Similarly, quantification is separate from being rational. In your simple example "sum these assigned numbers and pick the highest option," how did you assign those numbers? In most real life scenarios, qualities are difficult to quantify. If you start from questionable quantifications, as the saying goes, "garbage in, garbage out." Often the rational thing to do is to acknowledge the nigh-impossibility of quantification (let alone combining those quantifications; what if the qualities interact in nonlinear ways?).
