目标。评估设计的更有意义的表述方法是否会导致决策中质量信息的更大权重。一项新兴的研究表明，信息的呈现方式会影响信息的解释方式以及在决策中的权重。消费者没有使用比较健康计划执行情况报告，可能是因为所提供的信息难以使用。这些报告的下一代应旨在支持决策。设计和研究参与者。该研究采用对照实验设计。参与者（n = 162）被随机分配到不同的条件，并被要求完成与使用质量信息和做出健康计划选择相关的任务。因变量包括体重。在选择和决策准确性方面给予质量信息。结果。一些表示方法使用户更容易处理和将高质量数据集成到他们的选择中。然而，其他的展示形式会以损害消费者自身利益的方式影响他们的决定。研究结果表明，以更可评估的格式呈现高质量的数据增加了它在消费者决策中的权重。在比较数据的表示方式上所作的每一项改变都有可能影响决策。传播信息的人有责任了解他们如何利用这种影响，并以有效和合理的方式引导这种影响。另一种方法是用未知的、未经深思熟虑的或无法辩护的方式操纵人们，但同样具有操控性。
Objective. To assess whether presentation approaches designed to be more meaningful result in greater weighting of quality information in decisions. An emerging body of research indicates that the way information is presented affects how it is interpreted and how it is weighted in decisions. Comparative health plan performance reports are not being used by consumers possibly because the information presented is difficult to use. The next generation of these reports should be designed to support decision making.Design and Study Participants. The study uses a controlled experimental design. Participants (n = 162) were randomly assigned to different conditions and asked to complete tasks related to using quality information and making health plan selections. Dependent variables included the amount of weight. given to quality information in choices and decision accuracy.Results. Some presentation approaches make it easier for users to process and integrate quality data into their choices. However, other presentation formats influence consumers' decisions in ways that undermine their self-interest.Conclusions. Findings indicate that presenting quality data in a more evaluable format increases the weight it carries in consumer decisions. Every change made in the presentation of comparative data has the potential to influence decisions. Those who disseminate information have a responsibility to be aware of how they use that influence and to direct it in productive and defensible ways. The alternative is to manipulate people in ways that are unknown, are not thought out, or are not defensible, but are no less manipulative.
