Human-AI collaboration is revolutionizing decision-making by integrating AI’s computational power with human intuition, ethical reasoning, and contextual understanding. This paper explores the transformative impact of AI-assisted decision-making, examining how AI enhances efficiency, minimizes cognitive biases, and offers data-driven insights across various domains. While AI enables more informed and objective decisions, its integration raises critical challenges related to algorithmic transparency, interpretability, and ethical accountability. Organizations must establish governance frameworks that balance AI automation with human oversight to ensure responsible and effective decision-making. Furthermore, the paper investigates the psychological and organizational implications of AI in leadership, employee trust, and decision autonomy. As AI continues to evolve, interdisciplinary research and regulatory measures will be essential to shaping ethical and transparent AI-driven decision-making processes. Rather than replacing human judgment, AI should serve as an augmentative tool that empowers individuals and organizations to make more strategic, equitable, and informed decisions in an increasingly complex world.
