Is deceit a product of evolution?
Saturday, December 27th, 2008Well, apparently so. Take this as an example of such. A young baboon is chased by an enraged mother, intent on dishing out punishment for some infraction within the troop. Suddenly, the youngster stops dead in his tracks, stands up and begins to scan the horizon intently. It is a look that forbodes an imminent attack by outsiders and conveniently distracts all the other baboons, including the mother, long enough so he can make his escape. Deceitful behavior has a long, long history or so the evolutionary biolgists would say. The more sophisticated the animal’s brain, the more commonplace is cunning and guile. Within the primate world, the larger the neocortex - that “new,” more highly evolved portion of of our frontal brain - the greater the capacity to lie, cheat, bluff or swindle the unsuspecting. It’s little wonder we are drowning in our Bernard Madoffs and Rod “Potty Mouth” Blagojevichs.
If that’s the evolutionary case, is it inevitable that lying and scheming are day-to-day activities for humans? Alas, it seems to be. Recently, researchers at the University of California at Santa Barbara conducted their own unique experiment. They asked 77 college students and 70 people from the community to keep anonymous diaries for a week and note the reasons behind each and every fabrication they told. The researchers found that college students told an average of two lies a day, community members one and that most lies fell into the minor “white lie” category. Most were in the “check’s in the mail” variation. A follow-up questionnaire delved into their most grievous lies. Of course, as you well might expect, these had to do with adultery, defrauding an employer or lying under oath to protect someone else. Many carried guilt with them as a result but a surprising number of the guilty realized that they had gotten away with it and felt empowered to do it again and again and again.
The sad fact is this: as humans, we simply are not equipped to detect lies and deceit. Numerous other studies have documented the pitiful inability for a person to detect lies when viewing someone on videotape. Is that person telling the truth or engaging in falsehood? Subjects guessed correctly about 54 percent of the time which is pretty much like flipping a coin or pinning the tail on the donkey. But we as humans are not the only ones who engage in such widespread deceit. It’s just that we are the worst at detecting those lies. Do we have some inbred desire to be deceived at our own expense?
