I feel like everyone relates to this in one way or another. There are always situations where anyone is an outlier.
Working on a project? The one person who either does all the work or does no work is the outlier.
Three people in the same room? The one person not talking.
It seems like all the situations will result in one outlier. It shouldn’t be like that, but changing it is difficult. Trying to help with the project or get them to help will result in anger and frustration. Trying to keep a completely even conversation going is difficult. Someone always says less, and less, and less, until they don’t talk at all. Then there’s the awkward moment they are listening but don’t think they can talk.
Quite a predicament for human society.
