    Precedence: bulk

    Moving on to your precept #3:

    >>3. If two theories exist, one is chosen and the other rejected on
    >>extra-scientific criteria such as consilience, beauty, symmetry, Ockham's
    >>Razor or some combination of these. Note that this list is probably

    Scientific theories are evaluated by many diverse criteria. The particular
    list of applicable criteria are chosen on a case by case basis. Here's an
    excerpt from something I recently worked on:

    > 1. Observational relevance. Is the theory vulnerable to affirmation or

    > 3. Coherence. Is the theory under scrutiny internally consistent? Is it also
    > consistent with other theories considered to be well supported?

    > 4. Explanatory scope. Does the theory apply to a broad range of phenomena,
    > or is it confined to a very narrow class of phenomena?

    > 5. Unifying power. Does the theory under scrutiny serve to unify several

    > 6. Fertility. Does a theory suggest and stimulate further experiments or
    > measurements?

    > 7. Aesthetic qualities. Does the theory display aesthetic qualities such as
    > simplicity, elegance, beauty, and the like?

    Another aesthetic quality that is often very influential but difficult to
    deal with is "Worldview comportance: How well does the theory under
    evaluation comport with the fundamental tenets of one's religiously relevant

    Here's another area where ID science will operate differently from normal
    science. I suggest that it is the prominent role of Worldview Comportance
    that leads ID advocates both to reject theories constrained by MN and to
    place high value on theories that explicitly include the possibility of
    non-natural form-conferring action performed by an unidentified, unembodied,
    choice-making agent. I presume that ID advocates, on the other hand, would
    argue that proponents of all forms of naturalism (methodological, minimal,
    maximal, et al) are allowing the value of Worldview Comportance
    (specifically, comportance with naturalism) to dominate the natural sciences
    and to maintain a bias against ID science.
