according to the davis-moore thesis what is a role of social stratification
Davis–Moore hypothesis The hypothesis is an attempted explanation of social stratification, based on the idea of "functional necessity". Davis and Moore argue that the most difficult jobs in any society are the most necessary and require the highest rewards and compensation to sufficiently motivate individuals to fill them. Once the roles are filled, the division of labour functions properly, based on the notion of organic solidarity advanced by Emile Durkheim.[1]
Nature versus nurture The view that humans acquire all or almost all their behavioral traits from "nurture" was termed tabula rasa ("blank slate") by John Locke in 1690. A "blank slate view" in human developmental psychology assuming that human behavioral traits develop almost exclusively from environmental influences, was widely held during much of the 20th century (sometimes termed "blank-slatism"). The debate between "blank-slate" denial of the influence of heritability, and the view admitting both environmental and heritable traits, has often been cast in terms of nature versus nurture. These two conflicting approaches to human development were at the core of an ideological dispute over research agendas throughout the second half of the 20th century. As both "nature" and "nurture" factors were found to contribute substantially, often in an extricable manner, such views were seen as naive or outdated by most scholars of human development by the 2000s.[8][9][10][11][12][13]
