The default effect in end-of-life medical treatment preferences.
Living wills are intended to preserve patient autonomy, but recent studies suggest that they do not always have their desired effect. One possible explanation is that living wills do not capture the authentic preferences of the patients who write them but instead reflect transient contextual effects on preferences. ⋯ The default manipulations in both experiments had potent but transient effects and influenced what participants wrote in their living wills but not their responses to later medical scenarios. Expression of end-of-life treatment preferences appears to be temporarily constructed from the decision-making context. These results have implications for surrogate decision making and the use of the living will as a tool to preserve patient autonomy.

Current guidelines for surgeons' decisions about whether to offer cosmetic surgery are ineffective. Therefore, surgeons have to make difficult decisions on a case-by-case basis. The authors sought to identify the patient variables that influence surgeons' decisions in practice. ⋯ Surgeons' decisions about whether to offer elective cosmetic surgery follow systematic rules. By incorporating the factors that surgeons use in their decision making, more effective guidelines about elective cosmetic surgery provision than are presently available could be developed.
