When one is given something they are told does not work for a stated purpose, ever...yet, miraculously works for exactly the purpose that it was stated to never work. While symptoms may not dissipate entirely, the root cause is cured entirely. Similarly to Tim Tebow as an NFL quarterback leading his team to wins despite the naysayers. Opposite of the placebo effect.

K: Yea, man. MJ is medicinal.
M: But that phd I was dating said it has no medicinal value!
K: Platebow effect. MJ delivers, always. Ignore the naysayers.
