The arguments of homeopaths often sound like a broken record

Homeopaths tend to voice a standard set of arguments when confronted with irrefutable evidence against homeopathy. In the discussion sections of this blog, we heard them all:

• “The negative trials are flawed designed.” They claim these trials were done by ungifted therapists or used the wrong remedies, wrong potencies, wrong dosing schedules, etc. Therefore, they do not reflect true homeopathic practice.
• “Homeopathy is individualised, RCTs can’t capture it.” They argue that randomised clinical trials are inherently unsuitable because homeopathic treatment must be tailored to each patient, rendering RCTs “unfair” or even “unscientific.”
• “Only a fraction of the evidence has been considered.” They assert that critics cherry-pick negative evidence and ignore positive small trials, case series, or observational data that they regard as equally valid.
• “There is much positive evidence.” They point to older or methodologically weak positive studies and claim these outweigh or at least balance the otherwise negative body of evidence.
• “Meta-analyses and systematic reviews are biased and/or politically motivated.” They allege that negative evaluations are driven by ideological hostility to homeopathy, Big Pharma influence, or institutional bias.
• “Statistical significance is not the same as clinical reality.” They argue that  statistics miss “real-world” benefits observed in practice and that evidence-based medicine is too narrow.
• “Evidence-based medicine overvalues RCTs and undervalues experience.” They insist that long clinical experience, case reports, patient testimonies, etc. should count as strong evidence and that their accumulated practice is itself proof of efficacy.
• “Patient demand and satisfaction are evidence.” They use high patient satisfaction, repeat consultations, and word-of-mouth popularity as a proxy for effectiveness.
• “Millions use it worldwide.” They argue that longstanding, global usage implies that it must work; otherwise it would have disappeared.
• “Conventional medicine is not perfect either.” They respond to criticism by highlighting harms, errors, and historical reversals in conventional medicine, implying that science-based critics lack moral authority.
• “If it were only placebo, it wouldn’t work on XY.” They claim efficacy in infants, animals, or unconscious patients as evidence that placebo cannot fully explain the effects.
• “Mechanisms aren’t fully known, but that doesn’t matter.” They liken homeopathy to earlier medical advances whose mechanisms were unknown at the time (e.g. aspirin), arguing that lack of a plausible mechanism is not a valid reason to reject positive clinical observations.
• “Physics and chemistry are incomplete; future science will explain it.” They invoke concepts like quantum physics, nanostructures, or complex systems to argue that current science is still too limited to explain homeopathy.
• “Regulatory / institutional conspiracies.” They suggest that powerful pharmaceutical or medical lobbies seek to suppress homeopathy to protect their financial interests.
• “Homeopathy is cheap and safe; risk–benefit favours it.” They argue that even if evidence is thin, the very low risk and low cost justify its use.
• “The therapeutic encounter itself is part of the effect.” They turn criticisms about placebo and context effects into a strength: the long consultation, empathy, and attention are claimed to be legitimate and central components of homeopathy.
• “Freedom of choice / patient autonomy.” They shift from scientific to ethical/political ground, insisting that patients should be free to choose homeopathy regardless of scientific consensus.
• “Skeptics misunderstand what homeopathy really is.” They claim that people conflate homeopathy with herbalism, confuse potencies, or misunderstand Hahnemann’s principles, so their critiques do not address true homeopathy.
• “Critics don’t see the individual ‘miracle’ cases.” They counter population-level data with vivid anecdotes of dramatic improvements which they regard as decisive.
• “Negative evidence is ‘absence of evidence’, not ‘evidence of absence’.” They argue that failed trials or negative reviews merely show that efficacy hasn’t been proved yet, not that homeopathy does not work.
• “Science evolves; today’s ‘overwhelming evidence’ may be overturned.” They claim that scientific consensus has been wrong before and that homeopathy will eventually be vindicated when paradigms shift.

In discussions with homeopaths, these points are repeated endlessly. One could easily get the impression of a broken record. All of the above arguments have in common that – even as some of then contain a kernel of truth – they are erroneous. In theory it could be easy to point this out to the stereotypical homeopathy promoter; in practice, however, it often is impossible, since the broken record continues turning senselessly.
