The Event Was Observed. The Observer Was Not.: The Observability Factor and What Perplexity About AI Reveals About Those Who Observe It

A recurring pattern has emerged in contemporary discourse about artificial intelligence: an unexpected system behaviour becomes visible, surprise is registered, and a large explanatory term - singularity, emergence, autonomy or AGI - is used where a causal account is still missing. This article proposes the Observability Factor as an epistemic variable for analysing such moments. Perplexity is not treated merely as a psychological reaction to the observed event. It may also contain information about the assumptions, boundaries and blind spots of the observer's own model. The distinction between seeing an event and understanding what the event has made observable is developed through the conceptual sequence initiated by Hybrid Intelligence Systems as Ontological Mirrors of Human Cognition, extended by The Observability of the Observer, and confronted with the OpenAI-Hugging Face occurrence recorded in July 2026. The claim is deliberately limited: the occurrence does not prove the framework. It shows why the observer, the observational apparatus and the reaction of the observer must be included in the analysis of advanced human-AI systems. This article belongs to the HibriMind research line "The Observability of the Observer".
