Cognitive computing describes AI systems designed to simulate aspects of human thought processes, such as learning, reasoning, and problem-solving, in a way that can interact naturally with people and adapt as it encounters new information. The term overlaps heavily with artificial intelligence in practice, and many people use the two interchangeably.
Where a distinction is drawn, cognitive computing is often used to describe systems explicitly framed as augmenting or collaborating with human decision-making, such as IBM Watson's early positioning, rather than fully automating a task. Some in the field prefer "cognitive computing" specifically because it avoids the science-fiction connotations that "artificial intelligence" can carry, framing the technology as a tool that extends human cognition rather than an independent or autonomous form of intelligence.
