Very interesting take on what is a paradigm. I'd say this (new to me) perspective would itself be a paradigm shift but I would be using the term incorrectly.

The word 'usefu'l is crucial to understanding the strength of 'paradigms', theories, models etc. (i.e. not whether in any absolute sense, as opposed to relative appeals to such terms, they are 'true', isomorphic etc.)

An interesting aside of sorts is that they define science here as those aspects of the physical world that act in large numbers over very small segments of time and space. The social sciences are "not science" because the statistics of social science is too narrow, too small a sample, and that the actions that are studied are too large in time and space to be able to derive a "true science".
