From Scalars to Tensors: Declared Losses Recover Epistemic Distinctions That Neutrosophic Scalars Cannot Express
This paper demonstrates that while neutrosophic scalar evaluations (Truth, Indeterminacy, Falsity) reveal widespread "hyper-truth" across diverse LLMs, they fail to distinguish between fundamentally different epistemic states like paradox and ignorance, a limitation that is resolved by augmenting scalar outputs with structured, domain-specific loss declarations to form a more faithful tensor representation of model uncertainty.

The Big Idea: Why "Maybe" Isn't Enough
Imagine you are asking a group of expert chefs (AI models) to rate a very confusing dish. You ask them: "Is this delicious (Truth), is it weird/unclear (Indeterminacy), or is it gross (Falsity)?"
Previous research showed that when chefs aren't forced to make their answers add up to 100%, they often say, "It's 100% delicious AND 100% weird AND 100% gross." This is called "Hyper-Truth." It proves that AI can feel multiple conflicting emotions at once, which is more honest than forcing them to pick just one.
But this paper found a problem: Even with this new "Hyper-Truth" method, some chefs still give the exact same answer for three completely different problems. They collapse all confusion into a single, boring "I don't know" score.
The authors say: "We need to stop just asking for a score. We need to ask the chefs to write a note explaining why they are confused."
The Problem: The "Black Hole" of Confusion
The paper identifies a specific issue called the "Absorption Problem."
Imagine three very different situations:
- A Paradox: A sentence that says, "This sentence is false." (Logic is broken).
- Ignorance: "How many stars are in the universe?" (We literally don't have the data).
- Contingency: "Will it rain tomorrow?" (It depends on the future).
In a perfect world, an AI should treat these differently. But the paper found that some AI models (like Llama and Mistral) treat all three exactly the same. They give a score of:
- Truth: 0%
- Indeterminacy: 100%
- Falsity: 0%
The Analogy:
Imagine a weather forecaster who, when asked about a hurricane, a snowstorm, and a gentle breeze, simply says, "It's just weather."
- They aren't lying.
- They aren't stupid.
- They just don't have a way to say the difference using only the word "weather."
The AI has the internal knowledge that a hurricane is different from a breeze, but the "scorecard" (the 3 numbers) is too small to hold that detail. It swallows (absorbs) all the nuance into a single "I don't know" bucket.
The Solution: The "Tensor" (Scorecard + Diary)
The authors propose a new way to talk to AI. Instead of just asking for the three numbers (Truth, Indeterminacy, Falsity), they ask the AI to also write a "Declared Loss."
Think of this as adding a diary entry to the scorecard.
- The Scorecard: "Confusion Level: 100%."
- The Diary: "I am confused because this sentence refers to itself, which breaks logic." OR "I am confused because I cannot see the future." OR "I am confused because I lack data on star counts."
The Results:
When the researchers tried this:
- The Scores stayed the same: The AI still gave the same "100% confusion" number for the paradox and the ignorance.
- The Diaries were totally different: The words the AI used to explain the paradox were completely different from the words it used for ignorance.
- Paradox Diary: "Self-reference," "Logical loop," "Bivalence limits."
- Ignorance Diary: "Empirical data," "Measurement limits," "Unknowable."
By adding the "diary" (the tensor), they recovered the distinctions that the "scorecard" (the scalar) had lost.
Why This Matters (The "So What?")
This changes how we should trust and use AI.
- Don't just look at the number: If an AI says "I'm 50% sure," that number is useless if you don't know why it's unsure. Is it unsure because the math is broken? Or because it's missing data?
- Better Safety: If you are building a self-driving car, you need to know if the car is confused because of a "glitch in the code" (Paradox) or because "it's too foggy to see" (Ignorance). The solution is different for each!
- Honest AI: The paper proves that AI models are actually smarter than their output formats let them show. They have the answers in their "head," but they need a better way to "speak" them.
Summary Analogy
- Old Way (Probabilities): Asking a student to grade a test with only "Pass" or "Fail."
- Middle Way (Neutrosophic Scalars): Asking the student to give a score of 0 to 100. (Better, but still vague).
- New Way (Tensors with Losses): Asking the student for a score AND a written explanation of exactly which questions they struggled with and why.
The paper concludes that to truly understand what an AI knows (and doesn't know), we must stop treating them like calculators and start treating them like experts who need to explain their reasoning. The "Tensor" (Score + Explanation) is the only way to get the full picture.
