Windigo psychosis may well be the most perfect example of the construction of an Aboriginal mental disorder by the scholarly professions, and its persistence dramatically underscores how constructions of the Aboriginal by these professions have, like Frankensteins monster, taken on a life of their own. The 10th revision of the International Statistical Classification of Diseases and Related Health Problems (ICD) classifies "Windigo" as a culture-specific disorder, describing it as "Rare, historic accounts of cannibalistic obsession... Symptoms included depression, homicidal or suicidal thoughts, and a delusional, compulsive wish to eat human flesh... Some controversial new studies question the syndromes legitimacy, claiming cases were actually a product of hostile accusations invented to justify the victims ostracism or execution." As a concept or metaphor
In addition to denoting a cannibalistic monster from certain traditional folklore, some Native Americans also understand the wendigo conceptually. As a concept, the wendigo can apply to any person, idea, or movement infected by a corrosive drive toward self-aggrandizing greed and excessive consumption, traits that sow disharmony and destruction if left unchecked. Ojibwe scholar Brady DeSanti asserts that the wendigo "can be understood as a marker indicating... a person... imbalanced both internally and toward the larger community of human and spiritual beings around them." Out of equilibrium and estranged by their communities, individuals thought to be afflicted by the wendigo spirit unravel and destroy the ecological balance around them. Chippewa author Louise Erdrichs novel The Round House, winner of the National Book Award, depicts a situation where an individual person becomes a wendigo.
The novel describes its primary antagonist, a rapist whose violent crimes desecrate a sacred site, as a wendigo who must be killed because he threatens the reservations safety. In addition to characterizing individual people who exhibit destructive tendencies, the wendigo can also describe movements and events with similarly negative effects. According to Professor Chris Schedler, the figure of the wendigo represents "consuming forms of exclusion and assimilation" through which groups dominate other groups." This application allows Native Americans to describe colonialism and its agents as wendigos since the process of colonialism ejected natives from their land and threw the natural world out of balance. DeSanti points to the 1999 horror film Ravenous as an illustration of this argument equating "the cannibal monster" to "American colonialism and manifest destiny". This movie features a character who articulates that expansion brings displacement and destruction as side effects, explaining that "manifest destiny" and "western expansion" will bring "thousands of gold-hungry Americans... over the mountains in search of new lives... This country is seeking to be whole... Stretching out its arms... and consuming all it can. And we merely follow".As a concept, wendigo can apply to situations other than some Native American-European relations. It can serve as a metaphor explaining any pattern of domination by which groups subjugate and dominate or violently destroy and displace. Joe Lockhard, English professor at Arizona State University, argues that wendigos are agents of "social cannibalism" who know "no provincial or national borders; all human cultures have been visited by shape-shifting wendigos.
