(What follows is a very rough summary of some of the findings from my work on my Masters dissertation).
While trying to understand thought insertion I became aware of the lack of first person descriptions in the philosophical literature. I didn’t understand the phenomenon and didn’t feel that the philosophical literature helped me, as it was full of contradictions. I felt I couldn’t make progress without more information. In my work in this area I rely heavily on what patients and others say about their experience (using mental health web forums and other first person descriptions) and take their description of their experience seriously.
