Eyewitness accounts are crucial in court cases but how reliable are people's memories? Forensic psychologist Professor Fiona Gabbert researches the reliability, suggestibility and fallibility of memory to discover how errors are made. And while most people think their memories are their own, social influences can cause "memory conformity" when people discuss their shared experiences together. Fiona's research leads to tips on how to cue up the brain to improve how memories are made. Programme image courtesy of Sarah Grice, Wellcome Collection.
