Why strangers can feel like old friends

Freud thought the person who feels instantly familiar is someone your unconscious already knows.

In brief

Freud thought the person who feels instantly familiar is someone your unconscious already knows. That flash of familiarity is usually recognition, not fate, and a real connection comes from making the other person feel valued. Originally reported by Psychologies.

The stranger you already know

Pourquoi certaines personnes nous semblent étrangement familières dès la première rencontre : Freud avait une théorie

You meet someone once and feel like you have known them for years. It happens often enough that psychologists and philosophers have both taken a run at explaining it.

Freud named the feeling

Freud named the feeling

In his 1919 essay The Uncanny, Freud studied moments when something feels strange and oddly familiar at the same time. A gesture, a phrase, a way of moving can set it off.

Buried, not new

The Freud Museum puts it plainly: the uncanny is not really new, it was familiar in the mind before repression pushed it out of reach. The person in front of you pulls it back up.

“familiar dans l'esprit avant de devenir étranger à la suite du refoulement”

No one is random

Freud went further and claimed our attractions are pre-written. A face, an expression, a tone of voice matches something already filed away in the unconscious.

“Nous ne rencontrons que ceux qui existent déjà dans notre subconscient.”

Or just repeat exposure

Modern psychology offers a flatter answer. A 2017 study confirmed the mere exposure effect: the more we see something, the more we like it, until too much repetition wears the appeal back down.

Skip the impressive part

Psychologist Jeffrey Bernstein says lasting first impressions come from valuing the other person, not dazzling them. Ask what they care about outside work and the first thirty seconds do real work.

“la clé pour faire une première impression durable n'est pas d'impressionner, mais de valoriser l'autre”

The main idea

That flash of familiarity is usually recognition, not fate, and a real connection comes from making the other person feel valued.
