- Interpretation
- Analysis
- Inference
- Evaluation

Key Tasks & Guiding Questions
• Interpretation – clarify meaning (“What does this mean?”)
• Analysis – uncover arguments, assumptions (“What is your conclusion?”)
• Inference – draw reasonable conclusions (“Given what we know, what follows?”)
• Evaluation – judge credibility & logical strength (“How credible is that claim?”)
• Explanation – justify reasoning (“Please walk us through your reasoning.”)
• Self-Regulation – monitor & refine thinking (“What are we missing?”)
Obstacles to Critical Thinking
- Fallacious reasoning
- Bias in data gathering, assumptions, or conclusions
Frequent Logical Fallacies
• Straw Man • Ad Hominem • Appeal to Popularity • Appeal to Tradition • Genetic Fallacy • Equivocation • Appeal to Ignorance • False Dilemma • Begging the Question • Hasty Generalization • Slippery Slope • Composition • Division
- Ask basic questions (What do we know? How?)
- Challenge assumptions; reverse causality
- Monitor mental processes: heuristics & cognitive biases
- Use: Checklists (process rigor), Mindfulness (awareness), Brainstorming (idea fluency)
Problem-Solving Guidelines
- Focus on solutions, not problems
- Apply the “5 Whys” to reach root cause
- Simplify (Occam’s Razor)
- Generate many alternatives; think laterally
- Use possibility language: “What if…?”
