I think we utilize some level of faith in our fellow man, but that's more of an option than a necessity. Ultimately, when we lack faith in the science produced before us, we are encouraged to test it, to research how these beliefs were formed and re-perform the tests these beliefs are based upon.
This is how I believe it differs from the type of "blind" faith required by many religions, because ultimately the proof of the faith working apparently requires faith beforehand as an ingredient to work, therefore it's the perfect escape clause when proof is not acquired: the person lacked faith therefore they were not supplied with proof to reinforce their faith!
Science doesn't work this way. You don't need faith in an outcome to test it, you merely must perform a test. This is why it is neutral and reliable.
