Little liars grow up to be great leaders
Lying involves multiple brain processes, such as integrating sources of information and manipulating the data to their advantage. It is linked to the development of brain regions that allow executive functioning and use higher order thinking and reasoning.
Dr Lee and his team tested 1,200 children aged two to 16 years old. They found at the age of two, 20 per cent of children will lie. This rises to 50 per cent by three and almost 90 per cent at four. The most deceitful age, they discovered, was 12, when almost every child tells lies.
Researchers say there is no link between telling fibs in childhood and any tendency to cheat in exams or to become a fraudster later in life.
