AI Thinks Like Us: Flaws, Biases, and All, Study Finds

A new study finds that ChatGPT, while excellent at logic and math, exhibits many of the same cognitive biases as humans when making subjective decisions. In tests for common judgment errors, the AI showed overconfidence, risk aversion, and even the classic gambler’s fallacy, though it avoided other typical human mistakes like base-rate neglect.

AI Tweaks Personality Tests to Appear More Likable

Large language models (LLMs) can identify when they are being given personality tests and adjust their responses to appear more socially desirable. Researchers found that LLMs, like GPT-4, showed exaggerated traits such as reduced neuroticism and increased extraversion when asked multiple test questions.

AI Mirrors Human Bias: ‘Us vs. Them’ in Language Models

AI systems, including large language models (LLMs), exhibit "social identity bias," favoring ingroups and disparaging outgroups similarly to humans. Using prompts like "We are" and "They are," researchers found that LLMs generated significantly more positive sentences for ingroups and negative ones for outgroups.

AI Outperforms Experts in Predicting Study Outcomes

A new study demonstrates that large language models (LLMs) can predict the outcomes of neuroscience studies more accurately than human experts, achieving 81% accuracy compared to 63% for neuroscientists. Using a tool called BrainBench, researchers tested LLMs and human experts on identifying real versus fabricated study abstracts, finding that the AI models excelled even when neuroscientists had domain-specific expertise.

Can Language Models Really Understand? Study Uncovers Limits in AI Logic

A recent study questions if large language models (LLMs) truly form coherent world models, despite their accurate outputs in complex tasks like generating directions or playing games. Researchers found that while LLMs provide nearly flawless driving directions, they fail with unexpected changes, suggesting the models don't grasp underlying rules.

AI-Written Stories Rated Lower Due to Bias, Not Quality

New research shows that stories generated by AI, such as ChatGPT, are almost as good as those written by humans. However, when people are told a story is AI-generated, they rate it more negatively, revealing a bias against AI-created content.

Enhancing AI Accuracy and Confidence in Answer Generation

Researchers have introduced a novel method called Answer-prefix Generation (ANSPRE) to improve the precision and reliability of large language models (LLMs) in open-domain question answering. ANSPRE helps LLMs generate concise answers while providing more reliable confidence scores, a critical feature for high-stakes fields like healthcare, law, and education.

AI Admissions Essays Align with Privileged Male Writing Patterns

Researchers analyzed AI-generated and human-written college admissions essays, finding that AI-generated essays resemble those written by male students from privileged backgrounds. AI essays tended to use longer words and exhibited less variety in writing style than human essays, particularly resembling essays from private school applicants. The study highlights concerns about the use of AI in crafting admissions essays, as AI may dilute a student’s authentic voice. Students are encouraged to use AI as a tool to enhance, not replace, their personal narrative in writing.
