It has become evident from various studies that "sleep deprivation adversely affects decision making", including survey results on sleep by the American Centers for Disease Control and Prevention (CDC). In addition, there is also evidence that most cases were recorded at the time of listening to circumstances carried out for more than 12 hours, in cases where it was found that confessions were incorrect at the police interview.

At the University of San Francisco and Northwestern University, in order to investigate the relationship between sleep deprivation and wrong confession, we conducted experiments to make decisions in the state of sleep deprivation. Collected 88 subjects and asked two types of tasks using PC for 7 consecutive days and asked the subject "Please do not press the ESC key of the keyboard absolutely during task execution, otherwise The important data of the experiment will be lost. " The Esc key is located in the corner of the keyboard and it seems that it was chosen because it has low probability of accidentally pushing. After completing the task, the subjects were divided into "Group A" sleeping for 8 hours and "Group B" waking up all night.

The next day, before the subjects returned home before the subjects returned, "You pressed the Esc key during the yesterday 's experiment, please sign the document if you accept your own mistake", the experiment organizer told the subjects That's right. About 18% of subjects in group A who took sufficient sleep was admitted to mistake, but in group B 50% of subjects accepted mistakes. In addition, the same thing was reported again to the subject who did not recognize the mistake, and the reaction was observed. As a result, 38% of group A and 18% of group B recognized mistakes, totaling 56% in group A, In Group B, 68% of subjects made a wrong confession.

Based on the experimental results, the research group speculates that "the probability that mistakes will be made more improperly in everyday life as sleep tends to be insufficient." For that reason, the research team insists that "police interviews should record all the scenes and prove the legitimacy of confessions." It also states that it is important to measure whether a suspect is taking enough sleep even when a suspect signs on a letter admitting confessions.

For the reasons why the proportion of subjects who confirmed mistakes exceeded 50% in both groups, the research group said, "Since the penalty was not imposed by recognizing mistakes in this experiment, subjects obediently accepted mistakes I made a confession of lies, "he commented on the shortcomings of the experimental content. Also, the wrong confession may also be affected by individual personality differences, and experiments have also revealed that "people who are easy to make impulsive decision making has a high probability of making a wrong confession" .
