Does Politics Influence Hiring? Evidence from a Randomized Experiment

An Erratum to this article was published on 11 August 2015


Do resumes with political “signals” make job applicants more or less likely to get hired? To test our theory that employers are more likely to hire like-minded partisans (and less likely to hire those of opposing partisan bents), we conduct a randomized experiment, sending out 1,200 politically branded resumes in response to help-wanted ads in two U.S. counties—one highly conservative and the other, highly liberal. In our pooled sample, we find that job seekers with minority partisan affiliations are statistically less likely to obtain a callback than candidates without any partisan affiliation. Meanwhile, applicants sharing the majority partisan affiliation are not significantly more likely to receive a callback than non-partisan candidates. These results suggest that individuals may sometimes place themselves at a disadvantage by including partisan cues on their resumes.

  1. We model our research design broadly off Bertrand and Mullainathan (2004).

  2. Critics question whether in-person audit and laboratory experiments that present employers with a binary choice—to hire one individual, for instance, either black or white—overestimate discrimination because they force employers to differentiate between artificially “equivalent” candidates. See, for instance, Heckman (1998).



  5. We also excluded Utah County, Utah, a county with a sufficiently large population that voted overwhelmingly for John McCain over Barack Obama in 2008 (76.5–18.5 %) ( based on concerns that partisan signals might activate differently in the predominantly Mormon county, given that—at the time of our experiment—there was widespread attention on Republican presidential candidate Mitt Romney’s Mormon faith.

  6. A possible issue with relying on voting behavior is that electoral outcomes may be swayed by exogenous factors that do not wholly capture party identification. Between 2008 and 2012 (when we conducted our experiment), the partisan compositions of these counties may have changed due to factors such as migration or shifting demographics. This does not seem to be the case, however. In the 2012 election, the percentages at which Collin County and Alameda County supported Mitt Romney were almost identical to the rates at which these counties supported John McCain in 2008 and likewise for Obama. If anything, there was a slight increase in the number of individuals voting Republican in Collin County in 2012. This ensures that we do have clear variation in the political leanings of our test districts: Collin County is highly conservative, and Alameda County is highly liberal.

  7. To preserve the anonymity of the experiment and the identity of employers who received fictitious resumes, this is not the actual name of a fictitious candidate.

  8. To minimize the possibility that employers distrusted the resumes or made attempts to verify their content, we tried to exclude any details in the resumes that might have been easily checked. Because our fictitious job seekers were recent college or university graduates, it is unlikely that employers would devote significant time or effort to verifying credentials. The risk of hiring is significantly lower in these entry-level positions, where pay tends to be more modest and responsibilities are fewer. We also reduced the chance that an employer might know the person with whom the fictitious applicant purportedly worked by describing past work in vague language and avoiding “name dropping,” which is consistent with how most applicants would describe their jobs, internships, and extracurricular activities.

  9. We also focused on entry-level jobs to minimize the burden on employer-subjects, who often review hundreds (if not thousands) of such resumes, and would only spend minimal time reviewing any fictitious applicant.

  10. Again, to protect the anonymity of the experiment and the identity of employers who received fictitious resumes, we omit the precise organizations and job descriptions here.

  11. One concern is that citizens may have been especially primed to think about politics during this period (leading up to and following the 2012 presidential election) because they were imbued with it every day in the news, on television, and via a cacophony of political advertisements. We acknowledge that partisan self-conceptions and stereotypes held by employers may have been especially activated during our experiment. But in the world of 24-hour news cycles and nearly nonstop campaigning, there is hardly a time when political priming is not salient in the United States.

  12. In applications sent by email, we rotated three generic cover emails including a salutation, a brief statement that the candidate was interested in the position and generic qualifications, and a closing. This ensured that the conservative, liberal, and the non-partisan resumes received roughly equivalent numbers of each generic cover email.

  13. Because the home addresses we attached to the applicants were fake, we could not track any correspondence by postal mail. Previous studies, however, suggest that it is extremely unusual for employers to contact job applicants through this medium (Bertrand and Mullainathan 2004), and we expect this to be even more pronounced today, with the expanded usage of email.

  14. To minimize the burden on employer-subjects, when a firm expressed interest in a job seeker, we notified the employer that the candidate had accepted a different position to ensure that no further time was spent reviewing a candidate than necessary.

  15. We have preserved the anonymity of employers in public dissemination of data to ensure that they do not face any reputational or legal liability for any perceived acts of discrimination. We could not have practically carried out this project with the prior consent of employers: Employers could well have acted differently if they knew they were reviewing applications for an experimental study.

  16. The unemployment rate ranged between 8.2 and 9.3 % in Alameda County during the experimental period, compared to 5.3 and 6.2 % in Collin County ( On the one hand, this may have made employers in Alameda County more likely to hire candidates with similar political affiliations because they could afford to be more selective due to the surfeit of job seekers. On the other hand, the smaller number of callbacks altogether makes it harder to achieve statistical significance.

  17. Use of a one-tailed test, which is our threshold throughout this article, is appropriate where the same steps would be taken in response to both a strongly negative effect and null effect (Ruxton and Neuhauser 2010). We are particularly interested in whether employers discriminate in one-direction: in favor of in-partisans (or against out-partisans).

  18. We also reestimate models 1–4 with fixed effects for each resume to pick up unobserved unit heterogeneity across job applicants. The results remain substantively unchanged.

  19. To ensure that our results are not sensitive to violations of distributional assumptions, we also reestimate all of our models with a nonparametric bootstrapping method. None of our substantive findings change.

  20. We conducted simulations using Clarify software (King et al. 2000).

  21. Emerging techniques might include mapping an individual human resource manager’s estimated political affiliation through his or her social media usage, including Twitter (King et al. 2012).

  23. One of the highest profile cases occurred in 2007, when Monica Goodling, a political appointee in the George W. Bush administration, became embroiled in a Department of Justice investigation for illicitly using partisanship as a factor in hiring assistant U.S. attorneys.

  24. Consider Chick-fil-A CEO Dan Cathy, who has publicly aligned himself with a number of conservative causes, including the defense of traditional marriage, or Ben Cohen, co-founder of Ben & Jerry’s Ice Cream, who has regularly endorsed liberal candidates ranging from Denis Kucinich to John Edwards.
