There is little neurological evidence that finds a difference between men and women. However there are psychological studies that do find a small difference in mental strengths. This interesting TED talk debunking psychological myths by a lecturer from the University of Liverpool discusses the psychological differences between men and women. Males and ...

Actual correlation between physical attractiveness and IQ is somewhere between insignificant and mildly positive, with a slightly higher correlation for men. The correlation between physical attractiveness and perceived intelligence is more significant. There are typically two approaches to explain this (nature vs. nurture): From an evolutionary ...

A lot of research seems to have been done on the challenges multilingualism poses for the human brain, but not so much on how much actually meeting those challenges improves one's overall cognitive capacity. At present the general approach seems to be summed up: "Cognitive science suggests that the brain has selective resources with limited capacity" (Emily ...

So you're basically asking what are the causes of interpersonal differences in intelligence as typically measured by standardised psychometric tests. This question forms the basis for a large proportion of the literature on intelligence. For example see a journal like Intelligence. For a review you could read Intelligence: Knowns and Unknowns A few quick ...

Your explanation limits your question to the present day United States. Richard Lynn (2004) indeed found that American Jews have a higher verbal intelligence than non-Jewish whites by an average of 7.5 IQ points. But since American Jews are largely descendants of European immigrants, their higher relative intelligence might be a result of so-called "eugenic ...

I hadn't heard of the Bhatia measure before. A little research (see page 42 of Sharma and Sharma) explains that it is a performance based measure of ability for children in India. In general, you should obtain the test manual to learn about the recommended scoring procedure. A quick Google suggests it might be available from here: http://www.npcindia.com/ ...

I'm inclined to see it as more a matter of statistics. Since you're asking a question of rank, the possibility depends on the population. For an extreme example, if you were the last man on earth, you'd be your own super polymath by default! Given a population of $N>7\rm B$, competition is of course much fiercer. Since the chance of being #1 in any skill ...

The relationships between race and IQ is a sensitive topic for many good reasons. It also raises a lot of deep questions about how to assess the role of genetics and environment. A good summary of the literature on Intelligence with a discussion of racial differences can be found in the article "Intelligence: Knowns and Unknowns" (FREE PDF). Within-group ...

To add to the existing answers (of which @what's gets special mention), an issue I don't think has really been addressed is the statistical reason for it being so difficult to measure extremely high IQs. By design, IQ is scaled so that it's normally distributed, with a mean of 100, and a standard deviation (SD) of 15. A well known feature of the normal ...

Einstein might have a fair point of view in this manner. He presumably is pointing out the balance between reading and creative thinking. too much reading causes people to not question critically and refrain from interpreting ideas in their own unique way, whereas reading and learning at your own rate and time can lead to more promising ways of understanding ...

There is no agreement among scholars about what intelligence might be. You must keep in mind that we cannot directly see intelligence. We don't even know if it actually exists! The idea of intelligence was invented to describe what we think might be the cause of certain observable behaviors, but there are others who think that we are throwing together ...
