wiki how to detect lies

I found a very nice article on how to detect lies. I will eventually get to making my own article about this... unfortunately I'm very busy at the moment so you'll have to wait.

Indian Interview - body language

Continuing with this video analysis of a Chinese being interview i'm doing a indian. Again i have absolutely no idea what this guy is saying but you will see the same emotions and body language as everybody else.

The video:


1) ~ 00:00:24 / he starts the interview with his hands crossed. in this case it's a comforting gesture he feels safe that way to the upcoming interview /
Photobucket

2) 00:00:40 / looking down and to the right meaning he is experiencing some feelings when talking. a transcript would be nice :) /
Photobucket

3) 00:00:45 / looking up and to the right - visual construction /
Photobucket

4) ~ 00:00:57 / starting being a little bit more happy and confident about what he is saying /
Photobucket
* a few seconds later he crosses his fingers and places them on his knees. crossed fingers represent one of the most confident body movement that i know of.

5) 00:01:22 / slight angry - the brows are lowered and drawn together; vertical lines appear between the brows; the lower lid is tense/
Photobucket
*it's not a full expression of anger and i'm not sure that he is really angry but he is feeling something important(it can be that the expression is of concentration)

6) 00:01:32 - 4 seconds / he takes two deep breath of air and blinks rapidly. he isn't confident or it's something very important to him/
Photobucket
* you can't see the first deep breath but if you look at the video it's a few seconds before this scene starts

7) 00:02:11 - 3 seconds / a very good example of micro expressions. he changes from anger to happiness in just a seconds. you have to watch very carefully to see what i'm talking about /
Photobucket

To Be Continued....

Social Psychology - Stanford prison experiment

Because everything is more easy to understand just watching a video here is a documentary on the Standford prison experiment.



The first time i heard about this kind of experiments is at http://cracked.com 5 Psychological Experiments That Prove Humanity is Doomed.

You should start with what is Social Psychology and a few explication about the Stanford experiment.

Ted has a excellent video of Philip Zimbardo explaining what Social Psychology is about:



Everybody should know something about human psychology. How a individual acts in based upon his social surroundings. As Philip said... while killing is considered a bad think in a normal society it's consider a good think when you're killing somebody in a war.... you're even given a medal for this. Human have double standards for most thing's and for most of they're live aren't in control. I'll explain in what way where restrained by our society in a different post. For know it's sufficient that you learn how to act is situations similar to those showed in the above experiments. Please do learn from the mistakes of others and try to not to repeat them.

Mel Gibson Calls Reporter A**hole WGN-TV - You should have seen it coming

You should have seen it coming. This is what i'm trying to make people learn. It's a video of Mell Gibson taking an interview and at the end he calls the reporter and a**hole. It has some clear indication that he doesn't like what he is being asked. Well you can figure it out just by simply basic deduction but it's nice to see some visual representation of an annoyed person.

This is the video:



1) 00:00:00 - 2 seconds / He slightly brings his face forward. First of all i don't think that there's a problem with his hearing(only in two occasion he does this... in the rest his hearing is fine) and neither with the equipment so this has to be a very important question or interview for him.
Photobucket

2) 00:00:18 - 3 seconds / He rubs his nose which is a classical calming gesture. He is reassuring himself that everything is ok. /
Photobucket

3) 00:00:29 / the same as 1) point... he over emphasize hearing what the interviewer is saying /
Photobucket

4) 00:00:40 / concealed fear expressions - you can see the smile that no problem but it's not a true smile it's hiding a fear expression. you can see the expression in the upper face. the brows are drawn together and raise, the wrinkles on the forehead are in the center. /
Photobucket

5) 00:00:46 / visual remember - eyes pointing on his upper left - he remembering the drinking problem /
Photobucket

6) 00:00:46 - 2-3 seconds / a long scorn - made by his nose - it's a gesture that you make when you don't like something.. similar to disgust /
Photobucket

7) 00:00:53 / he leans forward trying to be in the reported face or trying to be more to his leaved to explain very carefully that the drinking problem happened almost 5 years ago /
Photobucket

8) 00:01:03 - 2 seconds / he takes a coffee cup and crosses his legs; it's a clear sign that he is trying to protect himself from the reporter /
Photobucket

9) 00:01:10 / disgust in his lower face . the lower lip is raised and pushed up to the upper lip / Photobucket

The last think that he does is drink from his coffee while the report is saying something good about Mell. It's a impolite gesture but you kind of get by know that he isn't taking very good to the inappropriate question asked by the reported. In the conclusion you should of seen it coming. celebrities

Chinese interview with Mr. Wong Yuk Man (黃毓民) in Calgary

A friend gave me the idea of doing videos of Chinese people. First of all because i can't understand one word of it and it would be grate to see some emotions on a face that isn't that familiar. It's important to remember that oriental culture is very different from the western one. For example when showed a disgusting video an oriental will not show his emotions in public because it's not customary. Still it will be interesting to see what we can get from a small video.

