Three-year-olds can be identified as criminals of the future

A fifth of the population is responsible for four fifths of crime, two fifths of obesity, three quarters of fatherless families and for claiming two thirds of benefits. What’s more, scientists say, you can identify this troublesome group at the age of three.

A 45-minute test rating children on IQ and self-control, combined with information about deprivation and maltreatment, allowed researchers to predict “with considerable accuracy” which would go on to be the greatest burden on the state. The 38-year study may be useful in designing ways to help such children before it is too late.
