Critical Thinking Depth
Critical Thinking Depth is built around the five-skill structure of the Watson-Glaser Critical Thinking Appraisal (Watson & Glaser, 1925 onward; still one of the most widely used critical-thinking measures in professional and legal hiring): Inference, Recognition of Assumptions, Deduction, Interpretation, and Evaluation of Arguments. Each section isolates one skill so the results show exactly where your reasoning is strong versus where it slips.
Your answers save as you go, so you can stop and resume.

Inference
Judging the truth-value of conclusions from stated facts alone.
Recognition of Assumptions

Deduction
Judging formal validity independent of real-world plausibility.
Interpretation
