Your model needs a definition of what is a "«finding»", destined to become an «accepted fact», and a "«have[-]been» idea", for which «scientific evidence [will] show[] that we were completely wrong». Because they are not easily distinguishable.

Edit: I do not know what meaning you intend to be giving to 'scientism', but partisan cheering is not sport, nor science, nor religion.
