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).
Changes to Short Study Limits
TESS's Short Studies Program (SSP) will now accept proposals of up to 6 items and up to 1,600 respondents. These changes will enable TESS to support shorter social science experiments more efficiently.
We are looking forward to more exciting research conducted with this program!
