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.
