Time-sharing Experiments for the Social Sciences (TESS) offers researchers the opportunity to capture the internal validity of experiments while also realizing the benefits of working with a large, diverse population of research participants.

Investigators submit proposals for experiments, and TESS fields successful proposals for free on a representative sample of adults in the United States using NORC's AmeriSpeak® Panel, a probability-based and highly-respected representative survey platform.

The current principal investigators of TESS are Maureen Craig (New York University), James Druckman (Northwestern University), and Jeremy Freese (Stanford University). TESS was started by Arthur Lupia (University of Michigan) and Diana Mutz (University of Pennsylvania).

TESS is funded by the National Science Foundation (SES-2017581).

New Co-PI

With our new grant, TESS has added another co-Principal Investigator to our team: Maureen Craig (New York University). We are thrilled that Maureen is joining us!
