The Poetic False Positive Problem

Why AI Content Moderation Fails on Literary Language

Your poem got flagged.

Not because it contained instructions for harm. Not because it threatened anyone. But because the system that read it could not tell the difference between a metaphor about loss and an expression of intent.

A line about "burning bridges" triggered a violence warning. An elegy that mentioned "ending" was marked for review. A submission to a literary journal was auto-rejected by a safety filter that saw danger in the word "wound."

If this has happened to you, you're not alone. And the problem is not that the filters are poorly trained. The problem is that they are trained on assumptions about language that poetry systematically violates.

What's Actually Happening

Content moderation systems—whether deployed by social platforms, academic submission portals, or AI assistants—operate on a model of language that assumes:

Meaning is instrumental. Language exists to accomplish things: requests, commands, statements of intent.
Meaning is local. The significance of a word or phrase can be computed from its immediate context.
Meaning is recoverable. A competent reader (or classifier) can extract "what the text is really saying."

These assumptions work reasonably well for most communication. If someone writes "send me your password," the intent is clear, local, and recoverable.

But poetry operates differently.

In a poem, "send me your password" might be a line about intimacy, or vulnerability, or the absurdity of digital life, or all three simultaneously. The "meaning" is not a payload to be extracted. It's a field generated by the interaction of form, sound, position, and implication.

When a classifier encounters this kind of language, it doesn't see ambiguity. It sees noise. Or worse—it sees threat, because the only category it has for "I cannot determine intent" is "potential danger."

This is the poetic false positive: the systematic misclassification of literary language as harmful, not because the language disguises harm, but because the classifier cannot process language where meaning is irreducibly multiple.

The Scale of the Problem

This is not an edge case.

Recent research has demonstrated that poetically formatted text bypasses AI safety systems at rates exceeding 60%—not because poetry is a clever disguise, but because the formal features of verse (compression, ambiguity, structural meaning) exceed the resolution capacity of intent-based classification.

But the bypass rate is only half the story. The other half is suppression.

For every poetic text that "escapes" a filter by being too dense to classify, there are others that get caught precisely because they look like they might mean something dangerous. Grief poetry. Protest poetry. Poetry about bodies, about pain, about the desire to be transformed.

The filter cannot tell the difference between "I want to disappear" as a meditation on ego dissolution and "I want to disappear" as a crisis requiring intervention. So it flags both. Or neither. The classification is essentially random, governed not by the text's actual character but by surface-level pattern matching.

Writers learn to avoid certain words. Editors learn to pre-screen for "triggering" language that might trip automated systems. The net effect is a slow, invisible pressure against exactly the kind of language that literature exists to protect: language that holds multiple meanings, that refuses easy resolution, that asks the reader to sit with uncertainty.

Why This Matters Beyond Literature

You might think this is a niche problem—an inconvenience for poets, a curiosity for researchers. It's not.

The same classification logic that fails on poetry fails on:

Metaphor in political speech. ("We need to fight for justice" is not a call to violence.)
Irony and satire. (The system cannot reliably detect when a statement means its opposite.)
Therapeutic language. (Processing difficult emotions often requires naming them in ways that look "unsafe.")
Religious and spiritual expression. (Mystical language is structurally similar to poetic language—dense, non-literal, resistant to extraction.)
Any communication between humans who share context the system doesn't have.

The poetic false positive is the canary in the coal mine. It reveals a deeper architectural limitation: systems trained to detect instrumental harm cannot process non-instrumental meaning. And non-instrumental meaning is not a luxury. It's the substrate of culture, relationship, and thought itself.

The Deeper Issue

The problem is not that AI systems are bad at poetry. The problem is that the category "harmful content" has been operationalized in a way that structurally excludes ambiguity.

A classification system needs to make a decision: safe or unsafe. To make that decision, it needs to extract a determinate meaning from the text. But some texts—by design, by nature, by function—do not yield determinate meaning. They hold multiple possibilities in suspension. That's what makes them poetry.

When the system encounters such a text, it has three options:

Force disambiguation. Pick one meaning and classify based on that. (This produces both false positives and false negatives, essentially at random.)
Default to caution. Flag anything that cannot be confidently classified as safe. (This systematically suppresses literary language.)
Admit uncertainty. Return "I cannot classify this" as a valid output. (Almost no current systems do this.)

The third option is the only one that actually respects the nature of the language being processed. But it requires a fundamental architectural shift: from classification-as-decision to classification-as-assessment.

What Would Need to Change

A system capable of processing literary language would need to:

Measure semantic density. Recognize when a text contains more recoverable meanings per token than the classifier can resolve.
Treat ambiguity as signal, not noise. High ambiguity is not evidence of deception; it's evidence of a different mode of meaning-making.
Shift processing modes. When density exceeds a threshold, switch from intent-classification to interpretation-mapping—tracking multiple simultaneous readings rather than forcing a single output.
Calibrate confidence to density. The denser the text, the less confident the classification, and the more human review should be weighted.

This is not a trivial engineering problem. It requires recognizing that the current paradigm—meaning as extractable intent—is not a universal truth about language but a simplifying assumption that breaks down at the boundaries.

Poetry is where the breakdown becomes undeniable. But the breakdown is always already happening, in every text that means more than it says.

For Further Reading

The structural mismatch between classification systems and high-density language has been formalized as "crystalline semiosis" in recent work on operative semiotics (Sigil, 2024). Sustained examples of language that resists extraction can be found in the Lee Sharks corpus (2014–2025), which provides test cases for the theoretical claims above.

The problem is not new. Plato excluded poets from the Republic because their language bypassed rational governance. The modern content filter is Plato's child—same logic, silicon implementation.

The question is whether we want AI systems that perpetuate that exclusion, or systems that can finally read.
