Within this context, this article attempts to extend the work on how biases can affect medical assessment and decision making in the practice of psychotherapy. We illustrate how cognitive and affective biases may adversely affect the conduct of psychotherapy, describe strategies to mitigate these influences, and call for systematic research in this area.
Results
We initially selected 17 cognitive and affective biases from the medical literature for consideration. Four of these were similar enough to be combined, reducing our final set to 13, as detailed in the case presentations below and in
Table 1. The first case presented below, in which one of the authors (J.Y.) was involved as a colleague, is based on a prior publication (
31). The other examples are composites based on clinical elements from our collected experiences rather than on individual cases. The vignettes demonstrate how each type of bias can alter the moment-to-moment conduct of psychotherapy sessions and shape the course of the psychotherapy over time. The biases we enumerate below provide an illustrative, not exhaustive, list.
Availability Bias: Vignette
The availability bias (closely related to “recency bias”) is the tendency to judge things as more likely if they readily come to mind. An excellent example of the availability bias has been provided by Gitlin (
31), in describing his reactions to the suicide of a patient. For months after one of his psychotherapy patients committed suicide, Dr. Gitlin became preoccupied with thoughts that many of his patients might be suicidal. Subsequently, whenever patients remarked about feeling depressed, Dr. Gitlin would interrogate them about whether they were having suicidal fantasies, often with little basis to substantiate his impression. As detailed in his report, at one point a patient eventually became so exasperated with Dr. Gitlin’s persistent questions about overdosing—which she had never done or even threatened to do—that she told him, “Look, I can’t promise that I won’t kill myself, but I promise that if I do it, it won’t be with your pills. So, leave me alone already!’”
Dr. Gitlin’s visceral reactions, emotional arousal, and increased vigilance concerning suicide contributed to his heightened tendency to widely seek, and possibly see, signs of suicidality in all his patients, more so than was usual in his previous practice. After his patient’s admonition, Dr. Gitlin handled this threat of therapeutic rupture by acknowledging to the patient that he had become overly sensitive about suicide because of his recent experience. The patient’s blunt feedback also allowed him to continue to treat her successfully and helped him become aware of his bias. Dr. Gitlin also sought additional feedback from a mentor and, with his own psychotherapist, engaged in additional reflection about his reactions. He realized that his heighted attention to risks of suicide among his patients was associated with concern about his mentor’s opinion of him and his own doubts about his professional competence.
Framing Bias: Vignette
Framing bias (closely related to the “context error bias”) explains that the ways we perceive a problem may be strongly influenced by the way in which the problem is initially framed (e.g., on the basis of the patient’s previous diagnoses). One of the authors (J.K.) began treating a prominent corporate executive because the executive’s wife, convinced of his infidelity, demanded that he seek counseling. The patient was intelligent, confident, and eloquent. From the beginning of the first visit, he adamantly and repeatedly maintained his innocence and provided multiple examples of his wife’s instability. Although the psychiatrist empathically posed multiple questions about behaviors that may have been construed as unfaithful, the patient convincingly described that he agreed to these sessions to humor his wife, who was misguided, if not delusional. After the third session, the patient stated that, in fact, nothing in his life supported his wife’s claims, and he was ending treatment. The clinician tended to agree with the patient, and no further visits were scheduled. Two weeks later, the wife called, desperately requesting to meet with the psychiatrist, who agreed to see her. Although depressed and anxious about her failing marriage, she was not seeking treatment but was planning to move away after finding her husband at their home in bed with his secretary. The wife explained that she wanted validation and confirmation from the psychiatrist that her behavior was not disturbed.
After this meeting, the psychiatrist recognized that he had been gullible and taken in by the patient. On reflection, he realized that from the first contact, the patient’s status, reputation, and convincing portrayal of his wife’s psychological instability had biased the psychiatrist’s subsequent thinking, leading him to assume that the patient was telling the truth.
Sunk Costs Bias: Vignette
The sunk costs bias is the tendency, after making considerable investment, to continue putting effort and resources into ventures that appear increasingly unlikely to succeed (i.e., the unwillingness to let go of a failing strategy). For clinicians, these investments include time and energy. This bias was originally associated with financial investments.
Dr. A., a psychiatric resident, described a 15-year-old girl he had been treating for 6 months in weekly psychotherapy as anxious, rigid, and selfish. After initiating psychotherapy in one setting, they continued working together after his transfer to another clinic and supervisor. Dr. A. reported that his previous supervisor felt that he needed more time with this patient to make headway, especially because he was seeing her only weekly. Dr. A. had spent many sessions attempting to build an alliance and understand his patient, exploring her interests, playing board games, and discussing her immersion in video games. Although Dr. A. felt he knew a lot about her interests, he could not describe much about her inner life. Her parents were willing to have her continue therapy, pleased that their daughter was less resistant to this therapy than to previous therapeutic attempts. Although the patient’s anxiety remained high and she still avoided school, her parents felt the investment of time would start to pay off.
