Critical thinking — a system with three distinct parts.

Why critical thinking?

In the age of AI, as routine cognitive tasks are increasingly handled by machines, critical thinking is emerging as the single most important human capability in the workplace — a view shared by business leaders and AI experts alike.

What critical thinking actually is

We think whenever we need to reach a conclusion — about what to do or what to believe. We want that conclusion to be well supported by good reasons, arrived at through a deliberate process, not intuition or snap judgement. Critical thinking is the process of making clear, reasoned judgements: clarity and precision in language and thought, sound logical reasoning, and a structured approach to the problem at hand.

It requires three distinct capabilities. Remove any one of them and the thinking fails.

Each capability addresses a different facet of an issue . All three are needed.

Capability 1 · Logical reasoning

The quality of our inferences, arguments, and communications

Logical reasoning is how we judge whether a conclusion actually follows from the reasons given for it. It takes four distinct forms — each with its own structure and its own ways of going wrong. It also means weighing the credibility of claims, sources, and evidence, and structuring proposals, reports, and presentations so the reasoning is logical and hard to dismiss.

Capability 2 · Structured problem-solving & decision-making

Ensuring no dimension is left unexamined

Every problem carries dimensions that exist whether or not we examine them — the assumptions behind a course of action, its implications, the people affected, and what could go wrong in execution. McKinsey's framework, Design Thinking, and the US Army's Problem-Solving Process and MDMP are all proven — but each leaves gaps, and what is left unexamined is where the risk sits. A complete, generic framework makes every dimension explicit, systematically.

Capability 3 · Awareness of the barriers

The dimension most frameworks miss

Why all three?

Logical reasoning tells us our inferences hold — without it, we cannot trust our solutions or decisions. A structured framework ensures we examine every dimension — without it, we reason well about the parts we happen to look at and miss the ones we never thought to. Awareness of the barriers keeps biases, fallacies, and rhetoric from derailing both — because they operate regardless of how good the rest of our thinking is.

Each capability addresses a different failure mode. All three are needed.
