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.

Understanding and responding to adverse human health impacts of global environmental change will be a major priority of 21st century public health professionals. The emerging field of planetary health aims to face this challenge by studying and promoting policies that protect the health of humans and of the Earth’s natural systems that support them. Public health, drawing on its experience of guiding policies to improve population health, has contributed to planetary health’s development. Yet, few public health practitioners are familiar with planetary health’s systems-oriented approaches for understanding relationships between economic development, environmental degradation, and human health. In this narrative review, we present key planetary health concepts and show how systems thinking has guided its development. We discuss historical approaches to studying impacts of economic development on human health and the environment. We then review novel conceptual frameworks adopted by planetary health scientists to study and forecast impacts of policies that influence human health and Earth’s natural systems at varying spatiotemporal scales. We conclude by presenting examples of how applying the “Doughnut” model (an economic framework where the needs of people are met without overshooting the world’s ecological limits) could guide policies for promoting health co-benefits to humans and natural systems.
This narrative review examined how systems thinking can help public health understand and respond to planetary health problems, especially the interconnected effects of economic development, environmental degradation, and human health. The authors reviewed systems-oriented frameworks and policy examples involving food systems, urbanization, environmental change, and the health of both people and natural systems.
The authors argue that systems thinking is essential for understanding complex causal pathways, feedback, multilevel systems, and unintended consequences. They show that considering systems and multiple perspectives can reveal policy effects that reductionist approaches may miss and can help identify policies that produce co-benefits for human health and natural systems.
Adopts Cabrera & Cabrera's DSRP structure (distinctions, part-whole systems, causal relationships, perspectives) as the organizing vocabulary for how public health should reason about planetary health. The paper explicitly defines systems thinking through the four DSRP patterns and applies that framework to public-health and planetary-health problems. It also reviews empirical and modeling evidence showing benefits from systems-oriented policies.
This paper is a narrative review rather than a controlled experiment. The authors trace how systems thinking has shaped the emerging field of planetary health and compare traditional, more reductionist approaches to public health with frameworks that explicitly account for interconnected human, environmental, economic, and social systems. They review models including planetary boundaries, social-ecological systems, panarchy, and Raworth’s Doughnut framework, and use examples involving global food production and urbanization to show how policies can generate effects across multiple levels and timescales. The review also examines research and modeling on dietary change, transportation, land use, pollution, climate change, and health to illustrate how systems-oriented analysis can identify feedback, unintended consequences, trade-offs, and potential co-benefits for both human and natural systems.
A narrative review in public health that defines systems thinking through the four patterns and uses them as the organizing vocabulary for reasoning about planetary health. The four are adopted as the working definition rather than cited in passing.
