ABSTRACT
Egon Brunswik is not a familiar figure in the history of American psychology. Nevertheless, his contributions were such that a small group of researchers thought it fitting to establish the Brunswik Society, which meets annually to promote the approach to psychological research that Brunswik introduced. The impact of Brunswik's work on present-day research is found mainly in the application of his ideas to the study of judgment and decision making; Hammond and Stewart (2001) provide a comprehensive treatment of several aspects of his psychology by a variety of contributors. However, Brunswik's idea that the environment to which an organism must adjust presents itself as “semierratic” (Brunswik, 1955, p. 193), that is, as partly unpredictable by the organism, had a subtle, if typically unacknowledged, influence on American experimental psychology.
