In the understanding of safety and risk, Vaughan is perhaps best known for coining the phrase "normalization of deviance",[7] which she has used to explain the sociological causes of the Challenger and Columbia disasters.[8][9][10] Vaughan defines this as a process where a clearly unsafe practice comes to be considered normal if it does not immediately cause a catastrophe: "a long incubation period [before a final disaster] with early warning signs that were either misinterpreted, ignored or missed completely."[11][12]
In the study of relationships, Vaughan is known for her research into the process of relationship breakups.[13][14][15][16]
