I have done data modeling for a living and I don't agree that you don't learn anything and that it's used to justify something - you just have to do it rigorously. To that point though, most modeling with any accuracy is done by computer now, and not by hand, which is what my point is. It's impossible to gain an intuition about something if the computer just tells you the answer.
