In contrast, individuals with Fixed Mindsets believe that their skills are at least partially pre-determined, and thus can only be improved so much before they reach their personal limit. Over the last three decades, researchers have demonstrated that individuals with Growth Mindsets outperform individuals with Fixed Mindsets in numerous domains. However, relatively little research has been conducted to explore the boundary conditions of the superiority of Growth Mindsets over Fixed Mindsets. One potential downside of Growth Mindset is that its emphasis on persistence could lead individuals to overpersist on tasks for which opportunity costs for time are high and giving up on a task (so that more time can be dedicated to a different task) could be an optimal strategy. To explore this possible "cost" of having a Growth Mindset, we are seeking to answer the following questions:
