It’s mythical. It doesn’t change the outcome of patients with all cancers, infectious diseases, hair loss, blood disease, psoriasis, eye vision loss, bone loss, weight gain loss, and so on. These can all be objectively measured without a concern for blinded study participants that in the Hawthorn effect can over power the outcome with positive thinking. See you don’t question the methodology just accept it as if the world is flat now let’s just move on…lol! As humans we continue to repeat the same mental traps as our ancestors.
