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.

Explores a concept of systems.
He explained that while the actual word “system” can have multiple meanings, the most important form of it is as a structural term. It’s important to note that systems are “conceptualized differently by different investigators.” In other words, the structure of a system will be different when looked at from different perspectives.“We certainly distinguish between, and are interested in, different kinds of systems, for example, nervous systems, number systems, and betting systems. The question is, do these distinctions between kinds of systems warrant, or require, parallel distinctions among senses of 'system', each with its correspondingly different concept of a system?” Importantly, Marchal’s definition of a system is: “ S is a system only if S is a set of related elements.”
Marchal is essentially drawing a line between Distinctions and Systems for us. One is able to turn a system into a distinction, and Marchal acknowledges later that systems are also made up of distinctions. herefore, the word ‘system’ implies a set (S) of interconnected (R) components (D). It is important to note that Marchal is implying that the Relationships themselves are also to be counted as components of the system. This article excellently demonstrates the interconnections between the patterns of mind, as in order for one to Systematize, they have to Relate and make Distinctions.
The concept of a system is one of the most powerful and important ideas in science and the real world, and therefore, getting a general concept of systems is a high priority. Marchal, 1975 explored the concept of a system. He explained that while the actual word “system” can have multiple meanings, the most important form of it is as a structural term. It can also be used in the form of an activity one does (i.e., doing something systematically). It’s important to note that systems are “conceptualized differently by different investigators.” In other words, the structure of a system will be different when looked at from different perspectives. Also, Marchal writes, “We certainly distinguish between, and are interested in, different kinds of systems, for example, nervous systems, number systems, and betting systems. The question is, do these distinctions between kinds of systems warrant, or require, parallel distinctions among senses of 'system', each with its correspondingly different concept of a system?”
Marchal is essentially drawing a line between Distinctions and Systems for us. One is able to turn a system into a distinction, and Marchal acknowledges later that systems are also made up of distinctions. “We can distinguish between things if some feature of one is not had by the other. The distinctions that we bother to draw rest on our interests.” Importantly, Marchal’s definition of a system is: “S is a system only if S is a set of related elements.” Therefore, the word ‘system’ implies a set (S) of interconnected (R) components (D). It is important to note that Marchal is implying that the Relationships themselves are also to be counted as components of the system. This article excellently demonstrates the interconnections between the patterns of mind, as in order for one to Systematize, they have to Relate and make Distinctions.
