Skepticism is an attitude of questioning and doubt rather than automatically accepting what you hear or read. A person with skepticism doesn't immediately believe every claim they encounter. Instead, they ask for evidence and think carefully about whether something makes sense.

Imagine a friend tells you they can run a mile in three minutes. A skeptical response would be to think, “That sounds unlikely, since the world record is under four minutes,” and to ask your friend to prove it. Skepticism means being willing to say, “Show me” or “How do you know that's true?”

Skepticism is especially valuable when evaluating advertisements, rumors, or sensational stories. When a commercial promises a product will solve all your problems, a skeptical viewer questions whether those claims are realistic. When someone shares an outrageous rumor, a skeptical listener wonders if the story might be exaggerated or completely false.

Being skeptical doesn't mean refusing to believe anything or assuming everyone is lying. It means using your judgment and requiring good reasons before accepting claims as facts. Scientists practice skepticism by testing ideas through experiments rather than accepting theories without proof. A healthy dose of skepticism helps you avoid being fooled while still remaining open to learning new things when the evidence supports them.
