Is AI Really as Smart as We Think? Breaking Down AI's Limitations

Can AI Really Reason Like Humans? A New Study Questions AI’s Problem-Solving Abilities

Artificial intelligence (AI) is becoming a powerful tool in everyday life, from assisting with customer service to analyzing large datasets. But a crucial question remains: Can AI actually reason like a human? A recent study by researchers at Apple suggests that the answer may be no—or at least, not yet.

The study, titled "Understanding the limitations of mathematical reasoning in large language models (LLMs)," has sparked discussions within the AI community. It reveals a fundamental flaw in current AI models: they often fail when asked to solve even slightly altered math problems that require basic reasoning. This discovery challenges the growing belief that AI models, like the popular GPT-based systems, are capable of "thinking" or reasoning as humans do.

Why AI Stumbles on Simple Math Problems

The researchers presented a simple math problem to test the AI model’s ability to solve it. For example:

"Oliver picks 44 kiwis on Friday. He picks 58 kiwis on Saturday. On Sunday, he picks double the number of kiwis he did on Friday. How many kiwis does Oliver have?"

The answer is straightforward: 44 + 58 + (44 * 2) = 190 kiwis. AI models, including large language models (LLMs), can usually handle such simple arithmetic correctly.

However, when the researchers added a trivial detail, the AI model stumbled. Here’s the modified version:

"Oliver picks 44 kiwis on Friday. He picks 58 kiwis on Saturday. On Sunday, he picks double the number of kiwis he did on Friday, but five of them were a bit smaller than average. How many kiwis does Oliver have?"

The detail about the size of the kiwis should be irrelevant—the math remains the same. Yet, some of the AI models got confused (GPT-4o got it rightly :)) .

This is just one example, but the researchers found that these types of small, irrelevant details consistently confused the AI models, leading to incorrect answers in many cases.

Why Does This Happen?

The failure of AI to handle such simple problems raises an important question: Why does adding a minor detail confuse these models?

The researchers propose that AI models don’t truly understand the problems they are trying to solve. Instead, they rely on patterns observed in their training data to replicate reasoning steps. When they encounter something slightly outside those patterns—such as the mention of "smaller kiwis"—the model can’t correctly interpret how to handle that extra information.

As the researchers explain:

"We hypothesize that current LLMs are not capable of genuine logical reasoning; instead, they attempt to replicate the reasoning steps observed in their training data."

In other words, the AI is mimicking reasoning based on the data it has seen before, but it doesn’t actually "think" or "reason" the way humans do. It’s more like pattern recognition than true problem-solving.

The Broader Implications: Can AI Really "Think"?

This raises deeper questions about AI’s limitations. While AI models can mimic complex reasoning chains, their performance deteriorates when the task becomes more complex or when new, unfamiliar details are introduced. For instance, the phrase "I love you" is often followed by "I love you too" in training data, so AI can repeat it, but it doesn’t actually feel love.

This disconnect between mimicking and understanding highlights a significant limitation of AI, particularly in areas like mathematics, reasoning, and problem-solving.

One OpenAI researcher suggested that these issues could be fixed with prompt engineering, which involves carefully phrasing the input to guide the model to a better answer. However, as the study’s co-author Mehrdad Farajtabar pointed out, this solution would only work for simple deviations. More complex distractions would require exponentially more data and contextual information—something a child could intuitively understand but an AI model might not.

What Does This Mean for AI's Future?

So, does this mean AI can’t reason at all? Not necessarily. As AI research is advancing rapidly, it’s possible that AI models may develop reasoning capabilities we don’t fully understand yet. However, for now, the study reveals a cautionary tale: AI may not be as advanced in reasoning as we sometimes assume.

This discovery is especially important as AI becomes integrated into more aspects of our daily lives—from decision-making in businesses to personal assistance tools. If AI can easily be tripped up by irrelevant details in math problems, what does that say about its reliability in more complex, high-stakes scenarios?

How Should Businesses and Organizations Respond?

As AI continues to evolve, it’s crucial for businesses and organizations to understand both the strengths and limitations of the technology. AI is incredibly powerful for tasks like data analysis, automation, and language generation, but when it comes to reasoning and problem-solving, human oversight is still essential.

Here are a few key considerations for organizations:

1. Human-in-the-loop systems: For tasks that require critical thinking, reasoning, or decision-making, organizations should ensure there is still human oversight. AI can assist in providing recommendations, but humans should make the final call.

2. AI for specific use cases: While AI struggles with some tasks, it excels in others. Businesses should deploy AI in areas where it has proven strengths, such as predictive analytics, pattern recognition, and language processing.

3. Continuous evaluation of AI models: As the study highlights, AI models can make mistakes when presented with new or unfamiliar information. Regularly testing and improving these models can help ensure better performance.

Critical Questions for LinkedIn Readers:

• Can AI truly reason, or are we overestimating its capabilities?
• How should businesses balance AI’s strengths with its limitations in critical decision-making processes?
• What steps can be taken to improve AI’s ability to handle reasoning tasks more effectively?

Final Thoughts: The Limitations of AI Reasoning

As AI becomes a more prominent tool in industries worldwide, it’s essential to recognize its limitations. While AI can perform impressive tasks, such as language generation, image recognition, and data analysis, it falls short in areas that require logical reasoning and critical thinking.

This recent study reminds us that we are still far from creating AI that can think and reason as humans do. Instead, AI relies on patterns and data, sometimes stumbling over trivial details that a human would easily ignore. As businesses and researchers continue to explore the potential of AI, we must keep in mind that human oversight and judgment are still vital.

• Do you think we are closer to building AI that can reason like humans, or are we still far from that goal?
