People with higher psychometric intelligence have, on average, larger brains, and possibly faster neural conduction speed. A few small functional brain-scanning studies suggest that, in healthy individuals, people who are of higher IQ have lower cerebral metabolic rates during mentally active conditions.
Geniuses have a denser concentration of mini-columns than the rest of the population – it seems that they simply pack more in. Mini-columns are sometimes described as the brain's 'microprocessors', powering the thought process of the brain. Research shows that geniuses have fewer dopamine receptors in the thalamus.
Overall, larger brain size and volume is associated with better cognitive functioning and higher intelligence. The specific regions that show the most robust correlation between volume and intelligence are the frontal, temporal and parietal lobes of the brain.
Smart People Really Do Think Faster The smarter the person, the faster nerve impulses zip around the brain, a UCLA study of brain scans finds. And this ability to think quickly apparently is inherited.
In intelligent persons, certain brain regions are more strongly involved in the flow of information between brain regions, while other brain regions are less engaged. Differences in intelligence have so far mostly been attributed to differences in specific brain regions.
People with high IQ test scores remembered first and second memories at an earlier age than did those with lower IQ test scores.
Researchers have previously shown that a person's IQ is highly influenced by genetic factors, and have even identified certain genes that play a role. They've also shown that performance in school has genetic factors. But it's been unclear whether the same genes that influence IQ also influence grades and test scores.

Research has shown that there is a high correlation between being intelligent and socially anxious. The higher your IQ, the higher the chance your social apprehension is higher than usual. Of course, that doesn't mean that your social anxiety should be classified as a disorder.
Brain size has a surprisingly small impact on intelligence and behavior. Key Points: Having an unusually large brain doesn't necessarily make someone a genius, and large-scale research suggests only a slight and tenuous relationship between brain size and intelligence.
Early twin studies of adult individuals have found a heritability of IQ between 57% and 73%, with some recent studies showing heritability for IQ as high as 80%. IQ goes from being weakly correlated with genetics for children, to being strongly correlated with genetics for late teens and adults.
The ability to store more items in short-term memory indicates a higher IQ, psychological research reveals. While there may be no limit to long-term memory, short-term memory is much smaller. The average number of things people can store in short-term memory — whether words, numbers or whatever — is four.
While intelligence is, of course, a prerequisite of genius status, there are other things at play here – including creativity, self-awareness, and an innate ability to ask questions few others have ever asked.
Summary. Geniuses are both born and made. While genetics can explain up to 75% of variations in IQ levels, factors like socioeconomic status and home environment decide whether a person achieves their full genetic IQ potential.
Geniuses think productively, not reproductively
They tend to come up with many different responses, some of which are unconventional and possibly unique. Leonardo da Vinci believed that to gain deep knowledge about a problem, you have to learn how to restructure it in many different ways.
Slow thinking is more deliberate, requiring "attention to the effortful mental activities that demand it, including complex computations." It kicks in when you focus, pay attention, monitor and control your behavior, formulate an argument, solve a problem, or do anything that causes your brain to exert itself.
Physical exercise can help you learn and think faster, focus better, and remember more. One huge study on over 1 million men found that exercise can actually raise IQ. All exercise is good for your brain, but aerobic exercises like walking, jogging, swimming, or biking specifically improve processing speed.
Difficulty communicating or socializing with others. Lower than average scores on IQ tests. Difficulties talking or talking late. Having problems remembering things.
Those with high IQ had higher risk for psychological disorders (RR 1.20 - 223.08). High IQ was associated with higher risk for physiological diseases (RR 1.84 - 4.33). Findings lend substantial support to a hyper brain/hyper body theory.
Like most aspects of human behavior and cognition, intelligence is a complex trait that is influenced by both genetic and environmental factors.
Genetics as an intelligence determiner
Several studies with twins2 and studies with fraternal siblings have identified intelligence as one of the highest heritable traits. In other words, just as someone with tall parents is likely to be tall as well, someone with smart parents is also likely to be more intelligent.
We inherit a set of 23 chromosomes from our mothers and another set of 23 from our fathers. One of those pairs are the chromosomes that determine the biological sex of a child – girls have an XX pair and boys have an XY pair, with very rare exceptions in certain disorders.
