Here is a topic that doesn't get much attention in the world of Bigfoot.
What are we to make of the motive of hoaxers who create Bigfoot tracks? I'm guessing there are different motives at play. These come to mind:
a. The trickster and mischief maker.
These hoaxers' motive is simple, create a hoax for the pure fun in confounding people. I think Rant Mullins and Ray Wallace are two good examples of the trickster mentality. Also, since they were the early pioneers of tracks eventually attributed to “Bigfoot,” we can understand why an alleged giant ape possessed very human-like feet. Mullins had begun hoaxing tracks in the 1920s, before Bigfoot, and we can see he was creating trackways of giant humans, either based on European giant lore or giant Indian lore (i.e., “sasquatch”), not monster apes, and his concept was later copied by others, including Wallace in Northern California in the 50s. Once Green brought his sasquatch-yeti hybrid with him from Canada, Wallace's tracks became ape tracks, and Wallace, ever the trickster, adopted the notion.
b. The famous Bigfoot advocate.
These hoaxes are created by Bigfoot believers for fame and fortune and for advancing the case for Bigfoot. I see Roger Patterson, Ivan Marx, and Paul Freeman as the best examples of this type of hoaxer. It would not be enough to plant evidence for others to discover, they wanted to be part of the action themselves. They wanted to be the discoverers, the one's seen by others as contributing in an important way to solving the great mystery of Bigfoot. Both Patterson and Freeman wanted to verify the Beast's existence, an existence they didn't doubt, even if it meant cheating and creating the illusion of verification by their hand. Patterson and Marx also had a very strong monetary motives for creating hoax tracks and videos.
c. The suffer-the-fools track maker.
This anonymous hoaxer would have a dim view of the gullibility of people and would derive satisfaction from creating outrageous tracks that are in turn believed to be the real deal by some folks, thereby reinforcing the hoaxer's cynicism about the human race.
d. The anti-science hoaxer.
This hoaxer would be motivated by what could be described as an anti-science bias. He may be a pseudo-Fortean who believes science is taking all the “magic” out of explanation, a “reducing the world to atoms-in-motion” type of argument, and he wants to add a little of the inexplicable to nature to confound the “know it all professors.”
e. Advancing the idea of Bigfoot.
For whatever reason, this hoaxer just wants to contribute to building a physical case for the existence of Bigfoot.