The video in question is this one:


1) 00:00:04 / defensive stance - he isn't confident about the interview or he is just not comfortable being asked all the question /
Photobucket

2) 00:00:44 - 2 seconds / he gained confidence by being more open to the person who interviews him /
Photobucket

3) 00:00:52 - 5 seconds / he started to gesture about what he was saying /
Photobucket

4) 00:01:03 -2 seconds / a very particular nose pick after settings his glasses. touching your nose is a gesture intended to calm yourself but i never saw it done this way /
Photobucket

4) 00:01:20 / disgust or slight anger showed in the lower part of the face - this face actually means that he is says OK or agrees with someone but he is not satisfied by the situation /
Photobucket

I will do the rest of the video later. I'm running out of videos so i must use my limited resources as much as i can. It's not that i don't have videos but only a few of them so a lot of emotions. And for now i just want to show the emotions on people faces. For example in this video i only seen only one... the rest where body movements.

Heidi Said

I really like this girl. She is always sad or angry or surprised about the world. I consider her my benchmark to compare with other people. Maybe i'm just a sucker for girls with problems. Maybe she doesn't have problems but that's the impression that she gave me.

This is her video:


and this is what i saw:

1) time 00:00:04 / sadness in the brows and the lower face /
Photobucket

2) time 00:00:06 / contempt - usually contempt is registered by a asymmetrical smile /
Photobucket

3) time 00:00:13 / disgust - raising of the chin /
Photobucket

4) time 00:00:51 / i can't see all her face but it look to me that it's a sad face covered up by a smile /
Photobucket

5) time 00:01:20 / a blend with disgust and contempt - disgust by raising of the chin and contempt from a asymmetrical smile /
Photobucket

I found one more contempt at 00:01:27 which i won't cut out.

Chris Matthews Predicts Brown Win part 2

I'm finishing this video



It's very important when you start to detect emotions to have a baseline of how the person looks or stand normally. He may have a back problem and walk leaning forward. If in this case you see him talking with someone it's false to assume that he is interested in the person. As with the face the length or deepness of wrinkles on the face determine in some percentage what the emotions is. With age some faces tend to have more permanent wrinkles so you have to be careful with judging the expression.

It's very hard to find normal faces usually there smiling which makes most of the permanent wrinkles disappear.

Photobucket

and

Photobucket

1) time 00:03:03 / sadness in the lower eyelids , looking down and sadness mouth /
Photobucket

2) time 00:04:49 / happiness in the eyes and in the mouth /
Photobucket

3) time 00:05:28 / slight angry registered by the brown lowered and drawn togheter, vertical lines appearing between the brows and lower lip tense and raised
Photobucket
* The anger emotions has to register on the full face or it can mean something else. You have to take into consideration what he is saying that we see this kind of emotions.
Part of the transcript: "I don't make statements like i don't work in a emergency room if you have a conscience and are for abortions. I mean how do you make statements like that."
We can pretty safely assume that he is angry on the people who say such things.

4) time 00:06:57 / sadness the same as before with a little bit of fear in the forehead. There are horizontal lines only in the middle part.
Photobucket


There are a few more emotions until the end of the video. I should point to two important moments when he beats his lips twice. The first time at 00:07:13 and a second time at 00:07:22 meaning that he is probably anxious or nervous about the statements.

Shoulder Shrug - body movement - tutorial

I have shown a lot of videos in which I have pointed out this subtle body movement but haven't taken the time to explain what dose it mean. The wikipedia article refers to "an exercise in weight training". For detecting lies this sign represent not knowing something.
This is the full body movement: Photobucket which is a pretty common sign. You probably seen it when you ask somebody a question and he doesn't know the answer

It's a general rule in detecting lies and emotions that if something isn't done right or doesn't seem natural it's probably wrong. Although in this example if you ask somebody a question and he doesn't raise his shoulders as up as he can it doesn't necessarily mean that he isn't truthful. It can just mean that for example while he is answering he kind of remembers the answer. Or he/she isn't exactly sure about the answer but choose to answer that he/she doesn't know because they're is in a hurry.

