Affirming the consequent is always an interesting one to me when it overlaps with a tragedy of the commons situation. If publicly available content can be used in training sets, any one model willing to use them will have an advantage. Is it reasonable to assume then that all publicly available content is in the most popular training sets, or is that falling into the affirming the consequent fallacy?
