For example [vaguely]: writer creates a character who behaves like X, despite nobody actually behaving like X in real life. Then characters behaving like X become a wide-ranging trope. People in the real world begin to think it’s normal to behave like X, and subsequently start actually behaving like X themselves.
Any actual examples of this phenomenon happening?
‘Drama’ seekers and what I might call drama-pigs. There are a lot of people who think relationships are ‘supposed’ to have drama. They see versions of relationships, romantic or friendships, in dramas and romances written to be interesting from the outside and absorb it as normal. The result is deleterious. The other side of this is the drama-pigs, people who feed off of the real-life dramatics of people’s lives as entertainment. They read AITA posts or watch drama vlogs as though the people involved were characters in a story rather than real people who are dealing with real problems.
