pessemystic
More ready to discount/ignore/criticize a fortune-teller's work than to support or trust it.
I used to be devoutly "OPTImystic" in previous years. but then when I learned that so many of these mediums had been famously busted as frauds, I eventually became decidedly "pessemystic", especially after a few of my own friends lost sizeable fortunes through said quacks' phony activities. In fact, nowadays the whole subject actually makes me "pissemystic" sometimes, in that I partially lose bladder control on some occasions when I hear about yet another cards-and-incense charlatan embroiled in yet another scandal.
