NHS doctor and science writer Ben Goldacre writes about bullshit medical research, bogus science reporting, the placebo effect, and everything else from postmodernism to evolutionary psychology, at his Bad Science blog. His critiques of the health system, pharmaceutical industry, and consumer health fads are extremely relevant - his focus on social factors, economic inequalities, and rejection of reductionist medicalising and/or individualising of what are essentially social/collective issues is pretty consistent with any critique class-struggle anarchists could produce. This is an edited extract from his book Bad Science.
