The present study examined whether health information is judged differently depending on pre-existing beliefs and expectations. People's initial beliefs and expectations were assessed by a questionnaire about acupuncture and a trustworthiness and preference rating task of doctors' faces. Then, newspaper headlines about novel acupuncture treatment were shown and rated for their feasibility in a normal and framed condition. The judged feasibility of the newspaper headlines correlated strongly with initial beliefs about acupuncture in the normal condition, and with initial expectations towards a doctor's face in the framed condition. Thus, as suggested by Bayes Theorem, pre-existing beliefs and expectations influence judgments of novel health information.
本研究考察了健康信息是否会因预先存在的信念和期望而有所不同。通过一份关于针灸的问卷和一份医生面部可信度和偏好评分任务来评估人们的初始信念和期望。然后，展示有关新型针灸治疗的报纸头条，并在正常和框架条件下对其可行性进行评分。在正常条件下，报纸头条的可行性判断与对针灸的初始信念密切相关，而在框架条件下，与对医生面部的初始期望密切相关。因此，正如贝叶斯定理所表明的，预先存在的信念和期望会影响对新健康信息的判断。
