Conditionals and conditional reasoning have been a long-standing focus of research across a number of disciplines, ranging from psychology through linguistics to philosophy. But almost no work has concerned itself with the question of how hearing or reading a conditional changes our beliefs. Given that we acquire much-perhaps most-of what we believe through the testimony of others, the simple matter of acquiring conditionals via others' assertion of a conditional seems integral to any full understanding of the conditional and conditional reasoning. In this paper we detail a number of basic intuitions about how beliefs might change in response to a conditional being uttered, and show how these are backed by behavioral data. In the remainder of the paper, we then show how these deceptively simple phenomena pose a fundamental challenge to present theoretical accounts of the conditional and conditional reasoning - a challenge which no account presently fully meets.

条件和证词

条件句和条件推理长期以来一直是许多学科的研究重点，从心理学到语言学再到哲学。但几乎没有作品关注听或读条件如何改变我们的信念的问题。鉴于我们通过他人的证词获得了很多——也许是大部分——我们相信的东西，通过他人对条件的断言获得条件的简单问题似乎是对条件和条件推理的任何充分理解不可或缺的一部分。在本文中，我们详细介绍了一些基本直觉，即信念如何随着条件的发出而发生变化，并展示了这些是如何得到行为数据的支持的。在论文的其余部分，