The new supervisor asked to review some video-recorded sessions and noted that the patient had many features suggestive of autism. He wondered whether the difficulties Dr. A. and the previous supervisor had experienced in questioning the patient’s lack of therapeutic response were partly related to the sunk costs bias.
Discussion
On the basis, primarily, of the work of Croskerry and his colleagues in general medicine (
21–
26), we have illustrated how cognitive and affective biases related to heuristic mental shortcuts initially studied by Kahneman and Tversky (
13,
14) may have an impact on the conduct of psychotherapy. Personal skews and biases may intrude and shape clinicians’ attentional foci during every session and in turn may account for significant differences in the moment-to-moment interactions initiated by psychotherapists. In addition to the biases noted above, others may be added to this list as well. For example, a “self-serving” bias may apply to the conduct of psychotherapy, affecting decision making related to a range of competing interests, including the clinician’s intellect, face-saving, longing for intimacy, and financial considerations (
32). Hindsight biases may lead to “I-told-you-so” moments, in which clinicians selectively recall prior remarks that seemed to predict an outcome, conveniently neglecting those that may have communicated contrary messaging (
33,
34).
By distorting judgments, cognitive and affective biases can impair the development of successful therapist-patient relationships from the outset of treatment and can contribute to risks of making patients feel misunderstood and to ruptures in the therapeutic alliance during treatment. Therapist anxiety may increase tendencies to fall back on fast thinking and susceptibility to specific biases (e.g., the anchoring bias may result in distorted imprinting on unimportant or distracting issues). Cognitive and affective biases can contribute to therapist gullibility in cases where therapists might unquestioningly believe patient’s distortions or lies, for example about marital fidelity or substance misuse. Biases may distort and preempt how a therapist hears the patient’s affect and concerns, leading to failure in authentic attunement with the patient.
Omission bias bears specific mention in relation to psychodynamic psychotherapy. Acts of omission by the therapist may be erroneously justified by misinterpretations of the classical psychoanalytic psychotherapist’s role, where the therapist remains silent and passive in order to offer a blank screen onto which patients project feelings, fantasies, and wishes. Justifying omissions to foster the emergence of transference neurosis is a common problem among novice psychodynamic therapists.
Overconfidence bias may reflect narcissistic blindness or overcompensation for self-doubt in the psychotherapeutic role. It may be easier to dazzle patients with “brilliant” interventions than to struggle with the difficulties of tolerating ambiguity and engaging in the self-questioning so necessary for effective clinical work.
Premature closure bias (and the closely related “vertical line failure biases”) have been noted in relation to many types of psychotherapy. Clinicians affected by this bias may be close minded, sometimes because of allegiance to narrow theoretical models, which blind them to other ways of thinking. Procrustean approaches, in which observations about patients are distorted to fit the theory, may result when therapists lack attunement to the bigger clinical picture. By avoiding narrow-minded thinking, clinicians who are adaptive experts assume broad-based understandings of their patients’ problems and are open to examining all models, in contrast to experts who rely primarily on their own familiar, well-practiced routines (
35). Notably, additional clinical experience alone does not guarantee that clinicians will be more immune to cognitive biases, such as premature closure (
36).
Visceral biases lie at the core of countertransference reactions in any type of treatment situation. Problems are more likely to occur when clinicians immediately act on their visceral reactions rather than reflecting on what these reactions are signaling. When therapists viscerally respond to patients by experiencing telltale signs such as boredom, sleepiness, irritation, erotic feelings, repugnance, anger, overhelpfulness, strong idealization, or feeling threatened, for example, these signals can pave the way toward greater accuracy in treatment by pulling therapists deeper into patients’ inner worlds. Exploring whether such signals may also be experienced by others with whom patients interact outside therapeutic settings can enrich therapists’ understanding of their patients. By carefully acknowledging and selectively sharing their own feelings, therapists’ may help some patients to better identify and deal with feelings that the patients have difficulty tolerating.
In some of the clinical examples provided in this article, therapeutic stalemates or near ruptures occurred when therapists failed to see or acknowledge their own roles in the difficulty, at least initially. Almost all such ruptures can be addressed, but only if clinicians are open to acknowledging their contributions and are willing to confront them. As illustrated, other biases result in failures to perform adequate initial assessments, for example failure to fully inquire about biological and social factors and to accurately understand key events precipitating the patient’s application for treatment, all of which may highlight underlying core issues.
