A well cultivated critical thinker:
- raises vital questions and problems, formulating them clearly and precisely;
- gathers and assesses relevant information, using abstract ideas to interpret it effectively comes to well-reasoned conclusions and solutions, testing them against relevant criteria and standards;
- thinks openmindedly within alternative systems of thought, recognizing and assessing, as need be, their assumptions, ideologies, implications, and practical consequences; and
- communicates effectively with others in figuring out solutions to complex problems.
Critical thinking is, in short, self-directed, self-disciplined, self-monitored, and self-corrective thinking. It presupposes assent to rigorous standards of excellence and mindful command of their use. It entails effective communication and problem solving abilities and a commitment to overcome our native egocentrism and sociocentrism. — Adapted from Richard Paul and Linda Elder, The Miniature Guide to Critical Thinking Concepts and Tools, Foundation for Critical Thinking Press, 2008
