Experimental Design Details
Using two parallel experiments, we intend to study the causal effects of providing information about the number of Black people receiving benefits from two labor market policies (Temporary Assistance for Needy Families (sometimes referred to as welfare) and Unemployment Insurance) on support for these policies.
Each experiment will be conducted online (using Connect or Prolific) and will consist of three parts, each separated by two weeks. In the first part (lasting about 6 minutes), we will elicit basic demographic information, whether participants have previously benefited from either policy, political preferences, and both implicit (measured using an Implicit Association Task) and explicit attitudes towards race (measured through a statement of relative preference for Black and White). Respondents will be paid $1.25 for their participation ($15 per hour).
In the second part (lasting 5 minutes and paying a base wage of $1), participants will randomly be sorted into one of four conditions comprising two parallel experiments. In the welfare policy experiment, participants will be asked to estimate the fraction of welfare recipients during 2021 that were Black, how confident they are of this estimate, and then they will be asked about their support for welfare. Before reporting their support, half of these people (selected at random) will be shown the correct answer, so we will be able to assess the causal effect of providing this information on their welfare support, while controlling for their priors. The unemployment insurance experiment will be similar; however, instead of eliciting beliefs about the number of Black people using welfare, here we will ask participants to state their beliefs about how many Black people used unemployment insurance in 2021, how confident they are of this estimate, and then randomly provide half of them with the correct number before eliciting their support to estimate the causal affect of this information on respondent support for unemployment insurance.
In each experiment, participants are incentivized to provide the correct belief, with a bonus of $1 (in a five-minute experiment) for providing a belief that is within two percentage points on either side of the true number.
The third part of the experiment will test the persistence of both the intervention and treatment effects found in the second part. We will elicit incentivized beliefs about, and support for, both policies, which will allow us, in exploratory analysis, to consider the role of belief spillovers. Returning participants will be paid another $1 in base compensation, with the opportunity to earn another $1 in incentives. All belief bonus payments will be paid after the third part of the study is completed so that bonus payment cannot signal information about the correct racial composition beliefs to people in the control conditions.
