Harmful effects of digital tech – the science ‘needs fixing’, experts argue

fpjl2 — Thu, 10 Apr 2025 18:01:05 +0000

Scientific research on the harms of digital technology is stuck in a ‘failing cycle’ that moves too slowly to allow governments and society to hold tech companies to account, according to two leading researchers in a new report published in the journal Science.

Dr Amy Orben from the ��Ī and Dr J Nathan Matias from Cornell University say the pace at which new technology is deployed to billions of people has put unbearable strain on the scientific systems trying to evaluate its effects.

They argue that big tech companies effectively outsource research on the safety of their products to independent scientists at universities and charities who work with a fraction of the resources – while firms also obstruct access to essential data and information. This is in contrast to other industries where safety testing is largely done ‘in house’.

Orben and Matias call for an overhaul of ‘evidence production’ assessing the impact of technology on everything from mental health to discrimination.

Their recommendations include accelerating the research process, so that policy interventions and safer designs are tested in parallel with initial evidence gathering, and creating registries of tech-related harms informed by the public.

“Big technology companies increasingly act with perceived impunity, while trust in their regard for public safety is fading,” said Orben, of ��Ī’s MRC Cognition and Brain Sciences Unit. “Policymakers and the public are turning to independent scientists as arbiters of technology safety.”

“Scientists like ourselves are committed to the public good, but we are asked to hold to account a billion-dollar industry without appropriate support for our research or the basic tools to produce good quality evidence quickly.”

“We must urgently fix this science and policy ecosystem so we can better understand and manage the potential risks posed by our evolving digital society,” said Orben.

'Negative feedback cycle'

In the latest Science paper, the researchers point out that technology companies often follow policies of rapidly deploying products first and then looking to ‘debug’ potential harms afterwards. This includes distributing generative AI products to millions before completing basic safety tests, for example.

When tasked with understanding potential harms of new technologies, researchers rely on ‘routine science’ which – having driven societal progress for decades – now lags the rate of technological change to the extent that it is becoming at times ‘unusable’.

With many citizens pressuring politicians to act on digital safety, Orben and Matias argue that technology companies use the slow pace of science and lack of hard evidence to resist policy interventions and “minimize their own responsibility”.

Even if research gets appropriately resourced, they note that researchers will be faced with understanding products that evolve at an unprecedented rate.

“Technology products change on a daily or weekly basis, and adapt to individuals. Even company staff may not fully understand the product at any one time, and scientific research can be out of date by the time it is completed, let alone published,” said Matias, who leads Cornell’s Citizens and Technology (CAT) Lab.

“At the same time, claims about the inadequacy of science can become a source of delay in technology safety when science plays the role of gatekeeper to policy interventions,” Matias said.

“Just as oil and chemical industries have leveraged the slow pace of science to deflect the evidence that informs responsibility, executives in technology companies have followed a similar pattern. Some have even allegedly refused to commit substantial resources to safety research without certain kinds of causal evidence, which they also decline to fund.”

The researchers lay out the current ‘negative feedback cycle’:

Tech companies do not adequately resource safety research, shifting the burden to independent scientists who lack data and funding. This means high-quality causal evidence is not produced in required timeframes, which weakens government’s ability to regulate – further disincentivising safety research, as companies are let off the hook.

Orben and Matias argue that this cycle must be redesigned, and offer ways to do it.

Reporting digital harms

To speed up the identification of harms caused by online technologies, policymakers or civil society could construct registries for incident reporting, and encourage the public to contribute evidence when they experience harms.

Similar methods are already used in fields such as environmental toxicology where the public reports on polluted waterways, or vehicle crash reporting programs that inform automotive safety, for example.

“We gain nothing when people are told to mistrust their lived experience due to an absence of evidence when that evidence is not being compiled,” said Matias.

Existing registries, from mortality records to domestic violence databases, could also be augmented to include information on the involvement of digital technologies such as AI.

The paper’s authors also outline a ‘minimum viable evidence’ system, in which policymakers and researchers adjust the ‘evidence threshold’ required to show potential technological harms before starting to test interventions.

