Etymology

   • 1961 September, Walter P. Kennedy, “The Nocebo Reaction”, in Medical World, volume 95, London: Medical Practitioners' Union, →ISSN, →OCLC, →PMID, page 203:

     It is somewhat surprising that little attention has been drawn to the existence of the contrary effect [to the placebo] – which I may call the nocebo reaction.

   • 2009 April 25, Stuart Blackman, “Why health warnings can be bad”, in Financial Times:

     In the case of the nocebo, it is negative expectations that become self-fulfilling prophecies.

   • 2014 May 15, Jennifer Welsh, “Researchers who Provided Key Evidence for Gluten Sensitivity have now Thoroughly Shown that It Doesn’t Exist”, in Business Insider‎^[1], archived from the original on 2 July 2017:

     It seems to be a "nocebo" effect – the self-diagnosed gluten sensitive patients expected to feel worse on the study diets, so they did.

   • 2020, Rutger Bregman, Humankind‎^[2], Bloomsbury Publishing, →ISBN:

     If there's one lesson to be drawn from the nocebo effect, it's that ideas are never merely ideas. […] Maybe you see where I'm going with this: our grim view of humanity is also a nocebo.
