Deindividuation

• Supporting evidence

  Douglas and McGarty (2001)- They found that the most aggressive messages were sent by those hiding their identity.
• Practical application

  If aggressive behaviour is more likely to occur in darkness, in conditions of anonymity or in crowds:

  •Areas should be well lit

  •CCTV should be used

  •Police should monitor large groups of people
• Contradictory evidence

  Johnson and Downing (1979)- They found that those dressed as nurses were also more compassionate to their ‘victim’.
• Other explanation

  Neural and hormonal mechanisms and genetics.
• Issues and debates

  Deterministic
