Tyler Cowen argues in a TED talk (~15 min) that stories pervade our mental lives. He thinks they are a major source of cognitive biases and, on the margin, we should be more suspicious of them - especially simple stories. Here's an interesting quote about the meta-level:
What story do you take away from Tyler Cowen? ...Another possibility is you might tell a story of rebirth. You might say, "I used to think too much in terms of stories, but then I heard Tyler Cowen, and now I think less in terms of stories". ...You could also tell a story of deep tragedy. "This guy Tyler Cowen came and he told us not to think in terms of stories, but all he could do was tell us stories about how other people think too much in terms of stories."
That's not a good heuristic. There are a lot of people - Eliezer would name Robert Aumann, I think - who are incredibly bright, highly knowledgeable, and capable of conveying that knowledge who are wrong about the answers to what some of us would consider easy questions.
Now, I know Berserk Buttons (warning: TV Tropes) as well as anyone, and I've dismissed some works of fiction which others have considered quite good (e.g. Alfred Bester's The Demolished Man, TV sitcom The Modern Family) because they pushed those buttons, but when it comes to factual information, even stupid people can teach you.
(Granted, you may be right about the worthlessness of this particular speech to you - I haven't watched it. But the heuristic is poor.)
The heuristic isn't widely applicable, but I disagree about it being poor altogether. As I pointed out above, it's not just that he defended good vs. evil. It's that he did it in the context of a presentation on a subtopic of how we conceptualize the world. He may have things to teach me in other areas, obviously.
That's why I compared it to someone bringing God into a discussion on ethics specifically. (Or, say, evolution.) That person may be brilliant at physics, but on the topic at hand, not so much.
It also occurs to me that this heuristic may be unusual... (read more)
