What is considered deception in experimental economics?

Abstract In experimental economics there is a norm against using deception. But precisely what constitutes deception unclear. While consensus view that providing false information not permitted, are also “gray areas” with respect to practices omit or misleading without an explicit lie being told. this paper, we report the results of large survey among economists and students concerning various specific gray areas. We find substantial heterogeneity across respondent choices. The data indicate perception costs benefits matter, so such might in fact be appropriate when topic important no other way gather data. Compared researchers, have different attitudes about some methods scenarios ask about. Few express awareness no-deception policy at their schools. briefly discuss potential alternatives “gray-area” deception, primarily based on suggestions offered by respondents.
