What can we learn from billions of food purchases derived from fidelity cards?

Curated on Posted on by Stefaan Verhulst

Daniele Quercia at Medium: “By combining 1.6B food item purchases with 1.1B medical prescriptions for the entire city of London for one year, we discovered that, to predict health outcomes, socio-economic conditions matter less than what previous research has shown: despite being of lower-income, certain areas are healthy, and that is because of what their residents eat!

This result comes from our latest project “Poor but Healthy”, which was published in the Springer European Physical Journal (EPJ) of Data Science this month, and comes with a @tobi_vierzwo’s stunningly beautiful map of London I invite all of you to explore.

Why are we interested in urban health? In our cities, food is cheap and exercise discretionary, and health takes its toll. Half of European citizens will be obese by 2050, and obesity and its diseases are likely to reach crisis proportions. In this project, we set out to show that fidelity cards of grocery stores represent a treasure trove of health data — they can be used not only to (e)mail discount coupons to customers but also to effectively track a neighbourhood’s health in real-time for an entire city or even an entire country.

In research circles, the impact of eating habits on people’s health has mostly been studied using dietary surveys, which are costly and of limited scale.

To complement these surveys, we have recently resorted to grocery fidelity cards. We analyzed the anonymized records of 1.6B grocery items purchased by 1.6M grocery store customers in London over one whole year, and combined them with 1.1B medical prescriptions.

In so doing, we found that, as one expects, the “trick” to not being associated with chronic diseases is eating less what we instinctively like (e.g., sugar, carbohydrates), balancing all the nutrients, and avoiding the (big) quantities that are readily available. These results come as no surprise yet speak to the validity of using fidelity cards to capture health outcomes…(More)”.


Living Labs As A Collaborative Framework For Changing Perceptions And Goals

Curated on Posted on by Stefaan Verhulst

Co-Val: “In the… ‘Report on cross-country comparison on existing innovation and living labs’, Lars Fuglsang and Anne Vorre Hansen from Roskilde University describe various applications of living labs to decision-making. The basic two examples are living labs as a collaborative framework for changing perceptions and goals and living labs as an ecosystem for policy innovation.

Living labs can involve a change in mindset and goals as expressed in one paper on public sector innovation labs (Carstensen & Bason, 2012). Carstensen and Bason (2012) report the important story of the Danish Mindlab (2002-2018) – a cross-governmental innovation lab involving public sector organisations, citizens and businesses in creating new solutions for society. They argue that innovation labs are designed to foster collaboration since labs are platforms where multiple stakeholders can engage in interaction, dialogue, and development activities.  Innovation needs a different approach than everyday activities and a change in mindset and culture shift of employees towards thinking more systematically about innovation. Mindlab’s methodologies are anchored in design thinking, qualitative research and policy development, with the aim of capturing the subjective reality experienced by both citizens and businesses in the development of new solutions. Carstensen and Bason (2012) list the following key principles of Mindlab: take charge of on-going renewal, maintain top management backing, create professional empathy, insist on collaboration, do – don’t just think, recruit and develop likeable people, don’t be too big, communicate.

Also, Buhr et al. (2016) show how living labs can be important for developing and implementing collective goals and creating new opportunities for citizens to influence public affairs. They describe two cases in two suburban areas (located in Sweden and Finland), where the living lab approach was used to improve the feeling of belonging in a community. In one of the two suburbs studied, a living lab approach was used to change the lightning on a pathway that seemed unsafe; and in the other case, a living lab approach was used to strengthen the social community by renovating a kiosk and organizing varied activities for the citizens. Both living labs motivated the residents to work on societal goals for sustainability and choose solutions. The study indicates that a living lab approach can be used for gaining support for change and thereby increasing the citizens’ appreciation of a local area. Further, living labs may give citizens a feeling that they are being listened to. Living labs can thus create opportunities for citizens to develop the city together with municipal policy-makers and other stakeholders and enable policy-makers to respond to the expressed needs of the citizens….(More)”

Nagging misconceptions about nudge theory

Curated on Posted on by Stefaan Verhulst

Cass Sunstein at The Hill: “Nudges are private or public initiatives that steer people in particular directions but that also allow them to go their own way.

