I remember seeing an amazingly visualised website that was showing a result of an experiment that made people talk with strangers, and it had mostly positive result for most participants, even if they felt uncomfortable or scared at the beginning, and it had gopd results even if people with differenting opinions about i.e politics talked. Unfortunately I can't seem to find it again.

I don't know if it was part of the same research, but there was also a part where they had people talk to strangers on a bus ride, and it also went well in most cases.

Sp, talking to strangers is mostly recommended and should be mostly positive, at least statiatically speaking.
