I wonder if the participants can't hear each other if they live in the apartments right next to each other…
For example, one of them was so happy and then started screaming. And if you're a little smart, you can figure out whether the person is fake or not…
Personally, I think that's posed. As I said, it doesn't make sense to me and the walls in America are all too well known for not being soundproof.
By the way, I don't think that a normal person is that open-minded, in the first episode they are really active in front of the camera, etc. But that's just my opinion.
And because of this "game system" as if they have created their own program and an AI, they speak to them completely individually.
