Scientific Frauds that Rocked the World.

The Great Tasaday Hoax

One of the most startling anthropological discoveries of the 20th century was the discovery of a primitive, cave-dwelling society in the Philippines in 1971. The Tasadays, as they were called, were a find of enormous proportions because they lived a life undisturbed by hundreds of years of society. And to many an academic’s delight, anthropologists could now directly observe how people lived in such societies. The Tasadays even used stone tools.

If you’re thinking it’s impossible that such an isolated group could exist in the Philippines as late as the 1970s, you’re right. It turns out that their "discoverer," PANAMIN (Private Association National Minorities) secretary Manuel Elizalde Jr., paid local farmers to live in the caves, take off their clothes, and appear Stone Age. In return he gave them money and security from counterinsurgency and tribal fighting.

The fact that the Tasaday were a hoax was not confirmed until the fall of Marcos in 1983, invalidating, no doubt, many PhD dissertations that had been written in the interim.
