Study Finds How Easy False Confessions May Be to Obtain

prisoner behind barsYou might think you’d never confess to a crime you didn’t commit, but a growing pile of evidence suggests otherwise. According to The Innocence Project, an organization that uses DNA evidence to exonerate convicted felons, about 30% of their cases involve false confessions. The case that came to be known as the Central Park jogger case, in which a woman was raped and left for dead, was one such case that involved a disproved false confession. Confessions are compelling evidence for juries, even when suspects retract their confessions.

A new study published in Psychological Science, though, suggests that confessions might not mean much, and points to the circumstances under which police officers can extract false confessions.

Recipe for a False Confession

Researchers Julia Shaw and Stephen Porter began their project by recruiting university students and then contacting their primary caregivers. The caregivers completed questionnaires about the students’ behavior between the ages of 11 and 14, and were told not to discuss the surveys with the students. After reviewing the surveys, Shaw and Porter identified 60 students who had not had any involvement with crimes commonly associated with false confessions. They then brought each student into the lab for three separate 40-minute interviews, each separated by about a week.

During the first interview, researchers discussed two events with the student—one that was manufactured and one that actually happened. Researchers used data from the caregiver surveys to incorporate details that actually happened into the story of the event that never occurred. This scenario is common during police interviews that yield false confessions, since interviewees may be asked for details about things that actually happened. In half of the interviews, researchers brought up a crime that never happened, such as a theft or assault, while in the other half, researchers mentioned an emotional event, such as a dog attack.

The interviewers encouraged the students to share details about the false event, prompting them to try even when the student insisted the event never happened. In subsequent interviews, researchers again asked each student to recall the false event in as much detail as possible. Seventy-one percent of the 30 participants who were told they committed a crime as a child eventually developed false memories of the event, while 76% of students given details of a false emotional memory eventually developed false memories of the incident. Eleven students—a third of the false crime group—even reported specific memories of their interactions with police.

It’s easy to conceive of memory as a kind of virtual tape recorder, but the reality is that memory is fallible, flexible, and highly suggestible. This research suggests that a few hours and a few accurate details are all it takes to extract a false confession. In real life, interviews with suspects often last for entire evenings and occur under immense stress, perhaps further increasing the likelihood of a false confession.

While false confessions are common with a number of crimes, these confessions are especially disconcerting in death penalty cases, where a false confession can cost a person his or her life. One recent study found that 4%—or about one out of 25—of those sentenced to die are innocent.

    Well this is not good at all! I wonder just how many false convictions there have been form people who have been coerced into making a “confession” that really isn’t the truth?

    This is unbelievable!I thought there is no big an evidence than a confession to term someone guilty but seems like I was wrong the whole time.If a few details of the past and a little time is all that it takes to obtain a false confession then I don’t know what we are going to do about this when it comes to law enforcement!

    Kind of scary how easily anything can be turned to meet the expectations and desires of others

    Herein lies one of the reasons those frequently targeted by police, namely poor people of color, may “resist arrest.” Instead of quietly complying without complaint.

    They know all too well the likelihood of coerced confessions and other manipulation of evidence.

    They know all too well how juries of more privileged people can easily have their misconceptions stroked by smooth tongued prosecutors.

    And know all too well how court appointed public defenders mostly serve the interests of this adversarial justice system. And not the broader needs of justice which correlate with systematic disprivilege and poverty.

    The numbers are scary, that there could potentially be this many false confessions, but what else are you supposed to do?? You are trying to build a case and reach some resolution for the victim and his family so you have to rely on the information that you are given.

    I guess that I have never been in this particular situation but I find it hard to believe that there was anything that could be s=done to make me confess to something that I was not responsible for. Well, maybe torture but not so much just the power of suggestion
