***The difference is that empirical models work, they work repeatedly and predictably, on demand. Subjective models don’t; they work “on hope,” and “mystery.”***
But empirical models only work for things that are included in the model. And empirical models are normally short term projects that usually don’t include all variables at the time of formation.
I agree on all points. The empirical model makes no pretense, nor does it demand acceptance beyond human comprehension. But it works on demands, predictably and repeatedly. They are dependable to the degree to which they produce the same results on demand, predictably.
The subjective model has none of these qualities. It is model of man's fancy (imagination); it cannot produce visible or otherwise tangible results; it's highly unreliable and unpredictable, but it claims omnipotence and eternal viability.
