Welcome to the Statement Analysis website. My name is Mark McClish. I am a retired Deputy United States Marshal with 26
years of federal law enforcement experience.
From 1991 to 1999, I taught interviewing techniques at the U.S. Marshals Service Training Academy which is located at the Federal Law Enforcement
Training Center in Glynco, Georgia.
During my nine years teaching at the Training Academy I conducted research on deceptive language. Based on my findings, I developed techniques to determine if
a person is lying or telling the truth by analyzing the subject's language.
I call my method for examining a person's words Statement Analysis®.
Statement Analysis is the most accurate way of determining if a person is lying in a verbal or written statement. A person cannot give a lengthy deceptive statement without revealing that it is a lie. This is because people's words will betray them. There are usually several ways you can phrase a statement. People will always word their statement based on all their knowledge. Therefore, their statement may contain information they did not intend to share. Even though people may want to withhold information, they will give us more information than what they realize. Unfortunately, they sometimes give us more information than what we realize. The key is to listen to what people are telling you and to know what to look for in a statement.
This site is intended to serve as a review for those individuals who have attended one of my seminars, read one of my books, I Know You Are Lying and Don't Be Deceived , or have completed my online training course. For those of you new to Statement Analysis, reading my analysis of some famous cases in the news will familiarize you with some of the techniques.
I currently give seminars and presentations on Statement Analysis which are offered by my company Advanced Interviewing Concepts. I also speak at conferences and give presentations to agencies conducting in-house training.
An online program that will analyze a statement for you.
