The saying that humans only use 10% of their brain power is a myth that has been debunked by neuroscientists over the years. However, the idea that we aren’t tapping into the full potential of our minds still resonates with many. As artificial intelligence (AI) becomes increasingly integrated into the workplace—especially in finance—many professionals are left wondering how it might impact how much of our brains we actually use. Will we rely more on AI and end up using less of our brain? Or will AI push us to think more creatively and use our cognitive abilities in new ways?

For finance employees and job seekers, the relationship between AI and cognitive function has important implications. Let’s explore how AI may influence brain usage in the context of the finance industry and beyond.

AI and Cognitive Load: Will It Lighten or Increase the Load?

One of the primary benefits of AI is its ability to automate routine, repetitive tasks. In finance, AI is used for data analysis, algorithmic trading, fraud detection, risk management, and even customer service. These tasks, which would require significant time and effort from humans, are increasingly handled by machines.

In theory, this automation could lead to a lighter cognitive load for finance professionals. By offloading more of the data-heavy, monotonous tasks to AI systems, employees might have more mental bandwidth for creative, strategic, and complex decision-making. In this way, AI could free up cognitive resources, allowing us to focus on higher-level thinking, such as analyzing market trends, developing innovative solutions, or advising clients on strategic decisions. This could lead to a more efficient and intellectually fulfilling use of brainpower.

However, there’s another side to consider. As finance professionals rely more heavily on AI, there’s the potential for cognitive complacency. If AI takes over the bulk of routine analysis, individuals may no longer need to engage in some of the cognitive processes that would normally develop through practice. This might reduce the need for deep problem-solving or critical thinking in certain areas. The challenge, then, is to strike a balance—ensuring that AI supports our cognitive abilities without leading to a decline in mental engagement.

Creativity and Decision-Making: A New Way to Use the Brain

AI’s potential to enhance human creativity and decision-making is one of its most exciting aspects. While AI can analyze vast amounts of data and recognize patterns that would take humans much longer to identify, it still requires human guidance to define the problem, interpret the results, and make meaningful decisions.

In the finance sector, AI-driven systems can process and analyze large data sets more efficiently than humans ever could. However, humans are still needed to understand the nuances of that data, contextualize it, and make decisions based on factors that AI might not be able to fully account for. This process requires higher-order cognitive functions, such as judgment, intuition, and abstract thinking.

Rather than using less of our brain, AI could push us to engage more with our creative and analytical abilities. Finance professionals might focus more on designing innovative solutions, strategizing long-term plans, and identifying emerging trends, all while leveraging AI to handle more of the technical work.

AI and Continuous Learning: Expanding Brain Function?

With the increasing presence of AI in finance, professionals are being pushed to develop new skills, such as understanding how AI systems work, learning to collaborate effectively with these systems, and interpreting data-driven insights in novel ways. In fact, the rise of AI may encourage more continuous learning and cognitive growth.

AI tools often require users to think in new ways, challenging traditional methods of working and encouraging more out-of-the-box thinking. By learning how to effectively integrate AI into daily workflows, finance employees can expand their mental toolkit, acquiring new skills that strengthen cognitive flexibility.

The ongoing interaction between humans and AI can drive the brain to develop new neural connections as individuals adapt to the changing landscape of the finance industry. This can lead to increased cognitive engagement as professionals continue to learn, innovate, and find ways to use AI more effectively.

Efficiency vs. Over-Reliance: Striking the Balance

The most important consideration when it comes to AI and brain power is how finance professionals choose to integrate AI into their workflows. AI has the potential to enhance human capabilities, but over-reliance on machines could lead to a decrease in cognitive effort in certain areas.

For example, if finance professionals start to lean too heavily on AI tools for analysis and decision-making without fully understanding how the system arrives at conclusions, they may become less adept at critically evaluating the results. Over time, this could reduce cognitive engagement and mental sharpness.

To ensure that AI leads to more brain usage, it’s essential for professionals to maintain active involvement in the decision-making process, continuously challenge AI-generated insights, and stay informed about the evolving technologies they are working with. The goal should be to use AI as a supplement to human cognition, not a replacement for it.

Using More of Our Brain with AI

While AI may reduce the need for cognitive effort in routine tasks, it also has the potential to encourage more strategic thinking, creativity, and continuous learning. Far from making us use less of our brain, AI could be a tool that challenges us to think in new ways, push our cognitive limits, and engage more deeply with our work.

For finance professionals, the key to thriving in an AI-driven world will be to embrace the opportunities that come with this technology, while remaining actively involved in the critical thinking, decision-making, and problem-solving that AI cannot replicate. By doing so, we can ensure that AI helps us unlock more of our brain’s potential, leading to a smarter, more efficient, and more innovative finance industry.
