The very existence of truth, let alone its worth, is currently under attack from many quarters. In the wider culture, disinformation and other forms of misrepresenting the truth spread far and wide, as information conduits proliferate. This paper suggests some reasons for the “anti-truth” trend. Mainstream media have played a role, as have theoreticians from fields as diverse as philosophy, psychoanalysis, science, and literary criticism. “Anti-truth” trends are having a serious impact on psychological treatment, affecting its content and the conception of its goals. This paper suggests some problematic outcomes of this phenomenon for practitioners and patients in various forms of psychotherapy.
