A strength of the cognitive interview (CI) is the strength of the research supporting the technique's effectiveness. When the CI was used instead of the standard police interview (SPI), there was a 41% increase in accurate recall from a witness, demonstrating its effectiveness in improving eyewitness recall.
However, we must consider how it was found that there was an increase in inaccurate information recalled when the ECI was used, but this does not mean we should abandon the CI and the ECI. Despite the technique's limitations, the 41% increase in accuracy of the CI can have a positive impact, such as reducing false imprisonments and improving the justice system as a whole. Therefore, instead of criticising the CI and the ECI, we should consider them from a positive perspective and look at how they can be improved instead.
Furthermore, the CI has been found to have real-world applications as well. This is a strength because although all 4 techniques have been found to be accurate in improving recall, reporting everything and context reinstatement have been found to be the most effective when used in combination. Therefore, using these 2 techniques in particular could lead to more of the correct offenders being put away, allowing for society to be protected and justice to be served to victims. This demonstrates the credibility of the CI.
What should be acknowledged, though, is that it could be argued that not all elements of the CI are useful if two elements being used in combination are producing the most accurate recall. This demonstrates how conducting the full CI is a waste of time and resources, as police require specialist training to conduct the CI, which is extremely time-consuming and costly. This therefore decreases the effectiveness of the CI as it can sometimes not be a realistic method for police to use to interview witnesses.
"Decreasing the effectiveness of the CI as it’s not a realistic method for police to use to interview witnesses with" is an assertion that needs evidence to back it up.
"The 41% increase in accuracy of the CI can have a positive impact such as reducing false imprisonments" is an assertion considering you stated it also increases the likelihood of inaccurate information.
