Well, arguably science is just the superior faith-based system. Nothing is ever proven, but it contains a method to constantly find the theory most likely to deserve your faith.
The "real" science has no absolutes. But the problem is that it is very difficult for humans to operationalize it that way. Take for example eggs and cholesterol. I remember in the late 80s, my father (also a scientist/biologist) stopped eating eggs because apparently Science said eggs are bad for you (due to some papers)... later in the mid/late 90s Science said that eggs are actually not bad, but good for you (because, even if they where high on cholesterol, it was the good cholesterol).
So, for people (even other scientists!) that are not experts in the subject, it becomes a matter of belief... believe in the papers some random team published, because it was published in Nature.
