Skeptical author Robert Sheaffer believes the phenomenon at Skinwalker to be "almost certainly illusory", given that NIDsci found no proof after several years of monitoring, and that the previous owners of the property, who had lived there for 60 years, say that no supernatural events of any kind had happened there. Sheaffer considers the "parsimonious explanation" to be that the Sherman family invented the story "prior to selling it to the gullible Bigelow", with many of the more extraordinary claims originating solely from Terry Sherman, who worked as a caretaker after the ranch was sold to Bigelow.[12]

In 1996, skeptic James Randi awarded Bigelow a tongue-in-cheek Pigasus Award for funding the purchase of the ranch and for supporting John E. Mack's and Budd Hopkins' investigations. The award category designated Bigelow as "the funding organization that supported the most useless study of a supernatural, paranormal or occult [claim]".[13]

In 2023, ufologist Barry Greenwood, writing in the Journal of Scientific Exploration, criticized the $22 million research program led by James Lacatski. He emphasized the lack of any documentary evidence from the ranch after many decades of exploration and characterized Skinwalker as "always in the business of selling belief and hope".[14]
