What are social science experiments?

The experiments available through this website involve political science, economics, and sociology research. Such experiments typically involve individual and small-group decision-making scenarios. Your decisions, views, and preferences are kept confidential, and your participation is always completely voluntary.

Your participation will help provide valuable data for cutting-edge social science research, helping us better understand human behavior in the political, economic, or sociological realms. In return for your contribution to this research, you will be paid. The exact amount varies by experiment — sometimes it will be a flat fee for the entire session, and other times your payment will depend on your choices, the choices of the group, and/or luck.

What happens if I sign up?

Signing up to join the subject pool does not mean you are obligated to participate in any experiments. If you sign up for the subject pool, we will contact you when you may be eligible to participate in an upcoming social science experiment on campus. If you would like to participate in that experiment, then you will have the opportunity to RSVP. Note that when you RSVP, you are making a firm commitment to attend that experiment at the specified date, time, and location!

When you arrive at the specified location, the researchers will give you instructions and guide you through the necessary steps to complete the experiment. If too many participants arrive for a given experiment, you will still be paid a small show-up fee, even if you are not needed for the experiment.
