Nuhn et al (2010) have found that the placebo effect in homeopathy is not larger than in conventional medicine when comparing classical homeopathy to conventional medicine. The lengthy case-taking process and empathy shown by the practitioner does not account for an increased placebo effect (as is claimed by critics of homeopathy).

Let's see how quick the denialists tell us that this research is no good!
