A study found that young adults tend to consider both risks and benefits in their sexual behavior, making consistent and thoughtful decisions. The research suggests that even those prone to heuristic decision-making become rational when faced with similar choices framed as sexual decisions.
A study published in CHI 2020 found that users are influenced by contextual cues to disclose personal information, including social security numbers and phone numbers. The researchers identified 12 heuristics, or mental shortcuts, that trigger this behavior, such as the bandwagon heuristic and authority cue.
A team of researchers from MIT has developed an algorithm to solve hard combinatorial problems using optical machines. This breakthrough has the potential to revolutionize fields such as biology, drug discovery, and routing/scheduling by leveraging the advantages of optical hardware integrated into silicon photonics.
Researchers found that people tend to trust machines more than humans when it comes to private information, which can lead to online behaviors. The presence of a machine agent on the interface triggers this 'machine heuristic,' making users more likely to share sensitive info.
Researchers found that tech-savvy people are more accepting of digital healthcare services, particularly when they have a strong belief in machine abilities and high levels of expertise. This suggests that designing interfaces to appeal to expert users can increase the adoption of automated healthcare providers.
A study found that Wi-Fi location influences online privacy behavior, with people in public spaces like coffee shops being more cautious when using public Wi-Fi. Participants who had a stronger 'publicness heuristic' tendency disclosed less information and engaged in fewer unethical behaviors when connected to public networks.
A recent study found that consumers' knowledge about toxicological principles is limited, leading to misconceptions about man-made versus natural chemicals. Emotions such as disgust also play a significant role in accepting new food technologies, with a negative association between willingness to eat and disgust responses.
Researchers designed video games to enhance heuristic judgment in emergency medicine physicians. The intervention improved accuracy in trauma triage decisions, with participants who used the games showing a 17-18 point lower under-triage rate compared to those receiving no intervention.
The study investigates KAPS surveys' use in Nepal's development, highlighting potential 'epistemic pollution.' It suggests neoliberal values have led to research serving solely instrumental and ritualistic purposes.
A new video game has been shown to improve doctors' ability to recognize and triage severe trauma patients, outperforming traditional text-based education. The game, which uses narrative engagement to promote behavior change, recalibrated physicians' brains to make quicker decisions with incomplete information.
Researchers at Florida State University discovered that adopting a 'code of the street' culture can increase arrest and conviction rates. They found that individuals who adhere to this code are disproportionately more likely to be arrested and convicted, even after controlling for factors like poverty and unemployment.
The Gerontological Society of America has released a new publication to help healthcare professionals overcome common heuristics and cognitive biases that can lead to poor decision making. Awareness of these biases is key to making informed decisions, according to the report.
A study by geographers at Dartmouth College and the University of Sheffield maps out complex networks of economic systems, natural resources, and infrastructure in US megaregions. The analysis reveals functional regions within broader areas, emphasizing the role of economic geography in understanding community needs.
A new planning algorithm generates backup plans efficiently and provides mathematical guarantees on its risk of failure, while also identifying conditions that trigger a switch to a particular contingency plan. The algorithm uses probabilistic pruning and optimistic heuristics to make the problem tractable.
A new video game called VERITAS aims to improve deception detection skills by training players to identify heuristics and detect deception through questioning. The game, developed by UCSB researcher Norah Dunbar, is designed for law enforcement and intelligence communities.
A study published in Psychological Science found that people with extreme political beliefs are less influenced by outside information and more resistant to the anchor bias, suggesting they make more confident judgments. The results suggest that political extremists' strong belief in the superiority of their ideology may be a key factor.
Researchers found that mobile users tend to distrust sites with instant gratification messages, and are more willing to share sensitive information after viewing security alerts. This phenomenon suggests that users prioritize privacy over convenience in digital interactions.
A study found that messiness can lead consumers to prefer simpler products and think more clearly, particularly for conservative individuals. This effect is attributed to heuristic information processing, which simplifies product representations.
Researchers found that participants trusted specialized technology more than general websites and recommendation agents, with cumulative interaction increasing trust. The study suggests mental shortcuts, such as heuristics, contribute to the perception of expertise and trustworthiness in labeled e-commerce tools.
A new study in the Journal of Consumer Research found that people's level of desire to think analytically about choices (NFC) and cognitive load significantly impact their use of mental shortcuts when making product selections. Researchers identified two factors that can lead consumers to use heuristics, including NFC and cognitive load.
To keep up with the potential half-billion users, MySpace is working with a University of Southern California specialist to improve server performance. Researchers are exploring a new heuristic algorithm to maintain and replace data in DRAM, aiming to increase capacity and speed.
A study by Ritesh Saini and Ashwani Monga found that consumers use heuristics to make decisions when spending time, rather than money. This approach leads to differences in decision-making, with a greater reliance on intuitive judgments.
A team of psychologists found that people's emotional desire for a mate leads them to believe there are fewer desirable partners available, even when the numbers are equal. This 'value heuristic' affects judgmental decisions in everyday life and can sometimes lead to unrealistic assumptions about reality
A study reveals consumers misjudge situations where longer duration isn't necessarily better, such as in exercise programs or lock-picking services. Consumers tend to believe a positive correlation between duration and quality, leading them to prefer longer sessions even when they're not more effective.
Assistant Professor Michael Fry and student Andrew Lundberg developed a model to help fantasy football players make informed decisions during drafts. The team's approach uses a combination of player value, available players, and team need to identify the best players to select.
