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.

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.

Density is widely considered a fundamental characteristic of cities, shaping and defining urban life. A recent seam of geographic research has sought to critically theorise density, arguing that it should be considered as more than a numerical descriptor, and instead as historically situated, politically produced and affectively experienced. But this literature is anthropocentric in its concerns, neglecting that most wild animals in cities also have high population densities. For many animals, living at high density is a similarly ubiquitous and foundational quality of urban life. This paper asks how urban animal density is produced, spatialised and generative of particular forms of sociality. It does so by investigating the lives of a group of red foxes living on an allotment in North East London. It makes three interlinked arguments. First, that urban animal density is produced through historically contingent and politically provisional socioecological patches. Second, that the ecological affordances of these patches are generative of novel forms of sociality amongst foxes themselves, which challenge conventional readings of fox social organisation. Third, that the geographies of urban density create routinised encounters between people and foxes through which emerge vernacular knowledges of each other as individual subjects. In doing so, it seeks to ecologise urban geography's understanding of density as a city-making process, and to understand animal density as a way in which the urban itself unfolds. The paper is drawn from in-depth ethological-ethnographic fieldwork, where I worked with local people to chart the everyday practices and socialities of red fox groups, and sought to amplify and affirm localised ecological knowledge.
To investigate how urban animal density is produced, spatialized, and generative of particular forms of sociality, using red foxes as a case, and to extend critical theorizations of density beyond an anthropocentric focus.
A group of red foxes living on an allotment site in North East London, studied together with local residents.
In-depth ethological-ethnographic fieldwork combining animal-behavior observation with ethnographic methods, tracking everyday fox practices and human-fox encounters over time.
High-density urban living was found to generate socioecological patches that produce novel forms of fox sociality departing from conventional accounts of fox social organization, and routinized human-fox encounters were found to generate mutual, vernacular 'knowledges' of each other as individual subjects.
The paper treats density as a whole-level condition that generates novel social forms among the individuals living within it, and shows that humans and foxes come to hold perspectives on each other as density-driven encounters recur.
