Gain points and climb the leaderboard!

    Psychology research is currently facing a crisis: A significant amount of published studies cannot be reliably reproduced. Yet these studies will still be used in news headlines, and treated as fact. Research into social media has not been immune to this either, with the problem exacerbated by study designs that don’t match the real world. We built the Misinformation Game to aid in this problem. Our tool allows researchers to design social-media studies that look and feel like social media, while also making sure that each participant has a similar experience. This is really important for…
