How do ChatGPT and Gemini affect you? MIT study brings unpleasant results

  • A new study by MIT (Massachusetts Institute of Technology) shows how AI affects the human brain
  • The results suggest that users of generative AI have lower performance and greater frustration when working independently
  • The long-term impact on creativity and decision-making may be more serious than expected

Jak ChatGPT a Gemini ovlivňují uživatele při psaní

Generative artificial intelligence, meaning AI that creates various types of content for you (texts, images, code, etc.), has become a common tool for many people, whether at work or in their free time. However, what always seemed revolutionary also has a predictably dark side. This fact is now underscored by the Massachusetts Institute of Technology, which conducted a study based on a request from Microsoft.

The institute’s study suggests that regular use of AI tools like ChatGPT can lead to so-called cognitive debt, and thus a decline in the ability to think, evaluate, and create independently.

Modely ChatGPT pro psaní textů

MIT researchers conducted the study by dividing 54 participants aged 18 to 39 into three groups. The first group was allowed to use generative artificial intelligence, specifically the ChatGPT and Gemini models, when writing the assigned essay.

Another group had access only to search engines, such as Google. The third group worked without any tools.

What did the results of the ChatGPT and Gemini usage study show?

According to the results table on pages 3 to 4 of the study PDF document, artificial intelligence users showed the following results:

  • lower scores in output quality and text structure
  • greater frustration during subsequent independent writing
  • lower cognitive activity, measured through neuropsychological tests

The study also points out that artificial intelligence like ChatGPT and Gemini often amplifies the so-called „confirmation bias,“ which is a person’s tendency to seek information that confirms their existing opinion; this may also be because AI is trained on vast datasets that reflect human preferences.

The result could potentially be greater societal polarization and a decline in open interpersonal dialogue in the future. It should be added, however, that the study has not yet been peer-reviewed and does not address long-term effects in detail.

Nevertheless, researchers warn that if the trend is confirmed, it could significantly affect creativity, problem-solving ability, and the capacity for independent thinking.
