We seem to like “protecting” ought by making false claims about what is.
This has interesting implications for consequentialism vs. deontology. Consequentialists, at least around here, like to accuse deontologists of jumping through eleborate hoops with their rules to get the consequences they want. However, it is just as common (probably more so) for consequentialists to jump through hoops with their utility function (and even their predictions) to be able to obey the deontological rules they secretly want.

Real humans are neither consequentialists nor deontologists, so pretending to be one of these results in arguments like that.
