Open Question: Why is false praise seen as so much less harmful than false criticism?
“Presumably the reason we now allow suits for false defamation is that we see a net social harm there; others are liable to be misled, causing misallocations of resources and relations. In addition, resources may be wasted in back-and-forth defamation battles. But it seems to me that we should also expect similar social harms to result from false positive comments, not just false negative comments. So maybe we should consider having law discourage those as well.”-Robin Hanson, “Why Not Also Punish False Praise?” OvercomingBias.com. October 31, 2019.
