We are recruiting participants to download a browser extension that will collect anonymized data about your online experiences for research purposes only, and make small changes to which content you see on social media. We are doing this experiment to learn how to make social media better for people and society. At the end of the study, we will send you a personalized report on what’s in your feeds.

You must keep the extension installed for five months for the $10 reward. See the timeline below. You will also be enrolled in a drawing for $500. To get started, click the button above, then click the blue “Add to Chrome” button on the next page.
