I quite like that expression. It seems accurate to me, since, as it was pointed out by another commenter replying to you, people do not, in fact, check the experiments themselves, ensure that proper methodology was used, etc. They simply believe what the people in authority positions are telling them, so the word believe is quite accurate - you do not actually know the reasons why certain beliefs, theories are accepted by the scientific community, you just take their word for it.
Furthermore, any scientist does the same thing to the body research that was developed before him, otherwise, every scientist would have to start over.
I think people are more talking about believing in scientific institutions to ensure credibility and good faith research. Not necessarily that an individual institution is credible, but more the scientific community as a whole can be relied on.
Science is absolute, however the way we interpret and understand it isn't flawless and at the end of the day some level of belief has to be put into the fallible people behind it.
The scientific laws that govern how everything functions from subatomic particles, to beehive structure, to gravity are absolute and unchanging. Our understanding of them is flawed and changes over time, but the laws themselves can't be changed.
As far as I understand, science is a human endeavour, so I would certainly not say it is absolute, but I see what you mean.
Although I would say, my position is somewhat different, I do not see any reason to believe that even if these "laws" exist, science has at any level access to them, the "nature of reality", if you will, "laws of the universe" are metaphysical concepts that can only ever be speculative, scientific laws are not interpretations of them, they are separate constructions.
But you do have to believe though. If you are just a brain in a jar, then all your empirical evidences are just illusions. At the very least you have to have faith that that's not the case.
Not knowing the answer to something isn't a belief problem, it's an ignorance problem.
For millenia we were ignorant regarding the relationship between the sun and the earth. That didn't make cosmology a belief system. We were just wrong.
You are not getting what I was saying, let me put it this way, how do you know this isn't just all a dream you will one day wake up from, and find out that the real real world is run by wizards and dragons?
