For more than a century, psychology’s disciplinary ideology has remained unchanged. It is a positivist ethos which, despite the failure of positivism as a philosophy of science, continues to sustain psychology’s defective concepts of method and evidence, the false scientific claims that those concepts sanction, misguided research questions and interpretations of results, and, most importantly, an inadequate system of self-correction. Attempts at redress still fall on deaf ears. An ingrained not-wanting-to-know is all too evident. This is unethical and contrary to the disinterested truth-seeking which is a hallmark of genuine inquiry. There are solutions and I suggest some remedial action that could advance psychology’s integrity and scientific maturity.
