“Use your common sense”: how to say it politely
Why it can fall flat
“use your common sense”
Most people hear “use your common sense” as a hint that they were foolish to ask, so they get defensive or stop asking. Ideally, they make a sensible call on their own.

This one's a judgment call, and I'd like you to make it. Think about what the customer needs and go with what fits best.

Hi Shalini, for small decisions like this, please use your own judgment. If it affects budget or a deadline, check with me first. Otherwise go ahead.

Examples
Hi Joshua, Thanks for checking in on the supplier invoice. For anything under the usual limit, I'd like you to use your own judgment and approve it if the details match the order. If something looks off or the amount is higher than normal, send it to me first. Best, Anita
Quick note on the meeting room bookings: if a slot is free and the team needs it, just book it. You don't need to ask me each time. Only flag it if it clashes with a client visit.
What to avoid
- Putting “obviously” or “clearly” before your point, which tells the person they should have known.
- Sarcasm like “Wow, did you really need to ask?”, which teaches people to stop asking and hide mistakes.
- Correcting someone in front of others, since that turns a small slip into an embarrassment.
- Staying vague about the standard you expect, when people keep missing it and need to hear what good judgment looks like here.
