Taxonomies are fun and usually treeshaped. Trees are “easy” to visualize. When people have a taxonomy they often like to visualize them.
But the results aren’t always so nice. Given that this is a taxonomies of fallacies, I found their misuse of a visualization highly amusing. It is also reminiscent of one of my thesis topics (non logical reductios).
mc et al called this the pathetic fallacy (of RDF).
