Persuading A Jury - Evaluation (2)


Whilst the lack of ecological validity is the main evaluation point, other issues to consider include...

  • Sample = Usually students so lacks generalisability. As they may be gaining course credit, they may also show demand characteristics
  • Usefulness of research - It does help us to understand the ways in which juried can be persuaded (and therefore prevent it from happening) as only the actual trial evidence should influence a jury’s decision.
  • Ethical - This is the only way that research can be conducted into jury processes.

Research is almost always lab experimentation. Therefore, positive evaluation points of this method include.

  • Control -  Usually employs independent measures design, meaning trial materials (such as quality of evidence, length and complexity) can all be controlled for.
  • Replicability - Other researchers can replicate the work in other parts of the world, which adds to the reliability of the findings.
  • Cause and Effect - Can infer this if rigorous controls (such as those above) employed.
