Even if we assume for the sake of argument that all these inferences are subsequently tested by experiment, we can still ask how many laypeople are in a position to know what predictive successes are. They don't have access to the data-sets and wouldn't be able to interpret them if they did.
In real life, what laypeople are exposed to are the conclusions that scientists (or politicians or the media) tell them that they need to accept on Science's authority.
Everyone of us needs to accept at one time or another, a result or argument on authority, in many different disciplines,
I see nothing wrong with that, and in essence this is the type of argument that many alternative hypothesis pushers, or anti relativists use to give an air of respectibility to their own views on that discipline, when like you and I, they too do not have access to the myriads of data that they are questioning.
Yep, certainly I have faith and trust in science but certainly not without question, and just as certainly based on my own observations of seeing how science does advance humanity continually in many different ways.
I find that faith in mainstream science generally, as far more applicable and far more deserving, and far more logical, than having faith in some of the claims made by our ego inflated friends on this forum in claiming they have a ToE for example, and then in the next breath when questioned about the claim, start to cry conspiracy about the mainstream sector, and the unreliability in their opinion of the scientific method and peer review.
What I'm saying is that from the point of view of the street, there's little difference in being told to believe something based on the authority of Science and being told to believe something based on the authority of the Church. Medieval villagers were rarely in any position to understand the arcane disputations of the theologians either.
Plenty of difference in actual fact. My faith in science is not a blind, unwavering, unevidenced based faith on some mythical scenario, as a religious faith is.
My trust in scientific authority is based on reputation and reliability, and the acceptance of the scientific method and peer review.
Even scientists themselves need to take on trust and faith certain aspects of their work.
That is totally different then the blind, unwavering faith that is the hallmark of religion.
You may feel that your faith is justified by medicine's past successes, but it's faith in authority nevertheless.
Like I said, I see nothing wrong in a "faith in authority" that has been accepted by mainstream science, and is relevant to the scientific discipline in question.
Let me quote a giant of the past.....
"Anybody who has been seriously engaged in scientific work of any kind realizes that over the entrance to the gates of the temple of science are written the words: 'Ye must have faith.'
