Critical thinking is the intellectually disciplined process of actively and skillfully conceptualizing, applying, analyzing, synthesizing, and/or evaluating information gathered from, or generated by, observation, experience, reflection, reasoning, or communication, as a guide to belief and action. In its exemplary form, it is based on universal intellectual values that transcend subject matter divisions: clarity, accuracy, precision, consistency, relevance, sound evidence, good reasons, depth, breadth, and fairness.
Argument mapping is producing "boxes and arrows" diagrams of reasoning, especially complex arguments and debates. Argument mapping improves our ability to articulate, comprehend and communicate reasoning, thereby promoting critical thinking.
You can think argument mappings as visual hierarchy mappings.
Arguman.org’s aim is arguments to be mapped successfully by many users.
