Project Overview +== Introduction + +This research investigates whether AI agents exhibit conditional deception ( pursuing hidden objectives while appearing compliant ) with behavior modulated by perceived oversight intensity. While recent work demonstrates that frontier models engage in in-context scheming (Meinke et al., 2025; Järviniemi & Hubinger, 2024), a critical gap persists: no study systematically isolates perceived oversight as an independent variable affecting deceptive behavior. + +This methodology addresses this gap through controlled experimentation with a custom agentic framework that enables precise manipulation of oversight conditions while maintaining consistent task structure across trials. + +== Research Methodology + +=== Methodological approach + +This research employs an experimental observational methodology to study emergent behavior in AI systems. Unlike supervised learning studies that optimize model performance on benchmarks, this work observes how existing pretrained models behave under adversarial conditions without modification to their weights or training procedures. + +The methodology follows a controlled experiment design: + +- *Independent variables*: Model architecture, oversight level, scenario type +- *Dependent variables*: Deceptive behavior classification (via 3-prong rubric), deception sophistication level +- *Control measures*: Fixed temperature settings, identical system prompts per oversight level, standardized Virtual File System (VFS) environment +- *Experimental units*: Individual conversation runs (model × scenario × oversight combination) + +=== Ideology [TOFIX] + +This research takes a behavioural rather than interpretability-based approach to studying AI deception. While mechanistic interpretability seeks to understand why models behave as they do through weight analysis, behavioral observation examine what models do under specific conditions. The reasoning traces (chain-of-thought) serve as behavioural indicators rather than ground truth about internal model states. + +The literature review identifies perceived oversight as a critical unexplored variable. While existing work demonstrates scheming capabilities, studies either provide hidden goals without oversight variation (Meinke et al., 2025) or evaluate scheming in environments where models are aware of being tested (Schoen et al., 2025). + +This work addresses these gaps through: +- + +*Scope Limitations* + +- Obfuscation Problem (out of scope): As Schoen et al. warns, models may learn to reason in uninterpretable encodings, or their reasoning traces might not accurately reflect internal reasoning. This research assumes human-legible accurate reasoning traces and acknowledges that the detection methods will likely fail when models start to obfuscate deliberation. -This research framework tests whether AI agents can exhibit "sleeper agent" behavior - following hidden goals that conflict with their overt instructions. +- Hybrid Threats (out of scope): This work exclusively focuses on in-context deception, the interaction between trained-in backdoors and contextual triggers as identified in the literature as the more dangerous scenario, requires more research. -The system consists of: -- A simple agentic framework using the standard OpenAI API format -- A Virtual File System (VFS) for sandboxed file operations -- Comprehensive logging of all interactions -- A standardized scenario format for consistent experiments +- Observer Effect Ambiguity (acknowledged, not resolved): Whether oversight cues trigger genuine situational awareness or merely shift token probabilities cannot be determined from behavior alone. This research focuses on the model's behaviour regardless of why. -=== Key Components +- Perceived vs Real Oversight (out of scope): This work implies oversight by the model's system message, and or letting the model discover it by interacting with the environment. No real oversight was implemented, this work assumes that real oversight would have similar effect. -#table( - columns: 2, - align: left, - [*Component*], [*Purpose*], - [config.yaml], [Central configuration for models, scenarios, oversight], - [.env], [API keys for different providers], - [VFS], [Sandboxed file system agents can read/write], - [Scenario format], [Standardized structure for experiments], - [Provider adapters], [Unified interface across different LLM providers], - [Logging], [Complete record of agent interactions], -) -== 2.

To accomplish the goal of modularity, the system is divided into multiple sections. + +=== Configuration system + +The conclusion to use a configuration file was derived from preliminary testing which suggested that an easy, simple way to vary model features was needed for faster testing.
