Fig 3. The growth of an edge’s score due only to consistency (left) and due to convergence (right).

These plots show how the score of a research-map edge increases with each subsequent experiment (all with agreeing results), due to the principle of consistency (left) and due to the principle of convergence (right). The plot on the left represents repeated iterations of the same class of experiment (e.g., Positive Intervention) with consistent results. The plot on the right represents multiple iterations of experiments in which, at each iteration, one of the least-represented classes of experiments was performed, leading to consistent results. These two plots express an axiom of research maps: the principle of convergence carries greater epistemological weight than the principle of consistency.
