It seems that the OP is rather speaking about situations where the effect is purely psychological anyway, but wants to distinguish whether it is "real" or "biased". As with "having a dog will make you happy because interaction with dogs satisfies human inherent desires" vs. "having a dog will make you happy because you expect it to be the case". Even if you managed to create a mock-dog capable of fooling the subjects into thinking that it was real, it would miss the point.

Right. Or from another angle: people who do not have dogs are considered pariahs, so the dogless are getting a nocebo all the time. So when they take the placebo (dog) their increase in well being would mostly be through the elimination of the nocebo effect.
