A "model" of reality can be something as simple as a subconscious method for estimating where a ball will land when thrown with some amount of force - something which you don't really think much about before doing.
It can also be something so complex as the theories manipulated by particle physicists.
Like those theories of particle physicists that took so long to devise, a subconscious understanding of where some object is likely to land when thrown can be quite useful. Yes, reality changes, but from my observations, it does not change quickly enough to make investment in more complicated and computationally expensive models necessarily wasteful.
I seek to create a formal framework so that I may say "X is bad." and do so with proper philosophical backing.
Perhaps my statement that "X is bad." will be based on an estimation, but at least this estimation will be based on something reasonable, and will be subject to disproof when/if presented with good counter-evidence.
