Game Theory - L.A. Noire: The Human Lie Detector
Can playing LA Noire make you into a human lie detector? Yes! Become an expert on body language with the help of MatPat and some special guest appearances!
Great show as always, but body language isn't really something that can be summed up in 5 minutes, and it's not an exact science - there are plenty of factors to take into consideration. You shouldn't rely on only one signal. You should take into consideration the "cluster" of signals (at least 3 if possible), the situation and environment, and the person you are communicating with (their culture and upbringing, etc).
Not only is culture a huge factor in body language, but it also changes from person to person. Some people may just act a certain way normally, that would be otherwise seen as suspisious behaviour when exhibited in someone else. A baseline needs to be established for each individual. What they do when they tell the truth, and what they do when they lie. Thus you can keep an eye out for that cluster of signals for that particular person.
The eyes aren't that reliable either. Considering a lot of attention is focused on the face, that's usually the one place people try to hide their deceit. Liars may just as well look at you the whole time--trying not to look away--in an attempt to fool you into believing them (hey,, they didn't look away so they can't be lying, right?). Truth is, most people don't make eye contact constantly, they actually spend more time looking elsewhere. And they tend to face diagonally rather than squared up to each other. Being squared up to someone usually makes people uncomfortable, and could be considered a challenge/threat.
As mentioned before, most people are aware of eye-movement and facial expressions, so they try to disguise these things the most. In doing so they usually forget about the rest of the body. In fact, the further away from the head you get, the more likely you are to see the truth. A person may try not to cross their arms or look away when lying, but they may be crossing their legs and be leaning away from the other person, being defensive in other ways other than crossing arms.
Anyway, L.A. Noire is based on real body language, but there will obviously be problems because they are just actors. It is hard to fake these things because our body does them automatically without us thinking about it. Then there is the problem of it being simplified and exaggerated for the average gamer. Actors (or animators like myself) who study body language for a living are going to have a much easier time with the game than others.
That was cool, would of been nice if you touched on micro expressions and some of the technical aspects of lie detection. You got pretty technical in a lot of previous videos but I guess you opted for some more live experiments in this one which was nice. A little balance between the two would of been good.
dude you are awesome no lie.
Awesome episode! I actually liked L.A. Noire and actually haven't completed it 100% correctly! Now I feel I can beat this game easy! Thanks, Game Theory!
This is indeed a very valuable episode, but I do find one issue with pulling out the truth out of someone: How would you be able to concentrate on the subject in order spot and register these signals quick enough without making yourself seem too obvious? Sometimes the subject's expressions may be that subtle?
And if/when they do notice your intense concentration, so many More factors come into play, particularly how well calm and collected the subject gets when they feel someone is breaching their personal bubble. What you may be assuming as a lie when they look the other way, may actually be the truth, but an instilled stimulus inside them instructs them to look away when uncomfortable. For example, I can't help but giggle when someone is looking at me (guess that's why I suck at staring contests).
My only guess is that this why poker glasses come in handy to hide your gaze and thus hiding your intentions, but even that can only go so far without further self-awareness and sensory training from both you and them (which you have to guess as well if you don't know them on a personal level along with the other facts that might help out in your case).
Name of the game show theme: Greed
why did you have to reverse your left and rights to the interrogator's perspective which has no relevance to the questioned person's dominate hand just to make this shit confusing and unfollowable?........
It's not a lie if you believe it when telling it. Also, I'm a lefty, but i always look up when recollecting something, or do I. I've never noticed.
Such, such such a good show, love your work man!! keep it up!
For your bonus points the theme in the background during the LA Noire segments was from the 2002 game show Greed. I might be wrong on the year.I did really like LA Noire though. oh and the Transvestite at 46 seconds was Dr Frankemferter from The Rocky Horror picture show.
Great episode. Its surprising what you can learn through simple movements of the face and arms. I can't wait for the episode that teaches us how become a spy, lol.
Well, I do have a theory (Not a game one, sadly). His eyes did a quick jut to the left BEFORE stating "One truth, one lie." Perhaps, or I am a jerk for stealing someone else saying that before me...
This is really cool :)
Love this show
Great touch ending the show with Tell Me Lies from Fleetwood Mac. This show is awesome!
Eyebrow twitch when he said "boobs" could be some kind of indication of a lie.
The lie was that there was 1 truth and 1 lie...
If the next episode was about the LoZ AND boobs then my life would be complete.
I approve of this
Princess Zelda boobs? and how link wants them?
Kids also are more easily intimidated and get confused under pressure. That's when body language doens't always indicate a lie OR a truth 100% :)
Great video though, body language is an interesting thing and it's kinda cool that there's at least one game out there that actually utilizes your skill in picking up these signs.
