“I know this isn’t right, but I can’t seem to walk away.”

Have you ever listened to a friend describe a relationship and wondered how they could possibly miss what seems so obvious?

Maybe you’ve watched a successful executive stay with a partner who repeatedly disappoints them. Perhaps you’ve seen a brilliant academic ignore glaring incompatibilities. Or maybe, if you’re being honest, you’ve looked back at your own romantic history and asked yourself:

“What was I thinking?”

The uncomfortable truth is that intelligence and good judgment do not always travel together when attraction enters the room.

In fact, some of the smartest people make some of the most puzzling relationship decisions.

Not because they lack insight. Not because they are weak. But because attraction changes how the brain processes reality.

This week, as we explore the fascinating gap between what we say we believe and what we actually do when emotions are involved, it is worth examining one of the most powerful forces shaping human behaviour: attraction.

Attraction Is Not Just a Feeling. It Is a Neurochemical Event.

Many people think attraction is simply an emotion.

Psychologists and neuroscientists would disagree though.

When attraction begins, the brain activates a complex reward network involving neurotransmitters such as dopamine. Contrary to popular belief, dopamine is not merely the “pleasure chemical.” Neuroscientists describe it more accurately as a motivation and anticipation chemical. It drives pursuit. It captures attention. It tells the brain:

“This matters. Pay attention.”

The work of neuroscientist Helen Fisher has shown that romantic attraction activates many of the same reward pathways associated with motivation, goal pursuit, and reinforcement. Attraction, therefore, is not passive. It is a state of heightened focus.

This helps explain why people can become preoccupied with someone they barely know.

The brain is not necessarily evaluating compatibility. It is assigning significance. And significance often feels remarkably similar to certainty.

Why Novelty Feels So Powerful

Humans are naturally drawn to novelty.

New experiences stimulate curiosity and activate reward systems. A new relationship offers uncertainty, anticipation, and possibility which are all highly stimulating experiences for the brain. The philosopher Blaise Pascal once observed that much of human behaviour is driven by our inability to remain content with what already is. We are drawn toward possibility, mystery, and the promise of something different.

This may help explain why people sometimes abandon stable relationships for exciting but uncertain ones. The excitement itself becomes rewarding. And this is not necessarily because the new person is better. But because novelty feels meaningful. Essentially, the brain often mistakes intensity for importance.

Attraction Changes What Your Brain Notices

One of the most fascinating aspects of attraction is selective attention. When we become emotionally invested in someone, our attention shifts. We notice the qualities that reinforce our feelings. We pay less attention to information that challenges them.

A friend may point out concerning behaviour. Family members may express reservations. Even our own instincts may raise questions. Yet somehow those concerns feel less urgent than they would under different circumstances.

Attraction changes what your brain notices and what it politely edits out. The information does not disappear. It simply receives less psychological weight.

Psychologist Daniel Kahneman described how human beings often rely on cognitive shortcuts and biases when making decisions. We like to think we evaluate information objectively, but our minds are constantly filtering reality through emotion, expectation, and prior beliefs.

Relationships are no exception.

The Trap of Idealization

Attraction often gives rise to idealization. This is the tendency to see people not as they are but as we hope they might be. We begin filling in the gaps.

Potential becomes character. Promises become evidence. Chemistry becomes compatibility.

The psychoanalyst Erich Fromm argued that mature love requires seeing another person realistically rather than projecting fantasies onto them. Yet in the early stages of attraction, realism is often the first casualty.

We are not merely relating to the person in front of us. We are relating to our interpretation of them. And those interpretations can be remarkably persuasive.

Emotional Reinforcement Loops: The Relationship Slot Machine

One of the most overlooked aspects of attraction is intermittent reinforcement.

Behavioural psychologists have long understood that unpredictable rewards are among the most powerful drivers of human behaviour. Think of a slot machine. You do not win every time.

But the uncertainty keeps you engaged. Relationships can operate similarly.

A text message arrives.

You feel excited.

Attention is given. You feel valued.

Then the person becomes distant.

You miss them.

Then they reappear.

You feel relief.

The cycle continues.

The unpredictability itself becomes emotionally addictive. This is not necessarily a sign of love. It is often a sign that the brain has become highly responsive to intermittent rewards. What feels like profound connection may sometimes be a reinforcement loop.

Why Smart People Ignore Obvious Mismatches

This may be the most humbling lesson of all.

Highly intelligent people are not immune to emotional bias. In some cases, they are exceptionally skilled at rationalizing it. The social psychologist Leon Festinger introduced the concept of cognitive dissonance—the discomfort people experience when reality conflicts with their beliefs or choices.

When someone we care about behaves in ways that contradict our expectations, we face a choice. We can change our view of the person. Or we can change our explanation of their behaviour. Many people choose the second option.

Not because they are foolish. But because emotional investment makes objectivity difficult.

A missed commitment becomes stress.

Dishonesty becomes confusion.

Incompatibility becomes complexity.

A pattern becomes an exception.

Sometimes we do not change our standards. We change our explanations.

The Philosophical Problem of Love and Judgment

Philosophers have wrestled with this tension for centuries. Friedrich Nietzsche famously remarked that there is always some madness in love.

While perhaps overstated, the observation captures an enduring truth.

Love and attraction often ask us to tolerate ambiguity.

Judgment seeks clarity.

Attraction pulls us toward connection. Reason asks us to evaluate consequences. The challenge is not choosing one over the other. It is learning how to hold both simultaneously. The healthiest relationships are not built on attraction alone. They are actually built on attraction examined through the lens of awareness.

What Healthy Attraction Looks Like

Healthy attraction does not require ignoring reality. It allows room for curiosity. It permits admiration without blindness. It encourages emotional connection while remaining open to evidence.

Healthy attraction asks:

• How do I feel around this person?
• What patterns am I observing?
• Do their actions align with their words?
• Am I responding to who they are or who I hope they become?

These questions create space for both emotion and discernment.

Final Thoughts

One of the most humbling realities of being human is that none of us are as objective as we believe.

Attraction has a remarkable ability to influence attention, shape perception, reinforce emotional investment, and soften the significance of information that might otherwise concern us. The goal is not to become cynical. Nor is it to distrust attraction.

The goal is awareness. Because awareness allows us to appreciate attraction without surrendering judgment. Being intelligent does not immunize anyone against emotional bias. It simply means we may have more sophisticated ways of explaining it.
