This is a common misconception. Credit scores are actuarial risk, not profit utility. Having some debt load is a portion of that equation because it basically prevents dividing by zero. This is very basic actuarial science - you cannot produce a risk/utility metric without actually having priors, and within those priors there's a concept of Fisher Information, which measures the likelihood that some sample of a random variable reflects true information about an unknown parameter. Simply put, the more information you have, the stronger the model. So the more debt you manage the more information about your debt management practices is available to the actuary. Up until the point that you have too much debt that it becomes very certain that you are high risk. If you have little credit history, but that history is perfect, you will still usually be in the lowest risk tier, but that might be like 780 instead of 850, or whatever, and that's merely a reflection of certainly within the model, not your actual behavior. A person with similarly perfect behavior, and a lot more of it, should be intuitively seen as a lower risk.
