This myth is still being bandied about by “experts” in fields from management to law enforcement. The myth is that if a right-handed person looks up and to the right while speaking then they are lying. To the left, they are telling the truth. This scientifically controlled study, however, showed no relationship between lying and eye movement. Further, interviewers coached in this right/left theory were no better in detecting lies. The best indicator was “excessive” hand movement.
But even then, how would you know what normal hand movement is for the particular person in front of you? Some people gesture a lot, some don’t. Does that mean people who dramatically gesture are lying all the time? Of course not.
Lucky for me, when I’m searching my brain for a fact or figure while I’m talking, for some reason I glance up to the left. It just feels like there’s more there than on the other side (or I like to kid myself, anyway) And I’m right-handed. Since all of this is public knowledge, then anyone intent on getting away with lying could just change the cues they give you. Even lie detector tests can be defeated. The only reliable test is to verify, verify, verify.