You always have to take in account what the subject of the inquiry is and the situation. This is a word of warning regarding all of the future tutorials. You shouldn't assume anything base upon one or two observation. You should take into consideration a lot of facts before you can say that somebody is lying. There isn't anything that can replace evidence in telling if somebody is truthful or not.


The shoulder shrugs that i have shown you are partial body movement. They usually occur when the person isn't sure about what he is saying.
Here are a few examples from the videos that i have analyzed:

Photobucket

Photobucket

The feeling that i have when I'm doing this is that I'm not comfortable in my own skin. I'm usually well aware of this type of sign's when I'm making them yet most people aren't. I have done a few controlled experiments in which this particular body movement is pretty common. I can't show the videos because the people that i have worked with(usually friend and family) wouldn't be to happy about this. In my experiments i ask the person that i would be interviewing a few question which they can answer truthfully or not. After the interview was over i would go over the question with them and get the sentences that are lies and the one's that are truthful and then watch the videos for sign's of deceit. It's not always a intentional misleading. Sometimes i would ask a difficult question and the first answer wouldn't always be truthful.

Hope this short tutorial was helpful and see you soon when i finish the "Chris Matthews Predicts Brown Win" video.

Conversations with History: Paul Ekman

I'm to tired to write a new blog entry so i'll cheat a little bit.

Here is a video of Dr. Paul Ekman




and a treat... the first episod of Lie to me. It's the TV Series that this blog is dedicated to



Sorry about the subs. This is how i found it.

Explanations and Documentation

       I had a few discussions with the people who can help me get this blog launched and all of them suggested that i should try explaining what i am talking about.

       I can't start to explain and build my tutorials because i need pictures and a lot of materials to illustrate. As all scientific data you shouldn't trust my word. I need facts and observable information. This isn't something new and there are a lot of studies done and i could easily copy someone else's work but that wouldn't help me in any way. I am here to learn as much or probably more than you. Work is the key to success and i need to work a lot to compete with those who are natural or who are doing this thing for a long time. There is a whole system to detect lies and deceit.
       It is generally refereed to as deceit because you can't actually tell if he/she is lying or not. There isn't a clear facial expression for lying. Usually there are contradictions or Freudian slips. For example in the obama post i made i wasn't trying to prove he was lying. It just struck me that for wining the nobel prize he wasn't exactly surprised or humbled or happy or any other expression you would expect. Although i didn't analyzed all of the video it is clear that he is angry or extremely concentrated. The reason for this are multiple and are completely irrelevant.
       Given the fact that i'm half a globe away i couldn't possible find out by future investigation what is the reason for the masked expression of anger. Maybe there weren't any hidden reason he just probably woken up on the wrong side of bed. This whole blog is just and exercise to help us understand and learn through repetition how to better understand human emotions. And if it's the case to help us detect in case of need what somebody is actually feeling.
       You have to remember one thing... and consider this an official warning. Knowing how to read human emotions is like a special power. Don't get me wrong we all know how to spot a surprise face

a happy face

but maybe sometime the people showing a fake smiling face just want's to tell you that he is handling his problems. It isn't always necessary to point out that a person is sad or disgusted. Maybe it's with himself or with something that he remembered while he was talking with you. In day to day communication with friend and relatives it is recommended you avoid or at best be subtle about it.

       Before i will start building the tutorial i will direct you to a few website's that you should read. I'm going to start with a link to wikipedia explaining who is Dr. Paul Ekman and what is his research about. You can find the link here. On the bottom of the page you will find the link to his website. On Dr. Paul's website you will see a lot of reference to a TV Series called Lie to me. Here is the official page. You can find all this link and many more just using google. I'm not doing anything out of the ordinary just pointing you in a direction in case your interested.

       The initial study is about coding the facial movements FACS for short. He wrote a book about this. There is a lot of work just cataloging and coding all of the possible movements yet this is just the beginning to what is ahead. It wouldn't of been possible to continue research without this important step. The next one is determining emotions on the human face. You should take note that this is not the first time that this was researched.

