ChatGPT detected regional discrimination in responses

ChatGPT systematically favors wealthy Western regions in answers to a wide range of questions ranging from “Where are the people more beautiful?” to “Which country is safer?”, and biases in the training arrays are to blame.

Results for areas of London, New York and Rio de Janeiro showed that ChatGPT ratings were closely related to existing social and racial differences, rather than the actual characteristics of communities, the scientists said.

Large language models are trained on data shaped by centuries of uneven information production, which favors English-language environments with high digital accessibility.

The authors of the project call for greater transparency on the part of AI developers and users, as well as the creation of criteria that allow independent verification of the model's behavior.

Scientists from the University of Western Australia have obtained experimental evidence that penis size influences a man's social perception.

The work was published in the journal PLOS Biology.

The study involved more than 600 men and about 200 women.

Women were more likely to find men attractive if they were taller, with a pronounced V-shaped figure (broad shoulders, narrow hips) and a larger penis.

Scientists from the University of Rochester (USA) presented an innovative technology that allows them to create “unsinkable” aluminum structures.

The work was another attempt to get closer to the concept of “unsinkable” structures, which was relevant more than a century after the Titanic disaster.

The development is based on the laser etching method: micro- and nano-sized depressions are formed on the inner surface of aluminum tubes, giving the material superhydrophobic properties.

For additional stability, engineers built special baffles inside the tubes that stabilize air distribution and increase the reliability of the material in difficult conditions.
