Exercises Critical Thinking

Practise deliberately with small tasks that produce observable evidence of improvement.

The idea in one minute

Critical thinking is disciplined judgment under uncertainty. It involves defining the question clearly, identifying what is known and what is merely assumed, evaluating the quality and relevance of evidence, checking for plausible alternative explanations, noticing how incentives and cognitive biases may distort interpretation, and deciding what level of confidence is justified. Strong critical thinking is not reflexive skepticism or arguing both sides forever. It is the ability to make a defensible decision while remaining willing to revise that decision when better evidence appears.

This capability connects directly with AI Literacy, Decision Making, Problem Solving. Open those concepts when the lesson depends on them rather than treating Critical Thinking as an isolated ability.

Beginner exercises

  1. 1.For one recommendation each day, write four lines: the claim, the evidence, the hidden assumption, and what would change your mind.
  2. 2.When reading a chart or headline, identify the denominator, time period, comparison group and original source before repeating the conclusion.
  3. 3.Keep a short decision journal for one week and record what you expected to happen versus what actually happened.

Applied exercises

  1. 1.Before a meaningful decision, generate at least two plausible alternative explanations and identify evidence that would distinguish between them.
  2. 2.Run a premortem on a project: assume it failed, list credible reasons why, and convert the strongest risks into checks or mitigations.
  3. 3.Review one AI-generated or stakeholder recommendation and explicitly mark facts, inferences, assumptions, uncertainties and decision costs.

Measure your progress

  1. 1.Track whether you can state the real decision question clearly, identify assumptions before they fail, distinguish correlation from causation, estimate confidence without false precision, catch unsupported claims, and update conclusions when evidence changes. In team settings, useful signals include fewer repeated reasoning errors, better decision records and clearer explanations of trade-offs and uncertainty.

AI LiteracyAI literacy is the judgment and working knowledge needed to decide when an AI system belongs in a task, give it useful context, test what it produces, and keep responsibility for the outcome with the person using it.Decision MakingDecision making is the ability to choose and commit to an action when evidence, uncertainty, values and trade-offs compete, while making the reasoning explicit enough to review and improve.Problem SolvingProblem solving is the ability to move from an unclear or undesirable situation to a tested improvement by defining the problem, diagnosing likely causes, comparing options, acting on the strongest hypothesis, and checking whether the intervention actually worked.Data AnalysisData analysis is the ability to turn a real question into trustworthy evidence by defining the right measure, checking data quality, analyzing patterns and uncertainty, and communicating what the data can—and cannot—support.Human-AI CollaborationThe ability to divide, coordinate and review work between people and AI so each contributes where it is strongest while humans retain appropriate judgment and accountability.
