Oxymoronic paradoxes arise from theorizing simultaneously about people and their own theories about people. For example: only inferior/superior/ people (don't) believe in the existence of inferior and superior people. If someone believes everyone is good, they have no way to tell that someone is bad for believing that some people are bad, and if the latter person has no other way to comprehend incorrectness, except through personification, it becomes (seemingly) impossible to convey meaning to them.
If a scientist studies people and finds out that some of them are indeed genetically redundant, if that's even logically possible, but then he also finds out he belongs to the same misfortunate group himself. Would the scientist then conclude that his own conclusion must have been flawed, because he's one of the flawed-thinking people?
