Three Logical Fallacies and Their Role in Critical Thinking
This paper examines three logical fallacies and their importance to critical thinking and sound decision making. Drawing on Halpern (1996) and Blair et al. (1996), the paper analyzes the tu quoque (two wrongs make a right), appeal to force (argumentum ad baculum), and straw man fallacies. Each fallacy is defined, illustrated with real-world examples from politics and business, and evaluated against the criteria of relevance, sufficiency, and acceptability that distinguish sound arguments. The paper concludes that all three fallacies violate the criterion of relevance and that recognizing them is essential for objective, rigorous reasoning in organizational and public life.

What makes this paper effective
- Each fallacy is introduced with a precise Latin name and formal definition before being grounded in accessible, real-world examples from politics and business, making abstract concepts concrete.
- The paper maintains a consistent analytical framework throughout — evaluating each fallacy against the criteria of relevance, sufficiency, and acceptability — which gives the argument internal coherence.
- Transitions between sections explicitly connect the fallacies to one another (e.g., noting that appeal to force shares irrelevance with the tu quoque), demonstrating comparative reasoning rather than isolated description.
Key academic technique demonstrated
The paper demonstrates definition-then-application reasoning: each fallacy is formally defined using cited scholarly sources, then illustrated with a specific real-world case (the Arthur Anderson scandal, the Cuban Missile Crisis, the Sun vs. Red Hat debate). This technique anchors theoretical claims in observable evidence, a core move in applied critical-thinking writing.
Structure breakdown
The paper opens with a framing introduction that identifies the purpose and previews the three fallacies. Three body sections follow in parallel structure — definition, example, significance — making the argument easy to follow. A brief summary section synthesizes the shared characteristic (violation of relevance) and reinforces the practical importance of fallacy recognition. The consistent parallel organization across body sections is the paper's primary structural strength.
Introduction
Effective decision making is contingent on an individual's ability to examine the soundness of arguments. It is important for decision makers in all walks of life and at all levels to be able to identify logical fallacies. As Toulmin, Rieke, and Janik (1979) point out, the ability to recognize fallacies is a "kind of sensitivity training" because it trains a decision maker to be sensitive to common tricks of persuasion (Halpern, 1996, p. 193). This paper explores the significance of three such common tricks of persuasion to critical thinking and decision making. The three logical fallacies examined are: two wrongs make a right, appeal to force, and straw man.
