The Origins of Happiness
Finally, we come to crime. From the British Cohort Study
we can estimate that a crime committed under the age of
34 reduces the criminal’s happiness by 0.30 point- years.^10
But, using data from the British Crime Survey, it reduces the
happiness of the rest of the population about 1 point- year.
How the Child Predicts the Adult
The information so far tells us what we could achieve by
directly influencing the situation of an adult. But another
way to influence adults is through altering their childhood.
In Table 16.3 we examine the three main dimensions of
child development and ask how well they predict the result-
ing adult. Column (1) shows the effects on life- satisfaction.
The best predictor of how far adults are satisfied with their
lives is not their academic performance but their emotional
health in childhood. Neither their academic performance
nor their behavior— the central focuses for educators— is as
important for them as their emotional health.
