Course Overview

What this course is designed to develop

This course grounds you in evidence-based reasoning, classical and informal logic, and structured decision-making frameworks used by analysts, scientists, and strategists. You will practice identifying cognitive biases, testing arguments for validity and soundness, and applying tools like the Socratic method and the Toulmin model to real professional scenarios. By the end you will have a repeatable process for separating signal from noise and arriving at well-justified conclusions.

Learning Outcomes

What the learner should be able to understand, build, or execute.

Identify and name at least 15 common logical fallacies and cognitive biases in written and spoken arguments

Apply the Toulmin argumentation model to deconstruct and rebuild claims with supporting evidence

Use the PEEL and Socratic questioning frameworks to stress-test assumptions in workplace decisions

Evaluate the quality of evidence using source credibility criteria, sample size checks, and base-rate reasoning

Distinguish valid from sound arguments and correlation from causation using concrete worked examples

Construct a structured argument brief that withstands adversarial scrutiny from peers
