Critical thinking questions assumptions that are not based on facts, credible observations or research. It is a way of deciding whether a claim is always true, sometimes true, partly true, or false. Critical thinking includes a complex combination of skills. Among the main characteristics…


We are thinking critically when we

  • rely on reason rather than emotion,
  • require evidence, ignore no known evidence, and follow evidence where it leads, and
  • are concerned more with finding the best explanation than being right analyzing apparent confusion and asking questions.


We are thinking critically when we

  • weigh the influences of motives and bias, and
  • recognize our own assumptions, prejudices, biases, or point of view.


We are thinking critically when we recognize emotional impulses, selfish motives, nefarious purposes, or other modes of self-deception.


We are thinking critically when we

  • evaluate all reasonable inferences
  • consider a variety of possible viewpoints or perspectives,
  • remain open to alternative interpretations
  • accept a new explanation, model, or paradigm because it explains the evidence better, is simpler, or has fewer inconsistencies or covers more data
  • accept new priorities in response to a reevaluation of the evidence or reassessment of our real interests, and
  • do not reject unpopular views out of hand.


We are thinking critically when we

  • are precise, meticulous, comprehensive, and exhaustive
  • resist manipulation and irrational appeals, and
  • avoid snap judgments.


We are thinking critically when we

  • recognize the relevance and/or merit of alternative assumptions and perspectives
  • recognize the extent and weight of evidence


  • Critical thinkers are by nature skeptical. They approach texts with the same skepticism and suspicion as they approach spoken remarks.
  • Critical thinkers are active, not passive.  They ask  questions and analyze. They consciously apply tactics and strategies to uncover meaning or assure their understanding.
  • Critical thinkers do not take an egotistical view of the world. They are open to new ideas and perspectives.  They are willing to challenge their beliefs and investigate competing evidence.

Critical thinking enables us to recognize a wide range of subjective analyses of otherwise objective data, and to evaluate how well each analysis might meet our needs. Facts may be facts, but how we interpret them may vary.

By contrast, passive, non-critical thinkers take a simplistic view of the world.

  • They see things in black and white, as either-or, rather than recognizing a variety of possible understanding.
  • They see questions as yes or no with no subtleties.
  • They fail to see linkages and complexities.
  • They fail to recognize related elements.

Non-critical thinkers take an egotistical view of the world

  • They take their facts as the only relevant ones.
  • They take their own perspective as the only sensible one.
  • They take their goal as the only valid one.
