Psychology of Interrogations, Lie Detection & Forensic Linguistics

An interrogation is a negotiation about the truth. Besides physical evidence, interrogations & witness interviews are the most important source of information. The goal is not to get a confession at any price, but to get to the truth. The Psychology of Interrogations and Detection of Deception are basic skills for Police & Intelligence to build trust, to spot a liar and to get infomation.

Mark T. Hofmann is a Crime- & Intelligence Analyst, trained and certified in the United States. He is a university lecturer for Behavioral- & Cyber Psychology and has met criminals, psychopaths, and hackers to research the inside perspective. He is in expert in Profiling & psychological methods. His approach and training on The Psychology of Interrogations & Deception Detection is based on three key elements:

1.Building trust and willingness to talk: This is mainly about the psychology of trust, but also time and location/room can have an effect.

2. Detecting deception: This is mainly about methods of Forensic Linguistics and Statement Analysis. Body language is completely overrated, language is much more important.

3. Getting to the Truth: Using lawful Interrogation- and Questioning Techniques and the Strategic Use of Evidence (SUE) to get true confessions.

“Body language is completely overrated. You can see that someone is getting nervous, but not why. However, there are scientifically sound methods to detect deception and to get to the truth. Forensic linguistics play a key role.”

up to 85.4% is the success rate of getting to the truth when police officers have been trained in the Strategic Use of Evidence. So there is hope, but it has little to do with body language.
