Most histories of psychology weave a story around the rise of objective methods of investigation and the decline of subjective introspection. This paper sidesteps such disciplinary stories by describing self-scrutiny as a practice that moved through a variety of cultural, social and technological contexts in early twentieth-century America. Edmund Jacobson's technique of 'progressive relaxation' is offered as a case in point. Jacobson, a Chicago clinician, developed this cure for nervousness out of his earlier research under E. B. Titchener, an experimental (...) psychologist at Cornell University. Like Titchener's method of 'experimental introspection ', progressive relaxation was a laboratory-based activity designed to transform the practitioner's sensibilities through the fastidious repetition of simple tasks. But while experimental psychologists ultimately rejected introspection as the core of their disciplinary project, the American public embraced progressive relaxation as a practical technique for mastering the new conditions of modernity.

Philosophers tend to assume that we have excellent knowledge of our own current conscious experience or 'phenomenology'. I argue that our knowledge of one aspect of our experience, the experience of visual imagery, is actually rather poor. Precedent for this position is found among the introspective psychologists of the late nineteenth and early twentieth centuries. Two main arguments are advanced toward the conclusion that our knowledge of our own imagery is poor. First, the reader is asked to form a visual (...) image, and it is expected that answering questions about certain basic features of that experience will be difficult. If so, it seems reasonable to suppose that people could be mistaken about those basic features of their own imagery. Second, it is observed that although people give widely variable reports about their own experiences of visual imagery, differences in report do not systematically correlate with differences on tests of skills that psychologists have often supposed to require visual imagery, such as mental rotation, visual creativity, and visual memory.
