As artificial intelligence becomes more commonplace in professional settings, human oversight is often promoted as a safeguard against automated mistakes. New research published in PNAS Nexus Our results suggest that human experts are significantly more likely to mistakenly accept a harsh decision if they believe that the decision was made by an artificial intelligence system rather than a human colleague. This pattern provides evidence that relying on human reviews to spot algorithmic errors may not be as effective as many expect. Study author Rigissa Megalokonomo, associate professor of economics at Monash University, was drawn to this issue by the rapid…
The way people choose potential romantic partners may rely on the same mental decision-making system used for many other types of choices, according to a recent study. The study found that a computational model accurately predicted both who people chose as potential partners and how quickly they made that decision. This research cognitive science. Researchers have been trying to understand what drives romantic attraction for decades. Scientists have learned a lot about what characteristics people like and what characteristics are deal-breakers, but they know less about the mental processes that combine those preferences to make the final decision. The current…

A recent study found that the degree to which a person has autistic traits is related to how their brain processes social rewards compared to non-social rewards. The researchers found that poor connectivity between certain brain regions helps explain why people with more autistic traits often show no behavioral preference for social imagery. These findings show that personality neuroscience. Daily life is full of rewards that shape human behavior. There are also purely physical or material rewards, such as a delicious cake or finding money on the street. Other rewards can be social, such as a warm smile from a…
Recent research published in International Journal of Psychology provide evidence that insecure attachment styles tend to be associated with a larger number of children. This research suggests that cultural norms play an important role in how our deeply ingrained relationship habits influence family size. These findings question the assumption that a secure attachment style is always the most beneficial trait for reproductive success. Attachment theory explains how early interactions with caregivers shape how people relate to others throughout their lives. According to this framework, individuals develop pragmatic models of themselves and others that guide their expectations in romantic partnerships and…
Last week, those trying to squeeze in a productive day’s work in the searing heat of southern England had little doubt about the effects of extreme weather.But the economic impact of the climate crisis in the UK is not limited to the many hours lost in a quiet sweat or getting children out of the scorching classroom early.Two well-timed interventions last week by financial lobby group TheCityUK and Swati Dhingra, an economist and independent member of the Bank of England’s Monetary Policy Committee, drove home that point.Both men pointed to the need for the government to play a more active…
Hawaii faces a growing plastic waste challenge. Recycling on the islands is expensive and difficult, and large amounts of marine debris continue to wash ashore or remain in surrounding waters. Researchers are now exploring innovative solutions to turn discarded fishing nets and household plastic waste into asphalt for roads. Initial results suggest this approach could provide a practical new destination for plastics that would otherwise end up in landfills or oceans. Jeremy Axworthy, a researcher at Hawaii Pacific University’s Center for Marine Debris Research (CMDR), presented the findings at the American Chemical Society (ACS) Spring Meeting. “This study investigates whether…
Supereruptions are one of the most powerful volcanic phenomena on Earth. These large eruptions can release more than 1,000 cubic kilometers of magma, rock, and ash, with dramatic impacts on climate, ecosystems, and human societies. Because of their impact, scientists are working to better understand the underground processes that create and sustain these giant volcanoes. Researchers at the Institute of Geology and Geophysics, Chinese Academy of Sciences (IGGCAS) have recently developed a detailed three-dimensional model of western North America that simulates the current behavior of the lithosphere and underlying mantle. Their research revealed a new explanation for how magma is…
Long-term research has found that even occasional visits from mountain lions can rebuild entire ecosystems. Researchers studying a small suburban preserve about 45 miles south of San Francisco found that as mountain lion activity increased, the behavior of many other animals changed as well. The impact extended beyond wildlife, affecting plant growth and the overall health of the landscape. mountain lion (puma conqueror) began to appear frequently on trail cameras at Stamford’s Jasper Ridge Biological Preserve (‘Auchamin’ Auyakuma) from 2015 to 2020. Researchers observed a decline in deer activity during the same period compared to earlier periods when mountain lions…
Teenagers who use cannabis may be more likely to develop serious mental illness by young adulthood, according to a major new study published in . JAMA Health Forum. Researchers followed 463,396 adolescents between the ages of 13 and 17 to 26. Teens who reported using cannabis within the previous year were found to have a significantly higher risk of developing psychotic disorders, bipolar disorder, depression, and anxiety disorders later in life. Among adolescents who used cannabis, the risk of both psychotic disorders and bipolar disorder approximately doubled. The study was conducted by researchers at Kaiser Permanente, the Public Health Institute’s…
