[catalogued under 4. Formal Logic / E. Nonclassical Logics / 1. Nonclassical Logics]

Full Idea

The exceptional status of an object with respect to some default is more likely to spread to other objects if they share properties with that object that may play a role in explaining the exceptional status.

Gist of Idea

We infer that other objects are like some exceptional object, if they share some of its properties

A Reaction

This is an example of the sort of rational behaviour we exhibit, and which a 'real life' logic would somehow need to capture. I would suggest the essentialist logic designed by Kit Fine as a first port of call.
