A Little Wanderlust… Yep, There’s a Genetic Reason We Love to Travel

Last updated on October 14, 2026 by Shannon

I was paging through National Geographic magazines and dreaming of elsewhere long before I ever bought a plane ticket. I declared myself a linguistics major for one brief semester in college because I loved the way language shapes how people think, and a decade before I ever heard the term “digital nomad,” a conversation with my dad planted the idea that working while traveling the world was even possible. None of that explains why I deeply loved moving around the world—always visiting new places and eventually settling in Spain in 2018—while most people I grew up with stayed close to home.

So when I came across the research on a genetic trait tied to wanderlust, I wanted to know more—and also wanted to know how much of it holds up.

What is the Wanderlust Gene?

It’s called DRD4-7R, and it’s a variant of a dopamine receptor gene. Researches have loosely tied this gene to traits like novelty-seeking, risk-taking, and curiosity about the world. The travel aspect: Those with the gene may crave new experiences more intensely than others.

Roughly 20% of people carry this gene variant on average—though that figure is only useful as a rough global baseline. This means that while some people (me) have an insatiable desire to travel, others are perfectly content staying close to home (my bestie).

Of course, this isn’t a full explanation for anyone’s wanderlust. But it does make me wonder if a desire to roam is wired into our biology. The frequency actually swings wildly by population—far more than a single global average suggests. Migratory and historically nomadic peoples tend to carry a higher proportion of the DRD4-7R variant than populations that settled and stayed put.

Here’s where I have to correct something I got wrong the first time I wrote this: the research doesn’t point to Europeans specifically. The actual pattern researchers have found is a correlation between 7R frequency and migratory distance from humanity’s origin point in East Africa—it shows up more in populations with a long history of migration or a nomadic, pastoralist lifestyle, not in any one ethnicity. By that logic, some of the highest frequencies recorded are in Indigenous populations of the Americas, not in Europe.

I’ll also say the “wanderlust gene” label oversells what the science actually shows. DRD4-7R is tied to novelty-seeking broadly—it shows up in research on ADHD and risk-taking too—and no single gene cleanly explains a behavior as complicated as why someone sells their stuff and buys a one-way ticket. It’s a real, interesting correlation. It’s not a diagnosis, and it’s not destiny.

Why It Resonated With Me

Something clicked when I read about the gene, because it matched a pattern I’d lived rather than explained one. I researched going to college out of state as a teenager but couldn’t pass up a full-ride to a state school, moved to LA the week I graduated, and then left the U.S. in 2008 with a one-way ticket and no real plan to come back. I told myself it would be a year-long break. Decades later, travel is still at the core of how I live.

Whatever the science ultimately does or doesn’t prove, I fall into the category of people with a deep-seated desire to immerse in new cultures, try new foods, and meet new people—and that desire has outlasted every “this is just a phase” prediction people made about me in my twenties.

Signs You Have the Wanderlust Gene

Some have suggested that the gene may be responsible for the rise of tourism and travel as a global industry—as travel has become increasingly accessible and affordable, more people are seeking out new experiences and adventure.

Genetic testing to confirm you actually carry the variant runs about $50. Cheaper and more fun: look for these patterns in your own travel habits instead.

None of these habits prove anything about your genetics. But if more than a couple sound like you, you already know which category you’re in.

• You trace journeys on maps, not just itineraries. I’m just as likely to hang a beautiful map on my wall as I am travel photos. Maps hold stories, and the world’s too big to tell just one story.
• You speak the language of many lands. Fluency isn’t the goal—connection is. I always learn “hello,” “thank you,” and “goodbye,” no matter how obscure the language. In Nepal, my hiking guide on the Annapurna circuit taught me folk songs just to help me survive the climbs—I still know them 15 years later.

• Your playlist is a passport. Every song takes you back—to Fraser Island, where we road-tripped and traded Spotify DJ duties, or to that one Danish track I still associate with couchsurfing in Melbourne.
• You taste the world, even when it’s tricky. Being a vegetarian in Vietnam was no small feat, but food is culture—so I figured it out. I’ve eaten street food in Myanmar without knowing a word of the language and devoured bureks in Bosnia with sour yogurt on the side. If it’s edible and local, I’m trying it.

• You find magic in airports. I don’t run to the gate—I arrive hours early. Coffee in hand, I dive into research, books, or random convos with strangers. Airports are my jam.
• You travel with questions, not just cameras. When I landed in Tokyo, everything felt unfamiliar — and I loved it. I wasn’t just sightseeing, I was decoding culture. Why do homes in Burano shine in neon colors? Why are hammams central to Turkish life? If that sounds like your kind of trip, you know the feeling.

• You travel as a force for good. In Kenya, I stayed with the Maji Moto Cultural Camp—a social enterprise fighting FGM and supporting girls’ education. Travel like that doesn’t just satisfy wanderlust, it helps build a better world.

Genetics Isn’t the Whole Story

Whether or not you believe in the wanderlust gene, it’s clear some people feel more comfortable staying in one spot, while others thrive on the road. Maybe it’s a mix of biology, upbringing, and lived experience.

Some travelers are chasing novelty. Others are healing, searching, learning, or connecting. Whatever drives us, that curiosity—that urge to see more—is powerful.

How the Gene Influences Behavior

People with the wanderlust gene may be more likely to engage in travel and exploration, but genetics alone does not determine behavior. Environmental factors, such as upbringing, life experiences, and your eventual life partner or close friends also play a significant role in shaping behavior.

“One of the core five personality traits many people identify across the world is openness to experience,” says Adam Galinksy of Columbia Business School. “And that is both a trait that increases the probability people are likely to go abroad and the likelihood of whether they’ll benefit from those experiences.”

The fact is, the presence of the wanderlust gene may make you more susceptible to the influence of environmental factors that encourage travel and exploration. If your parents exposed you to travel young, you could have caught the travel bug from them.

Or if your college roommate saves every penny to travel—or convinces you to study abroad, these are all factors that could make someone with the wanderlust gene fall in love with traveling.
