A randomized controlled trial (RCT) is a type of scientific experiment - a form of clinical trial - most commonly used in testing the safety (or more specifically, information about adverse drug reactions and adverse effects of other treatments) and efficacy or effectiveness of healthcare services (such as medicine or nursing) or health technologies (such as pharmaceuticals, medical devices or surgery). The key distinguishing feature of the usual RCT is that study subjects, after assessment of eligibility and recruitment, but before the intervention to be studied begins, are randomly allocated to receive one or other of the alternative treatments under study.

An RCT may be Blinded, (also called "masked") by "procedures that prevent study participants, caregivers, or outcome assessors from knowing which intervention was received."[36]

RCTs without blinding are referred to as "unblinded"[39], "open"[40], or (if the intervention is a medication) "open-label"[41]. In 2008 a study concluded that the results of unblinded RCTs tended to be biased toward beneficial effects only if the RCTs' outcomes were subjective as opposed to objective[36]; for example, in an RCT of treatments for multiple sclerosis, unblinded neurologists (but not blinded neurologists) felt that the treatments were beneficial[42]. In pragmatic RCTs, although the participants and providers are often unblinded, it is "still desirable and often possible to blind the assessor or obtain an objective source of data for evaluation of outcomes."[27]

To be honest, I really don't think this sort of thing requires a controlled test, except for fun

I find amusement in trying out those demos and trying to figure out whether the presenter is a charlatan or just another sucker.
