Ah that broken model which assumes that moral reasoning has a relation to moral action, which it clearly doesn't for the majority of the population of this rock...

[acuozzo]

Citing the broken assumption upon which the model is (partly) based isn't enough to claim the model has no value, as you're clearly implying.

An example: A model of the universe is useful, even if it was developed under the assumption that it was created by supernatural forces.

Please don't use such weak argument tactics in the future, as they're just childish.
