Court TV Host: Can you spot a liar? That's the question behind Court TV's new game show Fake Out, premiering Wednesday, Oct. 1, 8pm ET/PT. Fake Out's host, former FBI profiler Jack Trimarco just appeared on Catherine Crier Live, and we're going to be chatting with him soon.

Question from fortyseven: Have you analyzed any of Scott Peterson's interviews with the media? To me they seem to be textbook examples of how to lie and look obvious doing it.

Jack Trimarco: I can say that many months ago, when Scott was in LA during his press conference prior to his arrest, he made the comment that it was okay for the media to vilify him, as long as it got Lacy's photo circulated. And to me, that was a red flag, because the purpose should have been 'to get my wife back to me.' not to get her picture circulated. That's a peripheral. That certainly bothered me back then.

Court TV Host: Couldn't it be interpreted that "getting her picture circulated" was what he viewed as helping to get her back?

Jack Trimarco: In a roundabout way, but his first response should have been, 'as long as it gets my wife back to me.'

Question from brit: What are the obvious signs of lying?

Question from molly: What is the biggest tip off that someone is lying to you?

Jack Trimarco: Well, depends on the mode of lie detection. If we're using a polygraph, which of course is the most accurate form of lie detection, we're monitoring respiration, sweat gland activity, and cardio function and of course, deviation from the individual's norm in those three components. If we're attempting to detect a lie based on body language, probably one of the most dependable signs is when a person covers their mouth, goes to their face, or in some way obstructs their view to the target of the lie. These rules are only applicable if it can be determined that that is a deviation from THEIR norm. Lastly, if the verbiage and verbal content is being analyzed, then the most common sign that I hear is when a person repeats the question back to me. Such as, I say, "Did you rob that bank?" and they say, "Did I rob the bank?" And that gives them the time to formulate an appropriate response. It takes some effort to lie, and takes time to formulate that lie, so that person's thinking what do I say, or what would an innocent person say if they were in my position.

Question from molly: What is the best way to become proficient at spotting liars?

Jack Trimarco: That's a great question. I would suggest that the person interested enroll in a school or perhaps a university, as several psychology courses are geared if not specifically, peripherally, to that subject matter. Additionally, there are several books on the market regarding lie detection in all of its forms. Or Watch Fake Out at 8 p.m. ET/PT on Court TV.

Question from maria: Is there such a thing as an "expert liar"?

Jack Trimarco: Well, there are certainly people out there who are better liars than others. And it's because they get a lot of practice at it. Some people lie to get out of trouble, some people lie to people that love and trust them, some people lie about really important things, and those are the people that are considered "hard core" liars. Many people, however, lie to keep from hurting other people's feelings. And those are the type of lies that I attribute to "good people". It's the "bad people" that lie about those other things, and lie about things they don't have to lie about.

Court TV Host: One person has suggested one place to go to find "expert liars."

Question from magnolia: Go to political conventions.

Jack Trimarco: Well, I think it would be naive of us to believe that a percentage of politicians don't lie. Politicians are going to say things that are going to get them elected, even if they don't believe it. And salesmen who work on a commission are going to say what they have to say to make the sale. And a large percentage of all people are going to lie when confronted with an authority figure, be it mom, police officer, or the boss, when they've made a mistake. Most people react by telling a lie, even though we don't like to admit that to ourselves. Because it really takes courage to tell the truth under those conditions.

Question from indnsluvr: I was wondering if Mr. Trimarco's "techniques" work on sociopathic-pathological liars who seem to be able to pass traditional electronic lie detectors?

Jack Trimarco: The sociopath - let me address that. In order for a polygraph to be valid, something must be at stake. Most people believe that the sociopath can "beat the polygraph", because they've got no guilt about what they've done. But the polygraph isn't measuring guilt, it's measuring whether that person knows they're lying or telling the truth. And of course the sociopath is only interested in themselves; they're not worried about senior citizens who've lost their pension funds from the fraud perpetrated by the sociopath. The only person the sociopath's concerned about is his lifestyle and well being, not the consequences to his victims. So when the sociopath takes a polygraph, he has a grasp of reality, certainly has something at stake, vis-à-vis jail time, and he knows jail time is not quality of life for him. So the sociopath becomes an excellent examinee for a polygraph examination. Plus, most sociopaths will take the polygraph because their ego tells them they're smarter than the investigators and smarter than the polygraph examiner.

Question from freebe: Do women lie better then men?

Question from Martha: Who lies more, men or women? Is there a type of personality more prone to lie?

Jack Trimarco: Men lie to make themselves feel better. Women lie to make others feel better. And generally, and there seems to be no differentiation between the sexes, all people have the initial instinct to lie to get out of trouble. The reason is that when we were young, we learned that sometimes we lied and got away with it, and thus there'd be no punishment. It's my belief that parents' role in correcting children who lie can't be overemphasized. I've always told my children that it's wrong to lie to people who love and trust you, because you've not only lied to the person that loves you, but you've betrayed their trust. The love will always be there, however, sometimes the trust is gone forever.

Question from Trisha: Jack: My question relates to how corporations can use your methods in their evaluations of potential employees. It appears that many interviewees misrepresent themselves.

Jack Trimarco: Probably the most blatant example of applicants misrepresenting their past or abilities is on the job application form. Sadly, the best way to weed out these misrepresentations is through a thorough background investigation. The employee polygraph protection act prohibits polygraph testing for most job positions. Exceptions are law enforcement, government, etc. Therefore, it is incumbent upon corporate employers to confer with behavioral scientists regarding tests that can be done to determine truthfulness that do not fall under the Employee Polygraph Protection Act.

Question from SwissMrs: I am really excited to watch "Fake Out" How/Who came up with the idea to do the show?

Jack Trimarco: Two brothers out of the Chicago, Jon and Charlie Siskel approached me about nine months ago, and we discussed their ideas, and I'm happy that I got involved in this endeavor, as we're not teaching people how to lie, but teaching people to know when someone's lying to them.

Question from Rosemary: Jack, good luck tonight from me,Connie, Joe and the entire family. Remember your Ringwood roots. I"m not lying when I tell you I wanted you for a brother-in-law.

Jack Trimarco: Rosemary, I just got goose bumps and a flood of memories. Good memories, of the Walker family. Contact me, and let me know what everyone's phone number is. Hope all are well.

Court TV Host: Thanks for being our guest online. Good luck with the show, and we hope you'll come back again to chat!

Jack Trimarco: Thank you.
