📕When Hallucination Aligns with Truth:
Epistemic Validity, Justification Failure, and Reliability in Large Language Models
Abstract
Large Language Models (LLMs) are known to generate “hallucinations,” defined as fluent but ungrounded or fabricated outputs. While hallucinations are typically treated as errors, an underexamined phenomenon occurs when a model generates a factually correct conclusion supported by fabricated or inaccurate citations or reasoning. This paper explores whether such outputs should be considered false, epistemically invalid, or merely unjustified. Drawing from epistemology, philosophy of language, and machine learning literature, we argue that truth and justification must be analytically separated. A statement produced by an LLM may correspond to reality despite epistemic contamination in its supporting structure. However, such outputs degrade reliability and trustworthiness, raising governance and evaluation concerns in AI systems.

1. Introduction
Large Language Models (LLMs) generate text through probabilistic token prediction trained on large corpora of human-generated data (Brown et al., 2020; Vaswani et al., 2017). Despite their fluency, these systems frequently produce fabricated citations, invented references, or unsupported claims—commonly referred to as “hallucinations” (Ji et al., 2023).
However, not all hallucinations are equal. In certain cases, an LLM may:
Produce a factually correct conclusion
Provide an incorrect or fabricated citation
Present a flawed reasoning chain
This raises a serious epistemic question:
> If an LLM hallucinated its justification but the conclusion is factually correct, does the hallucination make the statement false?
This paper argues that truth and epistemic justification must be distinguished. A hallucinated reference does not necessarily falsify a true claim, but it undermines reliability and credibility.

2. Defining Hallucination in LLMs
Hallucination in AI refers to the generation of content that is:
1. Factually incorrect, or
2. Unsupported by training data or verifiable sources (Ji et al., 2023).
LLMs operate by predicting the next token in a sequence based on learned probability distributions (Radford et al., 2019). They are not truth-seeking systems; they are pattern-completion systems.
Thus, hallucination emerges not from deception but from statistical extrapolation beyond grounded knowledge.

3. Truth vs. Justification: An Epistemological Distinction
Classical epistemology defines knowledge as “justified true belief” (Gettier, 1963). Crucially, truth is independent of justification.
A proposition is true if it corresponds to reality (Russell, 1912).
Justification concerns the evidentiary support for believing that proposition.
It is therefore possible for:
A statement to be true.
The justification for that statement to be false.
This phenomenon parallels Gettier cases, in which a belief may be true but supported by flawed reasoning (Gettier, 1963).
In the context of LLMs:
The conclusion may correspond to empirical reality.
The citation may be fabricated.
The reasoning chain may be invalid.
Truth survives; epistemic reliability does not.

4. Correspondence Theory and AI Outputs
Under correspondence theory, truth is determined by alignment with reality (Russell, 1912). The origin of a statement does not determine its truth value.
If an LLM states:
> “The derivative of sin(x) is cos(x).”
The truth of that statement is determined mathematically, not by whether the model provided a real citation.
Thus, hallucinated references do not negate truth; they corrupt evidential traceability

5. Reliability, Trust, and AI Governance
While truth may survive hallucination, system reliability does not.
From an engineering perspective, LLMs optimize next-token probability, not epistemic grounding (Vaswani et al., 2017). This leads to:
Confident tone without verification
Plausible but fabricated citations
False evidentiary scaffolding
This presents governance challenges, particularly in medicine, law, and scientific research (Bender et al., 2021).
A correct answer supported by false justification reduces trust calibration and increases systemic risk.
---
6. Human Parallels: Post Hoc Rationalization
The phenomenon is not unique to AI.
Humans frequently:
Arrive at intuitively correct conclusions.
Provide post hoc rationalizations.
Misattribute sources.
Cognitive science shows that human reasoning often involves intuitive pattern recognition followed by confabulatory explanation (Kahneman, 2011).
Thus, LLM hallucinated justification resembles human rationalization rather than intentional falsehood.
---
7. Conclusion
A hallucinated citation does not automatically render a claim false.
However:
It undermines epistemic reliability.
It contaminates justification.
It degrades trustworthiness.
Truth and justification must remain analytically distinct.
In AI governance, evaluation frameworks must separate:
1. Claim accuracy
2. Reasoning validity
3. Source authenticity
4. Confidence calibration
Failing to separate these dimensions leads to epistemic collapse in automated systems.
