Hi, everyone. Sorry I didn't respond in a more timely way. It was very cold yesterday and my main computer is in my basement office. And there was the little matter of the AFC conference title game yesterday, a national holiday in my home town. I can't copy and paste from the iPad so I decided to wait until today until I came into the "office" office.
Statement analysis is not junk science; it is used by the FBI and many other LE agencies. I know a number of people who have been trained to use it, most often in response to live interviews. It is really based in large part on linguistics (which I teach), focusing on word meanings and choices, sentence structure and other aspects of speech and writing that may be largely unconscious to the person doing the speaking or writing.
For example, a kid breaks a lamp while horsing around indoors. The mother sees it and asks what happened. The kid responds in the passive voice: "The lamp was broken." The kid doesn't say, "HMMM, use passive voice to avoid responsibility." It's just how people unconsciously phrase such a statement when they don't want to say who did it. It is used more consciously by PR people who construct "apologies" or "explanations" for bad behavior that actually say the person wasn't responsible for anything, e.g., "I am sorry if people were offended," which shifts focus to the reaction, not the initiating action.
Anyway. Here is a link to Mark McClish's site, which is great and full of information. The analysis I did on Cox is in the Cox thread. McClish looked at the information and said I was on the right track. Written language is less spontaneous than speech, but while people can try to revise and craft and sculpt to control their meanings, syntax particularly is mostly unconscious, in particular the relationship between syntax and thought. Even people who try to control what they write give away much more than they think, which is why getting a letter from a suitor often ended in a break-up for me. I can see too much.
This stuff is not admissible in court, any more than body language analysis or a veteran detective's gut instinct is admissible. But it is a powerful investigative tool, suggesting points for interviewers and detectives to follow up on. If what we want to know is where Cox is lying, hiding information, being deceptive, or trying to manipulate, this is a tool we can use.

The majority of the Statement Analysis techniques are based on word definitions. Every word has a meaning. When you combine this with the fact that people mean exactly what they are saying, it then becomes possible to determine what a person is telling you and if the person is being truthful. Look at the following statement which was given during a job interview. Is this person being truthful or deceptive?
"You know, I am trying to be as honest as possible."
In this one sentence, there are three things which tell us what this person is saying.
The subject starts off saying "you know." The subject expects us to take for granted that he is being honest. The problem is he has not told us he is being honest. He did not state "I am being honest." He states "you know" but we do not know. We cannot believe he is being honest unless he tells us he is honest.
The subject goes on to say, "I am trying to be as honest as possible." The word "trying" means attempted, failed, didn't do it. The subject is clearly telling us he is not being honest. He is only attempting to be honest.
He ends his statement by saying "I am trying to be as honest as possible." The words "as possible" mean the subject has a limitation to his honesty. He can be honest up to a certain point. Apparently at this point in the interview he reached his limitation.
When you first glance at this statement, it appears the subject is sincere and being forthright. However, upon close examination of the words he uses we see that he is being deceptive and that he is not very good at it. Even though he wants us to believe he is being truthful, his language clearly tells us he is not being honest.
McClish has worked as a federal agent in the Secret Service and as a US Marshall. He's not a "psychic" or medium or some other paranormal investigator. He doesn't get into handwriting analysis, but that, too, has a long provenance in investigative circle. Anyway, what I think is on the Cox thread, from work I did on his letters in 2009. I am not a professional at statement analysis, but I have a Ph.D. in English and teach linguistics, not a certificate from the psychic hotline.
