The heckler's veto is also subject to the unilateralist's curse

Abstract

Unilateralists may take individual actions that deviate from the group’s common interest due to positive error terms in their assessments. This problem extends to situations where a single individual can act or veto an initiative on behalf of a group, making the group vulnerable to unilateralist errors. Karma systems, such as those used on online platforms, may mitigate this risk by penalizing harmful posts and offering feedback about their perceived value. However, the effectiveness of karma systems in preventing unilateralist actions depends on the assumption that users reliably downvote infohazardous content. – AI-generated abstract.
