Historical model

A model of its time

  1. 1977

    Exo Psychology

    Eight circuits. Twenty four stages.

  2. 1987 / 1988

    Info Psychology

    Revision, copyright, and later catalogued editions.

Timothy Leary spent much of the 1970s trying to build an account of consciousness spacious enough to include experiences that conventional personality and clinical psychology often treated separately. Exo-Psychology, published in 1977, organized that account into eight circuits and twenty four stages. Info-Psychology later revised the model, with a 1987 copyright and editions catalogued in 1988. The discussion here follows the circuit and stage structure in the 1977 primary text; the shorter names in the explorer provide a readable route into it. (Leary, 1977) (Leary, 1988)

The stages and the extraordinary claims

Across the model, Leary described a recurring progression from receptivity, through the organization or intelligent use of experience, toward linkage, fusion, or synergy. His actual stage names vary: the fourth circuit moves through sociosexual receptivity, domesticity, and collectivity. The first four circuits concern survival, movement, emotional hierarchy, symbolic thought, sexuality, family, and culture. The later four turn toward bodily consciousness, awareness of mental programming, genetic and evolutionary consciousness, and what he called metaphysiological or neuroatomic consciousness.

Leary intended much more than a metaphor. He attached the circuits to an evolutionary account of nervous system development and, especially in the later circuits, proposed biological and physical mechanisms. His theory includes telepathy, direct communication with DNA, conscious manipulation of genetic information, communication among genetic intelligences, atomic signal reception, and consciousness on a cosmological scale. Those claims belong in an accurate account of the historical model. They have no established standing as explanations of psychedelic experience in contemporary neuroscience or genetics.

Practice application

How this resource uses the model

A practitioner can approach the model through a different question: what dimensions of a person’s life are entering the session? Someone may begin with fear about bodily safety, move into conflict over control, encounter family memories, experience unfamiliar bodily sensations, reconsider an identity held for decades, and then describe contact with ancestors or an experience of universal consciousness. Several of these domains may be present together. Their sequence need not resemble Leary’s developmental order, and no participant needs to progress through all eight.

The Eight Circuit Lens follows these domains into the responsibilities already described by the Global Competencies. The 13 Functions and 50 criteria remain the professional framework. The links offered here are editorial connections for teaching and reflection. Their purpose is to guide reading across the existing manual. The historical account, contemporary literature, and practice examples each have their own role.

Reading the lens

Five kinds of claim

Historical model
An idea from Leary’s original framework. Historical inclusion does not indicate contemporary endorsement.
Contemporary evidence
Modern research independently informs the phenomenon or concern. It does not automatically validate Leary’s proposed mechanism; study type and limits still matter.
Practice application
A connection to a practitioner responsibility, such as preparation, support, assessment, integration, referral, or documentation.
Phenomenology
What a participant reports experiencing. An accurate account can leave the ultimate external cause unresolved.
Speculative claim
An explanation without adequate empirical support. Historical importance or personal meaning does not change that evidentiary status.

Eight chapters · One interpretive lens

Circuit Atlas

Enter through the domain you want to examine. The chapters can be read in any order.

  1. A seated figure rests in a sheltered doorway beside water, looking toward a quiet landscape.
    I

    Bio Survival

    Safety, Regulation, and Basic Trust

    Bodily security and the conditions that make a setting understandable.

    Enter Circuit I
  2. Three figures navigate different courtyard levels and paths, suggesting agency and interpersonal distance.
    II

    Emotional Territorial

    Agency, Power, and Emotional Regulation

    Movement, choice, and the power held by the person managing the room.

    Enter Circuit II
  3. Hands arrange blank paper slips and wooden blocks on a scholar’s table.
    III

    Symbolic

    Language, Cognition, and Meaning

    How language and felt certainty organize an experience into an explanation.

    Enter Circuit III
  4. Several generations gather around a table in a domestic interior.
    IV

    Sociosexual

    Identity, Intimacy, and Social Roles

    The relationships and cultural expectations through which identity takes shape.

    Enter Circuit IV
  5. A seated figure rests a hand over the ribs beside a sunlit window.
    V

    Neurosomatic

    Embodiment and Interoception

    Attention to the body, its sensations, and the meanings attached to them.

    Enter Circuit V
  6. An observer considers open wooden frames that crop the same landscape.
    VI

    Neuroelectric

    Metacognition and Cognitive Flexibility

    The possibility of observing a familiar mental pattern from another perspective.

    Enter Circuit VI
  7. Three generations walk an old path, with earlier figures receding into the landscape.
    VII

    Neurogenetic

    Lineage, Inheritance, and Deep Time

    Lineage and deep time, with a clear boundary between experience and biological claims.

    Enter Circuit VII
  8. A small coastal figure faces a vast, softly merging sea and sky.
    VIII

    Neuroatomic

    Mystical, Existential, and Ontological Experience

    Experiences that alter the sense of self, reality, spirituality, or death.

    Enter Circuit VIII

Contemporary evidence

Meaning, certainty, and practice

Meaning and certainty also deserve attention. A psychedelic experience can feel revelatory even when its explanation remains unsettled. Research and theoretical work on belief change, suggestion, expectancy, and false insight give practitioners reasons to ask how an interpretation formed and what evidence could support it. These are questions about the quality of care, including the practitioner’s own influence, and they can be asked without treating a participant’s experience dismissively. (McGovern et al., 2022) (McGovern et al., 2024) (Borkel et al., 2025)

The Synthesis brings the domains together through integration, practitioner influence, and a critical appraisal of the historical model.
