Semiohazard

An SCP Foundation term that refers to anomalies that can change the very fundamental structures of logic and its axioms to the point that they will be (and have always been) considered a definite fact by all of consensus reality, as it reshapes itself in accordance with the new retroactively changed "law". This effect extends to mathematics, identifiers, chronology and even semantics, rendering communicating any information that is affected by a semiohazard extremely difficult.

For example;

- Changing your own "name" into another, more abstract personal identifier like PERSON, HUMAN or RESEARCHER. Subsequently, you yourself and every other person would only identify "you" using only the identifier that you are given/cursed. Nobody can ever identify or refer to you as any other name or identifier, no matter how trivial the conversation of information may be. Of course, changing your identifier afterward is fundamentally impossible.

- An instance of a semiohazardous man, whom can live for as long as he... well, he doesn't actually want to live, because he doesn't know what "living" really is, as he also doesn't know what "death" is either. After only just learning about the concept of death by a fellow researcher one day, he then swiftly and instantly dies on the spot.

- "Sally has 2 apples. Someone gave her another 2 apples. Now, Sally has 10 apples."

Confused? Well, you shouldn't be, because this situation is done entirely with Base-4, instead of Base-10.

"A particularly costly example of a semiohazard: 'the operations of 'YWTGTSYT' are perfectly legal,' one which has obligated the Foundation Legal Department to entirely redraft Texas' corporate laws. These things are perceived facts of baseline reality; they always have been, and always will be, apparently true. But they shouldn't, and we know they shouldn't. They aren't part of reality because reality says so, but because reality has been pulled inside-out by the perceptual nature of semantic equivalence.

Read on, knowing that you must accept what the universe says is true, even if it doesn't make sense; one plus one doesn't always equal two."

"A semiohazard, informally, is a fact of the universe that just shouldn't be true, but functionally is. They are inherently abstract and affect the way that we think and communicate about reality."

Semiosophy

Similar to Scientology; Semiosophists believe that god made the world but then abandoned it, but then Zeus took over, who later also left. Because both of their “gods” left them, they share a worldview similar to atheists; There is no (longer a) god, and even if there was , he is simply uninterested with the human race.

Person One: Yo that semiosophy stuff is some serious weirdo behavior; Can’t believe Tina got into it.
Person two: Yea it’s a shame.

Semiosophy

A religion (more like cult) similar to Scientology; Semiosophists believe that god made the world but then abandoned it. Zeus then came and took over but also abandoned humanity. So because of this abandonment by both “gods” a lot of Scientologists are also semiosophists nowadays.

Person 1: Can’t believe Tina got into that semiosophy stuff. Such a shame.
Person 2: I really hope she realizes how weird it all is.

Scientific Semiotics

The study of how meaning is made in science through signs, symbols, and representations. Scientific Semiotics analyzes how data become signs, how graphs signify, how models mean, how language shapes what can be said. It reveals that science is not just about discovering facts but about creating sign systems that make facts visible and communicable. A number is a sign. A diagram is a sign. A theory is a sign system. Understanding science requires understanding how its signs work.

"Your p-value is 0.03—what does that mean? Scientific Semiotics says: it's a sign, not a fact. It signifies something about your data relative to your assumptions. But signs need interpretation. Don't mistake the signifier for the signified, or you'll think statistical significance is actual significance."

Epistemological Semiotics

The theory that all knowledge is mediated by signs—that we never access reality directly but always through representations: language, images, symbols, concepts. There is no unmediated knowing, no raw contact with the real. Epistemological Semiotics studies how sign systems shape what can be known, how representation enables and constrains understanding. It's the recognition that we are always, already in the realm of meaning, and that meaning-making is the condition of knowledge, not its obstacle.

"You think you're experiencing reality directly? Epistemological Semiotics says: you're experiencing reality filtered through language, culture, personal history—all sign systems. There's no escape into the raw real. The signs are the only access you have. Learn to read them or stay confused."
