Meanwhile ideas have evolutionary pressure too. It's called memes. Memes work best when they require low effort from their carriers. If a meme requires some existing knowledge, & truth often relies on knowledge, that means it can only be transmitted to those with the knowledge, unless it brings that knowledge as baggage
Yes I think the same, it's certainly a comforting story to tell oneself about why people reduce the complex world to simple narratives, thus narrative fallacy if it exists falls prey to narrative fallacy.
However I have to assume that I could be wrong and what I perceive as examples of this narrative fallacy and demonstrating its existence do nothing of the sort.
Finally, the evidence all around us that I perceive does not lead to a proof of a biological inclination. It just leads to my consideration that there might be one.
So if Jeff Bezos or Nassim Taleb tells me it's a biological inclination, I would be inclined to find some polite way to tell him to prove it.
One of my personal pet peeves around this fallacy is how often it arises in sports. Before Jordan won 6 championships, he was a "great player who didn't elevate his teammates". After all the winning, he became "the greatest player to ever play". People just want a simple story, because they're busy - it's hard to have a nuanced view of everything you see or hear about.
