Adult Dishonesty May Lead Kids to Lie and Cheat

Adult Dishonesty May Lead Kids to Lie and Cheat A provocative new study attacks a topic many adults would like to avoid — Do children who’ve been lied to lie more themselves?

University of California, San Diego researchers say the results of their study suggest that adult dishonesty does influence children — in the wrong way.

“This is the first experiment confirming what we might have suspected: Lying by an adult affects a child’s honesty,” said Dr. Leslie Carver, an associate professor of psychology and human development

Study findings are reported in the journal Developmental Science.

The study tested 186 children ages three to seven in a temptation-resistance paradigm. Approximately half of the children were lied to by an experimenter, who said there was “a huge bowl of candy in the next room” but quickly confessed this was just a ruse to get the child to come play a game.

The others were simply invited to play, with no mention of candy.

Children were asked to identify well-known character toys they couldn’t see by their associated sounds.

The game asked children to identify character toys they couldn’t see by their sounds. Sounds and toys were pretty easy to pair: a “Tickle me” audio clip for Elmo; “I love cookies” for Cookie Monster; and “There is a rumbly in my tummy” for Winnie the Pooh.

One sound was a deliberately tricky exception: Beethoven’s “Fur Elise,” which is not associated with any commercially available character toy.

When the classical music cue was played, the experimenter was called out of the room to, supposedly, take a phone call — leaving the children alone in the room for 90 seconds and tempting them to take a peek at the mysterious toy making that sound.

The children were explicitly asked not to peek. On returning, the experimenter also explicitly asked the children to tell the truth. Cameras rolled the whole time.

And? The five, six and seven year-olds who had been lied to were both more likely to cheat and then more likely to lie about having done so, too.

About 60 percent of the school-aged children who had not been lied to by the experimenter peeked at the tricky temptation toy — and about 60 percent of the peekers lied about it later.

Among those that had been lied to, those figures rose to nearly 80 percent peeking and nearly 90 percent of the peekers lying.

“Why?” remains an open research question, the researchers note in their paper.

It could be the five to seven year-old children were simply imitating the behavior modeled by the adult, or it could be they were making judgments about the importance of honesty to this adult.

Or, it could be more nuanced: “Perhaps the children did not feel the need to uphold their commitment to tell the truth to someone who they perceived as a liar.”

But it didn’t seem to make any difference to the younger set, the preschoolers, whether they had been deceived by the experimenter earlier.

They peeked and lied at about the same rates. That may be because three and four year-olds don’t have very sophisticated theory-of-mind abilities yet.

“The study was not designed to get at the reasons that children are more likely to lie when they have been lied to, but to demonstrate that the phenomenon can occur,” Carver said.

What happens when trusted caregivers do the lying also remains an open research question. But Carver and Chelsea Hays are still urging restraint. Even if it’s expedient for an adult to lie — to get cooperation through deception, for example, or to get children to control their emotions — it’s probably a bad idea in the long run.

Earlier research, Carver and Hays note in the paper, has documented that the majority of parents admit to lying to their children even as they maintain that honesty is an important value.

“The actions of parents,” Carver and Hays write, “suggest that they do not believe that the lies they tell their children will impact the child’s own honesty. The current study casts doubt on that belief.”

“The study has implications not only for parenting but also for teaching scenarios and for forensic situations,” said Carver. “All sorts of grown-ups may have to re-examine what they say to kids. Even a ‘little white lie’ might have consequences.”
