CONVERSATIONAL PROCESSES AND CAUSAL EXPLANATION

Causal explanation takes place in and takes the form of conversation. Explanations are selected by questions and are thus governed by general rules of discourse. A conversational model of causal explanation is introduced that explicates social aspects of the explanation process by postulating that good explanations must be relevant to the focus of a why question, as well as being true. The notion of explanatory relevance enables an integration of the major models of the attribution process by showing that they use the same counterfactual logic but address different causal questions. The conversational perspective suggests a reinterpretation of many attributional biases, and also highlights the role of interpersonal goals in generating implicit questions, which in turn constrain explanations. Finally, the relevance of the conversational perspective for research on causal networks, the social context of explanation, and intrapsychic explanation is noted.
