We challenge the unquestioning pursuit of the appearance of objectivity and ingrained designer-user dualism in human-centred design research and propose a resurrection of introspection as a valid approach to investigating subjective experiences. Through comparing epistemic perspectives and reviewing the histories of introspection in several disciplines, we liberate the research field of experience-driven design from a long-lasting doubt about and the disguised and unsystematic use of this method. To establish a foundation for the further development of introspective methods, we focus on (...) its most controversial type (i.e. researcher introspection) and discuss its strengths and weaknesses, preconditions of use, diverse ways to practise for different suitable experiencedriven design research purposes, and useful techniques and tools.
