levels of uncertainty

I was really bored and this funny thing popped into my head. Let's say that a person is answering a yes or no question in real life, not on a survey. Here are what I believe to be the levels of uncertainty.

1st level: "Probably."

2nd level: "Maybe."

3rd level: "I don't know."

4th level: "Probably; maybe."

5th level: "Probably; maybe; i don't know!"

Unless asking a impressionable, teenage adolescent. Then all of these mean the morally wrong answer of the two.

Thank God I'm not impressionable.
