• strength- entire CI not needed

  • Milne and Bull (2002) suggested, where context reinstatement and report everything produced the greatest accuracy of recall of correct information as compared to any other combinations of steps.
  • even if police force dont have enough time to train for whole thing, gradual changes from standard police interview can increase accuracy and reliability of EWT
• limitation- increase recall of inaccurate info

  • The CI does not only increase the recall of correct information by 81%, but also increases the recall of incorrect information by 61%, as suggested by Kohnken et al 
  • This appears counterintuitive when considering that the chief aim of the CI was to improve the accuracy of recall of correct information and so decreases validity of eyewitness testimonies overall- false convictions, highly unethical or no convictions
• limitation- little practical value

  • due to being too time-consuming and requiring specialist skills. For example, researchers argued that only a few hours of training, as is possible for many police forces, is insufficient to adequately train interviewers, especially for the enhanced social understanding required for the enhanced cognitive interview. 
  • Therefore, this lack of time for training may explain why some forces may be unimpressed with the CI.
