Mental Model Mapper

Surface beliefs, assumptions, stories, and values shaping a system. Use when deeper mental models need examining with care and evidence.

What it does

Surfaces the beliefs, assumptions, stories, values, identities, fears, and definitions of success that shape a system. A mental model is not merely an opinion. It is a way of interpreting reality that influences what people notice, what they treat as normal, what they design for, and what they consider possible.

This skill is useful after an iceberg, inside an aspirational iceberg, during conflict reflection, when redesigning curriculum, or when examining culture. It helps students and adults say: "What are we assuming? What story is operating here? What structures does that story keep alive? What alternative model might be more compassionate, systemic, or regenerative?"

The evidence behind it

Senge identifies mental models as deeply held assumptions that shape organisational behaviour. Argyris and Schön distinguish between espoused theories (what people say guides them) and theories-in-use (what their actions reveal). Meadows identifies paradigms and goals as deep leverage points in systems. Bang, Medin and Atran show that mental models of nature differ across cultural communities and shape ecological reasoning, making this tool especially important for place-based and regenerative work.

How to use it in your lesson

For the best results with EvidenceLesson, give it:

• system_focus — The issue, aspiration, decision, curriculum area, conflict, or place-based system to examine
• context — Where the system exists and who is involved
• visible_evidence (optional) — Events, language, routines, artefacts, or decisions that may reveal mental models
• stakeholders (optional) — Groups whose mental models may differ
• purpose (optional) — Whether the goal is reflection, redesign, conflict repair, curriculum planning, or action

Known limitations

1. Cannot confirm what people actually believe. All mental models are inferences from visible evidence — language, routines, artefacts, decisions. The skill produces hypotheses, not confirmed beliefs. Do not present outputs as psychological assessments of named individuals.
2. Degrades without visible evidence. When there is limited observable evidence of the system in action, the mapper cannot generate credible hypotheses. It needs clues to work from.
3. Does not surface power dynamics automatically. Some mental models are enforced by people with institutional authority, not just held individually. This distinction matters for action design and must be named explicitly by the teacher.
4. Not suitable as a live classroom exercise without careful facilitation planning. When students are present and could recognise themselves or peers in the mental model map, psychological safety planning is required before use.

Before you deliver: a quick check

• [ ] Mental models are labelled as hypotheses.
• [ ] Each model links to visible evidence.
• [ ] Each model links to structures and patterns.
• [ ] Protective functions are considered.
• [ ] Alternative models include enabling structures.
• [ ] Dialogue prompts are safe enough for classroom or staff use.
