The Evaporative Cooling Effect - The Evaporative Cooling Effect is a term I learned from an excellent essay by Eliezer Yudowsky that describes a particular phenomena of group dynamics. It occurs when the most high value contributors to a community realize that the community is no longer serving their needs any more and so therefore, leave. When that happens, it drops the general quality of the community down such that the next most high value contributors now find the community underwhelming. Each layer of disappearances slowly reduces the average quality of the group until such a point that you reach the people who are so unskilled-and-unaware of it that they’re unable to tell that they’re part of a mediocre group.
