>Imagine a person meeting friends in a bar, or at a dinner party. They're likely to exchange stories they read about in the news. "So this politician said $outrageous-thing!" (taken outside of context, but who cares), says the person. "Oh yeah, all X are bad, have you heard of $event-that-never-actually-happened?", replies the person B. The conversation goes on. Ultimately, little to no truth was exchanged, but people bonded together. Fiction served its social function.

If I hear something that seems right and I start repeating it, I generally try to go check if I am talking rubbish or not. If I find out that I am, I stop repeating the thing, or I include the truth next to the story, if the story is entertaining enough in and of itself. I tried to explain why I do this, while having a recent discussion with a visitor about the Navy vs Lighthouse story - https://en.wikipedia.org/wiki/Lighthouse_and_naval_vessel_ur... and was told that what I was doing was anti-social and that I wasn't helping anyone by being interested in the truth of things that people have said. I tried to explain that I was doing it to satisfy my own curiosity for the main part, and this completely floored them. They could not understand the motivation of being personally interested in the reality of a story, for them the only value was if they liked the story.
