Episode 2: The Irrational Health Service
Richard Dawkins examines the growing suspicion the public has for science-based medicine, despite its track record of successes like the germ theory of disease, vaccines, antibiotics and increased lifespan. He notes a fifth of British children are currently not immunised against measles, mumps and rubella, attributing it to fears arising from a highly controversial report linking the vaccine with autism.
Dawkins criticizes the growing field of alternative medicine which does not pass the same objective and statistical rigour as scientifically derived treatments using controlled double-blind studies. Without verifiable evidence, alternative therapies must rely on biased anecdotes and word of mouth to perpetuate. Dawkins observes these treatments have fanciful rationales and rituals behind them, with many alternative treatments employing pseudoscientific jargon such as "energy", "vibration" or "quantum theory" to give themselves greater credence to patients.
Homeopathy is singled out as an example of a mainstream alternative medicine that has public support and taxpayer funding through the National Health Service. Dawkins explains that the rationale behind it is unfounded and demonstrates that the magnitude of dilution required is so great the patient is practically imbibing pure water. This is illustrated by the typical homeopathic dilution of 30C (1:10030, that is thirty steps of dilution by 1% each time), which requires a drop of active ingredient dissolved in a body of water greater than the whole ocean. Dawkins cites a 2005 meta-analysis by The Lancet that concludes that homeopathy has no consistently demonstrable effect on health.
Dawkins hypothesises that practitioners of alternative medicine spend longer time than regular doctors on their patients when attending to them. An interview with Professor Nicholas Humphrey suggests that this empathic attention may cause a placebo effect in patients, but this is not a substitute for conventional science-based medicine.
The episode concludes with Dawkins making an appeal to skeptical, rational inquiry based on evidence, claiming 'reason has liberated us from superstition and given us centuries of progress. We abandon it at our peril.'

Famous quotes containing the words episode, irrational, health and/or service:
“The press is no substitute for institutions. It is like the beam of a searchlight that moves restlessly about, bringing one episode and then another out of darkness into vision. Men cannot do the work of the world by this light alone. They cannot govern society by episodes, incidents, and eruptions. It is only when they work by a steady light of their own, that the press, when it is turned upon them, reveals a situation intelligible enough for a popular decision.”
—Walter Lippmann (1889–1974)
“The irrational may be attractive in the abstract, but not in cab drives, dinner guests, or elderly relatives.”
—Mason Cooley (b. 1927)
“I think that carrying a baby inside of you is like running as fast as you can. It feels like finally letting go and filling yourself up to the widest limits.”
—Anonymous Mother. Ourselves and Our Children, by Boston Women’s Health Book Collective, ch. 2 (1978)
“Night City was like a deranged experiment in Social Darwinism, designed by a bored researcher who kept one thumb permanently on the fast-forward button. Stop hustling and you sank without a trace, but move a little too swiftly and you’d break the fragile surface tension of the black market; either way, you were gone ... though heart or lungs or kidneys might survive in the service of some stranger with New Yen for the clinic tanks.”
—William Gibson (b. 1948)
