Men Fall in Love Faster Than Women, Scientific Research Says

Estimated read time 6 min read

May 5, 2025 – Forget everything you learned from Sleepless in Seattle or The Notebook. A new study from the Australian National University (ANU) has dropped a plot twist: men fall in love faster than women, and they’re doing it with the enthusiasm of a puppy chasing a tennis ball.

So, grab your popcorn, because this research is rewriting the rules of romance with a side of statistical sass and a sprinkle of evolutionary humor.

The Science of Speedy Love

In a study published in Biology of Sex Differences in 2025, ANU researchers surveyed 808 young adults aged 18-25 across 33 countries, from the US to South Africa. The findings? Men are out here catching feelings in record time, falling in love about a month earlier than women—0.98 months (roughly four weeks) into a relationship, compared to women’s 1.92 months.

That’s right, guys are basically saying “I love you” while women are still deciding if they vibe with their date’s Spotify playlist.

But it’s not just speed—men also fall in love more often, averaging 2.6 romantic dives compared to women’s 2.3. They’re also more likely to fall before the relationship is official (30% of men vs. 20% of women), making them the hopeless romantics of the dating world.

Men Fall in Love Faster

Women, however, when they do fall, bring the intensity, obsessing more about their partner and showing stronger commitment. It’s like men are the opening act, and women are the headliner who steals the show.

Lead researcher Adam Bode suggests this male haste might come from a need to signal commitment early. “Men are evolutionarily wired to say, ‘Pick me! I’m ready!’ while women are like, ‘Hold up, I need to see your five-year plan,’” Bode might quip if he moonlighted as a stand-up comic.

The study points to biology: men, with less reproductive risk, can afford to fall fast, while women, historically choosier, take their time to pick a winner.

Debunking the Rom-Com Myth

For decades, Hollywood has fed us the idea that women are the ones doodling hearts in their diaries, while men play it cool. But this study, backed by earlier research like a 2017 Journal of Social Psychology survey of 172 college students, says men are the real romantics.

They’re more likely to believe in love at first sight (48% of men vs. 28% of women, per a 2013 US study) and to drop the “L-word” first.

Psychologist Marissa Harrison, co-author of the 2017 study, told Broadly that women’s slower pace is strategic: “Men have a daily sperm factory, so they’re ready to commit by the second date. Women, with a limited egg supply, are basically auditioning for The Bachelor.”

Okay, she didn’t say that exactly, but the point stands: women’s caution challenges the stereotype that they’re love’s biggest dreamers. Instead, they’re the ones running a full compatibility scan.

And let’s talk about the comedy of it all. Men falling fast can lead to some cringe-worthy moments, like confessing love on date three only to get a “Wow, that’s… sweet” in response. As one X post put it, “Men fall in love faster… even if they don’t text back.” Talk about mixed signals!

Why Are Guys So Quick on the Draw?

So, what’s got men tripping over their hearts? The ANU study suggests it’s partly evolutionary—men needed to secure a mate quickly to keep the species going. But social pressures play a role too. Men are often expected to take the lead, from asking someone out to declaring love.

Dating expert James Preece told Bustle that men can “fall in lust” based on looks alone, mistaking a crush for the real deal. Picture a guy thinking, “She’s hot, this must be love!” while his date’s like, “Sir, you just met me.”

A 2010 Evolutionary Psychology study adds that men who overestimate a woman’s interest or prioritize physical beauty fall faster. So, if a guy misreads a polite smile as “marry me,” he’s already booking the honeymoon. Women, however, are more likely to fall when there’s a strong emotional or sexual connection, making their love a slower burn.

The ANU study also found that in countries with higher gender equality, both genders fall in love less often and with less obsession. Maybe when everyone’s on equal ground, love feels less like a soap opera and more like a chill Netflix series.

Women Love Deeper, Men Bounce Back

Here’s where it gets interesting: while men fall faster, women fall harder. The ANU data shows women think about their partners more obsessively and feel love more intensely. A Sex Roles study adds that women are better at spotting relationship flaws and handling rejection, meaning they’re less likely to waste time on a dud.

Men, on the other hand, might pine over unrequited love or jump to the next crush like they’re swiping on Tinder.

This sets up some classic rom-com scenarios. Imagine a guy pouring his heart out, only for his partner to say, “I need six more weeks to process this.” As Vice noted, men’s quick love declarations might be their way of staking a claim, but it doesn’t always mean they’re ready for the long haul.

What’s Love Got to Do With It?

This research isn’t just a quirky headline—it’s a wake-up call for how we think about love and gender. Men aren’t the commitment-shy bros of How I Met Your Mother fame, and women aren’t the starry-eyed heroines of Twilight. Instead, love is a wild ride where men might jump in first, but women bring the depth that keeps it going.

For the guys out there, this study’s a reminder: it’s okay to feel the butterflies, but maybe check if your crush is on the same page before renting a U-Haul. And for the ladies, take your time—your heart’s running a marathon, not a sprint. As one X user hilariously noted, “Men fall in love twice as fast as women… and still forget to text back.”

Whether you’re a hopeless romantic or a skeptic, this study proves love’s a universal language with some surprising accents. So, next time you’re on a date, keep an eye out for that guy who’s already naming your future dog. He’s not crazy—he’s just following science.
