Critical Thinking

Critical thinking is the disciplined habit of questioning claims, examining evidence, clarifying goals, and testing whether conclusions actually follow from reasons.

Core Idea

It is not blanket negativity and it is not clever contrarianism. It is constructive skepticism applied to real decisions.

Useful operations include:

defining the actual question
gathering relevant evidence
testing assumptions
considering implications
exploring competing viewpoints
checking for contradiction and fallacy

A deeper layer is understanding the direction of the reasoning itself. Inductive reasoning builds general claims from specific observations and produces conclusions that are probable but never certain. Deductive reasoning applies established rules or premises to specific cases and produces conclusions that must follow if the premises are true. Critical thinking requires recognizing which direction is being used, because each carries different standards for what counts as strong reasoning.
