“Lying is also apparently a coming-of-age marker of sorts for kids. “Children’s lies are a sign that they have reached an important milestone in their life,”
says Kang Lee, professor and director of the Institute of Child Study at the University of Toronto to the Toronto Star.
“Children’s lies and their sophistications of lies only reflect better cognitive development in terms of executive functioning — the ability to pay attention, to plan, to control impulses and to switch readily between tasks — and their ability to read another person’s mind.”
