FIVE CATEGORIES OF CLEAN LANGUAGE

Symbolic Modelling
Symbolic Modelling is a facilitative approach that works with a person’s own metaphors to explore how they experience a situation and how change might happen. Rather than interpreting or reframing, the facilitator stays rigorously with the client’s exact words, asking questions that develop the logic, structure, and implications of their metaphors. The assumption is that people already organise their experience symbolically, and that by attending closely to this symbolic landscape, they can discover shifts that are meaningful and self-generated. The process is precise, often deceptively simple, and requires discipline to avoid adding content or direction.

Clean Space
Clean Space is a spatial method that uses physical location as a way of accessing different perspectives, states, or ways of knowing. A person moves to distinct places in a room and responds to clean questions from each location, allowing insights to emerge from the interaction between body, space, and attention. It is not about analysing or discussing a problem; it is about letting the system organise itself through movement and noticing. When done well, it produces clarity that feels immediate and embodied rather than constructed through reasoning.

Emergent Knowledge
Emergent Knowledge is a distinct set of processes developed by David Grove in his later work. It focuses on enabling new knowing to arise through carefully structured interactions between attention, perception, and environment, rather than through questioning alone. These processes often use space, sequence, and minimal verbal input to allow patterns to reveal themselves without being directed or interpreted. The emphasis is on creating conditions where insight can emerge from the system as a whole—often experienced as immediate, embodied, and not obviously derived from prior thinking.

Clean Interviewing
Clean Interviewing applies clean principles to information-gathering contexts, such as research, evaluation, or journalism. The goal is to minimise interviewer influence so that responses reflect the interviewee’s own framing, language, and meaning-making. Questions are carefully constructed to avoid assumptions, leading language, or implicit interpretations. This approach can reveal nuances that are often lost in more conventional interviewing, but it also demands restraint—particularly the willingness to leave gaps rather than fill them with the interviewer’s perspective.

Systemic Modelling
Systemic Modelling extends clean approaches to groups and organisations, working with the patterns, relationships, and dynamics that exist within a system. It often combines Symbolic Modelling with spatial or representational elements, enabling participants to externalise and explore how a system functions. The emphasis is on making implicit structures visible without simplifying them prematurely. Rather than diagnosing or fixing, the process supports the system to recognise itself more clearly, which can lead to shifts that are both practical and sustainable.
