Depricate - from Wiki:

In mainstream English, the infinitive "to deprecate" means, simply, "to strongly disapprove of (something)". It derives from the Latin verb deprecare, meaning "to ward off (a disaster) by prayer"

It is economic models with the sophistication of a wolf pack that we need to deprecate. But this usage is invidious to wolf packs, which actually exhibit long term survival capability in the environment in which they evolved and we cannot say that about 'mainstream economics.
