A new report suggests increasing the U.S. nuclear arsenal could lead to more nuclear crises, as adversaries may feel less deterred. The study highlights the importance of enhancing survivability and resilience over expanding the arsenal, with a focus on strengthening nuclear submarine capabilities and defending against cyberattacks.
Researchers at the University of Arizona assessed seven generative AI models for fallibility, persuadability and correctability during lengthy conversations. The study revealed intrinsic limitations of these models, including oscillation between accepting and rejecting false statements, and the need for careful human engagement to miti...
A team of researchers at UCL has identified key brain regions essential for logical thinking and problem-solving. They used lesion-deficit mapping to study patients with brain lesions caused by stroke or tumors and found that damage to the right frontal lobe impaired reasoning skills.
Researchers propose future data collection and processing principles to address issues in data accumulation, modeling, and application. A global standard protocol framework is needed for a high-quality data ecosystem and healthy AI development.
Large language models (LMs) exhibit human-like reasoning flaws, particularly in tasks requiring semantic content and believability. LMs struggle to distinguish between valid and invalid arguments, mirroring human errors, especially when semantic content is sensical and believable.
A University of Córdoba team developed an algorithm that predicts student performance in online education, dividing students into four categories and providing personalized assistance. The algorithm uses ordinal classification and fuzzy logic to make more accurate predictions than previous models.
A nine-year study led by Kyoto University found that critical thinking and logical decision-making promoted intelligent attitudes and risk literacy, reducing anxiety and food avoidance among citizens in Tokyo and Kansai regions.
Researchers found that rats, like humans, tend to overestimate the likelihood of two events occurring together. This study suggests a shared cognitive mechanism between humans and animals, which could have implications for understanding psychopathological conditions.
A new study found evidence of a reverse 'Flynn effect' in the US, with declines in verbal reasoning, matrix reasoning, and letter/number series scores, but an increase in 3D rotation scores. The study suggests that changing values and motivation may be contributing factors.
A simulated crisis-care event revealed the moral distress experienced by triage team members who had to prioritize patients for scarce resources. The study aimed to operationalize a process for making life-and-death patient decisions, but triage-team members struggled with balancing individual patient needs with fair resource allocation.
A new study explores ideological belief bias, where people judge logical arguments based on their believability rather than sound premises. Liberals and conservatives showed varying levels of ability to identify flawed arguments supporting opposing views. The findings suggest that being open to the other side can lead to a better under...
A study by UC Berkeley researchers found that tracking students' eye movements can reveal more about their understanding of complex material than neuroimaging technology. By analyzing ocular activity, the team detected improvements in reasoning skills after intensive practice for the logic games section of the LSAT.
A new study published in Personality and Individual Differences found that high cognitive ability is not a safeguard against believing in conspiracy theories and paranormal phenomena. People with strong motivation to form rational beliefs can still fall prey to these unfounded ideas.
A new report from psychologists suggests that people can come to see a reliance on reason and evidence as a moral issue, leading to harsher judgments of those perceived as less rational. Individuals who moralize rationality view others as less moral and prefer to distance themselves.
Researchers from Harvard University found that Resident Registration Numbers in South Korea can be easily decrypted using computation and logical reasoning. The study reveals vulnerabilities in the encoding system, compromising individual privacy and urging a more robust redesign.
The article highlights the need for a national 'Mental Health Pathway' to enable paramedics to provide appropriate care for patients with mental health issues. The proposed pathway aims to reduce admissions and re-attendance while improving care for patients.
A study published in CMAJ found that people who smoke contraband cigarettes are less likely to stop smoking compared to those who smoke premium or discount cigarettes. Contraband cigarettes are widely available and significantly cheaper than legitimate options.
In a groundbreaking experiment, researchers found that fish can use transitive inference to understand their place in the pecking order. By observing rival males fight and watching which rival they spent more time near, bystander fish could infer their relative strength and navigate social hierarchies.
