AI’s Human Side: How ChatGPT Mirrors Our Thinking Flaws and What It Means for Decision-Making

Artificial intelligence (AI) is transforming industries, streamlining processes, and reshaping how we make decisions. From hiring employees to approving loans, AI systems like OpenAI’s ChatGPT are increasingly entrusted with high-stakes choices. But a groundbreaking study reveals something surprising: ChatGPT doesn’t just process data—it sometimes thinks like a human, complete with the same judgment errors and cognitive biases we’re prone to. This discovery raises critical questions about how much we can trust AI to make better decisions than humans and what steps we need to take to ensure it doesn’t amplify our flaws.

In this in-depth exploration, we’ll dive into the study’s findings, unpack what it means for businesses and policymakers, and discuss how we can harness AI’s potential while addressing its human-like limitations. Let’s explore why ChatGPT’s decision-making quirks matter and how they could shape the future of AI.

The Study: AI with a Human Touch

Published in the INFORMS journal Manufacturing & Service Operations Management, the study examined how ChatGPT performs in decision-making scenarios, focusing on whether it exhibits cognitive biases—mental shortcuts that often lead humans to flawed conclusions. Researchers put ChatGPT through 18 rigorous tests designed to detect biases commonly seen in human thinking, such as overconfidence, the hot-hand fallacy (believing a streak will continue), and the conjunction fallacy (misjudging probabilities based on specific details).

The results were eye-opening:

AI Falling Into Human Traps: ChatGPT showed biases such as ambiguity aversion, overconfidence, and the conjunction fallacy (sometimes called the “Linda problem,” when people overestimate the possibility of particular events) in over half of the tests. For example, the AI sometimes assumed it was more accurate than it actually was or favored options with clearer information, even if less certain options might have been better.

Math Whiz, Judgment Novice: ChatGPT excelled at logical and probability-based tasks, outperforming humans in calculations and formula-driven problems. However, it struggled with subjective judgment calls, where context and nuance matter more than raw data.

Bias Persists Across Models: The study compared ChatGPT’s older GPT-3.5 model with the newer GPT-4. While GPT-4 was more analytically accurate, it sometimes showed stronger biases in judgment-based tasks, suggesting that advancements don’t automatically eliminate flawed thinking.

These findings challenge the assumption that AI is a purely objective tool. Instead, ChatGPT appears to mirror aspects of human cognition, including the mental shortcuts and systematic errors that lead to biased decisions.

Why Does AI Think Like Us?

AI systems like ChatGPT are trained on vast datasets drawn from human-generated content—everything from books and articles to social media posts and websites. This data shapes how the AI interprets information and makes decisions. “As AI learns from human data, it may also think like a human—biases and all,” says Yang Chen, the study’s lead author and an assistant professor at Western University.

Here’s how ChatGPT’s human-like tendencies showed up in the study:

Risk-Averse Choices: ChatGPT often played it safe, avoiding risky options even when they had the potential for better outcomes. This mirrors human tendencies to prioritize certainty over uncertainty, even when the data suggests otherwise.

Overconfidence: The AI sometimes overestimated its accuracy, assuming its answers were more reliable than they actually were. This is similar to how humans can be overly certain of their judgments, even when evidence is lacking.
Confirmation Bias: ChatGPT showed a preference for information that aligned with its existing assumptions, rather than seeking out contradictory evidence. This tendency can reinforce flawed conclusions, just as it does in human decision-making.
Avoiding Ambiguity: When faced with unclear or incomplete information, the AI leaned toward options with more certain outcomes, even if they weren’t optimal. Humans often make the same choice, shying away from ambiguity in favor of familiarity.

Interestingly, ChatGPT didn’t fall for every human bias. For example, it avoided *base-rate neglect* (ignoring general probabilities in favor of specific details) and the *sunk-cost fallacy* (continuing a failing endeavor because of past investments). This suggests that while AI can mimic human thinking in some areas, it diverges in others, creating a complex blend of strengths and weaknesses.

The Implications: Can We Trust AI with Big Decisions?

AI is already embedded in critical decision-making processes across industries. Businesses use it to screen job applicants, banks rely on it to evaluate loan applications, and governments explore its potential for policy analysis. But if AI mirrors human biases, could it inadvertently perpetuate flawed decisions instead of improving them?

