How do narratives relate to heuristics?

Narratives and heuristics are both tools for dealing with uncertainty, intractability, and incommensurability, that is, for all real-world situations outside the domain of Bayesian decision theory. But how do narratives and heuristics relate? I suggest two links: Heuristics select narratives to explain events, and big narratives select the heuristics that people live by, to execute their values and moral principles.

Narratives and heuristics are tools for handling complex real-world situations. Heuristics choose narratives to explain events, while big narratives influence the heuristics that individuals adopt to live according to their values and moral principles.
