This game is part of ongoing research on popularity in social platforms. It is usually assumed that voting systems, like the one used on Reddit1, allow the "best" things to rise to the front page. However we don't know if this is actually true and there is a lot of interesting analysis which shows that things like the timing of your post has a large influence on its popularity2. So if factors that have nothing to do with the content of your post play a role in success, do voting systems really surface the best content?
This game explores this question by seeing if people, especially ones who use Reddit, can predict which image received more upvotes on Reddit. If you can keep your guessing score above 50%, then maybe Reddit's voting system reliably surfaces the best content. If not, there might be more to the story.
