Those of you who can access it, have a look. https://www.nytimes.com/2022/09/16/science/group-consensus-persuasion-brain-alignment.html?referringSource=articleShare
The bottomline is that they tested individuals in groups to see how much talking about something would sync their brains. They had them watch ambiguous movie scenes in a brain scanner separately. Then they’d have them talk about it in a group to put them in the scanner again watching the same scenes. Their responses were more in sync afterwards.
The article unpacks that more but that’s the main point.
I’d so love to be able to change two parameters:
- play with group size - what’s the biggest group we can still see this effect in?
- play with rounds instead of free-flow discussion. Maybe we can reach that effect faster with rounds?
