I always make intuitions regarding the future, sometimes good and sometimes bad, and most of the time they are likely to be proven true. So what would a person be called whose intuitions always become true and happen?
In such a case you are prescient.

"All right, if it makes you feel any better."
"Um, Mrs. Cake? I'm finding it a little confusing. Could you...switch off...your precognition...?"
from: The Reaper Man, by Terry Pratchet
(context: Mrs. Cake has the ability of precognition, so she answers Windle's questions before he has the chance to ask them.)
