The score, by itself, is a piece of data/information. The score has never been, itself, the decision. A score is intended to be used in a context such as granting credit or the airline passenger context you mention. I think you are right on the nose here, incorporating a score into a decision system both helps eliminate using it incorectly and the potential for bias. Both the "rules" and the score work together to make the decision in a systematic way. I've seen instances of organizations implementing scoring who didn't understand how the decision strategy (aka rules) worked together and therefore received poor results or a significantly reduced benefit. James,

The next problem is that this human should use the predicted score as what it is, a hint only and not rely too much on it.
