intelligence and genius?

Blog / By

Francis Galton, who conceptualized the idea of intelligence, asserted that genius could not be attributed to intelligence alone. He attributed genius to “the concrete triple event, of ability combined with zeal and with capacity for hard labour.” In 1978, Joseph Renzulli, building on this idea, introduced what is known as his “three-ring” definition of giftedness. …

Can having one highly intelligent child affect the perceived intelligence of other children in the family?

Blog / By

Studies show that the IQs of siblings have only a moderate correlation (about 0.47) so it is not unusual for some child to be significantly more intelligent than their siblings. Traits that are defined by a complex combination of genes are less likely to be passed from one generation to the next intact. Hence height, …

How do individuals with a High IQ approach problem-solving? Do they tend to solve problems quickly or do they take their time?

Blog / By

One of the most important differences I’ve observed between those who are great problem solvers and those who are not, resides in their attitude. This seems strange, because IQ is crucial to strong problem solving ability. The greatest problem solvers approach a problem with the belief that they will be able to solve it. Fermat’s …
