While we usually think of good communication as staying 'on the same page,' this study of over 1,600 conversations found that the best talks actually require a phase of pulling apart. This 'differentiation' phase wasn't a sign of boredom; instead, conversations that followed this pattern resulted in a much stronger sense of shared connection between the speakers.
From the abstract
Conversations are dynamic systems of coordinated behavior. Utterances lengthen and shorten, emotions converge and diverge, topics stabilize and vary. Yet the temporal structure of these changes remains uncharacterized. We analyzed 1,656 extended conversations between strangers, using data across linguistic, facial, and acoustic communication channels. Our preregistered analyses tested the temporal trajectories of 27 conversational measures (e.g., utterance length, emotional similarity, topic per
