Tinder Made Campus Hookups More Common. It Didn't Make More Relationships.

A natural experiment, not another survey

Every few months another headline says dating apps are quietly wrecking a generation. A new paper in the American Economic Journal: Applied Economics took a much harder look at that claim, using one of the biggest natural experiments available: Tinder's own rollout across American college campuses.

Economists Berkeren Büyükeren, Alexey Makarin, and Heyu Xiong didn't just survey people and ask if dating apps made them happy, which is how a lot of this research gets done and why it's so easy to mix up correlation with causation. People who are already isolated or unhappy might be more likely to download a dating app in the first place, which makes any link to poor mental health hard to interpret. Instead, the study exploited a quirk of history: when Tinder launched in 2012, it grew city by city and campus by campus, and its earliest marketing push specifically targeted Greek organizations. That staggered, uneven rollout let the researchers compare outcomes for similar students before and after Tinder reached their campus, using more than 1.1 million undergraduate survey responses collected between 2008 and 2019, plus over 700,000 college newspaper articles as a secondary data source.

More hookups, not more relationships

The headline result: once Tinder arrived, sexual activity rose sharply among Greek-affiliated students, who were several percentage points more likely to report having had sex in the past month. That effect held up for years afterward. What didn't move was the rate of students forming stable, long-term relationships or moving in together. The app changed how students met and what happened next, but it didn't translate into more committed pairings. If your mental model is "dating apps are just a faster way to find a partner," this data says otherwise, at least for this population.

The paper also documents a "superstar effect" familiar to anyone who's used Tinder: a small share of users, disproportionately men, captured an outsized share of matches. Dating outcome inequality widened after the app's arrival, meaning the gap between the most and least successful users grew larger, not smaller.

The costs were real, but so was a counterintuitive upside

This isn't a feel-good story about frictionless romance. Reports of sexual assault rose by about 2 percentage points against a roughly 9% baseline, a meaningful jump. Rates of STI testing and diagnoses, including chlamydia, also increased, though the authors are careful to note that some of that rise likely reflects more people getting tested rather than a purely mechanical increase in infections.

What's genuinely surprising is what happened to mental health. Average wellbeing scores didn't decline after Tinder's arrival, and Greek-affiliated women specifically showed small improvements, including lower rates of severe depression, self-harm, and disordered eating. The authors don't claim to know exactly why, but it complicates the tidy story that swiping is inherently corrosive to how people feel about themselves.

What this does and doesn't tell you

A few caveats worth sitting with. This is a study of American college students between 2008 and 2019, a specific population at a specific moment when Tinder itself was new and its user base skewed young. It says less about how dating apps function today, at scale, across all age groups, or now that swiping culture is over a decade old and users have adapted to it. And "didn't worsen mental health on average" isn't the same as "good for everyone." Averages can hide people who were genuinely harmed.

What the study does well is separate two things that get flattened together in most dating app coverage: behavior change and wellbeing change. Tinder clearly changed what people did. It didn't clearly change how bad they felt, at least in this population and this window.

If you're curious how your own dating app use compares to your intentions, that's exactly the kind of thing RizzStats is built to show. Upload your Tinder or Hinge export and it'll break down your match rate, reply rate, and activity over time, so you can see your own patterns instead of guessing from a headline.
