Public perception that if scientists express uncertainty, they “don’t know they are talking about.”. “The . scientist has a lot of experience with ignorance and doubt and uncertainty, and this experience is of very great importance, I think. . When . a scientist does not know the answer to a problem, he is ignorant. When he has a hunch as to what the result is, he is uncertain. And when he is pretty damn sure of what the result is going to be, he is still in some doubt. OUTLINE. Accelerator Pre-alignment background. Uncertainty and GUM supplement 1.
