Much has been devoted to calculating the heritability of intelligence usually the I. It helps to understand our role in the world and our actions. Nature is what we think of as pre-wiring and is influenced by genetic inheritance and other biological factors. Early studies of intelligence, which mostly examined young children, found that measured 40—50%.
Depression, phobias, and reading disabilities have been examined in this context. Criminals in the making: Criminality across the life course. The author capitalizes on human nature and its development over time. Countless tests have been conducted to prove or disprove each theory, but the debate rages on. Because many scholars now view criminal behavior as the product of nature and nurture, many studies now exist that attempt to account for both processes. If our behaviour was in our genes then people all around the world would behave in the same way.
On the opposite end of the spectrum is behaviorism, which asserts that all behaviors learned by humans and animals are a result of their surrounding environments. Finally, Freud 1856-1939 characterized us as creatures of internal conflict. For example, it is hypothesized that a given behavioral disorder may represent an extreme of a continuous distribution of a normal behavior and hence an extreme of a continuous distribution of genetic and environmental variation. Those are nature and nurture, and the main purpose of this paper is to reveal the role of each element in human development from the psychological point of view.

Early biological theories of crime were strongly influenced by Darwinian views of inheritance and natural selection and tended to ignore or downplay environmental influences. Anthropologists are people who study and compare societies from all over the world.

Identical twins reared apart are far more similar in personality than randomly selected pairs of people. Fast-growing understanding of the human genome has made it clear that both sides of the debate have merit.

Sheldon and Eleanor Glueck, however, argued that the causes of crime were varied and multifaceted—and included biological factors. Nurture debate is hotly debated topic. Again, this is a nature theory of human behaviour because it supports the belief that our behaviour is pre-programmed to a large extent.
