Ah, the illusion of the neutral observer. As if the doctor and the whole environment don't exist and examine the patient in some kind of vacuum.

Happens here every day with blood pressure. By the time you get to that point, you're thoroughly deurinated by having to wait, by seeing staff walking around, taking their friends, kin, neighbors and highest bidders far before their turn (thus increasing your wait), seeing how much ridiculous paperwork is required and how guilty you need to be because yours is in so bad a shape... your blood pressure skyrockets. Some doctors accept this and don't take it until they were with the patient at least fifteen minutes, calmed her down and cheered her up, or they take it immediately and then again in the end. The difference is drastic - which they don't learn in their schools. Most of the doctors think blood pressure changes perhaps daily, and believe so firmly - to the point that they even refuse to do the simple experiment and measure twice and see for themselves.

And the deurinated patient, of course, gets worse by just hearing that the pressure is high. So there's a lot of wisdom in those laws, even though it somehow confuses science with religion.
