Do you find it easy to keep conversations with friends interesting?

A Dartmouth College study published in Science Advances analyzed more than 1,000 conversations between strangers and found that more pink noise in a chat predicted greater enjoyment, a desire to keep talking and a stronger sense of connection. The same pattern held in conversations between friends and predicted which speed-dating pairs met again.

Why it matters

The findings suggest that the rhythm of back-and-forth exchange, not just the content of what people say, may shape whether a conversation feels good and leads to a lasting connection. For people building new friendships or dating, it offers a measurable way to think about why some talks click.

The study analyzed more than 1,000 conversations between strangers, and researchers used the AI program MPNet to score every conversational turn on 768 criteria. Pink noise falls between white noise and red noise on the conversational scale, and the source does not specify effect sizes.

The players

Dartmouth College

Dartmouth College is a private Ivy League research university in Hanover, New Hampshire, where the study was conducted.

The details

Researchers measured how conversations ebbed and flowed over time and found that pinker exchanges were more enjoyable and felt more connecting to participants. Pink noise also predicted which speed-dating pairs chose to meet for a second date, and the pattern appeared among friends discussing formative experiences.

Over the first 50 episodes of a two-host podcast, the pinkiness of the hosts' conversations increased.

Season Trajectory

This study extends conversation analysis, the research tradition that examines turn-taking in everyday talk, by applying an AI model to measure conversational rhythm across more than 1,000 exchanges. It positions the rhythm of exchange as a measurable factor in how people connect.

The findings suggest that noticing whether a conversation has a balanced back-and-forth rhythm could help people gauge whether a new connection is taking hold. Readers building friendships or dating can use this as a simple observation during everyday talks.

The takeaway

Pay attention to the rhythm of back-and-forth exchange in your conversations, since balanced turn-taking may signal the enjoyment and connection that make a relationship grow.
