Remarkably, business textbooks love two-dimensional diagrams, which allow to define a domain with the minimal number of separable dimensions.
Exercise for the reader: place Putin and Trump on the diagram, wrt the former's war with Ukraine and the latter's war with Iran. Explain.
Conversely, trade-offs allow to collapse a domain into one dimension.
The central notion of conceptual space is defined as a collection of
one or more domains with a distance function (a metric) that represents
properties, concepts, and their similarity relations.
