Social development is regarded as the gathering of many individuals (a form of individualism as a whole), so as to interpret and study many disciplines. In the most extreme form, methodological individualism holds that the whole is only the sum of many individuals (atomism).

A laissez-faire attitude on economic policy issues. This attitude is nicknamed "Smithism" or "Manchester Doctrine" in Germany. No matter which economist, as long as he establishes his theoretical structure according to the assumptions about the behavior of a single family and enterprise, he will be suspected of praising the results of the free interaction of personal interests he described.

Within the scope of their main interest, that is, within the logical scope of economic mechanism, the method adopted by theorists in that period can be defended as methodological individualism, and their research results, as far as they are concerned, have not been substantially damaged because of the inherent limitations of this method.

Society is made up of individuals, and the only real foundation of social and economic activities is individuals. Without individuals, society would cease to exist. Any behavior in society is made by individuals, and a society or a collective can always make a difference through the actions of individuals who cooperate with each other.

Society or collective can't be concrete, only individual behavior can give society or collective concrete meaning; Analyzing and studying individual psychology and motivation is the starting point of analyzing and studying social phenomena. Only through individual analysis can we truly understand social phenomena and their essence. The analysis of social phenomena should be from individuals to society, not from society to individuals.
