Chemistry vs Real Compatibility

Something I’ve noticed again and again in my work — both during my years in matchmaking in London and now in therapeutic relationship work — is how easily we mistake emotional intensity for compatibility.

When something feels very strong very quickly, we often assume:

“This must be special.”

The chemistry is powerful.The attraction feels magnetic.The conversations feel electric.

But intensity and compatibility are not the same thing.

Very often what we call chemistry is actually our nervous system recognising something familiar.

Attachment research — beginning with the work of John Bowlby and later expanded by researchers like Sue Johnson — shows that our early relational experiences shape how we experience closeness, attraction and safety in relationships.

In other words, our nervous system doesn’t automatically look for what is healthiest.

It often looks for what is familiar.

And familiar can sometimes include things like:

• emotional unpredictability

• push–pull dynamics

• or the subtle tension of not quite knowing where you stand

Interestingly, psychology research also shows that familiarity itself can increase attraction — something known as the mere exposure effect (Zajonc, 1968).

So sometimes what we interpret as chemistry may actually be nervous system activation, not compatibility.

Real compatibility tends to feel different.There may still be attraction and spark — but there is also:

• emotional safety

• consistency

• responsiveness

• clarity about where you stand

Less rollercoaster.More grounded connection.

And paradoxically, this kind of connection can sometimes feel almost too calm at first — simply because many of us are more used to intensity than stability.

But that calm is often exactly where real intimacy has the space to grow.
