“Focusing” is a practice of introspection systematized by psychotherapist Eu- gene Gendlin which seeks to build a pathway of communication and feedback between a person’s “felt sense” of what is going on (an internal awareness which is often difficult to articulate) and their verbal explanations. It can be understood as a method of querying one’s inner simulator (and related parts of System 1). Gendlin’s (1982) book Focusing provides a guide to this technique, which can be used either individually or with others (in therapy or other debugging conversations).
