Subjects experiencing thought insertion disown thoughts they are introspectively aware of. According to what I call “the rationality hypothesis”, thought-insertion reports are not merely intelligible, but also express, or potentially express, fully rational judgments in the light of highly disruptive experience. I argue that the hypothesis is ethically and theoretically motivated, and provides two insights into the philosophical significance of reports by subjects with schizophrenia. First, the reports can be seen as evidence that rational judgments of ownership of a thought (...) prioritize agency awareness over introspective awareness of it. This point fits with an integrative account of thought insertion at the personal and mechanistic levels. Second, rational and competent uses of the first person purely based on introspection do not necessarily involve a full-fledged first-person perspective over one’s thoughts. This suggests that agency awareness, and not introspection as such, is primarily involved in determining the reference of the first person featuring in the judgments. (shrink)

There are a number of conflicting accounts of thought insertion, the delusion that the thoughts of another are inserted into one’s own mind. These accounts share the common assumption of realism: that the subject of thought insertion has a thought corresponding to the description of her thought insertion episode. I challenge the assumption by arguing for an anti-realist treatment of first-person reports of thought insertion. I then offer an alternative account, simulationism, according to which sufferers merely simulate having a thought (...) inserted into their heads. By rejecting realism, the paper undermines a widespread explanatory framework that unites otherwise competing cognitive models of thought insertion. (shrink)
