This trial does not extend or rely on any prior RCTs.
The importance of social media in recruitment is increasing. More and more people are open about many aspects of their personal life in their SM profiles and evidence from employers surveys and correspondence studies suggests data from social media is increasingly used and increasingly important in the hiring process. However, correspondence studies do not identify the individual making the decision, and so, are limited in their ability to describe the mechanisms behind this result. In our study, we use an experiment simulating the screening of job applicants to elucidate how the recruiter evaluation of the candidate is affected by the interaction between recruiter characteristics such as gender, education, and attitudes toward the social media, applicant characteristics available through social media profiles and lack of social media profile.

This is the second stage of an experiment conducted in March 2022, - AEARCTR-0008793
This is a supplement based on the findings in the previous round and the request of a Journal we submitted to.
This time, the experiment will be conducted with participants with hiring experience.

Primary Outcomes

Primary Outcomes (end points)
Application Score
Primary Outcomes (explanation)

Secondary Outcomes

Secondary Outcomes (end points)
Time spent on an application, Time spent on CV, time spent on SM, note length, questionnaire information
Secondary Outcomes (explanation)
While we don't measure time on CV and time on SM data separately, we intend to use the recording of the mouse click to give proxies for these measures.

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 combinations of CVs and SM data that vary according to work experience, education, interests, and gender. Subjects are asked to give each CV a score from one to ten. SM information includes - Control SM profile, Bad SM profile, Mental health issues, Employment gap, and lack of SM profiles.

This paper extends the literature studying the effect of social media content on the evaluation of job candidates. In a large-scale online experiment that resembles real-life screening of candidates for a job in the hospitality sector, we find that information available on social media through hashtags and liked pages can have a substantial and significant effect on a candidate's chances of obtaining a good rating. Candidates with social media content indicating mental health problems receive lower ratings by an amount equivalent to the effect of having three years on-the-job experience. Interestingly, candidates with no social media profile receive even lower ratings than candidates with mental health problems. In addition, unappealing social media content leads to the strongest reduction in ratings, equivalent to the value of nine years of on-the-job experience. These findings persist across participant pools, including both the general public and experienced recruiters, highlighting social media's substantial and likely increasing role in the hiring process.
