The term "Weber-Fechner law" is arguably the most widely used misnomer in psychological science. The unification reflects a failure to appreciate the logical independence and disparate implications of Weber's law and Fechner's law as well as some closely aligned ones. The present statement, long overdue, is meant to rectify this situation. I discuss the roots and derivations of the relevant laws, eschewing formalism to bare essentials for sake of wider accessibility. Three of the most important conclusions are (a) Weber's law is not indispensable for deriving Fechner's law; (b) arguably, Fechner himself did not use Weber's law in his original derivations; and (c) many investigators mistake the principle that subjective distance is determined by physical ratio for Weber's law. In truth, the principle, here called the Weber principle, and Weber's law, are different and independent. I stress the importance of drawing the distinction and illustrate confusions in the literature coming from misapplications of Weber's law and the use of misnomer.

韦伯-费希纳定律：一个持续存在但应该消失的用词不当。

术语“韦伯-费希纳定律”可以说是心理科学中使用最广泛的用词。统一反映了未能理解韦伯定律和费希纳定律以及一些紧密结合的定律的逻辑独立性和不同含义。早该发表的本声明旨在纠正这种情况。我讨论了相关法律的根源和派生，为了更广泛的可访问性，避免形式主义而只谈基本要素。三个最重要的结论是 (a) 韦伯定律对于推导费希纳定律并不是必不可少的；(b) 可以说，费希纳本人在其原始推导中并未使用韦伯定律；(c) 许多研究者将主观距离由物理比例决定的原则误认为是韦伯定律。其实原理，这里叫做韦伯原理，和韦伯定律，是不同的，是独立的。我强调了区分的重要性，并说明了由于韦伯定律的误用和用词不当而引起的文献混淆。（PsycInfo 数据库记录 (c) 2021 APA，保留所有权利）。
