Some highlights
Lying is, in truth, a milestone of normal child development and starts as early as age 2. More than one-third of 3-year-olds will lie to keep from getting in trouble, based on research led by Victoria Talwar, an associate professor of developmental psychology at McGill University in Montreal. By ages 4 to 7, more than half of children will lie to avoid punishment
Parents are remarkably bad at detecting their children's lies. In experimental studies of preschoolers, parents were able to detect accurately when their children were lying only 53% of the time—a little better than chance, according to a 2010 study led by Dr. Talwar. That falls to 33% by the time their kids are 6 to 8 years old. And parents of 9- to 11-year-olds have only about a 1 in 4 chance of knowing when their kids are lying.
Moms and dads have what researchers call "a truthfulness bias." They want and need to believe their kids are telling the truth.
The lesson, Ms. Gorski says: It's important "to be an honest person, but there are many ways to communicate the truth without being blunt or forceful or harsh."
