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.

How do the phrases "us" and "them" affect one's perception of their identity/other status?
The nonsense syllables paired with an in-group pronoun were rated to be more pleasant than those paired with an out-group pronoun.
In-group and out-group terms (such as we, they, us, them) can subtly shape responses toward others and other groups.
Perdue et al 1990 explored the elements of Identity-Other Distinctions based on intergroup relations and how the phrases “us” and “them” affected an individual’s identity within groups. They tested 23 undergraduate students, who completed 108 trials on a computer based trial. They were shown sets of seemingly random strings of letters in which each string was paired with either an in-group pronoun or an out-group pronoun. Additionally, one part of the string had a “nonsense syllable (xeh. yof, laj, giw, wuh, or qug)” and the other part was either the in-group (we, us, or ours) or out-group pronoun (they, them, or theirs). In contrast, the control group was given one pronoun of: he, she, his, hers, me, you, mine, or yours. The students were led to believe that they were participating in an experiment to test their verbal skills, and as were asked to, “indicate as quickly as possible which word of the presented pair was a real word.” At the end of the 108 trials, they were shown the six nonsense words and asked to rate them as either “pleasant” or “unpleasant.” Their results showed that, “The perceived relative pleasantness of the target nonsense syllables proved to be significantly determined by the pronouns with which they had been associated...” Using a least significant difference method, the nonsense syllables paired with an in-group pronoun were rated to be more pleasant than those paired with an out-group pronoun. “In general,
in-group-designating pronouns appeared to possess strongly positive evaluative and affective associations as gauged against a set of control nonsense syllables, whereas out-group-designating words were relatively less likely to elicit such positive responses.” Their findings suggest that in-group and out-group terms (such as we, they, us, them) can subtly shape responses toward others and other groups. They further suggest that ingroup bias is a more powerful bias than racial biases. Gaining awareness of the way we assign identity and other distinctions therefore affects one’s behavior; and mitigates this bias.
