Kai T. Erikson

Kai Theodor Erikson (February 12, 1931 – November 10, 2025) was an American sociologist, noted as an authority on the social consequences of catastrophic events.

Wayward Puritans Wayward Puritans is the title of his first book (1966) which contains a chapter on sociology of deviance and a chapter on the Massachusetts Bay Colony before three illustrations of deviance within the colony. The first was associated with Anne Hutchinson and Governor Vane and called the Antinomian Controversy. The second was concerned with an intrusion of Quakers, while the third was the Salem witch trials. The book notes the deviation from the City upon a Hill ideal set by John Winthrop.

H. Lawrence Ross described the book as "fascinating and superbly written". The sociological premise explored is from Émile Durkheim: "a function of deviance is to define the normative boundaries of the group." He notes that it is "a remarkable exception to the well-known tendency of sociological research to focus on the here and now." On the statistical analysis Ross comments: "the reasons to expect constancy of deviance over time, such as the limited capacity of the control system, would seem to predict stability of convictions as much as stability of offenders, and in consequence the analysis here seems unsatisfactory.”

Aftermaths of disasters Erikson subsequently studied a number of disasters in the context of their sociological implications, including the nuclear fallout in the Marshall Islands in 1954; the Buffalo Creek flood in West Virginia in 1972 (resulting in the award-winning 1978 book Everything in Its Path); the Three Mile Island nuclear accident in 1979; the Exxon Valdez oil spill in 1989; and the genocide in Yugoslavia of 1992 to 1995.
