(Press-News.org) While people are growing more accustomed to AI-driven personal assistants, customer service chatbots and even financial advisors, when it comes to healthcare, most still want it with a human touch.
Given that receiving healthcare is a deeply personal experience, it’s understandable that patients prefer it to come from, well, a person. But with AI’s vast potential to increase the quality, efficacy and efficiency of medicine, a push toward greater acceptance of artificial intelligence-driven medicine could unlock benefits for patients and providers.
How, then, can the industry help nudge the public to feel more comfortable with medical AI?
According to a new study from researchers at Lehigh University and Seattle University, making the concept of bias more salient in their thinking can help.
Study explores ‘bias salience’
The study, published in the journal Computers in Human Behavior, found that patients were more receptive to medical recommendations from AI when they were made more aware of the biases inherent in human healthcare decisions. This “bias salience,” or making people more conscious of bias in decision-making, was shown to shift people’s perceptions.
“This increased receptiveness to AI occurs because bias is perceived to be a fundamentally human shortcoming,” said Rebecca J. H. Wang, associate professor of marketing in the Lehigh College of Business. ”As such, when the prospect of bias is made salient, perceptions of AI integrity—defined as the perceived fairness and trustworthiness of an AI agent relative to a human counterpart—are enhanced.”
The study entailed six experiments with nearly 1,900 participants, demonstrating that when participants were reminded of human biases—such as how healthcare providers might treat patients differently based on characteristics like gender—they became more receptive to AI recommendations.
Participants were presented with scenarios in which they would be seeking a recommendation or diagnosis such as a coronary bypass or skin cancer screening. They were then asked whether they preferred the recommendation to be made by a human being or by a computer/AI assistant.
Prior to being presented with the scenario, some participants were presented with prior screens intended to increase bias salience. These interventions included reviewing an infographic that highlighted common cognitive biases, describing a time when they were negatively affected by bias, including age-related bias for those over 50, and gender-related bias. The results showed:
When participants were made aware of potential biases in human healthcare, they rated AI as offering greater "integrity," meaning they perceived it as more fair and trustworthy.
While bias salience did not eliminate people’s general preference for human healthcare, high bias salience reduces resistance to medical AI, presumably because bias is more readily associated with human beings.
In the absence of bias salience, the subjectivity of human providers is often viewed as a positive, but when bias salience is high, patients place greater value on the perceived objectivity of AI.
The future of AI in medicine
The authors stress the importance of keeping human biases in mind at all stages of AI proliferation, from development to adoption. Developers of AI systems should both aim to minimize bias inherent in the materials used to train medical AI—a known issue in the current development of AI systems—and provide context about human bias when users encounter it.
Doing so could help providers capitalize on AI’s growing role in applications such as diagnostics, treatment recommendations, and patient monitoring. Those roles are only expected to expand as the industry is projected to invest more than $30 billion into AI medicine annually by 2029.
“By addressing patients’ concerns about AI and highlighting the limitations of human judgment, healthcare providers can create a more balanced and trusting relationship between patients and emerging technologies,” Wang said.
The study was a collaboration between Wang; Lucy E. Napper, associate professor of psychology at Lehigh; Jessecae Marsh, professor of psychology and associate dean at Lehigh; and Mathew S. Isaac, professor and chair of the department of marketing at Seattle University. The paper, “To err is human: Bias salience can help overcome resistance to medical AI,” is available online.

Beware of the full moon: Tropical forest mammals shy away from the moonlight
2024-10-16
A recent study using automatic wildlife cameras across three continents has shed light on how the moon's phases affect the behaviour of tropical forest mammals. Half of the species studied altered their activity levels or timing, or both, in response to the full moon. The findings suggest that even in some of the darkest places on earth - the floors of tropical forests - the moon's phases can influence animal behaviour. This impact could be even more pronounced in degraded and fragmented forests.

Energy-thirsty indoor vertical gardens ripe for improvement
2024-10-16
Indoor vertical gardens are gaining popularity among homeowners and restaurants, allowing them to grow microgreens year-round, but new research has identified a major drawback: their demands on energy.
A study by researchers from the Marche Polytechnic University and University of South Australia shows that while domestic vertical garden appliances can provide fresh, local produce under controlled conditions and with zero food miles, they do chew up energy.
Artificial lighting – essential for plant growth – accounted for more than 50% of the total energy costs in growing a crop of red lettuce, which is five times higher than professional ...
Around 40% of postmenopausal hormone positive breast cancers linked to excess body fat
2024-10-15
Around 40% of postmenopausal hormone positive breast cancer cases may be linked to excess body fat, suggests Spanish research published online in the Journal of Epidemiology & Community Health.
This proportion is significantly higher than 1 in 10 such cases currently attributed to excess weight, using the widely used measure of body mass index (BMI), and indicates that the real impact of obesity on breast cancer risk has likely been underestimated, say the researchers.
BMI isn’t necessarily a very accurate measure of body fat, particularly in older women, because it doesn’t account for age, sex, or ethnicity, they point out.
They therefore ...
No evidence for belief that nut allergens spread through aircraft ventilation systems
2024-10-15
There is no evidence for the commonly held belief that nut allergens can be spread through aircraft ventilation systems, say allergy and aviation medicine specialists in an evidence review published in the Archives of Disease in Childhood.
Allergen residues on surfaces, such as tray tables, and seat-back video screens, pose the main risk—a risk that is likely heightened by the fast turnaround times deployed by many low-cost carriers, they suggest.
And allergic reactions to foods are around 10 to 100 times less common during flights than they are ‘on the ground,’ they point out, although this could be due to passengers with food allergies ...

High potency cannabis is defined as having Delta-9-tetrahydrocannabinol (THC) content of 10 per cent or more.
The research also showed the effect of cannabis use on DNA is different in people experiencing their first episode of psychosis compared to users who have never experienced psychosis, ...
Out-of-this-world simulation key to collecting moon dust
2024-10-15
Teleoperated robots for gathering moon dust are a step closer, according to new research by scientists at the University of Bristol.
The team were able to complete a sample collection task by controlling a virtual simulation, which then sent commands to a physical robot to mirror the simulation’s actions. They were able to do so while only monitoring the simulation - without needing physical camera streams - meaning this tool could be particularly useful for delayed teleoperation on the Moon.
Alongside a boom in lunar lander missions ...

Typically, wireless networks transmit information using radio waves over ...
Isolated older people more likely to have low levels of key nutrients in their diet
2024-10-15
Older adults in the UK who are socially isolated are more likely to have an insufficient intake of key micronutrients such as vitamin C and vitamin B6, increasing their risk of health problems, according to a new study led by UCL (University College London) researchers.
The study, published in the journal Age and Ageing, looked at data from 3,713 people in the UK aged 50 and over who filled in a detailed questionnaire about what they ate and drank on two separate days.
The researchers found that people who were more socially isolated were more likely to have a lower than recommended intake of five micronutrients ...
Brazilian researchers work to transform agave into the ‘sugarcane of the sertão’
2024-10-15
Climate change has caused an increase in the semi-arid climate region in Brazil. Data from the National Center for Monitoring and Warning of Natural Disasters (CEMADEN) and the National Institute of Space Research (INPE) in the South American country indicate an expansion of 7,500 square kilometers per year since 1990, which is equivalent to five times the area of the city of São Paulo. A similar phenomenon has been observed in some regions of Europe and North Africa.
With this in mind, and with the desire to find solutions to mitigate climate change, a group ...
