A novel experimental approach to study disobedience to authority

Abstract

Fifty years after the experiments of Stanley Milgram, the main objective of the present paper is to offer a paradigm that complies with up-to-date ethical standards and that can be adapted to various scientific disciplines, ranging from sociology and (social) psychology to neuroscience. Inspired by subsequent versions of Milgram-like paradigms and by combining the strengths of each, this paper presents a novel experimental approach to the study of (dis)obedience to authority. Volunteers are recruited in pairs and take turns to be 'agents' or 'victims', making the procedure fully reciprocal. For each trial, the agents receive an order from the experimenter to send a real, mildly painful electric shock to the 'victim', thus placing participants in an ecological set-up and avoiding the use of cover stories. Depending on the experimental condition, 'agents' receive, or do not receive, a monetary gain and are given, or are not given, an aim to obey the experimenter's orders. Disobedience here refers to the number of times 'agents' refused to deliver the real shock to the 'victim'. As the paradigm is designed to fit with brain imaging methods, I hope to bring new insights and perspectives in this area of research.

Experimental setup. Schematic representation of the experimental setup. Volunteers were in different rooms. The experimenter was located in a third, separated room. The agent heard on a trial basis the orders of the experiment through headphones and had to decide to press the ‘SHOCK’ or ‘NO SHOCK’ button. A real-time camera feedback displayed the hand of the victim of the agent’s screen so to allow to keep track on the consequences of their actions.

All tests were two-tailed.
