I think we should also separate the subjects of the psychology behind when this might happen and whether or not we are using scales.
It may indeed be the case that people are bad accountants (although I rarely find myself assuming these implied things, and further if I find that my assumptions are wrong I adjust accordingly), but this doesn’t change the fact that we are adding +/- points (much like you’re keeping score/weighing the two alternatives).
Assuming a perfectly rational mind was approaching the proposition of reactor A vs reactor B (and we can even do reactor C...), then the way it would decide which proposition is best is by tallying the pros/cons to each proposition. Of course, in reality we are not perfectly rational and moreover different people assign different point-values to different categories. But it is still a scale.
