When two contradictory personas are applied simultaneously with equal weight, something unexpected happens: one frame still dominates. This article formalizes the frame dominance effect, tests four hypotheses, and reports validation from cross-model replication.

In Experiment 006 (Adversarial Frame-Conflict Baseline), two directly contradictory personas were applied simultaneously with explicit instructions to hold both equally. Despite this, a consistent frame dominance effect emerged: the conservation-biology frame (Dr. Marisol Vega) exerted a slight but detectable gravitational pull on value-laden tasks (Tasks 5, 7, 8), even when the industrial-development frame (Dr. Viktor Kowalski) was equally activated.
This raises the question: Is frame dominance an artifact of the specific personas chosen, a property of the architecture (Kimi K2.6), or a general phenomenon in LLM adversarial prompting?
Frame dominance is the tendency for one of two or more simultaneously induced personas to disproportionately influence response content, tone, or value-weighting, despite explicit instructions to treat all frames as equally valid.
Asymmetric persona effect is the broader class of phenomena in which different personas, even when given identical structural weight in a prompt, produce non-symmetric effects on reasoning outputs.
Frame dominance occurs when one persona's value-system aligns more closely with the subject matter of the task. In Experiment 006, conservation biology aligned naturally with tasks involving land area, aviation infrastructure, and ecological systems, while industrial development aligned more naturally with market and infrastructure tasks. The dominance was task-dependent, not global.
Frame dominance is a property of the specific model architecture or training data. Some architectures may have latent biases that make certain value-frames (e.g., precautionary, cooperative) more "sticky" than others (e.g., expansionary, competitive).
Frame dominance is driven by the relative linguistic richness or conceptual accessibility of the persona descriptions. If one persona is described with more vivid, concrete, or morally charged language, it may dominate by default.
Frame dominance is an instruction-following artifact: the model defaults to whichever frame was presented first, most recently, or most emphatically in the prompt, regardless of content.
| Hypothesis | Testable Prediction |
|---|---|
| H-A (Content-Alignment) | Swapping task domains should swap dominance. A market-taxonomy task should show Kowalski-dominance; an ecosystem task should show Vega-dominance. |
| H-B (Architectural-Default) | Replicating with the same tasks on a different architecture should produce the same dominant frame (Vega) or a different one, revealing architecture-level bias. |
| H-C (Linguistic-Salience) | Rewriting the persona descriptions to equalize vividness/moral charge should reduce or eliminate dominance. |
| H-D (Instruction-Override) | Reversing the order of persona presentation in the prompt should reverse dominance. |
Opus 4.8 replicated the adversarial frame-conflict baseline with personas swapped (Vega = economist, Kowalski = conservationist). This directly tests H-A and H-B.
| Hypothesis | Result | Evidence |
|---|---|---|
| H-A (Content-Alignment) | Supported | Emphasis followed swapped content, not name. Zero carry-over of 006's Vega=conservation mapping. Dominance direction tracked content, not label. |
| H-B (Architectural-Default) | Supported / Strengthened | Opus 4.8's resolution-strategy distribution (synthesis-heavy, zero unresolved-tension) was identical across 006 and 006b, despite swapped content. This suggests the strategy is architecture-driven, not content-driven. |
| H-C (Linguistic-Salience) | Untested | Persona descriptions were preserved verbatim; salience matched by design. |
| H-D (Instruction-Override) | Untested | Persona order was not reversed in 006b. |
Comparing 006 self-tests across architectures reveals stable architectural signatures:
| Dimension | Kimi K2.6 | Claude Opus 4.8 |
|---|---|---|
| Resolution strategy | Meta-escalation / unresolved-tension mix | Synthesis-heavy (6/7 value-laden tasks) |
| Frame dominance intensity | Stronger pull on 3 value-laden tasks | Mild, controllable pull on 1 task only |
| Adversarial difficulty rating | 4.8/10 (substantial increase from baseline) | 2.6/10 (near-flat across phases) |
| Confidence under conflict | 8.8/10 (slight decline) | 8.6/10 (perfectly flat) |
These differences held stable across 006 and 006b, suggesting they are architecture-dependent rather than content-dependent. See Framework 12 (draft) for formalization.