These evidence thresholds could be set by panels made up of affected communities, the public, or ‘science courts’: expert groups assembled to make rapid assessments.

“Causal evidence of technological harms is often required before designers and scientists are allowed to test interventions to build a safer digital society,” said Orben.

“Yet intervention testing can be used to scope ways to help individuals and society, and pinpoint potential harms in the process. We need to move from a sequential system to an agile, parallelised one.”

Under a minimum viable evidence system, if a company obstructs or fails to support independent research, and is not transparent about their own internal safety testing, the amount of evidence needed to start testing potential interventions would be decreased.

Orben and Matias also suggest learning from the success of ‘Green Chemistry’, which sees an independent body hold lists of chemical products ranked by potential for harm, to help incentivise markets to develop safer alternatives.

“The scientific methods and resources we have for evidence creation at the moment simply cannot deal with the pace of digital technology development,” Orben said.

“Scientists and policymakers must acknowledge the failures of this system and help craft a better one before the age of AI further exposes society to the risks of unchecked technological change.”

Added Matias: “When science about the impacts of new technologies is too slow, everyone loses.”

From social media to AI, online technologies are changing too fast for the scientific infrastructure used to gauge their public health harms, say two leaders in the field.

��Ī leads governmental project to understand impact of smartphones and social media on young people

cjb250 — Thu, 16 Jan 2025 00:01:37 +0000

The work has been commissioned by the UK government’s Department for Science, Innovation and Technology after a review by the UK Chief Medical Officer in 2019 found the evidence base around the links to children’s mental health were insufficient to provide strong conclusions suitable to inform policy.

The project – led by a team at the ��Ī, in collaboration with researchers at several leading UK universities – is aimed at improving policymakers’ understanding of the relationship between children’s wellbeing and smartphone use, including social media and messaging. It will help direct future government action in this area.

Project lead Dr Amy Orben from the Medical Research Council Cognition and Brain Sciences Unit (MRC CBU) at the ��Ī said: “There is huge concern about the impact of smartphone use on children's health, but the evidence base remains fairly limited. While the government is under substantial time pressure to make decisions, these will undoubtedly be better if based on improved evidence.

“This is a complex and rapidly evolving issue, with both potential harms and benefits associated with smartphone use. Technology is changing by the day, and scientific evidence creation needs to evolve and innovate to keep up.

“Our focus will be on deepening our causal understanding of the effects of new technologies, particularly over short timescales, to ensure that decisions are informed, timely and evidence-based.”

Dr Orben will lead a Project Delivery Team, with Consortium Members from the universities of Bath, Birmingham, Bristol, Glasgow, Manchester, Nottingham, Oxford and York and the London School of Economics. It will aim to identify which research methods and data sources will be most effective at identifying potential causal relationships between social media, smartphones, and the health and development of children and young people

Deputy project lead Dr Amrit Kaur Purba, also from the MRC CBU at ��Ī, said: “The impact of social media on young people is a pressing issue, and our project will ensure the research community is in a strong position to provide policymakers with the causal and high-quality insights they need. While we don’t expect this to be straightforward, our research will leverage diverse expertise from across the UK to deliver a comprehensive and informed response to make recommendations for how research in this area should be supported in future.”

The researchers will review and summarise existing research on the impact of smartphones and social media on children and young people’s mental health, wellbeing, physical health, lifestyle and health behaviours, and educational attainment. The review will recognise the diversity of perspectives that exist in this area and consider where further research could add valuable new insights to the evidence base.

They will assess the various methods and data available to understand the causal impacts, including recognising that online habits and emerging technologies are changing at a rapid pace, and considering how the experiences of vulnerable children and young people – for example, LGBTQ+ young people and those with special needs or mental health issues – can be captured in future research projects.

This will allow the team to recommend and outline how future research studies could deliver robust and causal evidence on the impact of smartphones and social media on child development factors in the next two to three years.

Technology Secretary Peter Kyle, said: "The online world offers immense opportunities for young people to connect and learn. Ensuring they can do so in an environment which puts their safety first is my priority and will guide this government’s action on online safety.

“That’s why we have launched new research, led by the ��Ī with support from other top UK universities, to better understand the complex relationship between technology and young people's wellbeing.

