Nine Methods for Testing a Worldview:
1. Coherence Test: Is a particular worldview logically consistent?
An acceptable worldview will avoid "self-stultification," but will have component parts that hang together as a coherent whole.
2. Mean Test: Is the worldview balanced between complexity and simplicity?
An acceptable worldview will be neither too simple (reductive fallacy) nor too complex (Ockham's Razor). All things being equal, the simplest, most economical, and yet fully orbed worldview is to be preferred.
3. Explanatory Power and Scope Test: How well does a worldview explain reality (power), and how complete is the evidence in support of the view (scope)?
An acceptable worldview will explain reality and offer a breadth of evidence in support of its conclusions.
4. Correspondence Test: Does a particular worldview correspond with well-established, empirical facts?
An acceptable worldview will match with the observed world.
5. Verification Test: Can the central truth claims of the worldview be verified or falsified?
An acceptable worldview will make claims that can be tested and proven true or false.
6. Pragmatic Test: Does the worldview promote practical and workable consequences?
An acceptable worldview will be practical, workable, sensible, and therefore "externally livable."
7. Existential Test: Does the worldview address the internal needs of humanity?
An acceptable worldview will account for the human need for meaning, purpose, and significance, and therefore be "internally livable."
8. Competition Test: Can a worldview successfully compete in the marketplace of ideas?
An acceptable worldview will be able to respond to reasonable challenges, and offer a critique of competing worldviews.
9. Predictive Test: Can a worldview successfully anticipate future discoveries?
An acceptable worldview can help humans make some accurate predictions of what their research into the macrocosm and microcosm will yield. It accommodates and incorporates emerging data.
