I think you'll find there is abundant evidence that the type of treatment given matters a great deal. It may not be the only factor, but it certainly is a very, very important factor.Wouldn't matter what treatment is given
Surprising a doctor does not constitute not a miracle. Data are normally distributed. When considering those who exceed predictions, you must also consider those who deteriorate quickly.And if someone is strong willed enough with positive thought they can defy medical practitioners' hopeless prognostications.
Clinical trial data does support the ability of placebo to affect perceptions of disease, particularly pain and depression, which suggests a role for positive thought in medicine. But there is little data to support the power of prayer or positive thought alone, and for all medicines approved for use, they must be superior to placebo, that is to positive thought, alone. Where positive thought is associated with better outcomes, it always disappears with multivariate analysis (suggesting the association is driven by people who areless likely to die feeling more positive, rather than more people who are more positive being less likely to die).
But your argument seems to be that only weak willed, negative people die. This is utterly ridiculous.
