erring on the side of caution

Choosing careful action

Erring on the side of caution means choosing the safer or more conservative option when facing uncertainty.

The phrase treats excessive caution as a minor error preferable to the alternative: When in doubt about the medication dosage, err on the side of caution and call the doctor.

The logic is that if you must make a mistake, make the one with smaller consequences.
