Abstract
As generative AI transforms work across all fields, understanding human–AI collaboration is critically important to the future of work. This study analyzed behavioral data from millions of Claude AI conversations mapped to occupational tasks via the O*NET taxonomy to examine whether human–AI collaboration patterns are consistent with expectations derived from traditional technology adoption frameworks. Utilizing Technology Acceptance Model, Protection Motivation Theory, Social Exchange Theory, and Socio-Technical Systems Theory as parallel lenses on post-adoptive behavior, the analysis examined how interaction patterns predict AI usage intensity, risk-management behaviors, and the development of cognitive partnerships. Results demonstrated that collaborative interaction patterns, including iterative refinement and learning-oriented exchanges, predicted significantly higher AI usage intensity, consistent with expectations derived from TAM. Contrary to Protection Motivation Theory predictions, risk-management behaviors such as validation and feedback loops were positively associated with usage intensity, suggesting these function as protective engagement strategies that enable continued use, not resistance mechanisms. Analysis of extended thinking mode usage suggested distinct trust pathways: delegation trust, where users rely on AI’s autonomous reasoning, versus collaboration trust, built through iterative dialogue, although sensitivity analyses indicate that task complexity may partly account for this divergence. A cross-level reversal emerged whereby augmentation patterns positively predicted usage intensity at the task level but negatively predicted user adoption at the cluster level, indicating that depth and breadth of AI use follow different dynamics. These findings challenge assumptions that caution suppresses AI use and suggest that effective human–AI partnership supports cognitive partnerships through multiple complementary pathways. For practitioners and leaders, supporting diverse ways of interacting with AI can be important for successful integration. The analyses drew on the Anthropic Economic Index dataset of 3,365 occupational tasks grouped into 593 task clusters, with model sample sizes varying by hypothesis.
