Eyewitness Testimony Research Paper

Eyewitness evidence has always been considering critical information when it comes to court trials and convictions. But how reliable are eyewitnesses? Scientific research has shown that eyewitness’s memories are often not accurate or reliable. Human memory is very malleable and is easily changed by suggestion. Relying on eyewitness evidence instead of scientific data often leads to wrongful convictions. Scientific evidence is much more reliable, and should be more important in court cases than eyewitness evidence.

According to “The Science Behind Eyewitness Identification Reform” there are two main variables that affect eyewitness testimonies “Estimator variables: are those that cannot be controlled by the criminal justice system. They include simple factors like the lighting when the crime took place or the distance from which the witness saw the perpetrator, and the degree of stress or trauma a witness experienced while seeing the perpetrator” and “System variables: are those that the criminal justice system can and should control. They include all of the ways that law enforcement agencies retrieve and record witness memory, such as lineups, photo arrays, and other identification procedures”. Eyewitness misidentification has led to 75% of false convictions that were overruled by modern DNA testing according to “The Innocence

Eyewitness testimony has long been viewed as important evidence in court cases. The general population believes eyewitness identification more than any other evidence, even if the witness account is conflicting with the other evidence presented. Studies show that eyewitness testimony is unreliable, and yet it is still considered the most important form of evidence. People think that if a person says they saw something then it must have happened. Currently there are no universal guidelines on how to obtain and present such evidence. The purpose of this paper is to explain why eyewitness testimony is unreliable, and discuss the proposed guidelines on how law enforcement agencies should gather identifications, as well how

The reliability if an eyewitness testimony is questionable. The witness may be so certain that the person that thy are pointing out is one hundred per cent the suspect or they could be so certain when it comes to retelling the incident, although these people are so sure on what it is they are doing, their testimony cannot always accurate. Due to the lack of accuracy with eyewitness

Also they could lie for the perpetrator so then when they get out of jail or prison they don’t come after the witness, like in a domestic abuse case, or a rape case. Many people believe that the human memory works like a video recorder like the mind records events and then, on cue, plays back an exact replica of them. Psychologists have found that the memories are reconstructed rather then played back each time we recall them. On this website (https://www.scientificamerican.com/article/do-the-eyes-have-it/ paragraph 4) they state that “The act of remembering, says eminent memory researcher and psychologist Elizabeth F. Loftus of the University of California, Irvine, is ‘more akin to putting puzzle pieces together than retrieving a video recording.’ Even questioning by a lawyer can alter the witness’s testimony because fragments of the memory may unknowingly be combined with information provided by the questioner, leading to inaccurate recall.” The more violent the event, the least likely it is that the witness or victim will remember the event with accuracy.

There has been considerable interest and study in the accuracy or inaccuracy of the use of eyewitness testimonies in the current criminal justice system. Results collated by several studies add to the bulk of literature suggesting that the current usage of eyewitness testimony by the legal system is far from ideal. Currently, high emphasis is being placed on reviewing and reconsidering eyewitness accounts (Leinfelt, 2004). In particular, recent DNA exoneration cases have substantiated the warnings of eyewitness identification researchers by showing that mistaken eyewitness identification was the largest single factor contributing to the conviction of innocent people (Wells & Olson, 2003). In this essay, the use of eyewitness testimony in the criminal justice system will be explored, with a particular focus on the impreciseness of this practice.

Eyewitness misidentification can pose a serious threat in forensic evidence. Eye witness testimony can easily be tampered with due to words or phrases used. Bias is a major issue in identification especially if the police officer uses suggestive tones to portray whom they believe is the suspect. Some witnesses will change their opinion when they hear new information of the suspect. A study has shown that words can play a major impact in the witness' mind and cause them to recall false information. False information can also stem from human memory, age, distance, and how long it took before a witness could recall the information. It has been shown that due to the confidence that a witness may have, it could impact the court systems' reliability on the witness; however, there are several solutions that can be done to prevent misidentification in the court of law. Some examples that can be done are blind administration, lineup composition, instructions, confidence statements, and

Research shows that the human mind is not like a tape recorder, we neither record events exactly as we see them, nor recall them like a tape that has been rewound. Instead, witness memory is like any other evidence at a crime scene; it must be preserved carefully, or it can be contaminated. A case I would like to mention is the Calvin Willis Case. One night in 1982, three young girls were sleeping alone in a Shreveport, Louisiana home when a man in cowboy boots came into the house and raped the oldest girl, who was Ten years old. When police started to investigate the rape, the three girls all remembered the attack differently. One police report said the Ten year old victim didn’t see her attacker’s face. Another report which wasn’t introduced at trial said she identified Calvin Willis, who lived in the neighbourhood. The girl’s mother testified at trial that neighbours had mentioned Willis’s name when discussing who might have committed the crime. The victim testified that she was shown photos and told to pick the man without a full beard. She testified that she didn’t pick anyone, police said she picked Willis. Willis was convicted by a jury and sentenced to life in prison. In 2003, DNA testing proved Willis’ innocence and he was released. He had served nearly Twenty Two years in prison for a crime he didn’t

As time goes on, eyewitness testimony has become more and more of a disputed topic due to many different factors. The first study I was exposed to was in an introductory psychology class which sparked my interest into the topic. For this reason, I chose to look at different demographics such as, gender and major, and see if those factors had any impact on the perception of eyewitness testimony. My main issues remained the same throughout this research project.

