Доверие к очевидцам может сигнализировать правду

In 1998, a Dallas neighbor’s unwavering certainty about a suspect’s identity helped convict a man who was later exonerated by DNA.

The Flores Case Revisited

Jill Barganier, the neighbor of Betty Black, first identified a white, long‑haired driver—Richard Childs—after a burglary‑turned‑murder. A month later she was called back for a forensic‑hypnosis session, during which an officer suggested that the passenger might have “neatly trimmed” hair. Barganier again described a white, long‑haired man and helped police create a composite sketch that bore no resemblance to Charles Don Flores, a Latino, short‑haired man who had been seen with Childs.

When a second photo line‑up presented Flores alongside five other Latino men with short hair, Barganier rejected all of them. Yet, in March 1999, she testified that Flores was the driver, claiming she was “over 100 percent” sure. Without DNA evidence linking Flores to the crime, this testimony became the prosecution’s linchpin, leading to a capital‑murder conviction and a death‑row sentence.

What Confidence Really Means

For decades, psychologists like Elizabeth Loftus warned that memory is malleable, and law‑enforcement line‑ups can implant false identifications. Yet recent work by researchers such as John Wixted and Gary Wells argues that confidence, when coupled with a negative line‑up, can be a surprisingly reliable marker of accuracy. In the Flores case, Barganier’s initial rejection of the line‑up—despite her later certainty—fits this pattern: the witness’s confidence grew only after she was presented with a lineup that excluded the true perpetrator.

Laboratory studies now show that witnesses who confidently reject a lineup are more likely to be correct than those who accept a suspect. The key lies in the witness’s internal monitoring of memory fidelity; a confident rejection signals that the memory is vivid and uncontaminated.

Implications for the Justice System

If confidence can be a diagnostic tool, courts must rethink how they weigh eyewitness testimony. Some U.S. jurisdictions are already adopting procedures that record witness confidence and treat negative line‑ups with greater scrutiny. However, the criminal‑justice system is notoriously slow to change, and the weight of eyewitness evidence remains high.

Wixted is preparing a petition to the U.S. Supreme Court to reconsider Flores’s conviction, arguing that the new science invalidates the reliability of his testimony. Should the Court accept, it could set a precedent that forces prosecutors to document confidence levels and to treat negative line‑ups as evidence of innocence.

In short, the Flores case illustrates that eyewitness confidence, when interpreted correctly, can be a powerful ally in the pursuit of justice—challenging the long‑held belief that memory is inherently unreliable.
