*In fact, the logical disconnect between effect and cause is probably a strength rather than a weakness.

Absolutely. I remember reading about an artificial life program which had evolving creatures try to survive in a very harsh artificial world. The strategies developed seemed less than optimal on the face of it, but when the writers of the program hand-coded their own supposedly "perfect" strategy, the increased efficiency of their strategy actually led to a lower overall survival rate. Only after that could they see why.
