You're still investing some degree of faith in the theory though aren't you? You're also putting faith into other scientists, and the empricism itself. Admitedly, it's a more calculated investment as you are relying on 'evidence' as opposed to conjecture to form your perspective and positioning; I'd much rather read a scientific paper than seek council from a witch-doctor.
Even the likes of the theory of mavity for instance, require us to place faith in it. Einstein overthrew Newton's understanding of mavity with the introduction of special relativity despite Newton's equations being used accurately for years before-hand. We are placing belief in that our theories -- based on evidence -- are correct as opposed to alternatives. Don't be foolish to think that science has all the answers as it simply hasn't; it can only attempt to describe and predict in the simpliest way. Indeed, theories can be proven to work through accurate predictions yet can still be overthrown. We're placing belief in the assumption that we have enough of the picture to think that what we see around is actually the case when in reality we don't know what's around the corner.
I think you need to do a little brushing up on your understanding personally.
