Critical Thinking
Core Definition
Critical thinking is the disciplined process of actively and skillfully conceptualizing, applying, analyzing, synthesizing, and evaluating information gathered from observation, experience, reflection, reasoning, or communication to guide belief and action. It involves the ability to think clearly and rationally, understanding logical connections between ideas, identifying and challenging assumptions, and evaluating evidence objectively.
Critical thinking transcends simple analysis to encompass intellectual virtues such as intellectual humility, curiosity, integrity, and courage. In the digital age, critical thinking has become essential for navigating information abundance, detecting manipulation, and making informed decisions in complex, rapidly changing environments.
