There is no one “most common” reason for a false confession, as the reasons for false confessions can vary widely from case to case. That being said, research has identified a number of factors that may increase the risk of a false confession, including:

Coercive Interrogation Tactics: Interrogation techniques that are designed to pressure or intimidate a suspect may increase the risk of a false confession. This may include tactics such as prolonged questioning, sleep deprivation, or the use of physical force.

Lack of Legal Representation: Suspects who are not provided with legal representation during interrogations may be more vulnerable to making false confessions.

Mental Impairment: Suspects who are experiencing mental health problems, are under the influence of drugs or alcohol, or have cognitive impairments may be more susceptible to making false confessions.

Lack of Understanding of the Legal System: Suspects who are not familiar with their rights or the legal system may be more likely to make false confessions, especially if they are not provided with legal representation.

Youth: Research has shown that young people (particularly those under the age of 18) are more likely to make false confessions than adults. This may be due to a lack of experience with the legal system, an inability to understand the consequences of their actions, or a desire to please authority figures.
