And this is why there is so little truth to be found in the humanities.
Here's a scenario: A white nationalist kills dozens of Muslims. Someone looks at this and sees evidence that the normalization of fringe views, characteristic of the way president Trump talks, is emboldening these maniacs to act violently. Someone else looks at this and sees evidence that white middle-class uneducated men have been marginalized by our economic system and are at their wits' end, which is the same phenomenon that lead to Trump being elected.
The kind of narrative-based elaborate analyses that you advocate doesn't help us decide which of the points of view above is right, and we carry on with our preconceptions, unable to learn anything.
Narratives allow you to explain the past perfectly using models that have no predictive value. The only way to make progress when trying to understand a complex system is to come up with very simple hypotheses and try to validate them empirically. Of course this is very hard to do, but I think people in the humanities do a poor job and fool themselves into thinking they understand things they don't understand.
