Evidence and research

What the research says.

Two kinds of evidence sit behind TetraMap—research into TetraMap itself, and independent research into the principles it’s built on.

Our evidence

Research on TetraMap itself.

01 | Peer-review study

Hong Kong Polytechnic University.

A peer-reviewed study at the College of Professional and Continuing Education, Hong Kong Polytechnic University, examined 126 students working in groups and found that group breakdowns — a dominant member steamrolling the group, unclear ownership of tasks, teams going quiet rather than working through disagreement — mapped closely onto TetraMap’s four Elements. The researchers concluded that introducing TetraMap before group work begins gives students a shared, non-judgemental language for exactly the tensions that usually derail collaboration.

02 | Adaptation of TetraMap

Te Wānanga o Aotearoa.

Separately, Te Wānanga o Aotearoa — the largest indigenous tertiary institution in the world — has spent years adapting TetraMap alongside Te Tapa Toru, an indigenous model of understanding people, reportedly the first time a tertiary provider has held that kind of arrangement directly with TetraMap’s founders. It’s not a peer-reviewed study, but it’s a substantial, documented example of the framework being tested and reshaped by a serious institution rather than simply adopted as-is.

A note on validity:

TetraMap is a metaphorical, experiential learning model, tool, framework and approach. Its strength is face validity. It makes intuitive sense to the people using it, and that intuitive fit is a large part of why it sticks. It is not a psychometrically normed instrument with reliability scores and population norms, and we don’t present it as one. That’s a deliberate choice: it keeps the model plain and usable rather than adding statistical machinery that would make it harder to pick up in a single workshop.

Our research

Independent research that supports our thinking.

These five studies were not conducted on TetraMap, and none of them mention it. What they show is that the ideas behind our five beliefs are consistent with what leading, independent researchers find elsewhere—not just what we say about our own method.
