Here’s how it works: when you set up your profile, you’re given a series of questions that you can elect to skip or answer, which then contribute to your match percentage with prospective matches (a.k.a. how compatible you are with someone). You’re only required to answer 15, but the average OkCupid user answers 50. The app then tells you if you agree or disagree with a potential match on an issue, or lets you click to find out. Because of this feature, you can find out if the person whose profile you’re checking out watches Game of Thrones, would date a messy person, or cares about climate change all in one glance.
