Disagreeing with seniors and teachers

Disagreeing with someone senior feels risky, especially where respect for elders and teachers runs deep. Make it easier by choosing the setting: a private conversation is often better than correcting them in front of others. Ask questions rather than declaring they are wrong: "Could you help me understand why we chose X over Y?

I was worried about..." Bring evidence: a link, a number, a test. Accept that the final decision may be theirs.

You have done your job by raising the point clearly. If something is unsafe, unethical or illegal, that is different; raise it firmly and use official channels if needed.
