I think there is a certain “cost amnesia” that sets in after a “good” decision? Even for fairly large costs. So the “indistinguishability blindness” is often a cognitive response to maintain the image of a good decision rather than determined by hard numbers.
Regardless, this is likely entering speculation territory. It’s something I’d noticed in my own life as well as in policy decisions i.e. a negative reaction to talking about fairly large costs because net-benefits were still positive.
