Long-term v Short-term Follow-up: The Stanford Marshmallow Experiment

From Wikipedia:

The Stanford marshmallow experiment was a study on delayed gratification in 1972 led by psychologist Walter Mischel, a professor at Stanford University. In this study, a child was offered a choice between one small but immediate reward, or two small rewards if they waited for a period of time. During this time, the researcher left the room for about 15 minutes and then returned. The reward was either a marshmallow or pretzel stick, depending on the child’s preference. In follow-up studies, the researchers found that children who were able to wait longer for the preferred rewards tended to have better life outcomes, as measured by SAT scores, educational attainment, body mass index (BMI), and other life measures. A replication attempt with a sample from a more diverse population, over 10 times larger than the original study, showed only half the effect of the original study. The replication suggested that economic background, rather than willpower, explained the other half.

This experiment confirmed through empirical evidence what theorists like Bancroft had argued: people who lived in the moment and could not delay gratification had worse life outcomes. What’s interesting from the above is that poor health is mentioned.

The Stanford study really got the ball rolling on delayed gratification and self-control. A more recent one followed 1000 children from birth to age 32 and concluded that “childhood self-control predicts physical health, substance dependence, personal finances, and criminal offending outcomes.”

Is it any surprise then that many people who developed diabetes through poor lifestyle choices continue with those poor choices and get worse. It is not when we consider living in the moment versus thinking about the future.

Again, I choose self-control and delayed gratification.
