Apurity spiral is a theory which argues for the existence of a form ofgroupthink in which it becomes more beneficial to hold certain views than to not hold them, and more extreme views are rewarded while expressing doubt, nuance, or moderation is punished (a process sometimes called "moral outbidding").[1] It is argued that this feedback loop leads to members competing to demonstrate the zealotry or purity of their views.[2][3]
A purity spiral is argued to occur when a community's primary focus becomes implementing a single value that has no upper limit, and where that value does not have an agreed interpretation.[4]
One aspect that stands out in all purity spirals is the vanity of small differences, and the punishing of people for the most minor transgressions.
The term purity spiral was coined in one of the first systematic sociological accounts ofvictimhood culture,The Rise of Victimhood Culture: Microaggressions, Safe Spaces, and the New Culture Wars, where it is described as a form of infighting among both activists and members of victim groups.[5]
In a 2020BBC documentary about purity spirals, British journalist Gavin Haynes said that purity spirals punish people for "the most minor transgressions," and noted that they make it socially unacceptable to express a preference contrary to the group's.[1][4] Turkish-American academicTimur Kuran described this phenomenon in his 1995 bookPrivate Truth, Public Lies, calling itpreference falsification, and further noted the lack of incentives and systems to disrupt purity spirals, pointing out that even a small amount of opposition or doubt can lead to a greater wave of questioning within the group. French philosopherRené Girard also described many of the principles of the purity spiral, includingmimetic rivalry and thescapegoat mechanism, in his 1972 bookViolence and the Sacred.[1]
