At what degree of certainty are we incredulous?

I'm asking because I'm not incredulous about something I recognize I cannot prove, and want to put a degree of certainty on it.

Many good questions generate some degree of opinion based on expert experience, but answers to this question will tend to be almost entirely based on opinions, rather than facts, references, or specific expertise.

  • Language doesn’t work like that. Words aren’t quantifiable. You are incredulous about something if you don’t lend it credence; that’s the extent of the interpretability of the word. There is no “when your belief level is > 7.61” statement possible. – Dan Bron Oct 22 '17 at 19:41
  • How would slapping a number on something you are unsure about (incredulity threshold?) make you any less unsure about it? And why do you assume that this supposed threshold will be uniform across different types of beliefs? See SEP on certainty and subjective probability – Conifold Oct 22 '17 at 22:10
  • @Conifold hmm good point about different types of beliefs – user28660 Oct 23 '17 at 13:17
  • There is no such thing as degree of certainty. You are using the word too loosely. Cerainty means no chance of error. A degree or probability means there is no certainty but some result is likely to happen. The degree or percent informs you how likely you get the result. I am not certain to win mega million but my odds are . . If i am certain i will win the next mega million there us no way for me to lose. – Logikal Oct 28 '17 at 0:02
