Do love languages actually matter? What the studies found

Partly. Paying attention to how someone likes to be shown care does seem to help. But the core claims, that everyone has one love language and that there are exactly five, haven’t held up well when researchers tested them.

Where the idea came from

Gary Chapman’s book The 5 Love Languages names five ways people give and receive love: words of affirmation, quality time, gifts, acts of service and physical touch. It’s everywhere in dating now. People list it on profiles and bring it up on second dates.

The book makes three big claims, according to a 2024 review by relationship scientists Emily Impett and colleagues.1 Each person has a preferred language. There are five of them. And couples are happier when they speak each other’s.1 The review found the research so far doesn’t give strong support to any of the three.1

What does hold up

One part of the idea has real evidence behind it. A study of 100 couples measured how each person liked to receive affection and how their partner showed it.2 People whose partners expressed love the way they wanted to receive it reported more satisfaction with the relationship and with their sex life.2

So noticing what the other person responds to isn’t nonsense. That study shows a link, though, not proof that matching causes the happiness.

What doesn’t

The “one main language” part is where it falls apart. In a 2024 study of nearly 700 people in relationships, the researchers checked whether a partner’s behavior in your top language mattered more than in your other languages.3 It didn’t.3 Kind words and quality time predicted feeling loved better than people’s own top pick.3

The number five is shaky too. When the lead author’s team built categories from the ground up, 7 to 10 types of loving behavior described people better and predicted relationship quality better than Chapman’s five.4

So what should you do with it on a date?

Use it as a conversation starter, not a label. Impett and colleagues suggest thinking of love as a balanced diet rather than a language.1 Most people need some of everything: attention, affection, help and kind words.

Say you’re three weeks into seeing someone. Jordan, 26, told her date her love language was acts of service. He started doing favors. What she noticed most, though, was when he remembered small things she’d mentioned. That doesn’t fit neatly in any of the five boxes. Jordan isn’t a real person, but the mismatch between the quiz answer and real life is common.

If you’re early on and still figuring out how often to talk, see how often to text when you start dating. If you’re wondering whether they’re into you at all, do they actually like me? may help more than any quiz.

The fine print

Most of this research uses self-reports from people in long-term relationships, many of them married and older than the typical twentysomething dater. The couples study was small and only included heterosexual pairs. And the field is young: we have a handful of studies, not decades.
