Race and IQ

The definition of intelligence is a topic that has been the subject of debate in most of the world by different scholars.  A lot of effort has gone into defining intelligence and the different factors that influence a person’s intelligence. From the numerous studies that have been conducted over time, it is evident that both genetic and environment has a significant influence on a person’s intelligence. A person genetic composition determines how well that person can communicate, solve problems, and interact with other people. A study by (Plomin, Robert, and Sophie von Stumm 148), observes that identical twins have intelligence quotient that is almost similar than those of fraternal twin. Other studies have it that sibling who grow together in the same environment as adopted kids have similar Intelligence quotient than the adopted kids. This proves enough that genetics has a significant influence on a person’s intelligence. The genetic composition of the whites is different from that of the Black’s or any other race, which explains why there are differences in levels of intelligence between these races.

The impact that social factors have on an individual’s intelligence has also been studied. From the numerous studies, it is evident that social factors such as family, education, place of residence, family income, parents’ occupation, peer groups impact the intelligence quotient (Makharia, Archita, et al., 189). A study by &*6&, conclude that first-born kids are more intelligent than the subsequent kids. The rationale behind this is that first norms tend to get more attention from parents. According to Makharia, Archita et al., (189), suggest that children who go to school are more intelligent that non-school goers. Besides, how a kid is raised affects their intelligence. This draws support from Horta et al., (12776), who observed that children who breastfed more during the first three to five months are more intelligent than those who did not. Finally, the place or the environment where one is raised affects their intelligence quotient level. This draw support from the twin studies that observe that identical twins raised from different regions have intelligence quotients that are less similar than those raised in the same region are. In this, it is therefore right to say that people from different continents have different levels of intelligence quotient. The intelligence of blacks is influenced by the region they come from.
