People are interested in forensic psychology because of crime dramas, but the reality is that what is depicted in crime dramas is not as simple in real life. Psychological understanding and assessments aids in avoiding wrongful convictions and obtaining evidence from eyewitnesses.
As we all know, eyewitnesses play a significant role in investigations. Because eyewitnesses are human and prone to making mistakes, the precision and effectiveness of the evidence they can provide is limited. As a result, in order to improve investigations, we must first understand how the mind works.
According to research, if you show a witness a line-up of pictures and ask them to identify the offender, they are more likely to pick someone even if they are unsure or the offender's picture is not listed. Changing the way questions are asked can have a significant impact on the answers and help reduce the number of cases of mistaken identity.
It is information like that included in your posts, @Erna Ngoma and @Elvi , that show why forensic psychology and educating the public is so important. Most jurors are completely unaware of the research and concepts you are describing. This can lead to some jurors being misled or overly confident in things which may lack a strong foundation or may be riddled with errors and biases.