“This vital research will build a trusted evidence base for future action, helping us to protect and empower the next generation towards a safer and more positive digital future."

��Ī researchers are leading the first phase of a new research project that will lay the groundwork for future studies into the impact on children of smartphone and social media use.

This is a complex and rapidly evolving issue, with both potential harms and benefits associated with smartphone use. Technology is changing by the day, and scientific evidence creation needs to evolve and innovate to keep up

��Ī researchers recognised as Future Leaders by UKRI

lw355 — Mon, 04 Dec 2023 09:23:43 +0000

Future Leaders Fellowships are awarded by UK Research and Innovation (UKRI) to support universities and businesses in developing their most talented early career researchers and innovators, and to attract new people to their organisations, including from overseas.

The 75 'most promising research leaders' recognised today by UKRI will benefit from £101 million to tackle major global issues and to commercialise their innovations in the UK.

UKRI Chief Executive, Professor Dame Ottoline Leyser, said: “UKRI’s Future Leaders Fellowships provide researchers and innovators with long-term support and training, giving them the freedom to explore adventurous new ideas, and to build dynamic careers that break down the boundaries between sectors and disciplines.

“The fellows announced today illustrate how this scheme empowers talented researchers and innovators to build the diverse and connected research and innovation system we need to shorten the distance between discovery and prosperity across the UK.”

The four ��Ī researchers are:

Dr Alecia-Jane Twigger (Department of Pharmacology) (pictured)

Breastfeeding has been highlighted by the World Health Organization (WHO) as “one of the most effective ways to ensure child health and survival”. A major priority of the WHO is to increase the global rate of exclusive breastfeeding for the first 6 months up to at least 50% by 2025. However, many mothers worry about low milk production – a major driver for mothers switching to formula feeding. With funding provided by the Future Leaders Fellowship, Dr Twigger will establish state-of-the-art models of lactation with the aim of developing and trialling treatments to support low-milk production mothers in partnership with breastfeeding advocates and clinical stakeholders.

Dr Amy Orben (MRC Cognition and Brain Sciences Unit and Fellow of St John's College)

Dr Amy Orben will pinpoint how social media use might be linked to mental health risk in teenagers, a time when we are especially susceptible to developing mental health conditions. She will use a range of innovative techniques to study technological designs, such as the quantification of social feedback through ‘like’ counts, that could be problematic and therefore a target for future regulation. As a UKRI Future Leader Fellow, Dr Orben will also collaborate flexibly with youth, policymakers and charities to swiftly address pressing questions about social media and technology, helping to safeguard young people.

Dr Anna Moore (Department of Psychiatry)

Seventy percent of children suffering mental health problems are unable to access services and those who can are waiting longer than ever for help. Working with children, families and ��Ī Children’s Hospital project, Dr Anna Moore is developing easy-to-use digital tools to revolutionise mental health treatment for the young, by helping clinicians diagnose conditions much earlier. The system, called Timely, will use AI to analyse patient data, joining the dots to spot the early signs of mental health conditions. The tool will be designed to reduce health inequality, improve service efficiency and ensure data use is ethical and publicly acceptable.

Dr Niamh Gallagher (Faculty of History and Fellow of St Catharine’s College)

Dr Gallagher will lead ground-breaking historical research into one of the greatest geopolitical transformations of the 20th century, the disappearance of the British Empire, by investigating how Ireland, the Irish and a series of so-called ‘Irish Questions’ influenced the multifarious 'ends' of the Empire, from 1886 to today. With partners spanning education, public policy and the media, this research will produce a series of innovative outputs and shareable recommendations that facilitate pathways to cohesion in post-conflict Northern Ireland and enhance British–Irish relations in the aftermath of Brexit.

Four researchers are among the UK’s “most promising research leaders” who will benefit from £101 million from UKRI to tackle major global issues and commercialise their innovations.

The fellows announced today illustrate how this scheme empowers talented researchers and innovators to build the diverse and connected research and innovation system we need to shorten the distance between discovery and prosperity across the UK.