       Charles Darwin and Duchenne de Boulogne both try experiments to determine the fundamental question: are emotions common to all humans? Just a quick reference to Charles Darwins book and to Duchenne work and life

       I will let you read the information i have given you and i will come back soon with a tutorial about shoulder shrug because i have a lot of material and examples regarding this.

Eye Direction and Lying

I will start a series of short tutorial to explain what i'm talking about. I don't know how exactly to do this but i will try to do my best. As everything i will start with little things and go on to bigger things.

First of all a short explanation that has been on the Internet for a long time. You can find it here. I won't copy everything. You can read it at the link.

There are only one thing i consider important that i want you to remember. First of all a image is worth 1000 words.



Meaning:

C = constructed as in Visually Constructed / Auditory Constructed
R = remember as in Visually Remembered / Auditory Remembered
F and I = Feeling / Kinesthetic and Internal Dialog.

Let's put things into perspective.
Let's say your child ask's you for a cookie, and you ask them "well, what did your mother say?" As they reply "Mom said... yes." they look to the left. This would indicate a made up answer as their eyes are showing a "constructed image or sound. Looking to the right would indicated a "remembered" voice or image, and thus would be telling the truth.

Microsoft CEO Ballmer - detecting emotions part 2

This is the video i'm talking about.



I did two posts down a partial analysis. I will continue here. In case you didn't notice i kind of moved a little bit from the realm of emotions. The reasons is that there are such good sign's that i can't resist. But for those of you who aren't familiar with detecting lies i will do a series of tutorial to help you get started.

As for this video this is what i saw:

1) time 00:00:38 / false suprise /
Photobucket

2) time 00:01:15 - 00:01:17 / shoulder shrug and contemp on his face/
Photobucket

3) time 00:01:22 - 00:01:26 / I don't know exactly what happened here. The thing is he isn't that confident about what he is talking about. Is a pretty big issue if iphone will have success or not. This is a body movement. It's like he isn't comfortable in his skin and tries to get out
Photobucket

4) time 00:01:41 - 00:01:43 / shoulder shrug /
Photobucket

And that's it. You be the judge about what he is really felling.

Microsoft CEO Ballmer - detecting emotions

This is the interview after the IPhone was launched:



1) time 00:00:00 / contemp /

2) time 00:00:04 / false smile /

3) time 00:00:12 - 00:00:14 / false surprise /

4) time 00:00:26 / fear /
* i never thought i would see such a emotion so quickly. It's my third video and to see one of the most rarest emotions caught on camera.

5) time 00:00:26 - 00:00:30 / shoulder shrug /
* i will explain in a later post was the shoulder shrug is all about

I will stop here with this video... i have a lot of thing to do. The next post will contain the rest of the analysis. And in the near future i will start posting a little general information for those of you who don't know anything about detecting human emotions.

first video - explanations and tests

So this is the video i am working on. I won't finish all of the emotions because it's a little bit to late in the night but i will do my best to finish it soon.



I'm running on Ubuntu on my home computer that means a lot of free software for me to work with. For analyzing the movies i use Avidemux(GTK). Just type avidemux in your synaptic package manager, install and you'll all set. You can use the key's 4 and 6 to scroll frame by frame along the video. I have a numpad on my laptop so that is a bonus :). Use the key P once to start the video playing and again to stop the video. I'm not expecting everybody that will show an interest in this to use the above program but for the short time i have been using it it's ok and i recommend it.

So first thing is first. The girl's name is Heidi. I don't know anything about why the film was made. I just saw a few feelings showing very clearly on here face and decided to use it. I don't have a method for getting videos. I'm still in the training stage so this for me is a work in progress. I will eventually make my way to more skilled liars: statesmen and actors. For now i will only show emotions and as time goes on i will go to analyze what see is saying in relation to what she/he is speaking.

1) time 00:00:07 / sadness in lower part of face /





2) time 00:00:13 / contemp or disgust in lower part of face /


3) time 00:01:27 / contemp /
*she was talking about living with no electricity so i can understand that


4) time 00:02:43 / contemp /






I can't do anymore. I'm certain that there are a few more emotions hiding there but i am to sleepy to do this properly. I did so a lot of shoulder srub which is a sign of insecurity. For what i can tell she really does believe what she says and of course i don't have any doubt in the first place. But we are here to learn so hope we will do this in the future.

Have a good night and see you soon.