A reminder is a nudge; so is a warning. A GPS device nudges; a default rule, automatically enrolling people in some program, is a nudge.

To qualify as a nudge, an initiative must not impose significant economic incentives. A subsidy is not a nudge; a tax is not a nudge; a fine or a jail sentence is not a nudge. To count as such, a nudge must fully preserve freedom of choice.

In 2009, University of Chicago economist Richard Thaler and I co-wrote a book that drew on research in psychology and behavioral economics to help people and institutions, both public and private, improve their decision-making.

In the 10 years since “Nudge” was published, there has been an extraordinary outpouring of new thought and action, with particular reference to public policy.

Behavioral insight teams, or “nudge units” of various sorts, can be found in many nations, including Australia, Canada, Denmark, United Kingdom, the United States, the Netherlands, Germany, Singapore, Japan and Qatar.

Those teams are delivering. By making government more efficient, and by improving safety and health, they are helping to save a lot of money and a lot of lives. And in many countries, including the U.S., they don’t raise partisan hackles; both Democrats and Republicans have enthusiastically embraced them.   

Still, there are a lot of mistakes and misconceptions out there, and they are diverting attention and hence stalling progress. Here are the three big ones:

1. Nudges do not respect freedom. …

2. Nudges are based on excessive trust in government...

3. Nudges cannot achieve a whole lot.…(More)”.

How Technology Could Revolutionize Refugee Resettlement

Curated on Posted on by Stefaan Verhulst

Krishnadev Calamur in The Atlantic: “… For nearly 70 years, the process of interviewing, allocating, and accepting refugees has gone largely unchanged. In 1951, 145 countries came together in Geneva, Switzerland, to sign the Refugee Convention, the pact that defines who is a refugee, what refugees’ rights are, and what legal obligations states have to protect them.

This process was born of the idealism of the postwar years—an attempt to make certain that those fleeing war or persecution could find safety so that horrific moments in history, such as the Holocaust, didn’t recur. The pact may have been far from perfect, but in successive years, it was a lifeline to Afghans, Bosnians, Kurds, and others displaced by conflict.

The world is a much different place now, though. The rise of populism has brought with it a concomitant hostility toward immigrants in general and refugees in particular. Last October, a gunman who had previously posted anti-Semitic messages online against HIAS killed 11 worshippers in a Pittsburgh synagogue. Many of the policy arguments over resettlement have shifted focus from humanitarian relief to security threats and cost. The Trump administration has drastically cut the number of refugees the United States accepts, and large parts of Europe are following suit.

If it works, Annie could change that dynamic. Developed at Worcester Polytechnic Institute in Massachusetts, Lund University in Sweden, and the University of Oxford in Britain, the software uses what’s known as a matching algorithm to allocate refugees with no ties to the United States to their new homes. (Refugees with ties to the United States are resettled in places where they have family or community support; software isn’t involved in the process.)

Annie’s algorithm is based on a machine learning model in which a computer is fed huge piles of data from past placements, so that the program can refine its future recommendations. The system examines a series of variables—physical ailments, age, levels of education and languages spoken, for example—related to each refugee case. In other words, the software uses previous outcomes and current constraints to recommend where a refugee is most likely to succeed. Every city where HIAS has an office or an affiliate is given a score for each refugee. The higher the score, the better the match.

This is a drastic departure from how refugees are typically resettled. Each week, HIAS and the eight other agencies that allocate refugees in the United States make their decisions based largely on local capacity, with limited emphasis on individual characteristics or needs….(More)”.

There Are Better Ways to Do Democracy

Curated on Posted on by Stefaan Verhulst

Article by Peter Coy: “The Brexit disaster has stained the reputation of direct democracy. The United Kingdom’s trauma began in 2016, when then-Prime Minister David Cameron miscalculated that he could strengthen Britain’s attachment to the European Union by calling a referendum on it. The Leave campaign made unkeepable promises about Brexit’s benefits. Voters spent little time studying the facts because there was a vanishingly small chance that any given vote would make the difference by breaking a tie. Leave won—and Google searches for “What is the EU” spiked after the polls closed.

