Nature Vs Nurture Debate

The nature versus nurture debate is one of the most convoluted in the field of psychology and sociology. The use of the terms "nature" and "nurture" henceforth has referred to the roles of heredity and environment respectively in human development. Some scientists believe that human beings behave as they do in response to genetic predisposition. This is known as the nature theory of human behavior and is the view supported by naturalists. Other scientists think otherwise; that people think and behave in certain ways because they are taught to do so. This is known as nurture theory of human behavior and is the view of empiricists. There are theories of nature vs. nurture when it comes to intelligence and personality. In exploring the nature …show more content…

This group believes that personality is a result of evolutionary process. Human beings, it believes, inherit behaviors due to genes. As such, genes control their behaviors. They believe that form and characteristics measured with personality tests remain stable throughout a person’s lifespan. They further believe that human beings may sharpen their types or personality, but can never change them altogether. “Darwin's Theory of Evolution led naturalists such as George Williams, William Hamilton, and many others to the idea of personality evolution,” (Berger, 2013, p. 164). Evolutionary psychologists believe that behavior is a result of “natural selection in the environment of evolutionary adaptation (EEA), (Berger, 2013, p. 164). Interpersonal attraction therefore can be explained as a consequence of sexual selection. For example, men and women select partners who enhance their reproductive …show more content…

By altering the environment in which a person is raised, there can be some effect on the person's developing intelligence and personality. While this is true, the results of the twin studies were a useful tactic. These studies show that our genetics have a stronger influence than our environment. Across a variety of traits, including IQ, personality indicators such as political conservatism, religiosity, homosexuality, and neuroticism, identical twins are more similar to one another than are fraternal pairs. This indicates that genes affect these aspects of personality. “Gene - mapping studies have identified individual genes associated with high IQ,” (Berger, 2013, p.156). There is strong evidence for the effects of nurture, for example, the fact that IQs all over the world have increased as much as 20 points over 30 years. No matter where human beings are raised, it cannot completely change the genes that they are born with. These studies have produced substantive evidence of heritability. Indication suggests that family environmental factors may have an effect upon childhood IQ. On the other hand, by “late adolescence this relationship disappears, such that adoptive siblings are no more similar in IQ than strangers are,” (Berger, 2013,
