This is the recruitment website for the Nuffield Centre for Experimental Social Sciences at the University of Oxford.

The Nuffield College Centre for Experimental Social Sciences (CESS) is an inter-disciplinary research Centre at Oxford University engaged in experimental work in the social sciences. At CESS we use laboratory, online, and field experiments in which we study human subjects engaged in decision-making tasks.

On this site you can register to participate in laboratory experiments. Participants in experiments receive payment for their time and effort. Payments usually depend on your decisions during the experiment, and average payments are typically around £10/hour. Experiments do not typically involve anything more than making decisions at a computer. If we run a session that involves something else, or has a different payment method, we will include such details in the advertisements for that particular session. Also please keep in mind that you need to be able to climb two flights of stairs to get to the lab. You will not be able to participate if you cannot get to the lab!

In order to participate, you first need to subscribe to the participants database via this web site (click on "Sign up" in the menu on the left side). Every now and then you will receive a message inviting you for a specific experiment. At that moment you can decide whether you want to participate in a specific experiment (see Rules).

On the left column you can find information about upcoming experiments (Calendar), read some common rules applying to all experiments and our privacy policy, as well as learn more about social science experiments and how to register (FAQ).

The Nuffield CESS is located at 3 George Street Mews on the 2nd floor.
