Moffitt said it's still unclear why some children have better self－control than others, though other researchers have found that it's mostly a learned behaviour, with relatively little genetic influence. But good self－control can run in families because children with good self－control are more likely to grow up to be healthy and prosperous parents.

　　“Some of the low self－control study members are more likely to be single parents with a very low income and the parent is in poor health and likely to be a heavy substance abuser，” said Moffitt. “So that's not a good atmosphere for a child. So it looks as though self－control is something that in one generation can influence the next generation.”
