Placebos and placebo effects have generated years of conceptual confusion about what kinds of thing they are.[22][23][24][25][26] Example definitions of a placebo may refer to their inertness or pharmacological inactivity in relation to the condition they are given for. Similarly, example definitions of placebo effects may refer to the subjectivity or the non-specificity of those effects.[27] These type of definition suggest the view that when given a placebo treatment, one may merely feel better while not being ‘really’ better.
