In recent decades, theorical analysis in psychology has been reduced primarily to formulating models that merely explain experimental results. This narrow focus, shaped by a positivist philosophy of science, sidelines broader questions of what is fundamentally true about human nature, behavior, and experience. In their article “Theory as Truth and as Ethics,” published in the Journal of Theoretical and Philosophical Psychology, Richard N. Williams and Edwin E. Gantt (2025) contend that, if psychology wants to be recognized as a genuinely human science, it must restore theory to its deeper function: clarifying what is true about human existence and addressing the moral implications of such claims.
The authors contrast current trends in psychology with earlier traditions. Previously, psychology courses emphasized subjects such as personality theory and the history of ideas; today, however, the field stresses measurement, quantification, experimental design, and construct testing (Alexander & Shelton, 2014; L’Abate, 2013). This shift reflects a skepticism about, or a lack of interest in, the possibility of truth (McIntyre, 2018; Osbeck & Antczak, 2022; Stenmark et al., 2018). Radical skepticism, in a bit of self-contradiction, affirmatively denies the existence of objective truth (Williams, 1999). Psychology has largely embraced skepticism, leaving it unable to make meaningful theoretical claims about human nature. The result is a fragmented discipline that risks sliding into pseudoscience and irrelevance because it is unable to articulate a coherent conception of its subject matter (Lilienfeld, 2010, 2012).
Williams and Gantt argue that truth in psychology should not be equated with mere facts or observed events. Events happen, but truth lies in the meaning we assign to them, how we engage with them, and the meaningful differences they make. Following the philosophers Martin Heidegger and William James, they emphasize truth as a correspondence between lived human experience and our accounts of it (Wilshire, 1977). For James, pragmatism did not mean reducing truth to “what works” in a superficial sense but rather assessing how and whether ideas help us intellectually, practically, and morally to live in accordance with reality (see, e.g., James, 1981, 1988). Thus, truth and morality are inseparable: What is taken to be true matters because it has ethical (i.e., meaningful) consequences.
The authors stress that human life is inherently moral. Every meaningful difference we encounter in experience matters to us as good or bad, desirable or harmful. This inevitability of moral evaluation shows that morality cannot be postponed until truth questions are settled. Instead, the two are intertwined. To deny moral evaluation is to drift into nihilism. Accordingly, theories in psychology are never neutral. They always have ethical implications because they shape how professionals act and how people understand and are understood.
This article highlights the responsibility of theory to engage truthfully and ethically with human life. Far from being oppressive, truth claims and moral commitments are necessary to avoid the “tyranny of opinion” and the emptiness of relativism. Ultimately, the authors argue, theory must be restored to its proper role: illuminating the moral texture of human existence, guiding both research and practice toward meaningful engagement with what is real.
Their analysis suggests that psychologists must integrate questions of truth and ethics into their research programs. It challenges professionals to recognize the moral weight of their models and methods. Beyond psychology, their argument reminds us that disciplines claiming to study human life must grapple with meaning, value, and responsibility. Without this, they risk irrelevance and, ultimately, offer only nihilism.
