Many parents become alarmed when their child begins lying frequently. But does lying in childhood predict criminal behavior later in life?
Researchers from McGill University, the University of Montréal and John Jay College of Criminal Justice studied children from ages 6 to 19 to examine how lying changes over the course of development. They concluded that lying is a normal part of childhood for most children. Most either lie less frequently as they grow older or lie only occasionally.
When does lying become a warning sign?
The study found that lying itself was not associated with later criminality. Instead, researchers identified a more concerning pattern: persistent lying that increases with age and occurs alongside aggression, impulsivity and poor self-control.
A small group of children showed this pattern, either lying frequently from an early age or becoming increasingly prone to lying as they grew older. These children were also more likely to later display antisocial behavior, experience legal problems and have criminal convictions in adulthood.
Lying can be a normal part of growing up
The findings do not mean that children who occasionally lie should be considered problematic. For most children, lying is a normal part of development and tends to decrease with age.
However, persistent or increasingly frequent lying, particularly when accompanied by aggression, impulsivity or other behavioral problems, may warrant closer attention and, if necessary, professional guidance.
