How do you tell when the news is biased? It depends on how you see yourself

… Many people have tried to define what media bias is, and attempted to measure it, but I want to try to answer a different question here: not how we can decide if the news is biased, but how each of us actually does decide — and what it means for journalists. … Communications researcher Scott Reid has proposed that we can explain the hostile media effect through the psychological theory of self-categorization. This is a theory about personal identity and group identity, and it says that we “self-stereotype,” placing conceptual labels on ourselves just as we might make assumptions about other people.
