AI1 picks up racial and gender biases2 when learning language from text, researchers say. Without any supervision, a machine learning algorithm learns to associate female names more with family words than career words, and black names as being more unpleasant than white names.

For a study published today in Science, researchers tested the bias of a common AI model, and then matched the results against a well-known psychological test that measures bias in humans. The team replicated in the algorithm all the psychological biases they tested, according to a study from co-author Aylin Caliskan, a post-doc at Princeton University. Because machine learning algorithms are so common, influencing everything from translation to scanning names on resumes, this research shows that the biases are pervasive, too. 

An algorithm is a set of instructions that humans write to help computers learn. Think of it like a recipe, says Zachary Lipton, an AI researcher at UC San Diego who was not involved in the study. Because algorithms use existing materials — like books or text on the internet — it’s obvious that AI can pick up biases if the materials themselves are biased. (For example, Google Photos tagged black users as gorillas.) We’ve known for a while, for instance, that language algorithms learn to associate the word “man” with “professor” and the word “woman” with “assistant professor.” But this paper is interesting because it incorporates previous work done in psychology on human biases, Lipton says.

For today’s study, Caliskan’s team created a test that resembles the Implicit Association Test (IAT), which is commonly used in psychology to measure how biased people are (though there has been some controversy over its accuracy). In the IAT, subjects are presented with two images — say, a white man and a black man — and words like “pleasant” or “unpleasant.” The IAT calculates how quickly you match up “white man” and “pleasant” versus “black man” and “pleasant,” and vice versa. The idea is that the longer it takes you to match up two concepts, the more trouble you have associating them.

The test developed by the researchers also calculates bias, but instead of measuring “response time”, it measures the mathematical distance between two words. In other words, if there’s a bigger numerical distance between a black name and the concept of “pleasant” than a white name and “pleasant”, the model’s association between the two isn’t as strong. The further apart the words are, the less the algorithm associates them together.

Caliskan’s team then tested their method on one particular algorithm: Global Vectors for Word Representation (GLoVe) from Stanford University. GLoVe basically crawls the web to find data and learns associations between billions of words. The researchers found that, in GLoVe, female words are more associated with arts than with math or science, and black names are seen as more unpleasant than white names. That doesn’t mean there’s anything wrong with the AI system, per se, or how the AI is learning — there’s something wrong with the material.

Why does Artificial Intelligence (AI) pick up biases?

A schematic summary would say as follows: At a founding time, romantic fiction saw the peculiarities of the Brazilian family life under the picturesque and the national identity signs, over which it laid some more or less feuilletonist fabling. The combination, in line with the needs of the young country, was very successful. Although irreverent, the emphasis on mirroring and its somewhat regressive accomplice character formed a positive sign on our particular traits. One generation later, Machado used in a different manner the same thematic, ideological, and aesthetic complexity, this time without the covering mists of local color and patriotic self-congratulation. The large Brazilian family was now observed from the point of view of the enlightened dependent, who was part of it and transformed it into a problem. This is a special system of relationships, with its own structure, resources and problems, which needed to be analyzed. Its difference was a sign of primitiveness, because the tacit measure of the dependent was the Rights of Man, which were effective, in principle, in other regions. The narrator’s fondness shifted to the heroine’s struggles against injustice, which was also portrayed in a feuilletonist fashion. As for the opposing side, it was inevitable that the conflict arrangement, as it developed from book to book, made more visible the negative traits of the landowner. These traits absorbed and reflected precisely, as a fault, the absurd lack of balance between the classes. Using the consequences of this very lack of balance, which gave no signs of internal regeneration, Machado invented the formula that would characterize his mature works and make him a great writer. He did not surrender to the easy delights of romantic picturesqueness. Likewise, he now renounced the unanimous fondness towards the moderate narrator and his good causes.

The new artistic device dealt indirectly with dependents’ frustrations and directly with their abandonment by landowners – the peripheral society incapable of integration resonated. The scope of the formal arrangement, which challenged the secular spirit’s superstitions, especially the trust in progress and in benevolence, is uncomfortable to this day. The insinuating personification of an elite narrator enviably civilized and deeply involved in oppressive relationships, which he arranges and judges himself, is a chess move that disarranges the narrative board, making the game more real. The process challenges readers in every line: it teaches them to think by themselves; to discuss not only the issues, but also their presentation; to consider the narrators and authorities – always the interested party – from a distance, even if they are eloquent; to doubt the civilizing and national commitment of the privileged, particularly in young countries, where this intention plays a major role; to feel an aversion to the imaginary consolations of romanticism, manipulated by the narrative authority to its own benefit. The process teaches, above all, that the combination of the cosmopolitan and the excluded spheres may be stable, without a feasible solution. This demonstration is a juicy one because it illustrates and examines the nation’s “delicious” mechanisms – to use the Machadian term – of the non-bourgeois reproduction of the bourgeois order. However, the demonstration is also universal to some extent, because globally, unlike what it seems, this reproduction is the rule, not the exception.

