It’s a must that we should know our IQ and once we knew it it is important to be informed what affects our IQ test result. There are several factors that influence the result.
Is intelligence inherited? The role of genes can play a great role. Heritability is a measure of the relative contribution of genes to the variation of a phenotype on a given group in a specific environment.
Health and intelligence are two closely-related aspects of human well-being. The impact of health on intelligence is one of the most important factors in understanding human group differences in IQ test scores and other measures of cognitive ability. Several factors can lead to significant cognitive impairment, particularly if they occur during pregnancy and childhood when the brain is growing and the blood-brain barrier is less effective. Such impairment may sometimes be permanent, sometimes be partially or wholly compensated for by later growth.
Almost all studies on heritability have been in the developed world, mostly in the United States. In developing nations there are many environmental factors affecting IQ which are much less important in developed nations. Examples include nutrition, diseases, environmental toxins, and health care. This likely affects heritability.
