Why Repeated Contact Matters More Than Having Things in Common
Making and maintaining friendships as adults feels harder than during school days or early jobs. Despite countless social apps and networking opportunities, adult friendship—especially the kind that sticks—often eludes us. Why is that? And what truly helps people connect beyond polite small talk and passing acquaintances?
In this post, we’ll delve into the science behind repeated contact friendship, explain why shared hobbies or surface-level commonalities aren’t enough, and offer insights from small-group travel communities like Hero Traveler and Camp Social, who have nailed the art of shared time bonding. I’ll also briefly touch on how organizations like the U.S. Department of Health & Human Services (HHS) recognize these social dynamics in broader health frameworks.
The Adult Friendship Challenge: Why It’s Harder Than It Used to Be
Think back to elementary school or college — making friends often came down to who sat next to you, who showed up to the same class, or who you teamed up with for group projects. Physical proximity and shared environments made initial connections straightforward.
Fast forward to adulthood, and these natural social structures dissolve. For many adults, factors like:
- Busy lifestyles packed with work, errands, and family commitments
- Transactional work relationships focused on tasks, not emotional connections
- Shallow online ties that offer quantity but not depth
- Changing living situations and geographic mobility that disrupt community continuity
All this makes cultivating meaningful friendships feel like a high bar few can surmount.
Why You Should Shared Interests Alone Don’t Build Lasting Friendships
It’s tempting to think that having things in common—whether a hobby, political view, or taste in music—is the secret sauce for friendship. Though shared interests help break the ice, extensive research shows that this alone is insufficient for durable connections.
Professor Robert Feld, a prominent sociologist, coined the phrase “propinquity effect”—the tendency for people to become friends with those they see often rather than simply those who share traits. What matters more than common interests is the opportunity to interact repeatedly, allowing trust and vulnerability to grow over time.
The Science of Repeated Contact Friendship
Repeated contact involves multiple occasions of face-to-face or meaningful interaction. According to studies cited by the U.S. Department of Health & Human Services (HHS), these interactions cultivate emotional safety, foster empathy, and enable shared small moments that weave strong relational bonds.
Researchers emphasize that:
- Even casual repeated encounters—like seeing the same neighbors at the gym or coffee shop—can spark friendships if interaction is frequent and pleasant.
- Shared time spent through activities or challenges creates mutual memories, which bind people emotionally.
- True friendship formation is a gradual, iterative process — not an instant connection ignited by matching profiles or quick chats.
How Small Group Travel Enables Natural Repeated Contact
This is where the approach pioneered by companies like Hero Traveler and Camp Social shines. Small group travel experiences expertly create natural opportunities for shared time bonding.
Unlike conference networking or generic social events—often criticized for forced networking vibes—small group trips bring together 8-15 adults in immersive settings for multiple days in a row. This cancels out the “first night politeness” barrier and accelerates the transition from acquaintance to genuine connection.
Imagine waking up next to a new group of friends, joining them for hikes or meals, sharing stories around campfires, and discovering quirky commonalities along the way. During these repeated, relaxed interactions, conversations naturally deepen, and friendships start to take root.

What Makes This Work So Well?
- Intentional design: Trips are curated to optimize interaction time and minimize distractions.
- Shared experiences: Acts of navigating new places or challenges together create camaraderie.
- Ease and low pressure: Unlike work events or online chats, the social context is relaxed and enjoyable.
- Natural repeated contact: Multi-day duration ensures multiple shared moments to build trust and laughter.
Beyond Common Interests: Building Friendships that Thrive
The key takeaway is that while shared interests are valuable, they aren’t the primary ingredient for lasting friendships as adults.
Prioritizing repeated contact—a fundamental social ingredient—will deliver more consistent results in forming meaningful relationships. This is why groups that emphasize continued shared time and presence trump ones only focusing on surface similarities.
Don’t fall for vague promises of "life-changing friendships" without understanding the effort behind lasting connection. Instead, look for social environments facilitating repeated, natural, low-pressure interaction and shared experience, whether through travel, clubs, or community projects.
Social Health Matters for Everyone
Think about it: the u.s. Department of Health & Human Services (HHS) has clearly identified social connection as a social determinant of health. Loneliness and lack of friend networks impact mental and physical well-being significantly.
Recognizing this, programs and companies are shifting to models that support quality relationships through repeated social contact—not quick connections or checklists of common interests.
How to Get Started Building Friendships Through Repeated Contact
If you’re ready to invest in friendships that will stick, consider these steps:
- Join or create small groups around activities you enjoy that meet regularly.
- Consider small group travel with organizations like Hero Traveler or Camp Social to jumpstart natural shared time bonding.
- Prioritize face-to-face interaction over online-only connections whenever possible.
- Allow relationships time to grow through repeated contact instead of expecting instant chemistry.
- Keep your social calendar realistic and focused on quality over quantity.

Final Thoughts
Adult friendships don’t just happen because you like the same band or enjoy yoga. They require regular, meaningful contact and shared experiences that nurture trust and connection.
Small group travel companies like Hero Traveler and Camp Social exemplify this by designing environments where repeated contact comes naturally, helping strangers turn into friends who feel more like family.
So next time you’re looking to build friendships that last, think beyond common interests and focus on creating opportunities where you can regularly share time and moments with others. That’s the science-backed path to friendships that truly thrive.
