Classroom-level moral disengagement exceeds the sum of individual member disengagement.

Evidence

In collective moral disengagement, classmates influence one another such that their group moral disengagement is usually greater than the sum of their individual mind-sets. Hence, the level of classroom moral disengagement accounts for the amount of bullying in schools over and above the predictiveness of individual moral disengagement (Gini, Pozzoli, & Bussey, 2013). — Albert Bandura, Moral Disengagement, 280

Categorization

• DEEPTHINKING: The claim that collective moral disengagement exceeds the sum of individual mind-sets is a genuinely emergent social phenomenon - contagion where the group becomes more morally unbound than any member alone - worth sitting with.
• XREF: Connects to Zimbardo’s deindividuation findings and to group polarization research in social psychology.
