Qualifier

This exercise entails attaching expertise qualifiers to statements of opinion to be clear about your level of knowledge on a subject. Where appropriate, admit the limits of your knowledge, and when an opinion is stated, advertise that it is your opinion rather than fact. Other qualifiers include stating when you are speculating or theorizing, saying you don't know the answer or the exact figures or details, or admitting that you don't have the source to back up a claim.
