This study looks at dehumanization, how people treat each other like they're less than human. Instead of just focusing on the one being dehumanized or the one doing the dehumanizing, the researchers consider both sides. They found that there are three types of dehumanization to think about: how others view you, how you see yourself, and how you view others. The researchers say that these types can affect each other in different ways: through mutual dehumanization, indirect dehumanization, and making up for feeling dehumanized. In short, they argue that understanding these interactions is key to really understanding dehumanization.
