Television is a form of one-way entertainment, but that's not how people want to think about it. They want to believe they're somehow involved.
This is why they talk back to the TV. This is why they get upset if certain characters don't behave in a likable fashion.
This is why they complain when the story moves further from their own personal definition of interesting.
This is why they criticize boring episodes on the Internet and expect the show's writers to study their thoughts and care what they think.
This is why they love shows that involve voting. They believe their personal experience with television effects what television is.
But television is the only place where this belief exists. Within their actual life, they feel powerless. They believe voting is frivolous. They think caring is a risk. They assume they have no control over anything, so they don't even try.
They perceive reality backward.
