The devices with which experimental economists account for and justify their own and their opponents’ views are investigated by examining transcripts of interviews with two participants in experimental economics. The earlier investigations of natural scientists’ discourse provide material for comparisons. The results suggest that in assessing an opponent’s deviating view experimentalists in economics can be more cautious than natural scientists to characterize their opponents as influenced by personal and social factors. Indeed, they seem to admit that to some extent both their own and their opponents’ behavior involves these influences. Regarding the development of disputes, the respondents constructed accounts where general optimism concerning the ability of empirical arguments to resolve disputes was linked with an idea of dialogues between theorists and experimentalists as vehicles of progress.
