Cultural determinism is the belief that the culture in which we are raised determines who we are at emotional and behavioral levels. It contrasts with genetic determinism, the theory that biologically inherited traits and the environmental influences that affect those traits dominate who we are.

Yet another way of looking at the concept of cultural determinism is to contrast it with the idea of environmental determinism. The latter is the idea that the physical world- with all its constraints and potentially life-altering elements-is responsible for the make-up of each existing culture. Contrast this with the idea that we (humans) create our own situations through the power of thought, socialization, and all forms of information circulation.

It is also used to describe the concept that culture determines economic and political arrangements. It is an idea which has recurred in many cultures over human history, from ancient civilizations through the present.
