Think with AI. Keep the judgment human.
Critical Thinking, Decision-Making & AI Literacy
A PRACTICAL JUDGMENT FRAMEWORK
Decide what deserves belief—and what should follow.
Separate claims from conclusions, investigate sources, evaluate evidence, test alternatives and make uncertainty visible before acting. AI can help explore this process; it cannot own the result.
QUESTION → VERIFY → ANALYZE → CHALLENGE → DECIDE → REVIEW.
01 / Understand
What does good judgment require?
Follow the claim through its source, evidence, assumptions, alternatives and uncertainty before deciding what it supports.

Facts, Opinions, Assumptions & Inferences
Separate observations and verifiable facts from opinions, assumptions, inferences and interpretations before acting on a conclusion.

What problem are we actually trying to solve?
Follow the claim through its source, evidence, assumptions, alternatives and uncertainty before deciding what it supports.
Existing OpenSkool field note
Better work begins with better questions
Separate the request from the problem, make assumptions visible and finish with an answerable next question.

What evidence supports the claim, and how good is the source?
Follow the claim through its source, evidence, assumptions, alternatives and uncertainty before deciding what it supports.

The Most Confident Answer Is Not Always the Best Answer
