Such a system is already in place and has been tried using the religion moderator’s guidelines, with scientism being classified as a religion and, hence, given religious protection on this forum. If you don’t think scientism is a religion, then why do you use the term “believe in Science”?
“Believe in Science” is a phrase. At the end of the day, the reason it is NOT a religion is that it has no fixed precepts. It “evolves” (to use a phrase) based on our knowledge.
Back in the 19th century, Newtonian physics “ruled”. Now “Einsteinien” physics dominates. Who knows where we go from here.
Science is a journey of discovery. It is constantly disproving itself.
Religion is more set. For example, I believe in God. I don’t think any evidence is going to make me rethink that belief.
However, in God’s universe, I believe we have the capacity to learn new things.
I believe in religion in the sense I believe it exists and has many interesting stories. I believe in science in that it exists and has many interesting theories. I believe the theories when the preponderance of the evidence indicates they are most likely true. Perhaps rather than say I believe in science, we who do should say “I believe scientific evidence” when there is enough of it and it is reproducible. Unfortunately religion has little reproducible evidence, which is why it is not science.
