The human proclivity to deceive and lie is captured in countless cultural products. Songs about lying include Love the Way You Lie (Eminem featuring Rihanna), Little Lies (Fleetwood Mac), Lie to Me (Depeche Mode), Lies (Thompson Twins), Lies (Elton John), and Honesty by Billy Joel. Movies that tackle lying include True Lies (1994), Liar Liar (1997), and The Invention of Lying (2009). Incidentally, I discuss in some detail the latter movie in chapter 8 of The Consuming Instinct when tackling the origins of religion. Speaking of religion, the Bible contains several admonitions against lying including the ninth commandment "You Shall Not Bear False Witness Against Your Neighbor" and Proverbs 6: 16-19 (King James Version) where God's antipathy toward liars is made abundantly clear:
"These six things doth the LORD hate: yea, seven are an abomination unto him:
A proud look, a lying tongue, and hands that shed innocent blood,
An heart that deviseth wicked imaginations, feet that be swift in running to mischief,
A false witness that speaketh lies, and he that soweth discord among brethren."
This leads to the all-important question: how often do people lie in their daily lives? In a paper published in 2010 in Human Communication Research, Kim B. Serota, Timothy R. Levine, Franklin J. Boster tackled this exact issue in three separate studies. For the purposes of this post, I'll restrict my discussion to study 1, which utilized an online survey of 1,000 Americans via the Synovate eNation omnibus panel. Participants were provided with the following description of what might constitute lying:
"We are interested in truth and lies in people's everyday communication. Most people think a lie occurs any time you intentionally try to mislead someone. Some lies are big while others are small; some are completely false statements and others are truths with a few essential details made up or left out. Some lies are obvious, and some are very subtle. Some lies are told for a good reason. Some lies are selfish; other lies protect others. We are interested in all these different types of lies. To help us understand lying, we are asking many people to tell us how often they lie."
Participants were asked how many lies they had told in the past twenty-four hours. Here are some of the key findings:
(1) The average number of lies told per day was 1.65. This strikes me as surprisingly low. I have the feeling that many participants were lying about the extent of their lying!
(2) Only 40.1% of the sample reported telling a lie in the past 24 hours.
(3) 22.7% of all lies were told by one percent of the sample, and half of all of the lies were told 5.3% of the sample.
(4) Subsequent to controlling for various demographic variables, no statistically significant sex differences were found in terms of the extent of lying (men = 1.93 lies; women = 1.39 lies). I should mention that evolutionary psychologists would have predicted this null effect, as one should expect that men and women are equally adept at lying albeit they are more or less likely to lie about sex-specific issues of evolutionary import (e.g., in personal ads/online dating, men lie about their social status while women lie about their appearance; cf. Hall et al., 2010).
This leads me to one final thought. Men, if ever asked the following question by your significant other (female): "Do these jeans make me look fat?" If the veridical answer is "yes," you may wish to exercise your daily quota of lying in offering a response.
