Persuading A Jury - Evaluation (1)

Ecological Validity:

  • Due to mock trials needing to be used – a lack of ecological validity is the main criticism of research in this area.
  • E.g. Pennington and Hastie used a lab experiment – not a control group
  • Real-life trials go on for weeks; mock trials are only a short process
  • No emotion involved – as no ‘live’ witnesses are presented
  • The livelihood of the defendant will not be hanging in the balance of the jury’s decision.

Several differences exists between real trials and mock trials:

  • The livelihood of the defendant will not be hanging in the balance of the jury’s decision
  • Real trials can go on for weeks. A mock trial will be a very short process in comparison
  • Mock jurors will often simply have to read evidence, rather than it being presented by ‘live’ witnesses – less emotion