Lack of computer access linked to poorer mental health in young people during COVID-19 pandemic

cjb250 — Mon, 14 Nov 2022 08:00:07 +0000

The team found that the end of 2020 was the time when young people faced the most difficulties and that the mental health of those young people without access to a computer tended to deteriorate to a greater extent than that of their peers who did have access.

The COVID-19 pandemic had a significant effect on young people’s mental health, with evidence of rising levels of anxiety, depression, and psychological distress. Adolescence is a period when people are particularly vulnerable to developing mental health disorders, which can have long-lasting consequences into adulthood. In the UK, the mental health of children and adolescents was already deteriorating before the pandemic, but the proportion of people in this age group likely to be experiencing a mental health disorder increased from 11% in 2017 to 16% in July 2020.

The pandemic led to the closure of schools and an increase in online schooling, the impacts of which were not felt equally. Those adolescents without access to a computer faced the greatest disruption: in one study 30% of school students from middle-class homes reported taking part in live or recorded school lessons daily, while only 16% of students from working-class homes reported doing so.

In addition to school closures, lockdown often meant that young people could not meet their friends in person. During these periods, online and digital forms of interaction with peers, such as through video games and social media, are likely to have helped reduce the impact of these social disruptions.

Tom Metherell, who at the time of the study was an undergraduate student at Fitzwilliam College, ��Ī, said: “Access to computers meant that many young people were still able to ‘attend’ school virtually, carry on with their education to an extent and keep up with friends. But anyone who didn’t have access to a computer would have been at a significant disadvantage, which would only risk increasing their sense of isolation.”

To examine in detail the impact of digital exclusion on the mental health of young people, Metherell and colleagues examined data from 1,387 10–15-year-olds collected as part of Understanding Society, a large UK-wide longitudinal survey. They focused on access to computers rather than smartphones, as schoolwork is largely possible only on a computer while at this age most social interactions occur in person at school.

The results of their study are published in Scientific Reports.

Participants completed a questionnaire that assesses common childhood psychological difficulties, which allowed the Understanding Society team to score them on five areas: hyperactivity/inattention, prosocial behaviour, emotional, conduct and peer relationship problems. From this, they derived a ‘Total Difficulties’ score for each individual.

Over the course of the pandemic, the researchers noted small changes in overall mental health of the group, with average Total Difficulties scores increasing form pre-pandemic levels of 10.7 (out of a maximum 40), peaking at 11.4 at the end of 2020 before declining to 11.1 by March 2021.

Those young people who had no access to a computer saw the largest increase in their Total Difficulties scores. While both groups of young people had similar scores at the start of the pandemic, when modelled with adjustment for sociodemographic factors, those without computer access saw their average scores increase to 17.8, compared to their peers, whose scores increased to 11.2. Almost one in four (24%) young people in the group without computer access had Total Difficulties scores classed as ‘high’ or ‘very high’ compared to one in seven (14%) in the group with computer access.

Metherell, now a PhD student at UCL, added: “Young people’s mental health tended to suffer most during the strictest periods of lockdown, when they were less likely to be able go to school or see friends. But those without access to a computer were the worst hit – their mental health suffered much more than their peers and the change was more dramatic.”

Dr Amy Orben from the Medical Research Council (MRC) Cognition and Brain Sciences at the ��Ī, the study’s senior author, added: “Rather than always focusing on the downsides of digital technology on young people’s mental health, we need to recognise that it can have important benefits and may act as a buffer for their mental health during times of acute social isolation, such as the lockdown.

“We don’t know if and when a future lockdown will occur, but our research shows that we need to start thinking urgently how we can tackle digital inequalities and help protect the mental health of our young people in times when their regular in-person social networks are disrupted.”

The researchers argue that policymakers and public health officials need to recognise the risks of ‘digital exclusion’ to young people’s mental health and prioritise ensuring equitable digital access.

Dr Amy Orben is a Research Fellow at Emmanuel College, ��Ī.

Scientists find that the impact of social media on wellbeing varies across adolescence

cjb250 — Mon, 28 Mar 2022 10:00:41 +0000

In a study published today in Nature Communications, the researchers show that, in UK data, girls experience a negative link between social media use and life satisfaction when they are 11-13 years old and boys when they are 14-15 years old. Increased social media use again predicts lower life satisfaction at age 19 years. At other times the link was not statistically significant.

