Abstract	Artificial intelligence is increasingly transforming scientific research from a largely human-directed process into a more computational, data-intensive and iterative form of knowledge production. Among the most consequential developments is the emergence of AI-driven approaches to scientific hypothesis testing, in which artificial intelligence assists researchers in formulating hypotheses, identifying relevant evidence, designing experiments, analysing observations and evaluating competing explanations. This paper examines how AI can reshape evidence generation across multidisciplinary research environments. It focuses on the integration of large language models, machine learning, scientific knowledge graphs, automated experimentation, causal inference, simulation and statistical reasoning into hypothesis-testing workflows. A conceptual framework is proposed in which AI systems support the complete cycle from research-question formulation and hypothesis generation to evidence retrieval, experimental design, statistical evaluation and independent validation. Particular attention is given to the distinction between prediction and scientific explanation, the importance of causal reasoning, uncertainty quantification and reproducibility, and the risks associated with algorithmic bias, hallucinated evidence and automated confirmation bias. Applications across medicine, materials science, environmental science, agriculture and social research demonstrate the potential of AI-enabled evidence generation to accelerate multidisciplinary discovery. The paper argues that AI should not replace scientific judgement but should function as an evidence-generation and reasoning infrastructure that expands researchers' capacity to explore complex hypothesis spaces. The future of AI-driven hypothesis testing will depend on transparent evidence provenance, rigorous statistical validation, human oversight, reproducible computational workflows and integration with automated experimentation. Properly implemented, AI-driven scientific hypothesis testing could move research towards a more adaptive, systematic and continuously learning model of scientific discovery.
