How do expectations apply to LDing? What are the limits of expectation effects on LDing induction ? That is, how proficient can we become just by the workings of expectations ?

Is there a placebo effect on LDing induction ? If there is such an effect can we convince ourselves that LDing is easy because it is subject to placebo effect, and so is heavily dependent on mindset ?

* PS: Last week i have experienced what i believe to be a placebo effect from a drug, and now i am curious about expectations and the placebo effect.
