Using data collected over three years and mimicking the methodology of Arnold et al. (2012) in Los Angeles, a study in Texas was conducted in which 66 families opened their homes and allowed video, survey data, and pictorial evidence to be collected. These data are used to determine if McDonaldization has spread from the public sphere into the private sphere by determining if the four factors of McDonaldization: predictability, calculability, efficiency, and control are present, and if so, in what ways they are represented. Ultimately, every single household studied showed instances of all four factors of McDonaldization, thus heavily supporting the hypothesis that McDonaldization has encroached into the private sphere. This phenomenon will be explained by using McDonaldization either as a rational means to pursue individualistic self-actualization as described through Maslow's Hierarchy of Needs or as a means by corporations to extend their own factor of control into the private sphere and thus influence consumers. Finally, the fifth factor of McDonaldization, irrationality emerging from rationality, was examined with examples provided.This is an open access article under the terms of the Creative Commons Attribution License 4.0, which allows use, distribution and reproduction in any medium, provided the original work is properly cited.

This theory draws heavily from Weber's (2003;1905) Iron Cage of Irrationality and describes the process by which rationality grows to the extreme of irrationality. However, while this process is heavily documented in several corporate and macro-sociological processes, particularly within the fast-food industry, there has not been any extensive research to determine the spread of McDonaldization into the private sphere primarily because of the theoretical barrier between the public and private spheres described by Habermas (1985).Our study draws upon the methodology of Arnold, Ragazzini, Graesch, and Och's (2012) Upon completion of the study, all sixty-five houses analyzed showed the presence of McDonaldization and each also exhibited several instances of irrationality that ultimately arises from McDonaldized systems according to Ritzer (1993).
