Slander
Calling Social Costs Witch-Hunting is slander. Information encourages pro-social behavior.
No one is willingly just, but only when compelled to be so. (Plato, The republic 360c-d) “Identifiable Victim” effect (Schelling 1968).

To the extent that 50–50 splits are deemed to be a social norm or a fair outcome, even selfish humans are more likely to act fairly when in public.” (p.141)
