Our decisions are influenced by both emotional and rational thinking. Emotions play an important role in decision-making by quickly alerting us to important situations and driving moral behavior. However, rational thinking is also necessary for making good decisions, especially when faced with unfamiliar situations or complex problems with many variables. The interplay between these two systems in the brain helps us navigate decision-making, though an overreliance on either emotion or reason can lead to poor choices. Metacognition, or thinking about our own thinking, is another important tool that allows for learning from mistakes and exerting self-control over impulses.
