It's not so much a hoax as just bad science, the result of which has been popularised (through references in fiction, for example) and taken (by too many) as being true, despite the reality. Even the author of the study said that many more such tests would need to be done before any conclusion could be reasonably reached. There has been no deliberate effort to hoodwink the public, so no hoax. Just Joe Public not fact-checking what they are otherwise happy to spread. Maybe next time you should check such claims before claiming them as truth? Please Register or Log in to view the hidden image!
