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 Jeremy Freese (Stanford University) and James Druckman (Northwestern 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-1628057).


Lupia-Mutz Outstanding Publication Award

Time-sharing Experiments for the Social Sciences (TESS) is celebrating its 20th anniversary! As part of our celebration, we are launching an annual best paper award.

The Lupia-Mutz Outstanding Publication Award is named for TESS’s founding principal investigators. The award recognizes the “best” paper that uses TESS data that is published (in print or on-line) in 2019, 2020, or the first half of 2021. The paper can use either primary or secondary TESS data, and it can either use TESS data exclusively or along with other data.

To be considered, send the paper to druckman@northwestern.edu by June 1, 2021. Self-nominations are welcome, as are papers from all fields and career stages of TESS users.

A committee consisting of the TESS principal investigators and Associate principal investigators will choose the winner by July 15, 2021. In addition to our accolades, the award comes with $500.
