You probably know me as the horror writer behind books like Carrie, IT, and The Shining.
Since I write horror novels for a living, I feel I have some authority when I say that four more years of Donald Trump in the White House would be an absolute nightmare.
~ Stephen King
Steve, back to the topic.
The above quote from Mr. King is funny but at the same time is an example of a logical fallacy.
More precisely, his undeniable skills in writing horror stories do not entail skills in being clairvoyant, in foreseeing the future, even though putatively horrific.
He makes an appeal to authority but his authority entails only book-writing, not political forecasting.
