Abstract:
Although targeted advertising has been touted as a way to give advertisers a choice in who they reach, increasingly, ad delivery algorithms designed by the ad platforms are invisibly refining those choices. In this talk, I will present our methodology for "black-box" auditing of the role of ad delivery algorithms in shaping who sees job and political ads using only the tools and data accessible to any advertiser. I will demonstrate that a platform's algorithmic choices can lead to discrimination in delivery of job ads along gender and racial lines, even when such skew was not intended by the advertiser and is not justified by differences in qualifications. Furthermore, I will show that a platform's choices shape the political ad delivery by hindering campaigns' ability to reach ideologically diverse voters. I will conclude by discussing the implications of our findings for the necessity of third-party auditing and the open questions of how to enable such auditing while preserving privacy.
