Can we hope to be rational when it comes to feelings?
steps for critical thinking
The critical thinking process, as described by Wolcott and Lynch (4), includes four steps. Students generally begin their critical thinking at step one and, with practice, progress to step 2 and up the ladder.
Step 1: | Identify the problem, the relevant information, and all uncertainties about the problem. This includes awareness that there is more than one correct solution. (low cognitive complexity) |
Step 2: | Explore interpretations and connections. This includes recognize one's own bias, articulating the reasoning associated with alternative points of view, and organizing information in meaningful ways. (moderate cognitive complexity) |
Step 3: | Prioritize alternatives and communicate conclusions. This includes thorough analysis, developing the guidelines used for prioritizing factors, and defending the solution option chosen. (high cognitive complexity) |
Step 4: | Integrate, monitor, and refine strategies for re-addressing the problem. This includes acknowledging limitations of chosen solution and developing an ongoing process for generating and using new information. (highest cognitive complexity) |
If the instructor can determine where in the step process students are functioning, then guided feedback can be provided. This will help students think through those skills not being utilized. Over time the students can check themselves to see which areas are being omitted.

What is Critical Thinking?
What is Critical Thinking?
Critical thinking includes a complex combination of skills. Among the main characteristics are the following:
Rationality
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.
Self-awareness
We are thinking critically when we- weigh the influences of motives and bias, and
- recognize our own assumptions, prejudices, biases, or point of view.
Honesty
We are thinking critically when we recognize emotional impulses, selfish motives, nefarious purposes, or other modes of self-deception.Open-mindedness
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.
Discipline
We are thinking critically when we- are precise, meticulous, comprehensive, and exhaustive
- resist manipulation and irrational appeals, and
- avoid snap judgments.
Judgment
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 natureskeptical. They approach texts with the same skepticism and suspicion as they approach spoken remarks.
- Critical thinkers areactive, 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 areopento new ideas and perspectives. They are willing to challenge their beliefs and investigate competing evidence.
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.
- They taketheirfacts as the only relevant ones.
- They taketheir ownperspective as the only sensible one.
- They taketheir goalas the only valid one.
