How AI is Reshaping Human Thought and Decision-Making

A new study introduces "System 0," a cognitive framework where artificial intelligence (AI) enhances human thinking by processing vast data, complementing our natural intuition (System 1) and analytical thinking (System 2). However, this external thinking system poses risks, such as over-reliance on AI and a potential loss of cognitive autonomy.

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.

AI Uncovers DNA Variants Linked to Psychiatric Disorders

Researchers developed an AI algorithm, ARC-SV, to detect complex structural variants in the human genome that previous methods missed. Analyzing over 4,000 genomes, researchers discovered thousands of complex variants, many affecting brain-related genes and linked to schizophrenia and bipolar disorder.

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.

People Empathize with Bullied AI Bots

People empathize with AI bots excluded from a virtual game, treating them like social beings in need of fairness. Participants favored giving the AI bot a fair chance in play, with older adults showing a stronger inclination to rectify the perceived unfairness.

Vulnerability Found in AI Image Recognition

A new study reveals a vulnerability in AI image recognition systems due to their exclusion of the alpha channel, which controls image transparency. Researchers developed "AlphaDog," an attack method that manipulates transparency in images, allowing hackers to distort visuals like road signs or medical scans in ways undetectable by AI. Tested across 100 AI models, AlphaDog exploits this transparency flaw, posing significant risks to road safety and healthcare diagnostics.

AI-Enhanced MRIs Show Potential for Brain Abnormality Detection

Researchers have developed a machine learning model that upgrades 3T MRI images to mimic the higher-resolution 7T MRI, providing enhanced detail for detecting brain abnormalities. The synthetic 7T images reveal finer features, such as white matter lesions and subcortical microbleeds, which are often difficult to see with standard MRI systems. This AI-driven approach could improve diagnostic accuracy for conditions like traumatic brain injury (TBI) and multiple sclerosis (MS), though clinical validation is needed before wider use.

Integrating Machine Learning Boosts Disease Prediction Accuracy

A recent review explored how integrating machine learning with traditional statistical models can enhance disease risk prediction accuracy, a key tool in clinical decision-making. While traditional models like logistic regression are limited by certain assumptions, machine learning offers flexibility but has inconsistent results in some cases. The study revealed that combined models, especially stacking methods, outperform individual methods by harnessing each approach’s strengths and addressing their weaknesses.

From Face to Feeling: Context Shapes Emotion Recognition

Emotion recognition extends far beyond facial expressions, involving a rich interplay of context, physical attributes, and background knowledge. Researchers propose that recognizing emotion is part of forming an overall impression of a person, shaped by cues like clothing, perceived social roles, and personal history. For instance, a facial expression of fear might be interpreted as anger if background context suggests it.

Can AI Tackle Abstract Reasoning? Study Tests Cognitive Limits

Researchers tested artificial intelligence’s ability to solve abstract visual puzzles similar to human IQ tests, revealing gaps in AI’s reasoning skills. Open-source AI models struggled, while closed-source models like GPT-4V performed better, but far from perfectly.

Electronic Tongue Uses AI to Detect Differences in Liquids

Researchers have developed an AI-powered "electronic tongue" capable of distinguishing subtle differences in liquids, such as milk freshness, soda types, and coffee blends. By analyzing sensor data through a neural network, the device achieved over 95% accuracy in identifying liquid quality, authenticity, and potential safety issues. Interestingly, when the AI was allowed to select its own analysis parameters, it outperformed human-defined settings, showing how it holistically assessed subtle data.
