Kuhn’s criteria for theory-choice:
Accurate – empirically adequate with experimentation and observation.
Consistent – internally consistent, but also externally consistent with other theories.
Broad Scope – a theory’s consequences should extend beyond that which it was initially designed to explain.
Simple – the simplest explanation, principally similar to Occam’s Razor.
Fruitful – a theory should disclose new phenomena or new relationships among phenomena.
But as Mitch Hedberg said, “There’s more to it than that!” Here are some additions, and I believe there are even more:
Meaningful – the theory’s compatibility with the theorist’s grounding orientation to life.
Contiguous – the theory’s capacity to integrate with an existing body of theory.
Intelligible – the theory situates the theorist in a world whose relevant features are intelligible.
Congenial – a theory should employ the theorist’s cognitive natural/acquired intellectual strengths.
Social – a theory’s reinforcing affirmation by a community with whom the theorist identifies, or, antithetically, it’s reinforcing rejection by a community against whom the theorist has defined himself.
Applicable – the existence of opportunities to use the theory practically and to develop the tacit intellectual practices (know-how) inherent in all practical application of theory
Concrete – the number of concrete examples available to 1) explicit demonstrate how the theory is practically applied and 2) to demonstrate its applicability
Spontaneous – a theory’s ability to shed conscious interpretation and to disappear into the phenomena themselves.
