Research Summaries: Self-Discipline Outdoes IQ in Predicting Academic Performance of Adolescents
Today’s research summary focuses on a very early article by Angela Duckworth, that first catapulted her to fame. Co-authored with Martin Seligmen, the article focuses on how non-cognitive factors like self-control are a better predictor of scholastic achievement than say cognitive factors like IQ.
- Authors use the awkward term self-discipline in the paper, but all they really meant was self-control, defining which, and around which, a rich literature already existed. Angela clarifies as much in her new MOOC on Coursera, so don’t start wondering what this new concept means in psychological literature.
- Self-control (which the authors surprisingly didn’t define), as per VIA, is the ability to be disciplined and to regulate what one feels and does; it involves both feelings and actions; it is the ability to delay present gratification for future benefits, and it also about not getting distracted by temptations and able to focus on the task at hand. It is the opposite of being impulsive.
- The present studies (two of them) focused on class VIII students and were partly driven by Angela’s observation as a math teacher that hard working students who could control their impulses, sometimes fared better than those who could grasp concepts easily. That drove part of the hypothesis.
- Earlier works has shown that Self-control, as measured by Marshmallow test, in 4 year olds, can predict positive life outcomes decades later; similarly, in college students out of 32 measured personality traits (like extraversion, energy levels etc), only self-control predicted later CGPA more robustly than earlier SAT scores. Thus, it was reasonable to hypothesize that self-control in eighth graders will predict academic achievement better than IQ.
- Self-control is a difficult thing to measure accurately. Thus, they used self-reports, teacher reports, parent reports as well as a test that gave students hypothetical choices between a small reward now or a big reward later. Angela actually wanted to do an age appropriate test similar to marshmallow test with the eighth graders, but Marty was skeptical; in the second study they did include a behavioral measure of delay of gratification task, whereby they actually handed out 1$ envelope to students with a choice of keeping that or returning it now to get 2$ next week.
- Academic achievement was measured by grades achieved at end term, attendance, selection into a high school program, and achievement test scores.
- IQ was measured using a standard IQ test; keep in mind that IQ is a very narrow assessment for a part of broader cognitive factors/ intelligence.
- What they found was that self-control not only predicted academic achievement and who would improve school grades over the class term, but that it was twice an effective predictor than IQ (explained twice as much variance).
- This is an important paper as it makes the case for enhancing and working on the self-control of students, for better academic performance. Self-control, by all means, and like any other character strength, is malleable and can be increased by proper interventions.
- This paper is personally relevant to me, as last year I worked with IXth class students on their character strengths and this year I am working with VIII class students focusing on their character strengths. Although the results, I believe, will be applicable and generalize to other age groups, its heartening to note that at least for VIII class, barring cross-cultural effects, there is proven research showing that increasing strengths like self-control pays big dividends.