Brexit is only one manifestation of a global problem. Citizens want elected officials to be as responsive as Uber drivers, but they don’t always take their own responsibilities seriously. This problem isn’t new. America’s Founding Fathers worried that democracy would devolve into mob rule; the word “democracy” appears nowhere in the Declaration of Independence or the Constitution.

While fears about democratic dysfunction are understandable, there are ways to make voters into real participants in the democratic process without giving in to mobocracy. Instead of referendums, which often become lightning rods for extremism, political scientists say it’s better to make voters think like jurors, whose decisions affect the lives and fortunes of others.

Guided deliberation, also known as deliberative democracy, is one way to achieve that. Ireland used it in 2016 and 2017 to help decide whether to repeal a constitutional amendment that banned abortion in most cases. A 99-person Citizens’ Assembly was selected to mirror the Irish population. It met over five weekends to evaluate input from lawyers and obstetricians, pro-life and pro-choice groups, and more than 13,000 written submissions from the public, guided by a chairperson from the Irish supreme court. Together they concluded that the legislature should have the power to allow abortion under a broader set of conditions, a recommendation that voters approved in a 2018 referendum; abortion in Ireland became legal in January 2019.

Done right, deliberative democracy brings out the best in citizens. “My experience shows that some of the most polarising issues can be tackled in this manner,” Louise Caldwell, an Irish assembly member, wrote in a column for the Guardian in January. India’s village assemblies, which involve all the adults in local decision-making, are a form of deliberative democracy on a grand scale. A March article in the journal Science says that “evidence from places such as Colombia, Belgium, Northern Ireland, and Bosnia shows that properly structured deliberation can promote recognition, understanding, and learning.” Even French President Emmanuel Macron has used it, convening a three-month “great debate” to solicit the public’s views on some of the issues raised by the sometimes-violent Yellow Vest movement. On April 8, Prime Minister Edouard Philippe presented one key finding: The French have “zero tolerance” for new taxes…(More)”.

Statistics Estonia to coordinate data governance

Curated on Posted on by Stefaan Verhulst

Article by Miriam van der Sangen at CBS: “In 2018, Statistics Estonia launched a new strategy for the period 2018-2022. This strategy addresses the organisation’s aim to produce statistics more quickly while minimising the response burden on both businesses and citizens. Another element in the strategy is addressing the high expectations in Estonian society regarding the use of data. ‘We aim to transform Statistics Estonia into a national data agency,’ says Director General Mägi. ‘This means our role as a producer of official statistics will be enlarged by data governance responsibilities in the public sector. Taking on such responsibilities requires a clear vision of the whole public data ecosystem and also agreement to establish data stewards in most public sector institutions.’…

the Estonian Parliament passed new legislation that effectively expanded the number of official tasks for Statistics Estonia. Mägi elaborates: ‘Most importantly, we shall be responsible for coordinating data governance. The detailed requirements and conditions of data governance will be specified further in the coming period.’ Under the new Act, Statistics Estonia will also have more possibilities to share data with other parties….

Statistics Estonia is fully committed to producing statistics which are based on big data. Mägi explains: ‘At the moment, we are actively working on two big data projects. One project involves the use of smart electricity meters. In this project, we are looking into ways to visualise business and household electricity consumption information. The second project involves web scraping of prices and enterprise characteristics. This project is still in an initial phase, but we can already see that the use of web scraping can improve the efficiency of our production process.’ We are aiming to extend the web scraping project by also identifying e-commerce and innovation activities of enterprises.’

Yet another ambitious goal for Statistics Estonia lies in the field of data science. ‘Similarly to Statistics Netherlands, we established experimental statistics and data mining activities years ago. Last year, we developed a so-called think-tank service, providing insights from data into all aspects of our lives. Think of birth, education, employment, et cetera. Our key clients are the various ministries, municipalities and the private sector. The main aim in the coming years is to speed up service time thanks to visualisations and data lake solutions.’ …(More)”.

