Impacts of Social Media Recommendation Algorithms
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 largely 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.
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 these activities, you will examine YouTube's recommendation algorithm and then design your own.
Activity 1: Evaluate YouTube's Recommendation Algorithm
- Login to Gmail and then go to YouTube.com.
- Closely examine the suggested videos on your YouTube homepage.
- Do the recommended videos seem to accurately represent your tastes?
- Does anything seem out of place?
- Then, open up an incognito or private browser (where you are not logged into gmail), go to YouTube, and examine the suggested videos on the homepage.
- How are the videos different from the ones suggested when you were logged into Gmail?
- What surprises you about the differences or similarities between the two sets of recommended videos?
- What data do you think YouTube is using from you to determine the suggested videos for your homepage when you are logged into Gmail?
- Next, click on a video and closely examine the list of "recommended" videos on the right-hand side of the screen.
- Why do you think these videos were suggested?

- Finally, create a social media campaign to respond to the following prompt: How might recommendation algorithms influence the news that people get from social media, Internet search tools (e.g., Google search), and other digital applications?
- The social media campaign should include at least 2 videos (e.g., YouTube, Snapchat, TikTok), 5 example posts, and 3 images (e.g., memes, graphics, infographics) designed by you.
- Here is a social media campaign example created by Justin Lo, Daniel Mulno, and David Warde and here is a Twitter campaign example by Sara Shea.
- Consider using the Made to Stick principles or TED Talk presentation techniques to increase the appeal of your social media campaign.
Activity 2: Design a News Recommendation Algorithm
- Explore Algorithms for Kids or Initiation to Algorithmics with Scratch (advanced)
- Then, design a simple algorithm in Scratch in which a user can input data about themselves (e.g., interests, political leaning, location) and get a recommended News site or article to explore.
