2. Deindividuation Theory
Based on Le Bon (1895) Individuals are transformed when in a crowd.
An individual in a crowd ‘descends several rungs of the ladder of civilisation’.
Anonymity + suggestibility + contagion
= ‘collective mind’ possesses individuals.
The individual loses self control and acts against personal/social norms.

22. What is the connection?

23. Gustav Le Bon (1885)
Crowd theory: He recognised that when in an anonymous crowd a ‘group mentality’ can take over a person and they can easily lose their self-control, carried away by the contagious nature of the group. He also suggested this was an animal like mind – like a pack!

24. Deindividuation Theory
Zimbardo (1969) introduced the theory of deindividuation to explain why membership of a large anonymous group can lead to more antisocial behaviour than if individuals are on their own.
According to deindividuation theory when someone is part of an anonymous group (particularly if wearing a uniform) they lose their personal identity and their inhibitions about the way they behave, some people may even become violent.

25. The process…
Being anonymous, your inner constraints (inhibitions) are reduced and your fear of consequences are reduced.
People lose sense of personal values and normal social norms. It is usually seen as a negative thing!
