Deindividuation / 去个体化

Deindividuation / 去个体化 is the source’s concept for what happens when a person stops experiencing themselves, or the target, as a concrete individual and instead acts inside anonymity, group identity, arousal, or responsibility diffusion. 123.人性实验：当心你自己！ connects [[GustaveLeBon|Le Bon]], Leon Festinger / 利昂·费斯廷格, Philip Zimbardo / 菲利普·津巴多, a masked shock experiment, and a Halloween candy experiment to online abuse and collective cruelty.

The episode treats deindividuation as a risk condition rather than a personality type. Darkness, masks, crowding, group language, anonymity, and perceived righteousness can reduce self-awareness and make another person’s pain less visible.

Key Claims

• Group membership and anonymity can change behavior without changing a person’s underlying moral vocabulary.
• Responsibility diffusion makes small violations easier and can escalate when the group normalizes them.
• Online environments can reproduce deindividuation through avatars, handles, swarm language, and fast collective judgment.
• The most dangerous form is when discomfort is suppressed by a feeling of justice.
