“The Windigo in the Material World”, Robert A. Brightman1988-09 (history)⁠:

Reconsideration of documentary evidence indicates that the Subarctic Algonquian windigo complex was of probable prehistoric inception, that a correlative psychiatric disorder entailing cannibalistic ideation and behavior is historically demonstrable, and that existing ecological explanations of the complex fail to elucidate its origin, persistence, characteristics, and distribution.

Examination of the windigo complex from structural, pragmatic, and ideological perspectives suggests that instances of the psychiatric disorder were conditioned by Algonquian theories of dreaming and predestination.
