From Reknew:

The second pointer arises from our common experience related to what we assume to be true in our daily life. The contemporary quantum physical paradigm of reality is reinforced by our common experience. Indeed, I would argue that the complementarity of determinacy and indeterminacy is a metaphysical principle, and thus is universally instantiated. Every event seems to exemplify it. From quantum particles to molecular structures and from the behavior of single-celled organisms to the spontaneous movements of insects, birds and mammals, including human beings, we find a dimension of individual indeterminacy within a broader parameter of determinacy. Sociology has taught us, for example, that group behavior is remarkably predictable, though the behavior of any individual within a group is not. So it is with most animal behavior.
