What makes someone utterly irresistible? Is it that infectious smile, how they laugh at your worst jokes, or how they listen intently when you’re venting about your day? Attraction is a fascinating blend of biology, psychology, and a dash of mystery. While we often think love is all about the heart, there’s a lot more happening behind the scenes than we might realise.

The Initial Spark: Chemistry or Just Good Timing?

We’ve all felt it—that spark, that fluttery feeling in your stomach when you first meet someone who catches your eye. It’s easy to chalk it up to chemistry, and science actually backs this up, at least to some extent. When we encounter someone we’re attracted to, our brains release a surge of dopamine—the “feel-good” hormone. This explains that immediate, almost electric connection we sometimes feel, as if our brain is rewarding us for spotting a potential match.

But here’s the kicker: timing can be just as crucial. The setting, your mood, and even how your day has gone can all influence whether someone strikes you as attractive or not. So, while the dopamine rush is real, the circumstances play a role too. But what happens when the initial spark fades? What sustains that attraction?

Familiarity Breeds Content

You’ve probably heard the saying “familiarity breeds contempt,” but when it comes to attraction, it’s often the opposite. Psychologist Robert Zajonc introduced the “mere exposure effect,” a concept that suggests we develop a preference for things—or people—simply because we’re familiar with them. This might explain why office romances are so common; spending a lot of time with someone can make them more attractive, even if they didn’t initially stand out.

In a classic study from the 1990s, researchers discovered that people rated faces as more attractive the more often they saw them. It’s like that quirky laugh your friend has—at first, it might have been annoying, but over time, it becomes endearing. The more familiar we become with someone, the more their hidden charms start to shine, deepening our attraction.

Opposites Attract? Not So Fast

The idea that opposites attract is one of those romantic myths that sounds great but doesn’t hold up well under scrutiny. While complementary traits—like one partner being outgoing and the other more introverted—can create a balanced dynamic, research shows we’re generally drawn to people who share our values, beliefs, and even habits.

A recent study found that people are more likely to be attracted to those who are similar to them in terms of attitudes, values, and activity levels. It makes sense; building a life with someone who shares your worldview is a lot easier. Whether it’s a mutual love for spontaneous road trips or a shared disdain for pineapple on pizza, these commonalities help forge a deeper connection.

But here’s where it gets interesting: it’s not about finding your carbon copy. The key is to find someone who aligns with your core values but brings enough differences to keep things exciting.

The Role of Physical Appearance: More Than Meets the Eye

Let’s address the elephant in the room—physical appearance. While we all know looks aren’t everything, they do play a role, especially in the early stages of attraction. It’s often what initially draws us in. However, as the emotional and intellectual connections deepen, the emphasis on looks tends to fade. That’s why you might find yourself falling for someone who isn’t your “type” after spending more time with them.

The Power of a Good Sense of Humour

If there’s one trait that consistently tops the list of desirable qualities in a partner, it’s a good sense of humour. Humour is more than just about making each other laugh; it’s a way to connect on a deeper level. Sharing a laugh isn’t just fun—it creates a bond.

Interestingly, humour is often linked to intelligence and creativity, which might explain why it’s so universally attractive. A good sense of humour signals that the person is sharp, resourceful, and fun to be around.

Emotional Intelligence: The Silent Attraction

While physical appearance and humour are easy to spot, emotional intelligence (EQ) often flies under the radar but plays a crucial role in attraction. EQ is the ability to recognise, understand, and manage our own emotions while being attuned to the emotions of others. People with high EQ are empathetic, great listeners, and skilled at navigating the ups and downs of relationships.

It’s no wonder that emotional intelligence is a major factor in long-term attraction. A partner who understands your feelings offers support and communicates effectively is a keeper.

So, what really draws us to our partners? Is it their looks, humour, values, or some magical concoction of all these? Science gives us clues, but love remains an art as much as it is a science. And maybe that’s for the best—after all, would it be half as exciting if we had it all figured out?
