Citation still needed

This is not Wikipedia. If you really believe that average people would not behave this way, say so. If not, asking for a citation is just filibustering.

You really think it's appropriate to object to somebody calling out your unsupported claims as unsupported when they are A) obviously disagreeing with you, to the point where there's absolutely no need to explicitly state it, and B) providing evidence in support of their own claims, with both reasonable arguments and supporting links? In that case, what would it take to convince you?

we have different opinions on organ selling based on irreconcilable differences in opinion about how human beings behave

(Emphasis mine) Should I take it that this is then something you can't actually be convinced of by anything short of incontrovertible proof to the contrary?

Most arguments are meant to convince bystanders. I don't believe that bystanders will think that assertion has a significant chance of being false

Data set of one, but I find Lumifer's arguments far more convincing than yours. This is largely based on the fact that they are actually backed up by something more than the assumption that everybody begins with your personal model of how people make decisions.
