Placebos DON’T work. The placebo ‘effect’ is the effect they have on clinical studies - they confound them. This is not an indication that they have a valid therapeutic effect, because they don’t. Whatever effect they have is temporary and non therapeutic.
The ‘power’ of the placebo is the ‘power’ of the witch doctor, the ‘power’ of the quack. To argue that they can be used ethically is nonsense and the opposite of ethical medicine.
