A number of factors conspire to erode the truth. From biological realities of memory and the brain’s propensity to fill in gaps with fiction to procedural errors that unintentionally reinforce a false narrative, it’s hard for witnesses to get it right. All the flaws in eyewitness testimony seem obvious, and most of them are. What’s interesting is how long we’ve known and largely ignored them.
More than a century ago, psychologist Hugo Münsterberg wrote detailed essays about the problems with witnesses, including eviscerating his own memory of being a crime victim. And before that, Hermann Ebbinghaus explained the “forgetting curve” that shows how memory deteriorates and how spaced repetition — of both fact and fiction — can cement what’s in our minds.
Despite generations of knowledge about the fragility of eyewitness identification and testimony, there’s still nothing more powerful and persuasive than a witness pointing a finger at a defendant in court. In the end, forensic science saved Ronald Cotton. But for an immeasurable number of victims of eyewitness error throughout humanity’s pursuit of justice, the result has been imprisonment and death — and the truth is that the problem can’t ever be solved completely.
