在我们作为国际同行评审期刊编辑的集体经验中，我们建议不应将为单个期刊计算的影响因子用作评估单个科学家过去表现或科学潜力的重要性的基础。有几个原因不能将科学家发表的期刊的影响因子与科学家的研究质量等同起来。例如，最近发表的几份影响因素分析报告（1-6）显示：d期刊的影响因素取决于其已发表稿件中的少数人。因此，影响因子与单个手稿的引用相关性很差。d影响系数不考虑在特定专业领域积极从事研究的科学家人数。事实上，一些期刊认为有必要为参与者人数相对较少的群体服务，这些群体继续解决重要问题，即使可供引用的科学家人数有限。d期刊的影响因子可能因期刊的某些做法而被夸大，例如发表许多评论文章。d影响因子仅衡量被引用的频率，不能假定被引用的频率总是等同于质量，我们认为，还有其他更有效的衡量单个科学家发表论文的质量和影响的方法。首先，通过几种类型的互联网搜索引擎，可以很容易地获得个别候选人的引文记录。第二，应该严格执行历史悠久的做法，即征求科学同行对候选人工作重要性的评价，这些同行是经过精心挑选的，既要高素质，又要与候选人保持明确的“距离”。
In our collective experience as editors of international peerreviewed journals, we propose that the impact factor calculated for individual journals should not be used as a basis for evaluating the significance of an individual scientist’s past performance or scientific potential. There are several reasons not to equate the impact factor of a journal in which the scientist publishes with the quality of the scientist’s research. For example, as revealed by several recently published analyses of the impact factor (1–6): d A journal’s impact factor is determined by a decided minority of its published manuscripts. Thus the impact factor correlates poorly with the citations of an individual manuscript. d The impact factor does not consider the number of scientists actively producing research in a given specialty field. Indeed, some journals feel the need to serve constituencies with relatively small numbers of participants who continue to address important questions even though the number of scientists available for citations is limited. d A journal’s impact factor can be inflated by certain journal practices, such as publication of many review articles. d Impact factor measures only the frequency of citations, which cannot be assumed to always equate with quality.There are alternative and, we believe, more valid measures of the quality and impact of an individual scientist’s published contributions. First, a citation record for the individual candidate is readily available through several types of Internet search engines. Second, the time-honored practice of soliciting evaluations concerning the significance of a candidate’s work from scientific peers who are carefully selected to be both highly qualified as well as clearly ‘‘arms-length’’from the candidate should be rigorously applied.
