Background on group decision-making

Articles about what goes wrong when a group decides together, and what does work. Written from the practice of Group Concept Mapping.

Why it goes wrong

What happens when a group decides together.

Why the loudest voice decides the outcome

In almost every workshop it is not the best idea that wins, but the one voiced first. What exactly happens there, and what you can do about it.

Why a survey does not measure what is actually there

A questionnaire feels objective, but mostly measures what its author already had in mind. What you miss, and when something else serves you better.

Measuring support: what works and what does not

Agreement in the room says little. What does make support visible, and why division is more useful than consensus.

From workshop to decision: why the output evaporates

The energy of a good session rarely survives the following week. What goes wrong between meeting and decision, and how to fix it.

Setting up a project

Choices you make up front that shape the outcome.

What makes a good focus prompt, and why it decides everything

The question you start with sets the limits of what can come out. One word of difference produces either unusable or genuinely sharp themes.

How many participants do you need for a reliable picture

Fewer than you would think, and the number matters less than the spread. What the figures say about group size.

Setting priorities with a team: importance against feasibility

Two axes instead of one show where to start, and why the easiest topic is seldom the right one.

Reading the results

What the figures and the map do and do not tell you.

What bridging tells you that an average conceals

Some statements sit firmly within one theme, others float between them. That floating is not noise but a finding.

Making differences between groups visible

Teachers and administrators rarely look at the same problem the same way. Measuring that difference is more useful than smoothing it over.

From map to scenario: what happens if you push somewhere

A map shows what is at play. A causal model shows what carries through when you intervene in one place.

Method and research

Accountability, and where the method comes from.

Concept mapping in research: from needs analysis to design

The method is not only a workshop format but a recognised research method. Where it fits in a research design.

AI in group research: what to use it for and what not

Language models can take a lot of work off your hands, but not the step that matters. Where the line runs.
