The evidence supporting this article is scarse indeed. The physical description of the device is sourced to a blog, which is by its nature not a reliable source. The historical evidence refers to several devices that are called collars, but which the author insists are really this "iron bit" device, with no evidence to back up this connection. The Social Implications section appears to be the author's own conclusion, which would constitute original research. I urge the author to address these issues.
