Abstract
We study what black and white respondents know about the economic circumstances and opportunities of their own racial group, as well as the other racial groups. We check how these perceptions compare to reality and how they shape attitudes towards government intervention and policies. We randomly provide respondents information about the historical evolution of earnings for black and white men and women, as well as about the social mobility for black and white children and see how this shapes their views about racial disparities and government policies. We also conduct a simplified survey on very young people aged 13 to 18 to measure their perceptions and attitudes on race related topics. We focus on this age group since these teenage years are very impressionable years in which people form their views and this will help us to understand at what age certain attitudes already become well-established in people minds. We collect a second wave of respondents during the COVID-19 pandemic. Comparing them to the previous wave, we are able to check how this crisis affected people's perceptions and their policy preferences.

Experimental Details

Interventions

Intervention(s)
We elicit respondents' perceptions about the economic circumstances of their racial group and the other racial group, as well as about a range of government policies. In a randomized way, we provide respondents (the teenagers and the first wave of adults) with information about the historical evolution of earnings for black and white men and women, or about the social mobility, i.e., the likelihood that black and white children born in poor families make it to each quintile of the income distribution. In the second wave of adults collected during the COVID19 pandemic, we explain in a randomized way why poor people and black people are more likely to be economically affected by this crisis. The control groups sees no information.

Primary Outcomes

Primary Outcomes (end points)
We are interested in i) perceptions about the economic circumstances of one's own racial group and the other racial group, ii) attitudes and views about the economic circumstances and opportunities or discrimination for different racial groups, iii) support for various government policies related to redistribution or race.
Primary Outcomes (explanation)
We will construct summary indices (sum of z scores) to summarize i) misperceptions ii) attitudes towards racial discrimination and opportunities, iii) support for government policies.

Experimental Design

Experimental Design
We will randomize the information provided respondents. One group sees the historical evolution of earnings for white and black men and women; the other group sees probabilities of black and white children born in poor families to make it to each quintile of the income distribution; the control groups sees no information. In the second wave, one group sees the negative effect of the crisis on poor people; the other group sees the negative effect of the crisis on black people. We also randomize the order in which perceptions are elicited about black and white people (some see questions about black people first, others about white people first). We also randomize the amount of monetary incentives provided to respondents for correct answers.
Experimental Design Details
The experiment will consist in an online survey that will be sent to a representative sample of the US population along the age, income and gender dimensions. On the race dimension, the sample will consist of 50% white respondents and 50% black respondents. For the survey on teenagers, the sample will be representative of the US population along the income of parents and we will collect the same share along gender and age dimension. On the race dimension, here as well the sample will consist of 50% white respondents and 50% black respondents.
Participants will be asked to answer to different kind of questions. Initially, they will be asked questions on their background. In this way we will be able to collect the demographic characteristics of the participants and information on their socio-economic background. Then, they will be asked to answer many different questions that we regrouped in four blocks. The perception block, with questions on socio-economic characteristics of the US; the attitude block, where we ask the respondents view on race related topics such as discrimination; the race policy block, containing questions on whether respondents are in favor or against certain policies in favor of Blacks; and the redistribution block, where we try to understand which are the respondents preferences in terms of taxation and government expenditure. For the second wave of adults, we also ask some questions relative to the current COVID19 pandemic. All the questions can be found in the attached document.
The experiment is designed to have different layers of randomization. A first randomization will consist in the treatment assignment that will be showed after the background block, as discussed in more details in the "Intervention" section. Half of the participants will be randomly incentivized with an additional monetary compensation if they answer correctly to the questions in the perception block, those questions which have a correct answer. We will also randomize the order in which the questions block will appear. Finally, since we ask many times the same question both about Whites and Blacks, we will also randomize the order of these question. It will be done in such a way that half of participants will have to first answer to the question on Whites and then on Blacks, the other half the other way around.
