DR JULIA SHAW<\/strong>:<\/span><\/h3>\n\n

MEMORIES ARE OUR OWN TRUTHS\u2026 TRUTHS THAT CAN LIE<\/h3>\n\n

False memories make for thorny debates in research and the courtroom alike<\/strong><\/p>\n\n

F<\/span>alse memories ignite people\u2019s imaginations, particularly when they crop up in high-profile court cases. Such as in 2021, when socialite Ghislaine Maxwell was accused \u2013 and convicted \u2013 of child sex trafficking.<\/span><\/p>\n\n

During the trial, the defence called the most eminent researcher in the field of false memory, Prof Elizabeth Loftus of the University of California Irvine, to the stand. There, she said something that memory researchers say on a regular basis: \u201c[Memory] doesn\u2019t work like a recording device\u2026<\/span> We are actually constructing our memories while we retrieve memories.\u201d <\/p>\n\n

But a statement that in a university lecture hall would simply be taken as a scientific fact, is often decried as unethical during a trial. Why is it that, in the courtroom, experts like Loftus often come under attack, accused of undermining witnesses? <\/p>\n\n

False memory is the term given to recollections that are either partially or completely incorrect. <\/p>\n\n

We all have memories that are flecked with false details: memories where we get our own ages wrong, or remember a friend coming to an event they didn\u2019t actually attend. It\u2019s even quite common to \u2018steal\u2019 entire memories, particularly from siblings. <\/p>\n\n

In criminal justice settings, the same processes can involve a witness misidentifying a perpetrator or misremembering important details \u2013 even an entire crime. False memories are not deliberate lies, but unintentional subjective realities. False memories are our own truths. <\/p>\n\n

But where do false memories come from? In 2015, I ran an experiment to find out. After three leading or suggestive interviews 70 per cent of my participants developed false memories. Many confessed, in vivid detail, to crimes that never actually happened. Further studies showed that these false memories seemed real to others. Of course, research like this must go through ethics boards, and participants were debriefed. But these studies showed how false memories could be created and whether they can be reliably differentiated from true memories. They might help us prevent false memories from arising in real-world situations where the stakes are much higher. <\/p>\n\n

In a legal setting, false memory experts are typically called to work on cases where elements of an important memory are thought to be false.<\/p>\n\n

Maybe CCTV footage doesn\u2019t match an eyewitness\u2019s account, or someone asked to identify a suspect goes from being unsure to very confident. The question for the expert witness is whether these mistakes could be due to false memories. Educating police, jurors and judges on how memory works should enable them to better differentiate between high- and low-quality (or even impossible) memory evidence. <\/p>\n\n

Although I have been hired by the prosecution, as an expert I have most often been hired by the defence. This is because of how the burden of proof works. The defendant\u2019s lawyers want to introduce reasonable doubt, and calling into question how witnesses remember events is one way to do that. <\/p>\n\n

Within memory research, there are also heated debates. Who is to say what counts as a false memory? <\/p>\n\n

\u201cMemory researchers have long accepted that false memories exist, even in normal brains\u201d <\/em><\/strong><\/span><\/p><\/blockquote>\n\n

I have argued that only individuals themselves can know if a memory feels real to them, but other memory experts think that only researchers can spot a false memory. Such arguments have led to instances where false memory experts hired by the defence and the prosecution end up battling out their scientific disagreements in court, making it all seem more confusing than it really is. Memory researchers as a whole have long accepted that false memories exist, even in normal brains. <\/p>\n\n

But in cases where memories are the primary evidence, including in cases involving sexual assault where there is no physical or CCTV evidence, the stakes are high and emotions even higher. <\/p>\n\n

Researchers like Prof Loftus and myself move between two worlds: the scientific world, where facts triumph, and the judicial world, where \u2018legal truths\u2019 triumph and the only thing that matters is what can be proven in court. <\/p>\n\n

Why do we bother? Most of us became interested in false memories because of cases of wrongful conviction. It makes a lasting impression to see a victim point with certainty at a suspect, only to realise years later that the person they helped imprison was not the perpetrator at all. As false memory experts, our job is to help prevent unreliable evidence from contaminating the justice system, one tiny courtroom lecture at a time. <\/p>\n\n
