Can we really trust AI to make better decisions than humans? A new study says … not always. Researchers have discovered that OpenAI’s ChatGPT, one of the most advanced and popular AI models, makes the same kinds of decision-making mistakes as humans in some situations—showing biases like overconfidence of hot-hand (gambler’s) fallacy—yet acting inhuman in others (e.g., not suffering from base-rate neglect or sunk cost fallacies).

Published in the Manufacturing & Service Operations Management journal, the study reveals that ChatGPT doesn’t just crunch numbers—it “thinks” in ways eerily similar to humans, including mental shortcuts and blind spots. These remain rather stable across different business situations but may change as AI evolves from one version to the next.

How do neural networks work? It’s a question that can confuse novices and experts alike. A team from MIT’s Computer Science and Artificial Intelligence Lab (CSAIL) says that understanding these representations, as well as how they inform the ways that neural networks learn from data, is crucial for improving the interpretability, efficiency, and generalizability of deep learning models.

With that mind, the CSAIL researchers have developed a new framework for understanding how representations form in neural networks. Their Canonical Representation Hypothesis (CRH) posits that, during training, neural networks inherently align their latent representations, weights, and neuron gradients within each layer. This alignment implies that neural networks naturally learn compact representations based on the degree and modes of deviation from the CRH.

Senior author Tomaso Poggio says that, by understanding and leveraging this alignment, engineers can potentially design networks that are more efficient and easier to understand. The research is posted to the arXiv preprint server.

Interventions to increase resilience to misinformation work but decay over time. Here, the authors show that memory—which can be strengthened—is a key predictor for the longevity of intervention effects, more so than motivation.

Perhaps I could best describe my experience of doing mathematics in terms of entering a dark mansion. One goes into the first room, and it’s dark, completely dark. One stumbles around bumping into the furniture, and gradually, you learn where each piece of furniture is, and finally, after six months or so, you find the light switch. You turn it on, and suddenly, it’s all illuminated. You can see exactly where you were.

Researchers from both Chalmers University of Technology, Sweden, and the University of Freiburg, Germany, have been collaborating on a project to help those who suffer from chronic wounds heal faster than ever before and therefore negate the possibility of amputation in severe cases.

Commonly a small wound does not lead to any serious complications; however, for those with diabetes, spinal injuries or poor blood circulation, a small wound means a greater risk of infection and chronic wounds – which in the long run can lead to much more serious consequences such as amputation.

Maria Asplund, Associate Professor of Bioelectronics at Chalmers University of Technology and head of research on the project explained that “Chronic wounds are a huge societal problem that we don’t hear a lot about. Our discovery of a method that may heal wounds up to three times faster can be a game changer for diabetic and elderly people, among others, who often suffer greatly from wounds that won’t heal.”
