Human beings hate change. They hate it on a deep, psychological level. In the 1940s, Kurt Lewin, the founder of modern social psychology, ascribed the phenomenon to the pressures and norms of our social groups and institutions. Explaining Lewin’s theory, NYU psychologist John T. Jost writes, “Resistance to change stems from the fact that we value the groups to which we belong, and therefore changing our attitudes or behavior is tantamount to leaving the comfortable embrace of a social reality of which we are a part.” Once our attitudes form, Lewin wrote, they freeze in place and are very difficult to unfreeze.