The Risks of Biased AI

The study highlights a sobering reality: AI isn’t a neutral referee. “If left unchecked, it might not fix decision-making problems—it could actually make them worse,” says Samuel Kirshner of UNSW Business School. For instance:

Reinforcing Inequities: If AI favors certain candidates or loan applicants due to biased training data, it could deepen existing inequalities rather than eliminate them.
Amplifying Errors: In high-stakes contexts like healthcare or criminal justice, biased AI could lead to incorrect diagnoses or unfair sentencing, with far-reaching consequences.
Undermining Trust: If businesses or governments rely on AI without recognizing its flaws, they risk eroding public confidence when errors come to light.

As Queen’s University’s Anton Ovchinnikov puts it, “AI is better than most people at figuring out the proper formula when a decision has an obvious right answer. However, AI might make the same mistakes in thinking as humans when it comes to making decisions.

The Need for Oversight

The researchers emphasize that AI should be treated like any human decision-maker: with oversight and accountability. “AI should be treated like an employee who makes important decisions—it needs oversight and ethical guidelines,” contends Meena Andiappan of McMaster University. If not, we run the risk of automating faulty reasoning rather than enhancing it.

This call for oversight comes at a critical time. Governments worldwide are drafting AI regulations to balance innovation with safety. The study underscores the urgency of ensuring these regulations address bias and promote transparency in AI-driven decisions.

What’s Next for AI?

The study’s findings don’t mean AI is doomed to repeat human errors forever. Instead, they point to opportunities for improvement. Here are some key steps businesses, developers, and policymakers can take to make AI a more reliable decision-maker:

1. Regular Audits

Just as companies audit financial records or employee performance, they should regularly evaluate AI systems for bias. This involves testing how AI performs in real-world scenarios and identifying patterns of flawed judgment. Tracy Jenkin of Queen’s University notes, “Managers must evaluate how different models perform on their decision-making use cases and regularly re-evaluate to avoid surprises.”

2. Refining Models

AI developers can use insights from studies like this to refine their models. For example, by adjusting training data or algorithms, they can reduce tendencies like overconfidence or risk aversion. The evolution from GPT-3.5 to GPT-4 shows progress in some areas, but also highlights that new biases can emerge as models advance.

3. Ethical Guidelines

Businesses and governments should establish clear ethical standards for AI use. This includes defining when AI is appropriate for decision-making and when human judgment should take precedence. Guidelines should also mandate transparency, so users understand how AI reaches its conclusions.

4. Human-AI Collaboration

Rather than relying solely on AI, organizations can combine its strengths with human expertise. AI excels at crunching numbers and spotting patterns, while humans are better at navigating nuance and context. A collaborative approach can mitigate biases and improve outcomes.

The Bigger Picture: The Future of AI

The discovery that ChatGPT thinks like a human—flaws and all—is both fascinating and cautionary. It reminds us that AI is a reflection of the data it’s trained on, which is inherently shaped by human perspectives, priorities, and mistakes. As AI’s influence grows, ensuring it enhances decision-making rather than replicating our shortcomings will be crucial.

This study is a wake-up call for anyone who views AI as a cure-all for human error. Although it’s a strong tool, it’s not perfect. By acknowledging its limitations and taking proactive steps to address them, we can harness AI’s potential to drive progress while minimizing its risks.

Key Takeaways

AI Mimics Human Biases: ChatGPT exhibits cognitive biases like overconfidence, risk aversion, and confirmation bias, making it less objective than we might assume.
Strengths and Weaknesses: While AI excels at logical and mathematical tasks, it struggles with subjective judgment, where biases are more likely to surface.
Oversight is Essential: Businesses and policymakers must monitor AI decisions closely, treating it like a human employee with accountability and ethical guidelines.
Continuous Improvement: Regular audits, model refinements, and human-AI collaboration can help reduce biases and improve decision-making.

As we navigate the AI-driven future, studies like this one remind us to approach technology with curiosity, caution, and a commitment to doing better. By understanding AI’s human-like quirks, we can build systems that not only mirror our strengths but also rise above our flaws.
