  • 7.6: Recommendation Algorithms on Social Media Platforms

    Recommendation algorithms, built into social media media platforms, Internet search tools, e-commerce sites, and other digital applications, influence people's behaviors and choices on a daily basis in widespread and often unnoticed ways.

    While algorithms are simply "instructions for solving a problem or completing a task" (Rainie & Anderson, 2017, para. 2), they can be used to shape thinking and behavior by doing things like suggesting "products, services, and information to users based on analysis of data" (Voice Tech Podcast, Medium, June 25, 2019, para. 2). For example, social media platforms use recommendation algorithms to determine what you should see on their sites (e.g., posts, sponsored ads, people) based on data about what you have viewed, bought, or done before.

    From a civics and government perspective, algorithms direct the flow of political information and news to readers and viewers. They are connected directly to the spread of misinformation and disinformation online. Yet as data scientist Noah Giansiracusa argues in his book How Algorithms Create and Prevent Fake News, this technology not only allows for the creating and disseminating of false and misleading content, but it has the potential to "save us from fake news by automatically detecting and labeling assertions and true or false" (2021, p. xi, para. 1).

    Looking into the emerging future, systems that have algorithms make everyday life decisions are being developed. Would you prefer having a life decision made for you by another person or a computer algorithm? How do you think most people would respond? The answer may surprise you...

    In a survey, 4,000 people were asked whether they wanted a human or an algorithm to decide for them if they would win a coffee gift card, get a bank loan, join a clinical trial for a promising medical treatment, or face a sizable money fine in civil court. In just over half of the situations, people preferred an algorithm to a human - when they believed the decision would made quicker, was cheaper, and would be more accurate (Bambauer & Risch, "Worse Than Human?" Arizona State Law Review 2021).

    On social media and e-commerce platforms, the goal of recommendation algorithms is to keep you on the site, app, or platform as long as possible to make more money. Advocates hail the convenience of personalized digital experiences, while critics worry that users experience only a narrow range of suggestions and choices.

    In the following activities, you will critically examine YouTube's recommendation algorithm and then design your own. You can also learn more at Defining Fake News and Finding Reliable Information in our Building Democracy for All eBook.
