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.

The investigation is concerned with the effects on judgement of some relations between the manner in which stimuli of a series are classified and the magnitudes of the stimuli. It is shown that when the classification stands in a direct and predictable relation to a physical scale, the stimuli belonging to different classes are judged as farther apart on that scale than in an unclassified series. A classification which is not coherently related to the physical scale does not affect judgement in this manner. There is also evidence in the results that, as a function of past experience with the classification, an increase occurs in the apparent differences between stimuli belonging to different classes, and in the apparent similarity of stimuli belonging to the same class. The relevance of these findings to the general problem of stereotyping is discussed.
How does the act of classification affect judgement?
When classification is imposed on participants, the judgments people made were altered.
The way that one thinks about an idea, person, or thing has an impact on the resulting mental model. Being aware of the way your patterns of thinking affect you can only lead to increased metacognition and allows one to try to mitigate their biases.
Tajfel and Wilkes (1963) found that classification has an increased effect on the behavior of judgement, when the experience is repeated throughout the experimental session. The purpose of their experiment was to examine the effect classification had on quantitative judgements. This was accomplished through judging the length of a collection of lines, so that the judgement (in this case, length) would be simple. After presenting the lines one by one in a sequential order, their results showed that when classification is imposed on participants, the judgments people made were altered. They postulated that this could be due to the repeated and frequent experience of the same class of stimuli, which could then strengthen the association to it. This includes an increase in both the subjective difference between classes, and the subjective similarities among classes of stimuli. This pattern is exemplified by stereotyping—when humans tend to highlight the differences of the other, and the similarities of the group they identify with. The more experience a person has with one class of stimuli, the more judgemental they are towards other classes.
