These answers draw in part from “Humility: The Ninth Dimension of Behavior Analysis” by Shane Spiker, Ph.D., BCBA (BehaviorLive), and extend it with peer-reviewed research from our library of 27,900+ ABA research articles. Clinical framing, BACB ethics code references, and cross-links below are synthesized by Behaviorist Book Club.
View the original presentation →The original seven dimensions are applied, behavioral, analytic, technological, conceptually systematic, effective, and generality. Applied means the research addresses problems that are socially significant. Behavioral means the focus is on observable, measurable behavior. Analytic means there is a convincing demonstration that the intervention is responsible for the behavior change. Technological means the procedures are described in sufficient detail to allow replication. Conceptually systematic means the procedures are related to basic behavioral principles. Effective means the behavior change is clinically significant, not just statistically significant. Generality means the behavior change occurs across settings, behaviors, and time. These dimensions have guided the field for over fifty years and continue to serve as the foundation for evaluating behavior analytic work.
Compassion and humility are complementary but distinct orientations. Compassion, as proposed by Penney and colleagues (2023), focuses on the practitioner's orientation toward the suffering and wellbeing of others, emphasizing actions that alleviate suffering and promote flourishing. Humility focuses on the practitioner's orientation toward their own knowledge and its limitations, emphasizing openness to learning, acknowledgment of uncertainty, and willingness to revise assumptions. Compassion asks how do I respond to others' experiences, while humility asks how do I relate to my own expertise and its boundaries. Together, these dimensions address the relational and epistemic aspects of practice that the original seven dimensions, focused primarily on methodology and outcomes, did not explicitly address. A practitioner can be compassionate without being humble, and vice versa, but the most effective practice integrates both.
Humility can be operationally defined as a repertoire of observable behaviors that reflect awareness of the limitations of one's knowledge and openness to learning from others. Specific measurable behaviors include frequency of asking questions versus making statements during clinical discussions, percentage of treatment plans that incorporate documented family input, rate of alternative hypothesis consideration during functional assessments, frequency of seeking peer consultation or supervision, latency to modify treatment approaches when data indicate insufficient progress, and proportion of interprofessional communications that include acknowledgment of other disciplines' expertise. While internal experiences of humility are private events, the behavioral manifestations are observable and measurable using the same methods behavior analysts apply to any other behavioral repertoire.
Professional humility and self-doubt are functionally distinct. Self-doubt involves uncertainty about one's ability to perform professional tasks competently and is associated with avoidance, hesitation, and reduced professional engagement. Humility involves accurate recognition of the limits of one's knowledge alongside confidence in the knowledge one does possess. A humble behavior analyst is not paralyzed by uncertainty but rather makes confident decisions while remaining open to new information that might warrant revision. Humility is compatible with strong clinical skills, clear clinical reasoning, and decisive action. What it adds is the ongoing willingness to question one's assumptions, seek feedback, and revise one's approach based on new evidence or perspectives. The humble practitioner says I am confident in this recommendation and I remain open to learning that a different approach might be better.
Organizations can create humility-supportive cultures through several structural practices. Leadership should model humility by openly discussing their own learning edges, acknowledging organizational mistakes, and demonstrating receptivity to feedback from all levels of staff. Peer review and consultation should be built into clinical processes as routine practices rather than exceptional ones. Staff meetings should include dedicated time for discussing clinical uncertainties, alternative hypotheses, and lessons learned from unexpected outcomes. Performance evaluations should include measures of collaborative practice, receptivity to feedback, and willingness to modify approaches based on data. Organizations should create psychological safety by responding to acknowledged mistakes with support and learning rather than punishment. Supervision structures should encourage supervisees to express disagreement and offer alternative perspectives. These structural practices reinforce humble behavior across the organization.
Humility and evidence-based practice are deeply interconnected. Genuine evidence-based practice requires humility because it demands the willingness to change one's approach when evidence indicates that current methods are insufficient. A practitioner without humility may selectively attend to evidence that confirms their preferred approach while dismissing evidence that challenges it, which is confirmation bias rather than evidence-based practice. Humility also requires acknowledging the limitations of the current evidence base, including the populations studied, the conditions under which studies were conducted, and the outcomes that were measured. A humble approach to the evidence base treats published research as the best available guidance while recognizing that the evidence is always evolving and that clinical judgment must bridge the gap between group research findings and individual client needs.
Many criticisms from the autistic self-advocacy community center on perceived arrogance within the field, including assumptions that behavior analysts know what is best for autistic people better than autistic people themselves, that the goal of treatment should be normalization of behavior, and that the field has adequately addressed its historical harms. Humility directly addresses these criticisms by creating an orientation in which behavior analysts listen genuinely to autistic perspectives, acknowledge the field's historical mistakes, question whether traditional treatment goals reflect the values of the people served or the assumptions of the people serving, and remain open to fundamentally revising practices based on feedback from the communities most affected by those practices. This does not mean abandoning evidence-based practice but rather expanding the evidence base to include the lived experiences and preferences of autistic individuals.
In interprofessional settings, humility manifests as genuine respect for the expertise of other disciplines, willingness to defer to other professionals in areas outside the behavior analyst's competence, use of accessible language rather than discipline-specific jargon, asking questions about other professionals' perspectives rather than immediately offering behavioral interpretations, and acknowledging when a client's needs require expertise that the behavior analyst does not possess. Practically, this means saying things like the SLP has more expertise in this area than I do or I had not considered that perspective, thank you for sharing it. These statements are not signs of weakness but of professional maturity. They build trust with interprofessional colleagues, improve collaborative treatment planning, and ultimately benefit clients by ensuring that the full range of professional expertise is brought to bear on their care.
Humility transforms treatment failures from sources of professional embarrassment into opportunities for learning and improvement. When an intervention does not produce the expected outcomes, a humble behavior analyst examines their own clinical reasoning rather than attributing the failure to the client, the family, or the implementer. They ask whether the functional assessment was accurate, whether the intervention was well-matched to the identified function, whether there were implementation variables that were not adequately addressed, and whether the treatment goals were appropriate and meaningful. This self-examination often reveals clinical insights that lead to more effective intervention redesign. Without humility, treatment failures tend to produce defensiveness, blame, and repetition of the same ineffective approach, which delays meaningful progress and erodes trust with families.
Most current BCBA training programs do not explicitly teach humility as a professional competency, though many address related concepts such as cultural humility, collaborative practice, and ethical decision-making. The proposal to add humility as a dimension of behavior analysis suggests that explicit training in humble professional behavior would benefit the field. This training might include instruction in alternative hypothesis generation, practice in seeking and receiving feedback nondefensively, exposure to perspectives from other disciplines and from the communities served by behavior analysis, reflection exercises that help students identify their own assumptions and biases, and modeling by faculty and supervisors who demonstrate humble practice. As the field increasingly recognizes the importance of relational and epistemic dimensions of practice, training programs may incorporate humility more explicitly into their curricula.
