公信力

传统意义上，公信力有两个基本要素：可信度和专业度，两者都由主观和客观组成。可信度更多地建立在主观因素基础上，但也包括客观衡量标准，如公认的可靠信息。专业度同样可被主观感知，同时也包括相关信息的客观的特征，如凭证、证书和信息质量等。[1]公信力的次要要素包括信息来源的活力和吸引力。

公信力指对信息或其来源可信度的主观及客观组成。

1990年代中期开始，网络已成为一个重要的信息源，网络公信力也因此成为一个重要的研究课题。加州大学圣巴巴拉分校公信力和数字媒体工程正进行此方面的研究，并将其列为近期研究重点。研究内容包括数字媒体、青年人和公信力。此外，斯坦福大学的科技说服者实验室页面存档备份，存于也已展开网络公信力的研究，并提出网络公信力的主要组成和概述性理论--显释论页面存档备份，存于。

新闻公信力

根据职业记者协会制定的道德守则，职业操守是记者公信力的基石。（参阅前言页面存档备份，存于）

科学公信力

科学公信力被定义为，可提供公认可靠信息源的一般科学的延伸。[2]该术语也做狭义用，如针对科学家或某一领域研究的公信力评估。此地，科学公信力指研究成果是否遵循科学原理。[3]评估科学成果质量最常用的方法是同行评审和科学著作的发表。[4]其他方法也包括由一组专家共同评估，这一方法的能够产生很多专业的评论，发表在科克伦协作网[5]和政府间气候变化专门委员会[6]之类的网站上。

社会大众左右着争议性问题的科学权威判断，如生物技术。[7]同时，科学的公信力和权威性受到非主流观点的质疑。他们鼓吹替代医学[8]，质疑科学共识（如提出艾滋病重估运动）。[9][10]
