Let’s take a step back and have a look at some interesting facts about the word “critical thinking”. Source

1. Etymological Roots: The term “critical thinking” combines “critical,” from the Greek “kritikos,” meaning “able to discern,” and “thinking,” which pertains to the process of considering or reasoning about something. This combination underscores the concept’s foundation in discernment and analysis.
2. Historical Development: Although the concept of critical thinking can be traced back to Socrates’ method of questioning over 2,500 years ago, the formal term “critical thinking” gained prominence in educational and philosophical discourse in the 20th century.
3. Socratic Method: Socrates is often considered the father of critical thinking due to his development of the Socratic Method, which involves asking systematic questions to challenge assumptions and stimulate critical thinking.
4. Bloom’s Taxonomy: In 1956, Benjamin Bloom and others developed Bloom’s Taxonomy, a framework for categorizing educational goals that places critical thinking at the highest level, emphasizing its importance in learning.
5. John Dewey: American philosopher and educator John Dewey is another pivotal figure in the development of the concept of critical thinking, advocating for it as an essential component of education and democracy in the early 20th century.
6. Cognitive Psychology: Research in cognitive psychology has significantly influenced the understanding of critical thinking, revealing it as a complex process that involves various cognitive skills, including analysis, evaluation, and inference.
7. Critical Thinking Tests: There are standardized tests specifically designed to assess critical thinking abilities, such as the Watson-Glaser Critical Thinking Appraisal and the Cornell Critical Thinking Tests, underscoring its measurable nature.
8. Global Education: Educational systems worldwide have increasingly recognized the importance of critical thinking, incorporating it into curricula and standards to prepare students for the challenges of the modern world.
9. Interdisciplinary Relevance: Critical thinking is valued across disciplines, from the sciences and humanities to business and law, demonstrating its universal applicability in problem-solving and decision-making.
10. Technology and Critical Thinking: The rise of digital media has both challenged and facilitated critical thinking, with the vast availability of information necessitating enhanced skills in analysis and evaluation to discern truth from misinformation.

What is Critical Thinking?

Critical thinking involves questioning, analyzing, interpreting, evaluating, and making judgments about information. It stems from the Greek word “kritikos,” meaning “able to judge or discern.” Good critical thinking makes reliable judgments based on reliable information. Source

Critical thinking is not inherently negative but involves clarifying thoughts to break down problems, interpret information, and make informed decisions. It requires practice and is not innate. To improve critical thinking, one must learn to:

1. Clarify thinking purpose and context.
2. Question sources of information.
3. Identify arguments.
4. Analyze sources and arguments.
5. Evaluate others' arguments.
6. Create or synthesize one's own arguments.

Critical Thinking Skills and Mindsets

Questioning Skills

• Question the relevance and reliability of information.
• Be inquisitive and curious.
• Seek truth rather than accepting information without questioning.

Analytical Skills

• Examine ideas and information carefully.
• Consider all aspects of a problem systematically.
• Make connections between ideas.

Evaluation Skills

• Recognize and avoid flaws in reasoning.
• Compare different viewpoints and arguments.
• Consider implications of information.

Synthesis Skills

• Use logic and reason to formulate conclusions and arguments.
• Support conclusions with strong evidence from analysis and evaluation.
• Consider the bigger picture and context.

The Process of Thinking Critically

Despite the diversity of examples, a common pattern in critical thinking can be recognized, analyzed by Dewey as consisting of five phases:

1. Suggestions: Leaping forward to a possible solution.
2. Problem Formulation: Intellectualizing the difficulty into a problem.
3. Hypothesis: Using suggestions as hypotheses to guide observation.
4. Reasoning: Elaborating the hypothesis through reasoning.
5. Testing: Testing the hypothesis through action or imagination.

Components of the Process

The critical thinking process is complex and involves several steps, including:

1. Noticing a difficulty.
2. Defining the problem.
3. Formulating hypotheses.
4. Gathering evidence.
5. Testing hypotheses.
6. Reaching a conclusion.
