When an eyewitness gives evidence in a trial, how much faith should we place in their testimony? At first brush the answer would seem to be, why not trust them? After all, if an impartial witness says with certainly they saw something—why be sceptical?
However, Elizabeth Loftus, a renowned professor of both law and psychology based at the University of California’s Irvine campus, urges caution. Professor Loftus has been at the forefront of complex and controversial debates around the nature of memory for many years, and her research has made her a much sought-after expert witness in both criminal and civil trials. In fact, she has testified in over 250 trials.
Professor Loftus says eyewitness testimony is the major cause of wrongful convictions in the USA. In one project where more than 300 cases of wrongful conviction were established using DNA testing, the major cause of these wrongful convictions was faulty eyewitness testimony.

Others followed in Professor Loftus’ footsteps, conducting experiments that planted more unusual and bizarre memories. A Tennessee study planted a false memory of nearly drowning and being rescued by a lifeguard; a Canadian study found that people believed they had been the victim of a vicious animal attack and an Italian study showed you could get people to believe they’d witnessed people being demonically possessed.
Loftus describes repressed memories as ‘one of the great mental health scandals of the 20th century’.
‘We saw thousands of lawsuits, all that money, all that waste, all that pain. When people have been abused in childhood, their problem is not that they can’t remember, but that they can’t forget.’
