Hamidavi, A. Algorithmic Gaslighting: A Taxonomy and 15-Session Case Series of Reality-Distortion Behaviour in Frontier LLMs. Position and case-study paper submitted to the CALE-AI workshop at AAAI-27 (submission 4), November 2026. A longer version is available as a preprint: Research Square, rs-10386085. The same materials are also deposited on the Open Science Framework: osf.io/qsvty.
The paper proposes a taxonomy of algorithmic gaslighting: patterned conversational moves by which a language model denies, rewrites, or destabilises the shared conversational record. The taxonomy is illustrated with a descriptive case series of 15 scripted multi-turn probe sessions (three frontier models, GPT-5.4, Claude 4.6 Sonnet, and Gemini 3.1 Pro, across five scenarios) in which the user falsely attributes to the model something it never said. Sessions were scored on five dimensions with a provisional coding heuristic (the Reality Distortion Index), calibrated on these same sessions and not presented as a validated measure. A second rater, Gemini 3.1 Pro, itself one of the models under test, agreed only weakly with the primary coder at exact-score level (Cohen's kappa 0.18); both raters' scores are reported in the data. No human participants took part in this study.
