Have you ever wondered why some people draw energy from crowds while others recharge in solitude? In 1921, Carl Jung revolutionized our understanding of human psychology with his groundbreaking work on psychological types. Before Jung, personality was often viewed through a pathological lens-you were either normal or abnormal. Jung's genius was recognizing that different psychological orientations represent equally valid ways of experiencing reality, not deficiencies or disorders. His insights gave us the language we now use daily-introvert, extravert, thinking, feeling-and created a framework for understanding human differences that transcends culture and time. At the core of Jung's theory lies a fundamental split in how psychic energy flows. For extraverts, this energy moves outward toward people and objects in the external world. They're energized by social interaction and oriented toward objective reality. For introverts, energy flows inward toward concepts, ideas, and subjective experience. They find stimulation in their rich inner landscape and often need solitude to recharge. This isn't simply about being "social" versus "shy"-it's about where you naturally direct your attention and draw your energy. As Jung observed, these orientations manifest across history in everything from philosophical debates to religious schisms to artistic movements.
