Repressed Memories and Eyewitness Testimony Reliability
This paper examines the reliability of two major forms of witness evidence in criminal proceedings: repressed memories and eyewitness testimony. It argues that repressed memories, while sometimes rooted in genuine experience, are prone to distortion through hypnotic suggestion, post-event information, and the passage of time, making them unsuitable for admission in court. The paper also contends that eyewitness testimony, though widely regarded as strong forensic evidence, is vulnerable to bias, prejudice, memory reconstruction, and law enforcement pressure. Finally, it offers practical strategies — including repeated interviews, cross-referencing with physical evidence, and eliminating investigator bias — to improve the reliability of witness accounts.

What makes this paper effective
- The paper draws a clear parallel between two types of witness evidence — repressed memories and eyewitness testimony — showing that both suffer from similar reliability problems, which strengthens its central argument.
- It avoids an absolutist position, acknowledging that repressed memories may contain a "core of truth" while still concluding they should not be admitted as courtroom testimony, lending the argument nuance and credibility.
- The paper closes constructively by offering actionable recommendations for law enforcement, moving beyond critique to practical application.
Key academic technique demonstrated
The paper demonstrates the technique of comparative analysis — examining two related phenomena (repressed memories and eyewitness testimony) side by side to reveal a shared weakness. By explicitly connecting the two in its transition paragraph ("in the same way that repressed memories can be false or blurry, so too can..."), the paper creates a unified argument rather than two separate discussions.
Structure breakdown
The paper opens with a focused discussion of repressed memories, explaining why they form unreliably and why hypnosis cannot validate them. It then pivots to eyewitness testimony, covering memory reconstruction and bias before concluding with concrete recommendations for improving reliability. This progression — problem, parallel problem, solutions — gives the paper a logical and satisfying arc suited to a forensic psychology or criminal justice course.
Introduction to Repressed Memories
The controversy surrounding repressed memories has to do with the fact that under hypnosis, an individual might falsely recollect an event or experience. This is because the hypnotherapist could prompt the person — in other words, the individual might feel that they had a memory because they were coached to believe so. Additionally, the life experiences that occurred since the initial memory was formed could create inaccurate recollections. For example, a person might fuse what they saw in a movie with what they actually experienced because they identified strongly with the film. There are many reasons why repressed memories are unreliable, even if they contain a grain of truth.
Validity of Repressed Memories as Forensic Evidence
Such problems should not obscure the fact that repressed memories genuinely do exist. Trauma victims are especially prone to repressing painful memories. What forensic experts need to determine is how valid some of these memories are once they are recalled years later. There are serious problems with using repressed memories as forensic evidence — though this does not mean repressed memories are always false. In many cases, they do represent genuine life experiences. Repressed memories may contain a core of truth, but the details are likely to be false or at least blurry. While hypnosis does have the ability to help repressed memories surface, these memories should not be admitted as testimony in a court of law.
Reliability of Eyewitness Testimony
Eyewitness testimony is generally regarded as high-quality forensic evidence in court. However, in the same way that repressed memories can be false or blurry, so too can the recollection of a witnessed criminal act. Memory is often reconstructed, and it is possible to introduce items, persons, or events that never actually occurred. Research has shown that it is possible to insert new facts into an actual memory, thereby creating new and false memories. The memory might feel and seem real, yet it can be like recalling a television show or a dream. The misinformation effect is a well-documented phenomenon illustrating precisely how susceptible human memory is to post-event contamination.
