attribution of the causes of an event sources that are constant and unlikely to change over time or to sources that are dynamic and subject to variability over time, which may influence a person’s subsequent behavior in relation to that event. For example, a supervisor who believes that an employee unexpectedly absent from a recent meeting will also miss future meetings may reprimand the person, whereas a supervisor who believes the absence is not likely to be habitual may overlook the indiscretion. [proposed in 1979 by U.S. social psychologist Bernard Weiner (1935– )]
