Przeniesienie psychologiczne: Najpotężniejsza, powszechnie nieznana siła na świecie [Psychological transference: The most powerful, generally unknown force in the world] Paul R. Nail* (Department of Psychology and Counseling, University of Central Arkansas, Conway, USA) Evidence that negative maternal transference is at the root of Americans' beliefs in 9/11 conspiracy theories. Psychological transference occurs when one generalizes perceptions or feelings that originate from one or more persons usually in childhood, the source, onto one or more other persons or entities, the target - those perceived as similar to, or symbolic of, the source. The authors propose a mediational model in which (a) negative attitudes towards parents lead to (b) negative attitudes toward authority figures, in general, which lead to (c) beliefs consistent with 9/11 conspiracy theories. The model was tested with a sample of American college students (n = 86). Multiple regression analyses examining the hypothesized indirect effect of (b) above with bootstrapping (e.g., Mallinckrodt et al., 2006) supported the model - but only concerning students' attitudes towards their mother or mother figure growing up. Variables not associated with 9/11 conspiracy beliefs were: attitudes toward dad, attitudes toward mom and dad, political party affiliation, political liberalism/conservatism, and broken vs. intact families. Negative maternal transference appears to be a viable yet under-recognized explanation for beliefs in conspiracy theories. Discussion concludes with the possibility that Hitler's transference from his mother and father onto Germany and Austria, respectively, may have been the foundation for his twisted motives in starting World War II. *Joint work with: Corey L.
