Study: AI Is Making Us All Dumber

According to a new study, letting AI take over more tasks reduces the type of brain workout that helps people learn.

Well, it’s official: An increased reliance on artificial intelligence has been linked to diminished critical thinking abilities, a new study has found.

This might not come as much of a surprise to any AI naysayers out there. AI tools are huge timesavers, but they’re also a great way to avoid reading, writing, and other activities that can function as a mental gym.

But are AI tools a complete dead end for human advancement, or do they still have a place within a well-rounded tech diet? Here’s how the new study went about determining the downsides of AI, and the specifics of what it found.

The study, out this month in Societies, is titled “AI Tools in Society: Impacts on Cognitive Offloading and the Future of Critical Thinking.” It pulls from a mix of surveys and interviews covering 666 UK participants across a range of age groups and educational backgrounds, completed by Michael Gerlich at SBS Swiss Business School.

According to the study, the problems were more of a concern for younger people: “Younger participants exhibited higher dependence on AI tools and lower critical thinking scores compared to older participants.”

In the end, AI tool reliance was a problem due to cognitive offloading, the term for the action of “delegat[ing] cognitive tasks to external aids, reducing […] engagement in deep, reflective thinking.”

In other words, letting AI take over more tasks reduces the type of brain workout that helps people learn. 

All isn’t lost however, as the study’s findings lead to a simple recommendation to address the problem:

“These results highlight the potential cognitive costs of AI tool reliance, emphasizing the need for educational strategies that promote critical engagement with AI technologies.” – the study

Granted, the solution falls on our overworked educational system, which may not be able to handle yet another pivot in how it educates our youth. However, the answer seems easy enough. We just need to make sure that we’re not losing our ability to critically engage with our work, even if AI tools are serving to complete some of the effort.

This aligns with the warnings that already abound surrounding the use of generative AI chatbots. The biggest one is that they can hallucinate the summaries or answers that they deliver, so all users should take any definitive statements that an LLM offers with a grain of salt.

The study doesn’t get into the larger implications of AI adoption, but AI tools are currently being rolled out as value-adds to countless software services.

At the same time, C-suite executives everywhere are practically salivating at the idea of cutting their workforces in half under the assumption that the still-unrealized power of AI can make up the difference.

In moderation, a little cognition offloading can be helpful. After all, assistive technology from PCs to smartphones have offered plenty of cognition offloading for decades now. But the potential for overdoing it – according to studies like this new one – remains high.

Like it or not, AI is reshaping the modern world. Let’s hope it’s for the better.
