Every day, people make thousands of decisions — some as simple as choosing what to eat, others as significant as changing careers, investing money, or making life-altering personal choices. While many assume these decisions are the result of careful reasoning, modern neuroscience suggests the human brain often relies on shortcuts, emotions, and unconscious biases. Over the past two decades, however, scientists have made remarkable progress in understanding how people can make better choices by studying an emerging concept known as metacognition.
Although philosophers have discussed self-awareness for centuries, metacognition only began attracting significant attention from neuroscientists in the late 2000s. Since then, researchers have uncovered fascinating insights into how the brain reflects on its own thinking—and why this ability may be one of humanity's greatest cognitive strengths.