Eyewitnesses are critical to the criminal justice system, but there have been issues involving eyewitness testimonies, which occasionally cause them to be seen as unreliable. According to innocenceproject.org, 72% of DNA exoneration cases in the United States have resulted from eyewitness misidentification. This is concerning because in a study by Benton, Ross, Bradshaw, Thomas, and Bradshaw (2005), they examined jurors, judges and law enforcement’s knowledge about eyewitness issues. They found that those involved in the legal system are still very unaware of eyewitness memory research, and the reasons behind why eyewitnesses may or may not be considered reliable. There needs to be a way to increase reliability so that eyewitnesses are able to accurately recognize perpetrators and other important information to put the guilty people away, and to keep the innocent people free.

First, the human memory does not record all information like a video recorder. Mistaken eyewitness testimony is one of the major causes of wrong conviction. Events of crimes, will have so much stress or focus on a weapon, than the face of criminal (Wrongful Convictions , n.d.). The victim’s or eyewitness’s memory can be changed with an easy simple suggestion. Police procedure dealing with key witnesses by a “show up”. This is showing the suspect in a physical or a picture line up. The confidence of accuracy of identification and exhibited by the witness is a “crucial determinant of believability” by jurors (Furman, 2003). The best result of eyewitness testimony is taken identification immediately. The

The impact of eyewitness testimony upon the members of a jury has been the subject of various research projects and has guided the policies formed by the federal government regarding its competent use in criminal matters (Wells, Malpass, Lindsay, Fisher, Turtle, & Fulero, 2000). Therefore, eyewitness studies are important to understand how

There are many different ways our memory might fail us. Encoding failure occurs when our brain fails to realize all the information around us and can only store what we are most focused on at the time. This causes people to lose information that could have beneficial because they didn’t focus on one single thing. This problem only gets worse with age. Storage decay can also affect the reliability of our memories. Even if the information does get encoded into memory, there is still a chance it could be forgotten over time. There is a forgetting curve that shows how quickly people can forget events. Another way our memories may be clouded could be by the misinformation effect. The misinformation effect can change the way people remember things. If people hear someone tell a story about an event that happened, they could take that information and believe it’s their own information they experienced first hand. These memory failures cause for controversy over whether or not eyewitness testimony should be used in court. These issues are enough to cause reasonable doubt when trying to convict a person off of an eyewitness account. I do believe their are ways for law enforcement agencies to avoid these issues to strengthen the reliability of their eyewitnesses’

There are many different factors that play a part in the increased chance of a witness correctly identifying a suspect. Such factors should be brought to the attention of the jury and the judge to help in properly assessing whether a witness is correctly identifying a suspect. A study by Magnussen, Melinder, Stridbeck, & Raja (2010) found that of the three different types of people: judge, jury, and general public, that for the most part all where fairly ill-informed on the reliability of eyewitness testimony with judges having the most. Judges only had about an 8% difference in knowledge when compared to jurors. With this information it is very clear that education on the reliability of eyewitness testimony needs to become more of a general knowledge information for the everyone, especially people who are involved in upholding the law. Another factor to look into when evaluating the accuracy eyewitness testimony is the role that memory plays. Memory is divided into three processes: perceiving, remembering, and recalling information (Simmonsen, 2013). There is plenty of room in all three of those stages to forget or falsely remember something. Some factors that play a part when a person perceives an event is the amount of time they are exposed to the event and the suspect. A study conducted by Horry, Halford, Brewer, Milne, & Bull. (2014) found that witnesses were increasingly more likely to correctly identify a suspect if they had been exposed to the suspect for sixty

Eyewitness identification and testimony play a huge role in the criminal justice system today, but skepticism of eyewitnesses has been growing. Forensic evidence has been used to undermine the reliability of eyewitness testimony, and the leading cause of false convictions in the United States is due to misidentifications by eyewitnesses. The role of eyewitness testimony in producing false confessions and the factors that contribute to the unreliability of these eyewitness testimonies are sending innocent people to prison, and changes are being made in order to reform these faulty identification procedures.
