Popular Psychology Through a Scientific Lens: Evaluating Love Languages From a Relationship Science Perspective

The public has something of an obsession with love languages, believing that the key to lasting love is for partners to express love in each other's preferred language. Despite the popularity of Chapman's book The 5 Love Languages, there is a paucity of empirical work on love languages, and collectively, it does not provide strong empirical support for the book's three central assumptions that (a) each person has a preferred love language, (b) there are five love languages, and (c) couples are more satisfied when partners speak one another's preferred language. We discuss potential reasons for the popularity of the love languages, including the fact that it enables people to identify important relationship needs, provides an intuitive metaphor that resonates with people, and offers a straightforward way to improve relationships. We offer an alternative metaphor that we believe more accurately reflects a large body of empirical research on relationships: Love is not akin to a language one needs to learn to speak but can be more appropriately understood as a balanced diet in which people need a full range of essential nutrients to cultivate lasting love.
