Self-control matters - but to what extent can it be taught?

Recently in the news, a report published by the independent think-tank Demos reminds us of the importance of the capacity for self-control (it also mentions empathy, to which most of the following remarks apply) in determining life outcomes. It argues that self-control lessons should be taught at school if children, particularly from deprived backgrounds, are to be given the tools they need to succeed in life – low-self-control has for instance been shown to positively correlate with length of unemployment or criminal behaviour, and negatively with academic achievement. The report echoes renewed interest in the United States in a now famous experiment by Walter Mischel on deferred gratification, dating back to the late 1960s. Mischel tested the capacity of a group of four-year olds to resist the temptation to eat straightaway a marshmallow he had given them. The children who were able to refrain turned out to be better adjusted, more dependable and to do better academically on the whole later in life.

 

The report by Demos makes important points and its proposals deserve to be supported. Nevertheless, even if they are put into practice, we might still feel concerned about how effective we can expect them to be. There is indeed a body of evidence suggesting that the capacity for self-control is to a large extent genetically determined (Wright & Beaver, 2005; Beaver & al., 2009).
