AI chatbots provide less-accurate information to vulnerable users, study shows

Large language models (LLMs) have been championed as tools that could democratize access to information worldwide, offering knowledge in a user-friendly interface regardless of a person’s background or location. However, new research from MIT’s Center for Constructive Communication (CCC) suggests these artificial intelligence systems may actually perform worse for the very users who could most …

Most AI bots lack basic safety disclosures, study finds

Many people use AI chatbots to plan meals and write emails, AI-enhanced web browsers to book travel and buy tickets, and workplace AI to generate invoices and performance reports. However, a new study of the “AI agent ecosystem” suggests that as these AI bots rapidly become part of everyday life, basic safety disclosure is “dangerously …

Laughter reveals how we use AI at home

Voice assistants such as Alexa are often marketed as smart tools that streamline everyday life. But once the technology moves into people’s homes, interest quickly fades. This is shown by new research in which laughter is used as a key to understanding how people actually use—and understand—artificial intelligence in everyday life. The paper is published …

Can AI build a machine that draws a heart? What automated mechanism design could mean for mechanical engineering

Can you design a mechanism that will trace out the shape of a heart? How about the shape of a moon, or a star? Mechanism design—the art of assembling linkages and joints to create machines with prescribed motion—is one of the quintessential activities of mechanical engineers, but has resisted automation for almost two centuries.

Why AI may overcomplicate answers: Humans and LLMs show ‘addition bias,’ often choosing extra steps over subtraction

When making decisions and judgments, humans can fall into common “traps,” known as cognitive biases. A cognitive bias is essentially the tendency to process information in a specific way or follow a systematic pattern. One widely documented cognitive bias is the so-called addition bias, the tendency of people to prefer solving problems by adding elements …
