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 relying too heavily on either can lead to errors. Metacognition, or thinking about our own thinking, also influences the decisions we make.
