We will study the sensitivity of partisan cheerleading to financial incentives over a broad range of topics. We are particularly interested in the degree to which financial incentives may be able to decrease partisan cheerleading in some areas but not in others. We expect there may be a systematic pattern in the nature of these areas which we will test for in our survey.

Experimental Details


We will employ two surveys. The surveys will ask participants to state their beliefs on factually based questions. The two surveys will differ only on the marginal incentive for accurate answers where one will provide incentives for correct answers and the other will not.

Primary Outcomes

Primary Outcomes (end points)
We will determine the extent of partisan cheerleading by examining the difference between answers when incentives are and are not given for individuals whose political party affiliation differs.
Primary Outcomes (explanation)
Participants will be asked their political party affiliation and this will be linked to their answers on the factual based questions.

Secondary Outcomes

Secondary Outcomes (end points)
We will also examine if a link exists between CRT questions and answers on factual based questions.
Secondary Outcomes (explanation)
Participants will answers a few CRT questions. We measure the number of correctly answered CRT questions and link this to their political party affiliation and answers to factual based questions.

Experimental Design

Experimental Design
We will use a representative sample of the U.S. population. Approximately half of the sample will receive the incentivized version of the survey and the other half the unincentivized version.

Randomization Method
The survey company we will employ will randomize who receives the incentivized surveys and who does not.
Randomization Unit
Individuals will randomly receive either the incentivized or unincentivized survey.
