Interpersonal Synchrony (The Click Effect)
book · Why We Click: The Emerging Science of Interpersonal Synchrony (2026)
Interpersonal synchrony is the measurable alignment of physiological and behavioral rhythms between people during social interaction, underlying feelings of connection and rapport.
Core Concepts
The Problem
Why do some interactions feel instantly comfortable while others feel awkward?
The Claim
Synchrony, measurable via breathing, heart rate, and neural activity, is the hidden mechanism behind social chemistry.
Key Evidence
- •Research in interpersonal synchrony shows that conversational partners unconsciously coordinate movements and physiological states, and higher synchrony predicts greater cooperation and liking.
Practical Implication
Understanding synchrony can improve first impressions, team cohesion, and relationship formation.
Nuance & Limits
Synchrony is not just about mimicry; it's a two-way process that requires mutual attention and responsiveness.
