-34 Figure 4: The systemic loop process model.62 The systemic loop highlights the importance of constant reflection and (self-) reflection. This is done through “Building hypotheses” (or “Clarifying assumptions”), which is a critical part of systemic practice. This critical reflection is also a feature of “Theory-of-change” approaches, nowadays in common use.63 Importantly, this includes looking at one’s own role in the process. Basically, hypotheses are assumptions about connections and relational patterns that need to be tested. “Systemic hypotheses describe relationships, interaction, reciprocal effects and processes, they refer to different contexts, focus on resources and solutions and often seem unconventional. They try to uncover the hidden meaning behind problems. They have explanatory power.”64 The systemic functions of hypotheses are two-fold: • They help systematise and prioritise information • They stimulate thinking about options for intervention. The tool of hypothesizing can be extremely helpful, both for the purpose of describing a problem (“The reason for the negative attitude of staff towards detainees could be their poor working conditions…”) as well for identifying possible solutions (“The attitude towards the detainees could change if the staff had shorter working hours, longer recovery 62.