Open Justice: Public Entrepreneurs Learn to Use New Technology to Increase the Efficiency, Legitimacy, and Effectiveness of the Judiciary

Curated on Posted on by Stefaan Verhulst

The GovLab: “Open justice is a growing movement to leverage new technologies – including big data, digital platforms, blockchain and more – to improve legal systems by making the workings of courts easier to understand, scrutinize and improve. Through the use of new technology, open justice innovators are enabling greater efficiency, fairness, accountability and a reduction in corruption in the third branch of government. For example, the open data portal ‘Atviras Teismas’ Lithuania (translated ‘open court’ Lithuania) is a platform for monitoring courts and judges through performance metrics’. This portal serves to make the courts of Lithuania transparent and benefits both courts and citizens by presenting comparative data on the Lithuanian Judiciary.

To promote more Open Justice projects, the GovLab in partnership with the Electoral Tribunal of the Federal Judiciary (TEPJF) of Mexico, launched an historic, first of its kind, online course on Open Justice. Designed primarily for lawyers, judges, and public officials – but also intended to appeal to technologists, and members of the public – the Spanish-language course consists of 10 modules.

Each of the ten modules comprises:

  1. A short video-based lecture
  2. An original Open Justice reader
  3. Associated additional readings
  4. A self-assessment quiz
  5. A demonstration of a platform or tool
  6. An interview with a global practitioner

Among those featured in the interviews are Felipe Moreno of Jusbrasil, Justin Erlich of OpenJustice California, Liam Hayes of Aurecon, UK, Steve Ghiassi of Legaler, Australia, and Sara Castillo of Poder Judicial, Chile….(More)”.

Rethink government with AI

Curated on Posted on by Stefaan Verhulst

Helen Margetts and Cosmina Dorobantu at Nature: “People produce more than 2.5 quintillion bytes of data each day. Businesses are harnessing these riches using artificial intelligence (AI) to add trillions of dollars in value to goods and services each year. Amazon dispatches items it anticipates customers will buy to regional hubs before they are purchased. Thanks to the vast extractive might of Google and Facebook, every bakery and bicycle shop is the beneficiary of personalized targeted advertising.

But governments have been slow to apply AI to hone their policies and services. The reams of data that governments collect about citizens could, in theory, be used to tailor education to the needs of each child or to fit health care to the genetics and lifestyle of each patient. They could help to predict and prevent traffic deaths, street crime or the necessity of taking children into care. Huge costs of floods, disease outbreaks and financial crises could be alleviated using state-of-the-art modelling. All of these services could become cheaper and more effective.

This dream seems rather distant. Governments have long struggled with much simpler technologies. Flagship policies that rely on information technology (IT) regularly flounder. The Affordable Care Act of former US president Barack Obama nearly crumbled in 2013 when HealthCare.gov, the website enabling Americans to enrol in health insurance plans, kept crashing. Universal Credit, the biggest reform to the UK welfare state since the 1940s, is widely regarded as a disaster because of its failure to pay claimants properly. It has also wasted £837 million (US$1.1 billion) on developing one component of its digital system that was swiftly decommissioned. Canada’s Phoenix pay system, introduced in 2016 to overhaul the federal government’s payroll process, has remunerated 62% of employees incorrectly in each fiscal year since its launch. And My Health Record, Australia’s digital health-records system, saw more than 2.5 million people opt out by the end of January this year over privacy, security and efficacy concerns — roughly 1 in 10 of those who were eligible.

Such failures matter. Technological innovation is essential for the state to maintain its position of authority in a data-intensive world. The digital realm is where citizens live and work, shop and play, meet and fight. Prices for goods are increasingly set by software. Work is mediated through online platforms such as Uber and Deliveroo. Voters receive targeted information — and disinformation — through social media.

Thus the core tasks of governments, such as enforcing regulation, setting employment rights and ensuring fair elections require an understanding of data and algorithms. Here we highlight the main priorities, drawn from our experience of working with policymakers at The Alan Turing Institute in London….(More)”.

Nudging the dead: How behavioural psychology inspired Nova Scotia’s organ donation scheme

Curated on Posted on by Stefaan Verhulst

Joseph Brean at National Post: “Nova Scotia’s decision to presume people’s consent to donating their organs after death is not just a North American first. It is also the latest example of how deeply behavioural psychology has changed policy debates.

