A lot of people like to think they know other people, that they’re adept at detecting deception and above being fooled. I always cringe when people recite that drivel about how people’s eyes move “up and to the right” for the truth and “down and to the left” for a lie, or whatever they say it is. I remember very clearly when I was in college, one of my psychology professors telling the class that this was patently false. Directionality of gaze was not so much the issue; rather a person averting their gaze in general, or being unable to look someone else in the eyes, could signify deception.
Then again, it could signify a lot of things; distraction, feelings of inadequacy or shyness, feelings of guilt (unrelated to lying.) Plus, anyone who’s ever been done dirty by a spouse or best friend could probably tell you it’s completely possible for a person to look you square in the eyes and lie to your face.
Of course, I’m digressing, as usual. The point is, a lot of the so-called clues to detecting when someone is lying to you, seem, in my opinion, vague and unable to be extrapolated to the majority of people with enough accuracy to be conclusive. That may read like a mouthful, but all I really mean is that these “tells” don’t occur with enough consistency or reliability to be useful in most situations. There are too many variables, and unless you are the type of person who likes to take chances with your relationships, you don’t want to accuse someone you care about of lying unless you’re damn sure.
Perfect example; I’ve seen it mentioned before that people who qualify their statements with remarks like “To tell you the truth,” “Frankly,” and “To be honest,” are actually unconsciously cuing you to the fact that they are about to lie to you.
Am I the only person, then, that regularly uses those expressions…and then proceeds to do exactly that– tell the truth? I can’t speak for everyone, but when I use that phrase, it usually means that what I’m about to tell you will either seem A) surprising/unexpected coming from me, or B) that what I am about to say is going to be the truth, but perhaps an unpleasant truth.
Anyway, I’m definitely not disputing that there are often physiological and physical signs present when a person is lying. However, I think these signs need to be taken in context. The fact that lie detector tests are not considered reliable or accurate enough to be used in court should be at least some indication that many of these signs of deception are not consistent enough between subjects to be 100% reliable. I would guess that some indicators are also more accurate than others. For instance, involuntary reactions like pupil dilation and micro-expressions would likely be a more reliable indicator of deception than a turn of phrase, such as “To tell the truth,” the use of which is subjective depending on the speaker. (For instance, perhaps that phrase was used frequently throughout the speaker’s childhood by his mother, and thus is a learned mannerism and has no bearing on deception.)
I’m sure there are people out there like Dr. Cal Lightman in Lie to Me* (I think they’re called poker players), and I have great admiration for people with that skill set. But I doubt there are many of us regular Joes that can do what Cal does. I’d wager that individually, how effective each of us is as a human lie detector will depend, in one part, on how much we know our subject, and in another part, how observant and aware we are of other people in general.

Tangential to that topic, I’ve heard it said that people who preface their opinions with “No offense intended,” “No disrespect,” or some similar sentiment, are in fact, about to insult you.
This is another blanket statement with which I disagree. It may be true that a lot of people use this phrase as a passive aggressive way to take a jab at someone, but–and again, I’ll only speak for myself here– when I say “No disrespect,” it is often when I know my opinion is directly contradictory to the other persons’s, or when there seems to be no way to stand behind my point without seeming combative. It’s been my experience that some people become almost automatically defensive and even hostile when confronted with an opinion that is very different from their own. Some people take it as a personal affront. If you don’t believe me, scroll through your Facebook wall. I’m sure you’ll eventually find at least one ridiculously hostile argument over politics, religion, sports, or something even less significant.
Anyway, as usual, I’ve sort of taken a short post and gotten way too analytical about it. Thanks for bearing with me and my rambling.
And if you don’t like it, No disrespect, But to be Honest...fuck you. (Just kidding…sort of.)