The heroines of the first novels are not very interesting because their precarious social status is distorted by the romantic cliché. Their vicissitudes, however, stress the antagonistic class traits, whose figure has literary originality. In the novels of the second phase, once the angle is inverted, it is the poor who appear in the subjective mirror of owners, where the prisms are either that of bourgeois individualism or of paternalistic domination, according to the selfish convenience impudence. The dependent becomes extraordinarily relevant in that light. They are portraits of the powerless that get no recognition for the value of work, no rights protected, and no compensation by divine providence. It is the social vacuum generated by modern slavery to freedom without possessions, another issue that, mutatis mutandis, lives on.

In the same line of advanced resonance of the primitiveness, notice how the extra bourgeois aspect of local issues works, and also the narrative relationship itself: at times it is only a shift in the rule; at times it is a movement in its own right, which escapes the dominating definitions and discovers unknown land. To give an idea, compare the part of authority in the definition and dissolution of characters, themselves or others; the relationships between personal separation and the experience of time, between command and insanity – often by the ones in charge; the extra scientific dimensions of science, with its authoritarian and sadistic roles; the overall difference that generates a point of view, etc. In this manner, Machadian fiction and the advanced literature of his time converged – both tried to release other realities under the bourgeois reality. As a mere indication, it is worth mentioning a few similarities, rather at random, in the innovative field, such as Dostoievski, Baudelaire, Henry James, Tchekov, Proust, Kafka, and Borges. Machado’s classical derivations are countless and have led critics to find his merit there, which hinders the understanding of the up-todateness and advanced character of his experimentation.

    For over 35 years, Rush University Medical Center in Chicago, in United States of America, has been helping infant patients and their families through a volunteer cuddler program.

    When families are away from the hospital’s neonatal intensive care unit (NICU), volunteers comfort infants with cuddles. Families can’t be in the hospital all the time, but the babies had needs after they left. The staff understood these needs and volunteer cuddlers helped. A lot of the volunteers are parents whose children were in the NICU before. After undergoing extensive training, they are using their experiences and skills to provide other parents a sense of relief and security.

    Studies show that interactions like holding, rocking, singing, reading and talking to the infants reduce stress and pain, and they improve their overall physical health.

    Recent research suggests that about one in seven life-threatening allergic reactions are caused by foods not currently listed on mandatory allergen labels.

    Food allergies are rising, yet regulations, such as the European Union’s 14-item allergen list from 2011, have not been updated in years.

   To identify overlooked triggers, Dominique Sabouraud-Leclerc and colleagues analyzed 2999 cases of food-induced anaphylaxis reported between 2002 and 2023 to the Allergy-Vigilance Network. They found that goat or sheep milk, buckwheat, peas, lentils, pine nuts, kiwi, apples, beehive products and alpha-gal (a sugar that can trigger an allergy to red meat and other mammalian products) were responsible for about 14% of reactions. Goat and sheep cheese caused particularly severe outcomes, including two deaths, and hidden exposures in processed foods increased risks.

      Based on these findings, the researchers recommend adding goat and sheep milk products, peas, lentils, buckwheat and pine nuts to Europe’s mandatory allergen labelling. They argue that clearer information is crucial for protecting allergic individuals and could inspire broader international policy updates.

Who's driving? Autonomous cars may be entering the most dangerous phase

    Autopilot controls are not yet fully capable of functioning without human intervention – but they’re good enough to lull us into a false sense of security.
    When California police officers approached a Tesla stopped in the centre of a five-lane highway outside San Francisco last week, they found a man asleep at the wheel. The driver, who was arrested on suspicion of drunk driving, told them his car was in “autopilot”, Tesla’s semi-autonomous driver assist system.
    In a separate incident, firefighters in Culver City reported that a Tesla vehicle parked at the rear of their fire truck as it attended an accident on the freeway. Again, the driver said the vehicle was in autopilot.

    The oft-repeated promise of driverless technology is that it will make the roads safer by reducing human error, the primary cause of accidents. However, those vehicles have a long way to go before they can eliminate the drivers. 

    However, research has shown that drivers get lulled into a false sense of security to the point where their minds and gazes start to wander away from the road. People become distracted or preoccupied with their smartphones. So when the car encounters a situation where the human needs to intervene, the driver can be slow to react.

    During tests the IIHS recorded a Mercedes having problems when the lane on the highway forked in two. The radar system locked onto the right-hand exit lane when the driver was trying to go straight.

    Concern over this new type of distracted driving is forcing engineers to introduce additional safety features to compensate. For example, GM has introduced eye-tracking technology to check the driver’s eyes are on the road while Tesla drivers can be locked out of autopilot if they ignore warnings to keep their hands on the steering wheel.

     In spite of these problems, Tesla’s CEO, Elon Musk, remains bullish about his company’s autonomous technology, even suggesting that by 2019 drivers would be able to sleep in their cars – presumably without being arrested by highway patrol officers.
