Thinking for yourself instead of accepting claims at face value — withholding snap judgements, weighing alternatives and asking "why?" — so that you handle and pass on knowledge responsibly.

Critical thinking is not being negative or sceptical of everything. It is a disciplined habit of reasoning made of a few moves:

• Think independently — form your own judgement rather than adopting one ready-made.
• Avoid judging too quickly — resist the first plausible conclusion; let evidence catch up.
• Accept that different ideas exist — take opposing views seriously enough to evaluate them.
• Keep asking "why?" — push past the surface claim to its reasons.
• Look for alternatives — assume there may be another explanation or solution you haven't seen.

The point of all this is practical, not academic: a responsible relationship with opinions, with the knowledge you pass on to others, and ultimately with how you act. Sloppy thinking spreads — so thinking well is partly an ethical duty, not just a skill.

Tip: A useful one-line test — "Could I explain why I believe this to someone who disagrees?" If not, you've recognised a claim, not thought critically about it.
