New study reveals what too much AI use does to your brain and it's eye-opening for anyone who uses it every day

A new study looked at what happens to your brain from excessive use of artificial intelligence (AI) in the workplace – and it’s not good news.

AI has come a long way in a relatively short period of time, with millions of people now regularly using it.

It can offer assistance on a whole range of things, from summarizing long articles to cutting down your bills. 

However, a new study shared in the Harvard Business Review has revealed that it might not be as helpful as you think.

A new study has looked into AI use in the workplace

AI is still a pretty new technology, which means studies into the long-term impact are ongoing. 

However, one study from last year found that people who regularly rely on AI ‘developed shallower knowledge’ of a topic than those who didn’t – in effect making you a little stupider. 

Meanwhile, a Harvard professor said he had noticed something concerning about people who use chatbots excessively.

Now a more recent study from Boston Consulting Group has found that regular use of AI agents while working can cause ‘brain fry’. 

The researchers looked specifically at artificial intelligence in the workplace, and found that workers were experiencing mental fatigue caused by ‘excessive use or oversight of AI tools beyond one’s cognitive capacity’. 

The study said that while using one, two or three tools, workers will typically experience a boost in productivity, but once more tools are added this drops. 

“Contrary to the promise of having more time to focus on meaningful work, juggling and multitasking can become the definitive features of working with AI,” the study authors said. 

“This AI-associated mental strain carries significant costs in the form of increased employee errors, decision fatigue, and intention to quit.”

One worker who took part in the study said that with several artificial intelligence tools running, his brain began to ‘feel cluttered’ and ‘crowded’ – comparing it to having ‘a dozen browser tabs’ open in his head. 

Workers across some job roles were harder hit than others

The study was conducted on 1,488 full-time US-based workers, across various roles, industries, and professional levels. 

In total, around 14 percent said they had felt some form of ‘brain fry’ while at work. 

But that number wasn’t evenly distributed across roles and industries. 

At the lower end of the scale, only 6 percent of people working in legal or compliance roles reported experiencing brain fry. 

Management and leadership roles also reported lower scores of 8.6 percent. 

However, at the other end, almost 26 percent of people working in marketing complained of experiencing brain fry, alongside almost 20 percent of human resources workers.
