Just watched the second part of Enemies of Reason. This week the target was 'alternative' medicine, such as homeopathy, acupuncture etc. Dawkins pointed out that 80% of these have never been subjected to properly conducted trials and quite rightly (and obviously) concluded that if any of them benefit their patients, it is almost certainly due to the placebo effect - i.e. the users want the 'remedies' to work.
That wouldn't be a problem, but it is the complete disregard (and disrespect) for scientific principles that is worrying, fuelled by unfounded media attacks on science, such as the hysteria over the alleged dangers of the MMR vaccine (which has since caused considerable suffering, including measles outbreaks and one death). Of particular concern to me was the doctor who claimed that we all have black holes inside of us that affect our health, despite having no evidence for this theory - you might as well theorise that sleeping with a teapot cures the common cold. As for ancient remedies, Dawkins reminded us that just because they are long-standing, that does not make them right, as with all beliefs.
Most scary, though, was Deepak Chopra, who openly disputed science and the scientific method, and apparently counts among his followers Hillary Clinton, who could be the next President of the United States.
