The more intelligent you are, the more you can learn and potentially accomplish. [2] It is likely that the growth in neuronal connections is largely due to an interaction with the environment, as there is not even enough genetic material to code for all the possible neural connections.

The role of genetics in IQ becomes more prominent for late teens and adults. It could be hypothesized that the effect of these drugs on the development of the brain prenatally, and axon guidance could be the root of the negative consequences on later deficits in intellectual development. [59] Similarly, a study looking at young Belgian chess experts found that they have an average IQ of 121, a verbal IQ of 109 and a performance IQ of 129. Many psychologists believe that the idea that a test can be completely absent of cultural bias--a recurrent hope of test developers in the 20th century--is contradicted by the weight of the evidence.

[48], There is also evidence that birth complications and other factors around the time of birth (perinatal) can have serious implications on intellectual development. It was found that; IQ decreases during summer breaks from schooling, children with delayed school entry have lower IQ's, those who drop out of education earlier have lower IQ's and children of the same age but of one years less schooling have lower IQ scores. There is also evidence that the probability of a gifted child becoming a genius may be increased if the child has had to face adversity or trauma and that a traditional upbringing may encourage conformity and discourage the necessary divergent thinking.
