Article: Memory on Trial

How much can we trust what we remember? For decades, our legal systems have placed immense faith in the testimony of eyewitnesses. We assume that if a person sees an event, their brain registers a permanent record of what occurred, which can later be retrieved intact.

However, cognitive scientists argue that memory is not a pristine archive, but a highly malleable reconstruction. A nationwide survey highlighted the vast gulf between public perception and scientific consensus on memory reliability:

• When asked if they agreed that "once an event is experienced, the memory is permanently recorded in the brain exactly as it happened," 68% of the public strongly agreed or agreed, compared to 0% of cognitive psychologists.
• When asked if they agreed that "an eyewitness's confidence in their testimony is a direct indicator of its accuracy," 55% of the public agreed, whereas 94% of experts disagreed, noting that confidence is easily manipulated after the fact.
