    "title": "The elusive oddness of or-introduction",
    "subtitle": null,
    "abstract": "The inference of or-introduction, p, therefore p or q, is\nfundamental in classical logic and probability theory. Yet\ntraditional research in the psychology of reasoning found that\npeople did not endorse this inference as highly as other one-\npremise valid inferences. A radical response to this finding is\nto claim that or-introduction is in fact invalid. This response is\nfound in the recent revision of mental model theory (MMT).\nWe argue that this revision of the theory leads to a number of\nlogical problems and counterintuitive consequences for valid\ninferences, and present an experiment extending recent\nstudies showing that people readily accept or-introduction\nunder probabilistic instructions. We argue for a pragmatic\nexplanation of why the inference is sometimes considered\nodd. The inference is not odd when people reason from their\ndegrees of belief.",