That is a rare achievement for science. Governments used to appeal to people’s sense of reason, religion, civic duty, or fear of consequences. Today, when they want to change how their citizens behave, they use psychological tricks to hack their minds.

Nudge politics, as it came to be known, has been an intellectual hit among wonks and technocrats ever since Daniel Kahneman won the Nobel Prize in 2002 for destroying the belief people make decisions based on good information and reasonable expectations. Not so, he showed. Not even close. Human decision-making is an organic process, all but immune to reason, but strangely susceptible to simple environmental cues, just waiting to be exploited by a clever policymaker….

Organ donation is a natural fit. Nova Scotia’s experiment aims to solve a policy problem by getting people to do what they always tend to do about government requests — nothing.

The cleverness is evident in the N.S. government’s own words, which play on the meaning of “opportunity”: “Every Nova Scotian will have the opportunity to be an organ and tissue donor unless they opt out.” The policy applies to kidneys, pancreas, heart, liver, lungs, small bowel, cornea, sclera, skin, bones, tendons and heart valves.

It is so clever it aims to make progress as people ignore it. The default position is a positive for the policy. It assumes poor pickup. You can opt out of organ donation if you want. Nova Scotia is simply taking the informed gamble that you probably won’t. That is the goal, and it will make for a revealing case study.

Organ donation is an important question, and chronically low donation rates can reasonably be called a crisis. But most people make their personal choice “thoughtlessly,” as Kahneman wrote in the 2011 book Thinking, Fast and Slow.

He referred to European statistics which showed vast differences in organ donation rights between neighbouring and culturally similar countries, such as Sweden and Denmark, or Germany and Austria. The key difference, he noted, was what he called “framing effects,” or how the question was asked….(More)”.

OECD survey reveals many people unhappy with public services and benefits

Curated on Posted on by Stefaan Verhulst

Report by OECD: “Many people in OECD countries believe public services and social benefits are inadequate and hard to reach. More than half say they do not receive their fair share of benefits given the taxes they pay, and two-thirds believe others get more than they deserve. Nearly three out of four people say they want their government to do more to protect their social and economic security.  

These are among the findings of a new OECD survey, “Risks that Matter”, which asked over 22,000 people aged 18 to 70 years old in 21 countries about their worries and concerns and how well they think their government helps them tackle social and economic risks.

This nationally representative survey finds that falling ill and not being able to make ends meet are often at the top of people’s lists of immediate concerns. Making ends meet is a particularly common worry for those on low incomes and in countries that were hit hard by the financial crisis. Older people are most often worried about their health, while younger people are frequently concerned with securing adequate housing. When asked about the longer-term, across all countries, getting by in old age is the most commonly cited worry.

The survey reveals a dissatisfaction with current social policy. Only a minority are satisfied with access to services like health care, housing, and long-term care. Many believe the government would not be able to provide a proper safety net if they lost their income due to job loss, illness or old age. More than half think they would not be able to easily access public benefits if they needed them.

“This is a wake-up call for policy makers,” said OECD Secretary-General Angel Gurría. “OECD countries have some of the most advanced and generous social protection systems in the world. They spend, on average, more than one-fifth of their GDP on social policies. Yet, too many people feel they cannot count fully on their government when they need help. A better understanding of the factors driving this perception and why people feel they are struggling is essential to making social protection more effective and efficient. We must restore trust and confidence in government, and promote equality of opportunity.”

In every country surveyed except Canada, Denmark, Norway and the Netherlands, most people say that their government does not incorporate the views of people like them when designing social policy. In a number of countries, including Greece, Israel, Lithuania, Portugal and Slovenia, this share rises to more than two-thirds of respondents. This sense of not being part of the policy debate increases at higher levels of education and income, while feelings of injustice are stronger among those from high-income households.

Public perceptions of fairness are worrying. More than half of respondents say they do not receive their fair share of benefits given the taxes they pay, a share that rises to three quarters or more in Chile, Greece, Israel and Mexico. At the same time, people are calling for more help from government. In almost all countries, more than half of respondents say they want the government to do more for their economic and social security. This is especially the case for older respondents and those on low incomes.

Across countries, people are worried about financial security in old age, and most are willing to pay more to support public pension systems… (More)”.
