How Do You Know seeks to reevaluate our modern-day conception of marriage by exploring the social, legislative, economic, and personal forces that drive people to — or away from — formalizing intimate partnerships through the state. Between the first same-sex couple to obtain a marriage license in the U.S., to an interracial couple who wed overseas due to anti-miscegenation laws in their home state, the documentary will weave highly personal, historically significant stories with contextual commentary from pertinent economists, policy-makers, historians, writers, and academics.
