Essential techniques for rigorous analysis
Turn critical thinking from theory into practice: dismantle arguments, question deeply, think like a scientist, and decide well under uncertainty.
Overview
What this module covers
Core Skills covers the four practical techniques that carry most of the load: breaking an argument into its parts, using Socratic questioning to examine a belief, applying the scientific method to everyday questions, and running a structured decision process instead of reacting to whichever option feels right.
Core Skills is where the vocabulary from Foundations becomes something you can actually do. Each of the four lessons is a repeatable procedure that the sharpest thinkers run daily: dismantling an argument, questioning your way toward the truth, testing an idea like a scientist, and choosing well when the future refuses to hold still.
You will pick up a five-step check for any argument, the varieties of Socratic question and when each one earns its place, how to run the scientific method on your own life, and a decision process that scales your effort to the stakes. These are moves rather than facts. The aim is to rehearse them until they fire automatically.
The real payoff comes from doing, not reading. Between lessons, work the matching practice on the Exercises page, starting with Advanced Arguments. Each procedure then hardens into a reflex you reach for without thinking.
Outcomes
Learning objectives
- Dismantle any argument using a repeatable five-step check
