I’m trying to find the study you mention, but a huge caveat IIRC is that these were not people who knew each other, but a random sample of experimental participants (likely college students.) I’d expect this effect to be less pronounced among a group of peers who sees how the others work on a regular basis. Still there, but a lot less pronounced. Behavioral psychologists don’t tend to have access to a group of peers like that, though.
