Mathematics and Decisions

Introduction. While there is broad consensus that mathematics is important across all education levels, decision-making is often treated as secondary in most curricula. Objective. This paper explores the relationship between mathematical ability and decision-making. Topics for Reflection. It suggests three models: one where mathematical ability influences decisions, another where decision-making influences mathematical ability, and a third proposing mutual influence. The authors review existing research supporting the first two models, highlighting the role of numeracy and decision parameters. Finally, they argue for the likelihood of a mutual influence model, emphasizing the importance of considering both mathematical skills and decision-making processes in understanding mathematical achievement. Conclusions. The mutual influence model has consequences for the future of mathematical education because it would require explicit training in decision making abilities at some point in school. Students need to be aware of such influence.
