What critical thinking actually means
Critical thinking isn't being negative or picking holes in everything. It's being fair to the evidence — including the evidence that you're wrong.
In everyday life it mostly comes down to one question: “How do I know that's true?”
The 6 core critical thinking skills
- Questioning — asking what a claim rests on, and who benefits from you believing it.
- Separating facts from assumptions — knowing which parts are confirmed and which are just likely.
- Weighing evidence — trusting independent, written and recent sources over confident voices.
- Spotting bias — noticing when you only want one answer to be true.
- Considering alternatives — naming at least one other explanation or option before you settle.
- Testing and reviewing — checking the key claim in a small way, then learning from what happened.
Everyday exercises to build critical thinking
- Rewrite one decision a day as “I'm assuming that…” and underline the assumption.
- Before sharing a news story, find the original source.
- When someone says “everyone's doing it”, ask for one specific example you can check.
- Run a two-minute pre-mortem: imagine the decision went wrong and write down the most likely reason.
Frequently asked questions
What are the main critical thinking skills?
Lists vary, but most include analysis (breaking a problem down), evaluation (weighing evidence), inference (drawing sound conclusions), explanation, and self-regulation (checking your own reasoning and bias).
How can I improve my critical thinking quickly?
Practise on real, low-stakes decisions. Each time, name the assumption, ask what would prove it wrong, and find one independent source before acting.
Is critical thinking the same as decision-making?
They overlap. Critical thinking judges whether information is reliable; decision-making turns that judgement into a choice and a next step.