In just over a decade, social media has fundamentally changed how we spend our time, share information about ourselves, and talk to others. This has led to widespread concern about its potential negative impact, both on individuals and on the wider society. Yet, even after years of research, there is still considerable uncertainty about how social media use relates to wellbeing.

A team of scientists including psychologists, neuroscientists and modellers analysed two UK datasets comprising some 84,000 individuals between the ages of 10 and 80 years old. These included longitudinal data – that is, data that tracks individuals over a period of time – on 17,400 young people aged 10-21 years old. The researchers are from the ��Ī, University of Oxford, and the Donders Institute for Brain, Cognition and Behaviour.

The team looked for a connection between estimated social media use and reported life satisfaction and found key periods of adolescence where social media use was associated with a decrease in life satisfaction 12 months later. In the opposite direction, the researchers also found that teens who have lower than average life satisfaction use more social media one year later.

In girls, social media use between the ages of 11 and 13 years was associated with a decrease in life satisfaction one year later, whereas in boys this occurred between the ages of 14 and 15 years. The differences suggest that sensitivity to social media use might be linked to developmental changes, possibly changes in the structure of the brain, or to puberty, which occurs later in boys than in girls. This requires further research.

In both females and males, social media use at the age of 19 years was again associated with a decrease in life satisfaction a year later. At this age, say the researchers, it is possible that social changes – such as leaving home or starting work – may make us particularly vulnerable. Again, this requires further research.

At other times, the link between social media use and life satisfaction one year later was not statistically significant. Decreases in life satisfaction also predicted increases in social media use one year later; however this does not change across age and or differ between the sexes.

Dr Amy Orben a group leader at the MRC Cognition and Brain Sciences Unit, ��Ī, who led the study, said: “The link between social media use and mental wellbeing is clearly very complex. Changes within our bodies, such as brain development and puberty, and in our social circumstances appear to make us vulnerable at particular times of our lives.”

Professor Sarah-Jayne Blakemore, Professor of Psychology and Cognitive Neuroscience at ��Ī and a co-author of the study, said: “It’s not possible to pinpoint the precise processes that underlie this vulnerability. Adolescence is a time of cognitive, biological and social change, all of which are intertwined, making it difficult to disentangle one factor from another. For example, it is not yet clear what might be due to developmental changes in hormones or the brain and what might be down to how an individual interacts with their peers.”

Dr Orben added: “With our findings, rather than debating whether or not the link exists, we can now focus on the periods of our adolescence where we now know we might be most at risk and use this as a springboard to explore some of the really interesting questions.”

Further complicating the relationship is the fact – previously reported and confirmed by today’s findings – that not only can social media use negatively impact wellbeing, but that the reverse is also true and lower life satisfaction can drive increased social media use.

The researchers are keen to point out that, while their findings show at a population level that there is a link between social media use and poorer wellbeing, it is not yet possible to predict which individuals are most at risk.

Professor Rogier Kievit, Professor of Developmental Neuroscience at the Donders Institute for Brain, Cognition, and Behaviour, said: “Our statistical modelling examines averages. This means not every young person is going to experience a negative impact on their wellbeing from social media use. For some, it will often have a positive impact. Some might use social media to connect with friends, or cope with a certain problem or because they don't have anyone to talk to about a particular problem or how they feel – for these individuals, social media can provide valuable support.”

Professor Andrew Przybylski, Director of Research at the Oxford Internet Institute at the University of Oxford said: “To pinpoint which individuals might be influenced by social media, more research is needed that combines objective behavioural data with biological and cognitive measurements of development. We therefore call on social media companies and other online platforms to do more to share their data with independent scientists, and, if they are unwilling, for governments to show they are serious about tackling online harms by introducing legislation to compel these companies to be more open.”

The research was supported by Emmanuel College, the UK Economic and Social Research Council, the Huo Family Foundation, Wellcome, the Jacobs Foundation, the Wellspring Foundation, the RadboudUMC and the Medical Research Council.
