Purple hat therapy

In imaginary purple hat therapy, a person being treated is required to wear a purple hat, but it is not responsible for any effectiveness the treatment has.

Purple hat therapy refers to any medical practice in which an established form of therapy is mixed with an unlikely new addition (such as wearing a purple hat) and then is claimed to be effective because of the new addition, when in fact the effectiveness is due to the established component.[1]
