supporting evidence

A
  • fischer

  • and 63% more info that control of untrained detectives
  • suggesting CI is effective at improving EWT

Q

high validity of supporting evidence

A
  • fischer used real life detectives
  • meaning the study has high ecological validity and findings can likely be generalised to other police and their EWT techniques
  • study therefore has high external validity and provides strong supporting evidence for CI improving accuracy of EWT

Q

CI is time consuming

A
  • CI is time consuming and requires time, money and resources that most police departments dont have readily available to them
  • especially as police are involved in multiple cases at once some of which are time sensitive
  • so CI may not be a viable option in all departments
  • limited method of improving EWT

Q

cost benefit (+)

A
  • CI has positive economic implications
  • cost benefit analysis considers the over effect of CI on the justice system even regarding that its time consuming and expensive
  • improving EWT improves efficiency of convictions and therefore reduces crime and therefore strain on the police force and the economy
  • so it may be worth while taking time to train officers
