Tipping point (sociology)
In sociology, a tipping point is a point in time when a group—or many group members—rapidly and dramatically changes its behavior by widely adopting a previously rare practice. == History == The phrase was first used in sociology by Morton Grodzins when he adopted the phrase from physics where it referred to the adding a small amount of weight to a balanced object until the additional weight caused the object to suddenly and completely topple, or tip.
