(Medical Xpress) -- “That’s not fair!” It’s a common playground complaint. But how early do children acquire this sense of fairness? Before they’re 2, says a new study.

At a playground, it’s not uncommon to hear the refrain, “That’s not fair!” It seems that young children worry a lot about fairness, but psychological scientists have typically assumed that kids don’t start to understand morality until they reach their preschool years. New research, however, on 19- to 21-month-olds has indicated that sensitivity to fairness might begin a lot earlier.
