Time-sharing Experiments for the Social Sciences, TESS2095 Piazza, Terrorism Suspect Religious Identity and Support for Controversial Practices

Data Archive > Other Data > Summary

TESS conducts general population experiments on behalf of investigators throughout the social sciences. General population experiments allow investigators to assign representative subject populations to experimental conditions of their choosing. Faculty and graduate students from the social sciences and related fields (such as law and public health) propose experiments. A comprehensive, on-line submission and peer review process screens proposals for the importance of their contribution to science and society.

The following study executes a survey experiment involving four treatment vignettes and one control vignette and 17 survey questions administered to 1,135 respondents. Respondents are randomly assigned to one of the five treatments which depict a short AP newswire blurb describing an arrest of two terrorist suspects in suburban Chicago. The treatments are identical to one another except they vary the names of the suspects (stereotypical Arabic/Muslim vs. Anglo-American) and the names of the terrorist movement the suspects are alleged to be members of (radical Islamists vs. right-wing American extremist). The control vignette omits any identification of the suspect names or groups. All respondents are then asked 13 questions rating their support for / approval of controversial interrogation and detention practices (10 interrogation practices, including the use of physical abuse of suspects, and three detention practices, including indefinite detention of suspects) that have been used by U.S. counterterrorism officials since the 9/11 terrorist attacks.

Sampling Procedures
TESS provides investigators an opportunity to run Internet-based experiments on a random, probability-based sample of the population. To achieve a representative sample, we contract with GfK (formerly Knowledge Networks), which conducts surveys using its KnowledgePanel. KnowledgePanel is a nationally representative, probability-based web panel based on dual-frame sampling that combines traditional random-digit-dialing telephone surveying techniques with an address-based technique that allows the sample to be representative of cell-phone-only households as well as those with land-lines. A summary of the KnowledgePanel survey design used for the TESS projects can be accessed here. Additional data and study materials can be downloaded here.
