The Original Model
The second circuit concerns a body that can move, approach, avoid, occupy space, and act on its environment. Leary connected locomotion and muscular action with territory, hierarchy, dominance, submission, and the effort to avoid helplessness. He believed that early patterns of successful or unsuccessful action contributed to an interpersonal emotional style, including habitual ways of asserting oneself or yielding to others. His stages describe neuromuscular receptivity, intelligence, and fusion-synergy. (Leary, 1977)
The historical account places these patterns inside a proposed evolutionary sequence. Contemporary practice can examine agency, emotional regulation, and interpersonal power without accepting that sequence or sorting people into fixed dominant and submissive types. A person’s response to authority may change with the relationship, the setting, and their current state.
Contemporary Translation
A participant may voluntarily enter a controlled setting and then take a substance that changes perception, judgment, coordination, emotional regulation, social interpretation, and the sense of time. The practitioner remains able to manage the room, music, timing, movement, access to other people, touch, and emergency decisions. They may also become the person whose explanations seem most credible. That combination gives ordinary choices about care unusual weight. Contemporary ethics guidance places autonomy, clear boundaries, and accountability at the center of this relationship. (Jacobs et al., 2024) (McGuire et al., 2024)
Preparation should clarify authority while the participant can consider it carefully. Which safety boundaries are fixed? Which practices are optional? What happens if a preference changes, the participant wants to stand, or they ask to leave? What can prior consent authorize, and how will current assent or refusal be recognized? Explain the limits of touch, the circumstances requiring emergency intervention, and how concerns can be reported outside the immediate relationship. Earlier agreement to participate does not create unlimited permission for everything a practitioner later considers helpful. (Bradberry et al., 2024) (McHerron et al., 2025)
Previous experiences with authority can enter the room through medical trauma, coercive treatment, incarceration, military systems, family violence, abusive relationships, or other institutional encounters. These histories do not predict a single response. One person may become watchful and assertive, another deferential, and another alternate between the two. Assessment should follow the person’s actual communication rather than a story about what someone with that history ought to do.
Power also operates quietly. Compliance can coexist with discomfort, silence can reflect uncertainty, and movement may be an attempt to regulate discomfort rather than avoid psychological work. Language such as “the medicine wants you to stay with this” can turn a practitioner’s preference into an apparently external instruction. Calling disagreement “resistance” or “your ego fighting the process” can make it harder to refuse. A collaborative alliance leaves room for correction, including correction of the practitioner. The alliance literature supports studying that relationship while acknowledging that psychedelic therapy research on it remains limited. (Kamilar-Britt et al., 2023)
Consent across the relationship
Before
Clarify fixed boundaries, optional practices, and how preferences can change.
During
Attend to present communication, assent, refusal, and uncertainty.
After
Return decisions to the participant; trust does not confer authority over their life.

In Practice
A participant repeatedly asks to stand or leave the room. The practitioner first tries to understand the request: pain, toileting, fear, temperature, restlessness, or a need for distance may be involved. They explain any immediate safety concern and work toward the least restrictive safe option available under the agreed plan. They do not make remaining still a test of psychological commitment.
A participant previously agreed to supportive hand holding but is no longer clearly responsive when it is offered. That uncertainty should not be treated as renewed permission. Pause optional touch, check communication and responsiveness, and follow the consent plan. Emergency assistance has a different justification and must remain proportionate to the actual need. Qualitative research with psychedelic trial researchers describes precisely these difficulties around changing preferences and expanding consent during dosing. (McHerron et al., 2025)
After a session, a participant becomes highly deferential and asks the practitioner whether to leave a partner, change jobs, or move away. The practitioner explores what the person values, helps identify information and appropriate consultation, and returns the decision to them. Interpretive authority can outlast intoxication. Gratitude and trust do not authorize the practitioner to direct a person’s life.
Evidence Boundary
The ethics consensus statements, informed consent literature, touch research, and work on therapeutic alliance address real professional responsibilities. Consensus recommendations and qualitative findings have different evidentiary roles from controlled efficacy studies. They support attention to power and autonomy without demonstrating Leary’s second neurological circuit or a fixed developmental origin for anyone’s interpersonal style.
