According to Peter L. Berger and Thomas Luck Mann, social reality is an immutable cultural construct

Peter L. Berger and Thomas Luckmann, in their seminal work "The Social Construction of Reality" (1966), argue that social reality is not immutable, but rather is continually constructed and reconstructed through human interaction and the process of socialization. They introduce the idea that society is a product of a complex social construction process, in which the knowledge and perceptions of individuals contribute to the creation of shared social reality.

Berger and Luckmann assert that this construct is not fixed; it is malleable and subject to change as individuals and groups of people interact with each other and reinterpret their experiences. Social constructs, including roles, norms, and institutions, are established by societies to bring order and predictability to human life. However, these constructs can be altered over time as people challenge and revise their beliefs and practices.

The authors identify three primary processes in the construction of social reality: externalization, objectivation, and internalization. Externalization is where individuals and groups create cultural products through social interaction. Objectivation is when these products take on a reality of their own, becoming independent of their creators and embedding themselves as legitimized elements of society. Internalization is the process by which individuals learn and absorb the various aspects of their culture and society, making them their own and perpetuating the established social constructs.
