Does AI weaken thinking ability?

Generative artificial intelligence (AI) tools such as ChatGPT, Claude, Gemini, and DeepSeek are fundamentally altering how humans work, learn, and generate ideas. Tasks that previously required hours of effort can now be completed in minutes with a single command. While this technology undeniably enhances efficiency, a growing debate centers on whether AI strengthens human cognitive abilities or fosters an over-reliance on machines.

Global data indicates a rapid expansion in AI usage. A Microsoft AI Economy Institute report projects that nearly one-sixth of the world's population will use generative AI in their work. Furthermore, research by Microsoft and LinkedIn reveals that 90% of users acknowledge AI's role in increasing productivity, enabling them to focus on high-value tasks (85%), and boosting creativity (84%). This trend is also evident in Malaysia, where the EY Work Reimagined Survey found that 93% of workers use generative AI daily, with 76% reporting increased productivity. The Malaysian government is actively promoting AI through the National AI Office (NAIO), anticipating significant contributions to national productivity.

However, excessive dependence on AI can erode critical thinking skills. The phenomenon of cognitive offloading occurs when individuals delegate memory recall, analysis, and decision-making processes to machines. A study from MIT Media Lab suggests that ChatGPT users exhibit lower brain activity, memory engagement, and creativity levels compared to those who complete tasks without AI assistance. This challenge is particularly pronounced in education, where a significant percentage of students reportedly use generative AI for academic support. While AI can simplify understanding and expedite assignments, a reliance without genuine comprehension can lead to shallower learning experiences.

Students may arrive at correct answers but fail to develop essential skills in critical thinking, analysis, and independent problem-solving. The true potential of AI lies in its role as a tool to augment human capabilities, not replace the cognitive process itself. The ability to evaluate, question, make judgments, and generate novel ideas still requires human wisdom. Therefore, the critical challenge is to ensure that individuals continue to train their minds for critical, creative, and discerning thought. AI can accelerate work, but only humans can apply knowledge and wisdom to make sound and responsible decisions.
