Facebook Algorithms and Personal Data

Posted in: Research at 21/01/2019 00:56

About half of Facebook users say they are not comfortable when they see how the platform categorizes them, and 27% maintain the site's classifications do not accurately represent them

Most commercial sites, from social media platforms to news outlets to online retailers, collect a wide variety of data about their users’ behaviors. Platforms use this data to deliver content and recommendations based on users’ interests and traits, and to allow advertisers to target ads to relatively precise segments of the public. But how well do Americans understand these algorithm-driven classification systems, and how much do they think their lives line up with what gets reported about them? As a window into this hard-to-study phenomenon, a new Pew Research Center survey asked a representative sample of users of the nation’s most popular social media platform, Facebook, to reflect on the data that had been collected about them.

Many Facebook users say they do not know the platform classifies their interests, and roughly half are not comfortable with being categorizedFacebook makes it relatively easy for users to find out how the site’s algorithm has categorized their interests via a “Your ad preferences” page.1 Overall, however, 74% of Facebook users say they did not know that this list of their traits and interests existed until they were directed to their page as part of this study.
