Nature-nurture debate

The nature versus nurture debates concern the relative importance of an individual's innate qualities ("nature", i.e. nativism, or philosophical empiricism, innatism) versus personal experiences ("nurture") in determining or causing individual differences in physical and behavioral traits. The view that humans acquire all or almost all their behavioral traits from "nurture" is known as tabula rasa ("blank slate"). This question was once considered to be an appropriate division of developmental influences, but since both types of factors are known to play such interacting roles in development, modern psychologists consider the question naive - representing an outdated state of knowledge. For a discussion of nature versus nurture in language and other human universals, see also psychological nativism.

The debate on the relative contributions of genetics (nature) and environment (nurture) to the characteristics of an organisms. As an example, the debate on whether gene(s) and/or environmental factors determine the sexual orientation of an individual. Finding a gene playing a role in the development of a condition does not necessarily mean it is a purely genetic trait.
