Critical Thinkers • Distinguish between fact and opinion • Ask questions; make detailed observations; uncover assumptions and define their terms; and • Make assertions based on sound logic and solid evidence. Ellis, D. Becoming an Master Student, 1997)
Questions to ask • What do you mean by …? • How did you come to that conclusions? • What is the source of your information? • What assumptions led you to that conclusion? • What are the implications if you are wrong? • Why did you make that inference? Is another one more consistent with the data? • Why is this issue significant? • What is an alternate explanation for this phenomenon?
Barriers to Critical Thinking Lack of relevant background information Poor reading skills Biases Prejudice Superstition Peer Pressure Resistance to change Rationalization Stereotyping Wishful thinking Unwarranted assumptions
