Unit 1 · TLU-PWR-113Self-guided lessonPWR-113 · Deductive reasoning
This exercise asks one narrow question: if all stated premises were true, would the conclusion have to be true? The eight arguments use invented categories so real-world beliefs do not decide the answer. For an invalid argument, supply one possible case where every premise is true and the conclusion false. For a valid argument, state the short chain that makes a counterexample impossible. Plausibility, confidence and factual truth are not substitutes for validity. The cards are untimed and may be represented in plain language, symbols, audio or diagrams. Do not transfer the score to intelligence, general rationality or consequential legal, clinical, financial, employment or security judgments; those require domain expertise and accountable review. Stop if the drill becomes an intelligence comparison, high-pressure timed test or tool for a real dispute.

Unit 2 · TLU-PWR-114Self-guided lessonPWR-114 · Inductive inference
Inductive inference means proposing more than one rule from limited examples, predicting new cases before seeing their memberships and revising without erasing the original prediction. This pack begins with three fictional cards. The learner generates two candidate rules, predicts all three hidden test memberships and locks confidence before opening one staged key. The goal is a better-supported rule with visible uncertainty, not certainty from a tiny pattern set.

Unit 3 · TLU-PWR-115Self-guided lessonPWR-115 · Probabilistic reasoning
This tutorial teaches the full forecast-record cycle on ten benign fictional events. Define the event and reference class, convert favourable cases to a natural frequency, lock a probability, reveal the staged outcome, calculate the Brier score, preserve every row, inspect the direction of the largest errors and write one method update for a fresh set. The exercise is not financial, medical or safety-critical forecasting.

Unit 4 · TLU-PWR-116Self-guided lessonPWR-116 · Causal reasoning
Causal reasoning asks more than whether two variables move together. This pack supplies four fictional cases spanning observation, self-selection, and randomised intervention. The learner names cause and outcome, checks design and time order, generates alternatives, proposes discriminating evidence, and writes a bounded classification. Numerical differences remain descriptive until design supports a causal interpretation.

Unit 5 · TLU-PWR-117Full low-stakes tutorialPWR-117 · Systems thinking
The learner produces a legible system map with a declared boundary, one stock, two flows, one feedback loop, one delay, evidence labels and a falsification check.

Unit 6 · TLU-PWR-118Full supervised tutorialPWR-118 · Expert judgement
Under a qualified provider, the learner completes at least 20 resolved domain cases and produces a Brier score (mean squared probability error), calibration bands, discrimination and an error review for the declared case mix.
Tutorial mode: supervised
Capability self-practice: Qualified supervision is required for the practical method

The learner produces a traceable fictional decision record with options, probability ranges, consequences, protected constraints, sensitivity analysis, threshold and update rule.

Unit 8 · TLU-PWR-120Full low-stakes tutorialPWR-120 · Strategic planning
The learner creates a fictional strategy with a measurable outcome, backward milestones, dependencies, assumptions, one disruption rehearsal, review triggers and a retirement rule.
