High confidence in a memory, particularly eyewitness identification, does not reliably predict accuracy — a principle illustrated by the wrongful conviction in the Ronald Cotton case.

The Russian proverb 'the past is more unpredictable than the future' opens a deep dive into eyewitness testimony. The Cotton case is a masterclass in how every favourable condition for reliable memory — prolonged exposure to the attacker, high motivation to remember, strong emotional arousal — still failed to prevent a catastrophically wrong identification. The victim deliberately studied her attacker's face, survived, went to a lineup with the deliberate intent to identify him, and still picked the wrong man. The mechanism: once she made the identification, the selected face replaced her original memory, and every subsequent recollection reinforced the error. Castel contextualises this within the memory contamination framework — memory is evidence, and like DNA evidence it can be contaminated in predictable ways. Cross-race identification compounds the problem. The broader lesson for the courtroom, for everyday arguments, and for learning: confidence is not a reliable proxy for accuracy.
A victim who specifically tried to memorise her attacker's face — under peak emotional arousal — identified the wrong man with total certainty. Once she identified him in a lineup, his face overwrote her actual memory. DNA evidence decades later exonerated the convicted man.
