my understanding (see references in linked page) is that when one does what you said and compare placebo to “nothing”, almost the entire effect goes away.

- fooblat 7y agoHow would you propose a blinded study will work to compare between a Placebo treatment and no treatment?
- heisenzombie 7y agoOne way is to use waiting list controls.
- henearkr 7y agoTo compare placebo vs nothing (i.e. no placebo), you don't need the double-blind requirement. Because the group receiving nothing is not receiving the placebo, and thus does not (and should not) benefit from any illusion of having being treated.
- henearkr 7y agoIf we can verify that (I really hope so) it would be great news. Because the tests would be much simpler, and maybe costs and duration would become 1/10 of what they are today or even much less. The double-blind requirements are really a pain.
