In one of the first formal definitions of the relative deprivation,
Walter Runciman noted that there are four preconditions of relative deprivation (of object X by person A): • Person A does not have X • Person A knows of other persons that have X • Person A wants to have X • Person A believes obtaining X is realistic Runciman distinguished between
egoistic and fraternalistic relative deprivation. The former is caused by unfavorable
social position when compared to other, better off members of a specific group (of which A is the member) and the latter, by unfavorable comparison to other, better off groups. Egoistic relative deprivation can be seen in the example of a worker who believes he should have been
promoted faster and may lead that person to take actions intended to improve his position within the group; those actions are, however, unlikely to affect many people. Fraternalism can be seen in the example of
racial discrimination and are much more likely to result in the creation and growth of large
social movement, like the
American Civil Rights Movement in the 1960s. Another example of fraternalistic relative deprivation is the envy that teenagers feel towards the wealthy characters who are portrayed in movies and on television as being "middle class" or "normal" despite wearing expensive clothes, driving expensive cars, and living in mansions. Fraternalistic group deprivation has also been linked to voting behaviours, particularly in the case of voting for the
far-right. For example, a 2026 longitudinal study found that White Americans who perceived themselves as falling into a "last place" profile (i.e., tied in status with Black and Hispanic Americans while falling behind other White Americans) were the most likely to vote for Donald Trump and support bans on
Diversity, Equity, and Inclusion initiatives. Deprivation Theory is that people who are deprived of things deemed valuable in society, money, justice, status or privilege, join social movements with the hope of redressing their grievances. That is a beginning point for looking at why people join social movements; however, it is even more important to look at relative deprivation theory, a belief that people join social movement based on their evaluations of what they think they should have, compared with what others have. On the contrary, absolute deprivation is people's actual negative condition; relative deprivation is what people think they should have relative to what others have, or even compared with their own past or perceived future. Improved conditions fuel human desires for even better conditions and so can spark revolutions. ==Relativeness==
