I'm not sure what the name of this fallacy is, but I fall prey to it all the time: the fallacy that everyone else values what you value.

I can't stand fiction. When I read a self-help book, but it's laced with stories, I lose interest. Just state the point.

However, a lot of people find stories engaging and more effective, because they provide an example that they can use to relate to, like a myth.

I don't think this is worthless at all. It wraps information in an engaging presentation.
