Strong Reasons vs Weak Reasons

🔎Case Brief #10

👫 You and your friend disagree about something.

🎯 Your mission

Master the idea.

⚡ The twist

If you change your mind, explain why.

What You'll Learn

🧠 Not all reasons are equal! Some reasons are STRONG (backed by facts and evidence) and some are WEAK (based only on feelings or guesses). Learning to tell the difference makes you an excellent thinker. Here's how to do it: 1. Look carefully at the problem. What do you see? 2. Think about what you already know. Does this remind you of something? 3. Try an answer! It's totally okay to be wrong — that's how we learn. 4. Check: did it work? If not, try something else! You're building your thinking muscles. The more you practice, the stronger they get!
