The average adult falls passionately, consumingly in love (the kind that wrecks your appetite and keeps you staring at the ceiling at 2 a.m.) just 2.05 times across an entire lifetime, according to a new study from the Kinsey Institute at Indiana University. Researchers surveyed 10,036 single U.S. adults between the ages of 18 and 99, and 14% of them, roughly one in seven, said they had never felt it at all. Another 28% had felt it exactly once. This isn’t a portrait of a life stuffed with whirlwind romances. It’s evidence that passionate love is a genuinely rare event, one most people will count on one hand for their entire life.
The findings come from a paper titled “Twice in a Lifetime: Quantifying Passionate Love in U.S. Single Adults,” led by researcher Justin R. Garcia and published in Interpersona: An International Journal on Personal Relationships. It’s the first large-scale attempt to actually count passionate-love episodes across a nationally representative adult sample, rather than asking people to describe their current relationship or recall a single memorable one. The team defined passionate love the way psychologists typically do: an intense state of longing, preoccupation, and physiological arousal for another person, the can’t-eat, can’t-sleep, can’t-think-about-anything-else version of romance, distinct from the steadier companionate love that often follows it.
Here’s how the full distribution broke down:
- Never experienced it: 14%
- Once: 28%
- Twice: 30%
- Three times: 17%
- Four or more times: 11%
That means the mode, the single most common answer, is “twice,” and a full 42% of adults have experienced it either zero or one time. Put another way: more people top out at a single passionate love in their life than experience it three or more times. As the Kinsey Institute’s Dr. Amanda Gesselman put it, “for most people, passionate love turns out to be something that happens only a few times across their entire life.”
The researchers also looked at who reports more or fewer episodes, and the differences were modest rather than dramatic. Older adults reported slightly more instances than younger adults did, which tracks, since they’ve simply had more years and more relationships in which it could occur. Among heterosexual respondents, men reported marginally more passionate-love episodes than women. But experiences were broadly similar across heterosexual, gay, lesbian, and bisexual participants, suggesting the phenomenon itself, however it gets triggered, isn’t confined to one kind of relationship or orientation.
What makes the number 2.05 land differently than most relationship statistics is that it cuts against the cultural script most people absorb from movies, songs, and social media, where falling head-over-heels reads as something that ought to happen fairly often if you’re doing dating “right.” The same research context notes that 60% of U.S. singles describe themselves as very or somewhat romantic, and 73% believe media and pop culture set unrealistic expectations for what romantic love should look and feel like. Those two numbers sitting next to a 2.05 lifetime average suggest a real gap between what people expect passionate love to feel like on a recurring basis and how rarely it actually shows up.
That gap matters for anyone measuring their own life against it. If passionate love arrived on schedule every few years the way a lease renews, a stretch of years without it might reasonably read as something being wrong: with a person, a dating life, a capacity for feeling. But if the population-level average is roughly two episodes across seven or eight decades of adulthood, then long quiet stretches aren’t the exception. They’re the baseline. Someone who has felt it once and hasn’t again in a decade isn’t behind some invisible curve; they’re sitting inside the most common bracket in the entire dataset.
There’s also a case to be made that the rarity is the point rather than a disappointment. A feeling that showed up constantly would stop functioning as a signal. It’s precisely because passionate love is scarce, disruptive, and hard to summon on command that it carries the weight it does when it does arrive. The 14% who’ve never experienced it and the 30% who’ve experienced it exactly twice aren’t outliers on either end of a normal life. They’re most of the distribution. Passionate love isn’t a milestone you’re supposed to hit repeatedly to prove you’re living fully. It’s closer to weather than to routine, and its infrequency is exactly what makes it feel like weather worth remembering.
