Technocracy is an organizational structure or system of governance where decision-makers are selected on the basis of technological knowledge. The concept of a technocracy remains mostly hypothetical. Technocrats, a term used frequently by journalists in the twenty-first century, can refer to individuals exercising governmental authority because of their knowledge. Technocrat has come to mean either "a member of a powerful technical elite" or "someone who advocates the supremacy of technical experts". Examples include scientists, engineers, and technologists who have special knowledge, expertise, or skills, and would compose the governing body, instead of people elected through political parties and businesspeople. In a technocracy, decision makers would be selected based upon how knowledgeable and skillful they are in their field.
