The Universal & Atomic Elements of Organization
A falsifiable scientific theory proposing that the same irreducible structures organize both thought and reality — from the quantum to the social scale.
O-Theory proposes that four irreducible structures — Distinctions, Systems, Relationships and Perspectives (DSRP) — form the universal grammar of organization. Rather than being merely useful ways of thinking, these structures are hypothesized to be the atomic elements from which every organized phenomenon emerges, whether in cognition, biology, physics, mathematics, society, or the cosmos.
| D | S | R | P |
| Distinctions | Systems | Relationships | Perspectives |
| Identity ↔ Other | Part ↔ Whole | Action ↔ Reaction | Point ↔ View |
| D := (i ↔ o) | S := (p ↔ w) | R := (a ↔ r) | P := (ṗ ↔ v) |
This is a living scientific evidence compendium: an open, continually evolving collection of independent empirical research, formal theory, mathematical proofs, cross-disciplinary analyses, applications, critiques, and proposed falsifications. Every entry is included because it supports, refines, challenges, or attempts to falsify the theory.
Scientific theories are strengthened not only by evidence that confirms their predictions, but also by surviving attempts to falsify them. This compendium brings both together: independent evidence from researchers who were not testing DSRP and proposed counterexamples evaluated against the formal theory.
One counterexample is enough to falsify O-Theory. Until then, the question remains: do the same four structures organize everything from quantum systems to human thought?
Independent convergence is one of the strongest forms of scientific evidence because researchers arrive at the same conclusion while investigating different questions for different reasons.
The number is not the point. Researchers in different fields, studying different questions with different methods, repeatedly arrived at the same structural predictions—almost always without testing DSRP or using its language.
Try a different term or clear the filters.
This compendium began as the peer-reviewed literature review “A Literature Review of the Universal and Atomic Elements of Complex Cognition,” published in the Journal of Systems Thinking with 109 studies. That paper is the peer-reviewed foundation. What you see here is its living, continuously updated version . New studies are checked before they are added, and the collection now holds and keeps growing. Open any card to see what the researchers found, why it bears on DSRP, and where the original review discusses it, the fuller account.
The collection is updated continuously, so the citation carries the date you consulted it rather than a study count — the count changes weekly, and putting it in the reference would make the same collection look like a different work to everyone who cites it. To cite a single claim or study, use its own address: every one has a permanent link.
This is the adversarial half of the compendium. Where the evidence track asks what converges on DSRP, this one asks what would end it: a single organized phenomenon whose structure needs a fifth pattern, a ninth element, or a fifth structural dynamic. It holds written up from candidates across territories, and resolutions — the general answers those cases settle against. Every case is published whether it held or failed, including the ones still open.
Cite this rather than the evidence collection when the point is what survived attack. The two are separate works with separate addresses: one asks what converges on the theory, the other asks what would end it, and a reference to the first does not support a claim about the second. Case and resolution numbers change when the record is revised, so cite a case by its own permanent link rather than by number.
This collection is meant to keep growing. Send us a study, paper, book or critique that bears on DSRP, whether it supports the theory or cuts against it, and we will read it and decide whether it belongs.

The field of systemology does not yet have a standardised terminology; there are multiple glossaries and diverse perspectives even about the meanings of fundamental terms. This situation undermines researchers' and practitioners' ability to communicate clearly both within and outside their own specialist communities. Our perspective is that different vocabularies can in principle be reconciled by seeking more generalised definitions that reduce, in specialised contexts, to the nuanced meaning intended in those contexts. To this end, this paper lays the groundwork for a community effort to develop an 'Ontology of Systemology'. In particular we argue that the standard methods for ontology development can be enhanced by drawing on systems thinking principles, and show via four examples how these can be applied for both domain-specific and upper ontologies. We then use this insight to derive a systemic and systematic framework for selecting and organising the terminology of systemology. The outcome of this paper is therefore twofold: We show the value in applying a systems perspective to ontology development in any discipline, and we provide a starting outline for an Ontology of Systemology. We suggest that both outcomes could help to make systems concepts more accessible to other lines of inquiry.
Argues that systemology's terminological disorder can be repaired by building an Ontology of Systemology, and that standard ontology-development methods are improved by applying systems thinking principles to them. Demonstrates the method on four examples, then derives a framework for organizing the field's terminology.
The authors adopt Cabrera's four operations as their working definition of systems thinking – "Distinction making, Interrelating, Organising Systems, and Perspective taking" – and use them, along with emergence, boundaries, levels, and isomorphic patterns, as the principles that enhance ontology construction. Their central move is that an ontology is itself a conceptual system, so its coherence is an emergent property of the whole rather than a feature of any one definition. Four worked examples: healthy defined through unhealthy; existent defined by examining its antonym, nothing, yielding "an existent is a bearer of properties"; an upper-ontology cascade from existent to Thing, Process, Event, and Relationship, concluding that "fundamental existents are things and concepts, not processes or events"; and the Linnaean hierarchy as a case of inherited aspects clarifying distinctive characteristics at each level. From these they derive a concept map of the upper kinds of existent and a framework separating domain from upper ontologies while keeping boundaries open to neighboring fields, with disciplinary ontologies connected in what they call an ontology ecosystem. They claim two outcomes: that a systems perspective improves ontology development in any discipline, and that they have supplied a starting outline for an Ontology of Systemology.
This is a citing use of DSRP by an independent group in systems philosophy, not a test of it. What makes it worth keeping is where the four operations end up. The authors take them as the definition of systems thinking and then let the work be carried mainly by two of them. Their "dialectical feedback" principle – define a concept by working out its opposite – is identity-other, and they reach it from the dialectical tradition rather than from DSRP; they use it to define health through unhealthy and existent through nothing, which is the Is/Is Not operation performed on the top category of an upper ontology. Their treatment of an ontology as a whole with emergent coherence, of levels ordered by complexity, and of the ontology of genomics as a holon within the ontology of biology is part-whole throughout. Perspective is named in the method and appears as worldview in the keywords, but the four examples do not visibly turn on it, which is the ordinary Pareto shape.
Authors: David Rousseau and Julie Billingham (Centre for Systems Philosophy; Rousseau also ISSS, Centre for Systems Studies at Hull, and the Bertalanffy Center) and Javier Calvo-Amodio (Oregon State, INCOSE). Problem framing: Charles Francois' encyclopedia carries 18 pages of definitions for "system" and nearly four pages for "hierarchy," and "emergence" means different things to systems engineers than to systems scientists. Verbatim on the four operations: "Distinction making: differentiating between a concept's identity (what it is) and the other (what it is not), between what is internal and what is external to the boundaries"; "Interrelating: inter linking one concept to another by identifying reciprocal (i.e., 2 x 2) causes and effects"; "Perspective taking: reorienting a system of concepts by determining the focal point from which observation occurs by attributing to a point in the system a view of the other objects." On dialectical feedback: "The meaning of the initial concept of interest is deepened and clarified by making it contingent on also understanding the concept associated with its opposite." On emergence in ontologies: "the mutual coherence of the definitions makes the system stable as a whole," with the aim that "relationships and interdependencies between the categories are made explicit, easy to trace, and open to assessment." On holons: "the ontology of genomics is a holon within the ontology of biology." They position the work against mature existing practice – ISO standards, BFO, SUMO – as an enhancement rather than a replacement.
An independent group in systems philosophy takes the four operations as their working definition of systems thinking and builds an ontology method on them. What makes it interesting is not the citation but where the weight falls: two of the four carry most of the work, and their dialectical feedback principle is defined in terms that are already relational.
