Ideological bias is a worsening but often neglected concern for social and psychological sciences, affecting a range of professional activities and relationships, from self-reported willingness to discriminate to the promotion of ideologically saturated and scientifically questionable research constructs. Though clinical psychologists co-produce and apply social psychological research, little is known about its impact on the profession of clinical psychology. Following a brief review of relevant topics, such as “concept creep” and the significance of the psychotherapeutic relationship, the relevance of ideological bias to clinical psychology, counterarguments and a rebuttal, clinical applications, and potential solutions are presented. For providing empathic and multiculturally competent clinical services, in accordance with professional ethics, psychologists would benefit from treating ideological diversity as another professionally recognized diversity area.