Attempts to align cognitive and affective biases with customary views of countertransference are complicated by the lack of clear and widely accepted definitions for these terms and by the fact that studies concerning biases and countertransference have been developed through different intellectual traditions, virtually in separate silos. Whereas the broadest definitions of countertransference may subsume cognitive and affective biases, Croskerry et al. (
23) have considered countertransference, emotional biases, and fundamental attribution errors to be separate sources of emotional influence on clinical performance. Factors contributing to clinician biases may include hardwiring (genetics, temperament), regulation by emotions, overlearning (repetitive exposure), implicit learning, and deliberate but erroneous use of biases that have become established through previous inferior decision making (
37). Each of these processes is also likely to contribute vulnerabilities to broadly defined countertransference.
How might adverse effects of clinicians’ cognitive and affective biases on the conduct of psychotherapy be alleviated? Because these biases are deeply entrenched, mitigation is difficult and unlikely to occur easily or to be sustained with single applications of one-size-fits-all techniques (
26). A systematic review (
38) identified 60 mitigation strategies, the majority of which were shown to be at least partially successful. These debiasing strategies have used combinations of cognitive, technological, affective, and motivational approaches. Cognitive approaches have aimed to increase individuals’ awareness and critical thinking, technological approaches have used graphs and statistics to inform individuals about problems concerning base-rate neglect or framing biases, affective approaches have focused on or induced feelings associated with biases, and motivational approaches have attempted to hold individuals accountable for the results of their biases (
38). Overall, in the context of solving real-world problems, case-based learning appears to be more effective than simple presentation of abstract rules (
39,
40).
Several techniques developed for general medical settings may be applicable for psychotherapy. Among the suggested cognitive bias mitigating approaches are debiasing approaches, such as being more skeptical, affective debiasing, metacognition, mindfulness and reflection, slowing down strategies, rebiasing, personal accountability, educating intuition, and cultural training (
41–
43); detailed instruction and education concerning cognitive biases (
44); formal feedback (
1); consideration of alternatives; increased attention to certain types of ignored data (Bayesian thinking) (
45,
46); and decreasing reliance on memory (
45). These strategies are consistent with long-standing traditions of psychotherapy education, personal reflection, and supervision. The majority of these strategies are aimed at helping clinicians slow down, reflect, and think deliberately. We recommend the following techniques.
First, we suggest psychological immunization that is based on educating psychotherapists about the existence of these biases early during their training so that they may be aware of the dangers when initially forming professional identities as psychotherapists. All psychotherapy training programs, regardless of theoretical orientation, can review these biases and their potential impact at the beginning and can address them repeatedly throughout training. Learning to detect and minimize the adverse effects of countertransference, including biases, is a key element of psychotherapists’ professionalization and is essential for establishing safe, empathic, and nonjudgmental environments. Because cognitive and affective biases occur more often when therapists’ cognitive resources are stressed or limited, clinicians should be educated about cognitive resources or load and should monitor their own sleep, physical health, stress levels, and time pressures as well as their strong emotions, throughout their careers (
23).
Second, psychotherapists can practice several techniques for metacognitive reflection, reviewing how they conduct psychotherapy by recollecting, writing, and reflecting on session-by-session progress notes and by reviewing audio and video recordings of psychotherapy sessions.
Third, at all career stages, psychotherapists can benefit from individual or group supervision, where countertransference-related issues are identified and discussed. Formal feedback can mitigate the influences of bias on therapy (
1). (As in one of the cases presented above, even direct informal feedback from patients can be impactful.) Especially during training, there may be no substitute for seminars led by seasoned teachers using process notes and video recordings, in which trainees present ongoing therapy cases to groups of peers. Interpersonal process recall offers a specific technique for microscopically reviewing psychotherapy processes and may be especially helpful for detecting the intrusion of biases (
47). Especially useful are examinations of complex cases that have warning signs of potential bias, where the case is not proceeding as expected or where the therapeutic alliance is slipping. In accord with the concept of “slow medicine” in internal medicine, which advocates not rushing into new treatments or paths until they are substantiated, the overriding purpose is to help therapists think before they speak or act. To our knowledge, no formal tools or self-assessment measures have yet been developed to assist with efforts to identify cognitive biases in the conduct of psychotherapy, but calls for their development in other health settings have appeared in the literature (
38). Such tools could help supervisors more systematically attend to biases among trainees.
Finally, this preliminary report raises numerous questions for further study. For example, can we develop formal tools, including self-assessment measures, to better identify cognitive biases in the conduct of psychotherapy? How do psychotherapists differ in their propensities for various biases and the frequency with which these occur in their psychotherapies? How do different psychotherapy approaches and techniques vary in their vulnerabilities to psychotherapists’ biases? How do bias differences translate to specific countertransference vulnerabilities, including those related to ethnocentricities and gender biases? What accounts for the variances among all these characteristics? If we can identify these biases during training and supervision, how can mitigating strategies be used to best alter their adverse impacts? Additionally, how do all these factors influence the outcome of psychotherapy?
