Roscigno uses the guiding theoretical idea of social closure to explain discrimination in general. Max Weber first used the term "social closure" to describe the concentration of power.
Social closure is a "process of subordination whereby one group monopolizes advantages by closing off opportunities to another outside group beneath it which it defines as inferior and ineligible," according to the definition of the term.
According to Max Weber's idea of social closure, a dominating group maintains its status and advantages by restricting access to outsiders and monopolizing opportunities and resources for its own members.
According to the concept of closure, anytime an external stimulus only partially fits an item, individuals will fill in the gaps to view it as whole.
