Eli Finkel & Paul Eastwick on What Love Science Reveals

What love science reveals often challenges everything we’ve been taught by pop culture. In this thought-provoking episode of Passion Struck, John R. Miles sits down with Dr. Eli Finkel and Dr. Paul Eastwick—two of the world’s leading researchers on relationships—to dissect the gulf between Hollywood’s version of love and what science actually shows makes relationships thrive.

From rom-com fantasies to TikTok soundbites about soulmates and twin flames, we’re surrounded by narratives suggesting love should be effortless, magical, or instant. But Finkel and Eastwick argue that these myths can quietly sabotage our ability to form meaningful, lasting bonds. Instead, their decades of research point to a more grounded—and more empowering—truth: real love isn’t found; it’s built.

Together, they explore the difference between “destiny beliefs” (the idea that you’re either meant to be or not) and “growth beliefs” (the idea that connection can be nurtured over time). Finkel’s research consistently finds that couples who embrace growth beliefs have more resilient and fulfilling relationships. In a world obsessed with perfection and instant chemistry, this conversation is a refreshing reminder that love is a process, not a prize.

How Real Love Works: The Science Behind Stronger Relationships

Forget the fireworks and fairytales—this episode explores what actually makes love last. Dr. Eli Finkel and Dr. Paul Eastwick share findings from decades of relationship research, revealing why the most resilient partnerships aren’t about finding “the one,” but growing together through effort and adaptability.

They dive into the psychology of attraction, the myth of perfect compatibility, and how culture shapes our ideas of romance—for better or worse. Through frameworks like destiny vs. growth beliefs, they challenge us to rethink the way we define love and success in relationships.

This conversation builds on the same mission that fuels their podcast Love Factually: to bring scientific truth into the stories we tell about love—and help us write better ones for ourselves.

In This Episode With Eli Finkel and Paul Eastwick, You’ll Learn:

• Compatibility, decoded: Why “perfect matches” matter less than the skills partners develop together.
• Soulmate myth-busting: How rigid “meant to be” beliefs quietly erode resilience when trouble hits.
• Love as co-creation: Practical steps couples can take to build, not find, lasting intimacy.
• Modern marriage peaks: What makes today’s best unions the strongest in human history—and why they’re also the most fragile.
• Science-based “lovehacks”: Research-tested micro-behaviors that boost satisfaction in minutes a week.

WHY IS THIS EPISODE WITH ELI AND PAUL A MUST-LISTEN?

Most relationship advice is recycled wisdom dressed up as revelation. This episode delivers something rarer: insights forged in the lab and tested in real lives. You’ll walk away with a clearer understanding of what actually predicts lasting happiness, plus concrete strategies you can implement tonight. Whether you’re single, dating, or decades into commitment, the evidence-driven perspective offered here can transform how you approach love and partnership.

What “The All-or-Nothing Marriage” Teaches Us About Love Today

In this episode, Dr. Eli Finkel shares powerful insights that expand on the ideas from his groundbreaking book The All-or-Nothing Marriage: How the Best Marriages Work. The book argues that the purpose of marriage has evolved dramatically over time, from survival and companionship to a modern pursuit of self-growth, emotional fulfillment, and shared purpose. And while that shift has created the potential for deeper, more meaningful partnerships, it also raises the bar—and the pressure.

Throughout the conversation, Eli explains how this modern model of marriage can lead to the most rewarding relationships in history—but only if couples have the emotional tools, communication habits, and support systems to sustain it. He and Paul explore what it takes to build that kind of connection and why many couples struggle when they expect marriage to deliver personal transformation without shared effort.

The themes of The All-or-Nothing Marriage serve as a foundation for the episode’s biggest takeaway: great relationships aren’t found—they’re co-created. And understanding how to navigate this new landscape of love is essential for anyone looking to thrive in it.
