What the recording showed
Participants were simply asked to meet and talk. No tasks, no stakes. After the conversation, each person watched the video and was asked to mark the moments when they had not been completely truthful. People were genuinely surprised by their own results.
About this many out of 10 people lied at least once in 10 minutes
The group was small, and participants identified the lies themselves, so the figure is not exact. But the pattern is also confirmed by other studies: small lies are woven into ordinary conversation far more deeply than we tend to think.
What people actually lie about
Almost none of these lies are about facts. They are about relationships. Someone exaggerates their interest, agrees with something they disagree with, claims a little more experience or makes themselves seem a little less tired. The goal is always the same: to keep the conversation smooth.
I love events like this.
Me too! Great atmosphere.
By the way, I read your article. Really interesting.
Thanks! I was actually planning to rewrite it.
Let's definitely talk sometime this week.
Every line here could be untrue, and none of them feels deceptive. It's social lubricant: it reduces friction and lets two strangers part without awkwardness. You would hesitate to call it lying, even though technically that's what it is.
Why we don't notice
These phrases are spoken automatically, without an internal decision to lie. A person isn't weighing truth against falsehood; they are choosing an appropriate response. So when they watch the recording, their own words sound like someone else's, and they often don't immediately agree that they had been untruthful.
That leads to an important point about detecting lies. Since small lies sound completely natural and aren't accompanied by anxiety, looking for signs of nervousness is pointless. Someone who is lying about something important and has something at stake gets nervous, not someone who praised another person's article.
Why might you not notice a small lie in a conversation?
