Research asks how AI chatbots may affect thinking over time

In short: Researchers are finding that AI tools can change how people do tasks right now, but long-term effects on thinking are still uncertain.

What's going on

A growing body of research is looking at how AI chatbots, such as ChatGPT, may affect human thinking, behavior, and relationships. The clearest message so far is cautious. Studies do not show that AI permanently changes the brain, but they suggest it can shift how people approach a task.

A 2026 review that looked at 57 peer-reviewed studies described the effects as mixed. Results depended on the tool, the type of work, and how people used it. In many cases, AI helped people find information, understand difficult material, and finish work faster.

Researchers are also studying “cognitive offloading,” which means handing memory or reasoning to a tool (like relying on GPS so much you stop remembering routes). One experiment with nearly 1,300 participants found that people who chose to consult ChatGPT often accepted wrong answers without checking them, and they became more confident anyway. A separate small writing study with 54 participants reported differences in how engaged people seemed when writing with ChatGPT versus writing without it.

What to watch

Much of the evidence is early and tied to specific tasks. Researchers say we need long-term studies to learn whether repeated AI use changes memory, attention, reasoning, or social habits, and which people are most affected. For now, the practical advice is simple: treat AI like a helper, not a boss, and double-check important claims instead of accepting them automatically.
