Consensusfoot

Consensusfoot is a quantitative concept used to assess and guide consensus in collaborative decision-making. It describes a metric that combines the degree of agreement within a group and the dispersion of individual positions to yield a single score indicating how strongly a proposal enjoys broad and coherent support. The term blends “consensus” with “footprint,” signaling both agreement and the spread of positions that underlie that agreement.

Mechanism: In a typical application, participants express their stance on a proposal along a multi-point scale or through ranked choices. Consensusfoot aggregates these responses into a score between 0 and 1. A high value arises when most participants converge on a similar position with little opposing dispersion; a low value arises when opinions are scattered or polarized. The method often includes two components: an agreement component that rewards clustering of positions and a footprint component that penalizes outliers and fragmentation. Weights can be adjusted to emphasize inclusivity or decisiveness.

Origin and usage: The concept was proposed in deliberative decision-making research to provide a transparent, numeric summary of group sentiment. It has been applied in governance workshops, online deliberation platforms, and organizational decision processes to flag when consensus is achieving and when further discussion is warranted.

Limitations: As with any metric, consensusfoot may oversimplify complex moral or strategic considerations. It can be sensitive to scale choice and sampling, and may undervalue minority but important viewpoints if used as a replacement for qualitative dialogue.
