Abstract
Studies show that CVs with typically black names receive fewer callbacks than otherwise identical CVs with typically white names (Zschirnt and Ruedin, 2016). However, studies in a more experimental setting have failed to replicate a penalty for black CVs (Kessler et al., 2019). One hypothesis for this discrepancy is that subjects hide their prejudice when they are being monitored. We test this hypothesis by measuring discrimination towards black CVs in the United States under conditions in which the subjects are either aware or unaware that they are being monitored.
(For Data after 23.06.2020 we extend the analysis to investigate which groups of people discriminate, and which groups react to their being monitored.)

(For data collected after 23.06.2020: the interaction of Trump Vote Share with Treatment Effect)
Secondary Outcomes (explanation)
(For data collected after 23.06.2020: Trump Vote Share is the share of people who voted for Trump in 2016 in the geographical area of participant, thus we are interested in how Trump voting areas differ from Clinton voting areas w.r.t. Treatment Effect)
Experimental Design
Experimental Design
Subjects are asked to read a job description for an office manager and then to assess a number of randomly generated CVs that vary according to work experience, education, interests, gender and ethnicity. Subjects are asked to give each CV a score from one to ten. The control group will only be informed of the task at hand. One treatment is informed of the task and asked to confirm that their input data will be scrutinised by our team. A second treatment is informed of the task and told that they are participating in an online experiment. Subjects are asked to give a general score out of ten for each CV and then three specific scores for experience, teamwork, and customer service respectively. This allows us to further detect the mechanism by which any ethnic discrimination takes place.

Randomization Method
Randomisation by computer program.
Randomization Unit
Individuals are randomly allocated to treatment. CVs are randomly generated.
