In recent years, there has been growing interest in the role of metacognition in decision making, thus spawning the field of metareasoning. However, the extant metareasoning literature has largely focused on reasoning tasks in which participants' metacognitive judgments can be compared to objective standards, such as accuracy or solvability. While these studies provide valuable insights into the important role that metacognition plays in objective decision making, it is unclear how these findings may generalize to the many subjective decisions – such as who to marry, which house to purchase, which college to attend, and which medical treatment to undergo – that are pervasive in decision makers’ lives and have significant impacts on their long-term happiness and well-being.  As such, this project seeks to investigate the role of metacognition in subjective decision making by exploring decision makers' metacognitive knowledge of the attributes weights they apply in subjective, multi-attribute choice decisions. This project has four central goals:

I am also interested in expanding this line of research to explore the metacognitive control strategies that decision makers use to improve their decision making processes in subjective, multi-attribute choice. Specifically, I have three additional goals:
