Spotting assumptions and jumping to conclusions — Critical thinking for kids

An assumption is an idea we take as true without checking. “The shop is closed, so today must be Sunday” assumes the shop closes only on Sundays. Jumping to conclusions means treating a guess as a fact: “Diya didn’t wave back, so she must be angry.” Maybe she just didn’t see you. Careful thinkers say “maybe”, look for more clues and ask.

Thinking tip

Maybe — let me check — “think of other reasons before you decide”

  1. Jumping to conclusions: “The new boy is quiet, so he must be rude.”, “He got full marks, so he must have copied.”
  2. Checking first: “The new boy is quiet. I’ll talk to him and find out more.”, “The shop is dark. Let me read the notice on the door.”
  3. Careful habits: asking before judging, looking for more clues, thinking of other causes. Hasty habits: guessing the worst, judging by looks.

Use it for: Friendships, new classmates, unanswered messages, school news and judging people.

Worked example: 🕵️ Jumping to conclusions, or checking first? “He got full marks, so he must have copied.” → jumping to conclusions

  1. Full marks can come from hard work; there is no proof of copying.
  2. Treating that guess as fact is jumping to conclusions.

Check: Try it: the next time you think “they must be…”, write two other possible reasons first ✓
