Most mainstream psychologists consider philosophy irrelevant to their work, but see themselves as realists. Various opposition movements embrace philosophy but reject realism, either completely or partially, despite upholding ideas consistent with a realist philosophy. Many on both sides see the Tower of Babel that constitutes psychology as a sign of healthy diversity, not fragmentation. We argue that relations among the three factors – philosophy, realism and fragmentation – deserve closer scrutiny. With philosophy’s core method of conceptual analysis deprioritized, both mainstream (...) psychology and the opposition fracture into an array of “partial realisms”, falling away from a realism that is thoroughly consistent. These are the source of psychology’s fragmentation. The conceptual neglect and resulting confusions can be seen in psychology’s recent replicability crisis, and in the widespread adoption of a representationalist approach to the mind/brain. We argue that the metatheoretical coherence and methodological maturity required for genuine scientific progress involves a consistent adherence to realism. We spell out what that involves and consider several reasons why this has been so difficult for psychology. (shrink)

In ordinary circumstances, we can assess the worth of evidence well enough without benefit of any theory; but when evidence is especially complex, ambiguous, or emotionally disturbing—as it often is in legal contexts—epistemological theory may be helpful. A legal fact-finder is asked to determine whether the proposition that the defendant is guilty, or is liable, is established to the required degree of proof by the [admissible] evidence presented; i.e., to make an epistemological appraisal. The foundherentist theory developed in Evidence and (...) Inquiry can help us understand what this means; and reveals that degrees of proof cannot be construed as mathematical probabilities: a point illustrated by comparing the advantages of a foundherentist analysis with the disadvantages of probabilistic analyses of the evidence in the Sacco and Vanzetti case (1921), and of the role of the statistical evidence in Collins (1968).
