Most people seem to assume that part of the reason that alternative treatment and unacknowledged diseases couldn't possibly be real is because they think that as big and important of a process as that which determines which diseases/treatments are preferable must be unbiased and scientific, or at least mainly motivated by good science. In fact, the opposite is true, and we have a situation where the entire scientific process of mainstream medicine is determined more by money and economic clout than by scientific pursuit, via various corrupt regulatory agencies, licensing practices, research grants, monopolized university education, etc. The system is totally monopolized and rigidly controlled.
No amount of research or careful argumentation will convince people who engage in scientism about the existence of Morgellon's disease because the mainstream scientific consensus, which they see as a more or less objective measure, does not acknowledge Morgellon's. It is this consensus that matters to the scientistic person, not the actual evidence itself.
