McDonaldization is a sociological concept introduced by George Ritzer, describing the process by which the principles of the fast-food restaurant model, epitomized by McDonald's, come to dominate various sectors of society. This phenomenon involves four key dimensions: efficiency, calculability, predictability, and control, leading to standardized and uniform experiences. It highlights the shift towards a focus on speed and convenience, often at the expense of quality and individuality. Ultimately, McDonaldization critiques how such practices can lead to a dehumanizing and homogenized culture.
