Critical thinking lesson 1: What is critical thinking? · Set 823 · 40 questions

Thinking tip (How do you know?): A critical thinker asks “How do you know?”, checks the facts first, listens to both sides, looks for reasons and thinks before deciding. Not critical thinking: believing every rumour, deciding in a hurry, hearing only one side, copying what everyone does, sharing without checking. A new fact can change the answer — a good thinker changes their mind with proof.
