Subjective judgments do not become objective simply by translating them into numbers. More importantly, when some of the options under review require ethical considerations, we can cloud the difference between right and wrong when we translate all options into a quantitative order of dollar values. If you tell me that option A contains a moral impediment and option B is pristine, that is substantially different than if you tell me that option A has a probability adjusted present value of $2 compared to $1.50 for option B. And yet we tout the virtue of net present value analysis because it does that very thing.
