Why person-to-person conversation still wins

By Quell Media · November 5, 2026 · 5 min read

We live in the most connected era in history, and somehow it's never been harder to actually reach someone. Inboxes are full, feeds are endless, and a growing share of what we see wasn't made by a person at all. In that environment, a real conversation between two real people stands out more than it ever has.

Face to face is dramatically more persuasive

Researchers Mahdi Roghanizad and Vanessa Bohns ran a simple experiment. Participants asked strangers to fill out a short survey. Half asked in person and half asked by email, using the same script. The in-person requests were about 34 times more effective than the emails.1 The people asking expected the two to work about the same. They badly underestimated how much being there in person matters.

34×more effective: in-person requests vs. email in Roghanizad & Bohns' study.1

It was a small study about a simple request, so we wouldn't stretch the exact number too far. The direction is hard to argue with, though: when people can see a face, hear a voice and pick up on tone, they respond differently.

People trust people they know

Nielsen has asked people for years which forms of advertising they trust. Recommendations from people they know consistently top the list. In Nielsen's 2021 U.S. study, 89% said they trust recommendations from people they know, the most trusted channel measured.2

A customer testimonial isn't quite a recommendation from a friend. But it's the closest thing marketing has to one: a neighbor, a regular, someone who looks like the viewer, vouching in their own words.

How we run our interviews

We don't hand anyone a script. We ask real questions and let people answer the way they'd tell a friend:

Then we get out of the way. The best moments come from people talking, not performing.
