This phrase exists to explain how someone gained their knowledge. For example, someone may know about institutionalized discrimination because they themselves were a victim (a lived experience) or because they read about it in the local newspaper. As a community manager, it is important to recognize the difference between these ways of knowing and the impact they have upon the knower.
