Sacred cows to the slaughter

As UFO debunker Robert Sheaffer's web site proclaims, he's "skeptical to the max." He is a fellow of the Committee for the Scientific Investigation of Claims of the Paranormal and a well-known writer on the UFO scene.

Being an equal-opportunity debunker, Sheaffer notes that he refutes whatever nonsense, in his judgment, "stands in the greatest need of refuting, no matter from what source it may come, no matter how privileged, esteemed, or sacrosanct ... sacred cows, after all, make the best hamburger."

Sheaffer told SPACE.com, in regard to the cottage industry of UFO promoters, there's a reason there are still so many snake-oil sellers.

"It's because nobody, anywhere, has any actual facts concerning alleged UFOs, just claims. That allows con-men to thrive peddling their yarns," Sheaffer said. "UFO believers are convinced that the existence of UFOs will be revealed 'any day now'. But it's like Charlie Brown and the football: No matter how many times Lucy pulls the football away-or the promised 'disclosure' fails to happen-they're dead-certain that the next time will be their moment of glory."
