The GovLab Index: Designing for Behavior Change

Curated on Posted on by Stefaan Verhulst

Please find below the latest installment in The GovLab Index series, inspired by the Harper’s Index. “The GovLab Index: Designing for Behavior Change” explores the recent application of psychology and behavioral economics towards solving social issues and shaping public policy and programs. Previous installments include The Networked Public, Measuring Impact with Evidence, Open Data, The Data Universe, Participation and Civic Engagement and Trust in Institutions.

Big Data for Law

Curated on Posted on by Stefaan Verhulst

legislation.gov.uk: “The National Archives has received ‘big data’ funding from the Arts and Humanities Research Council (AHRC) to deliver the ‘Big Data for Law‘ project. Just over £550,000 will enable the project to transform how we understand and use current legislation, delivering a new service – legislation.gov.uk Research – by March 2015. There are an estimated 50 million words in the statute book, with 100,000 words added or changed every month. Search engines and services like legislation.gov.uk have transformed access to legislation. Law is accessed by a much wider group of people, the majority of whom are typically not legally trained or qualified. All users of legislation are confronted by the volume of legislation, its piecemeal structure, frequent amendments, and the interaction of the statute book with common law and European law. Not surprisingly, many find the law difficult to understand and comply with. There has never been a more relevant time for research into the architecture and content of law, the language used in legislation and how, through interpretation by the courts, it is given effect. Research that will underpin the drive to deliver good, clear and effective law. Researchers typically lack the raw data, the tools, and the methods to undertake research across the whole statute book. Meanwhile, the combination of low cost cloud computing, open source software and new methods of data analysis – the enablers of the big data revolution – are transforming research in other fields. Big data research is perfectly possible with legislation if only the basic ingredients – the data, the tools and some tried and trusted methods – were as readily available as the computing power and the storage. The vision for this project is to address that gap by providing a new Legislation Data Research Infrastructure at research.legislation.gov.uk. Specifically tailored to researchers’ needs, it will consist of downloadable data, online tools for end-users; and open source tools for researchers to download, adapt and use….
There are three main areas for research:

  • Understanding researchers’ needs: to ensure the service is based on evidenced need, capabilities and limitations, putting big data technologies in the hands of non-technical researchers for the first time.
  • Deriving new open data from closed data: no one has all the data that researchers might find useful. For example, the potentially personally identifiable data about users and usage of legislation.gov.uk cannot be made available as open data but is perfect for processing using existing big data tools; eg to identify clusters in legislation or “recommendations” datasets of “people who read Act A or B also looked at Act Y or Z”. The project will look whether it is possible to create new open data sets from this type of closed data. An N-Grams dataset and appropriate user interface for legislation or related case law, for example, would contain sequences of words/phrases/statistics about their frequency of occurrence per document. N-Grams are useful for research in linguistics or history, and could be used to provide a predictive text feature in a drafting tool for legislation.
  • Pattern language for legislation: We need new ways of codifying and modelling the architecture of the statute book to make it easier to research its entirety using big data technologies. The project will seek to learn from other disciplines, applying the concept of a ‘pattern language’ to legislation. Pattern languages have revolutionised software engineering over the last twenty years and have the potential to do the same for our understanding of the statute book. A pattern language is simply a structured method of describing good design practices, providing a common vocabulary between users and specialists, structured around problems or issues, with a solution. Patterns are not created or invented – they are identified as ‘good design’ based on evidence about how useful and effective they are. Applied to legislation, this might lead to a common vocabulary between the users of legislation and legislative drafters, to identifying useful and effective drafting practices and solutions that deliver good law. This could enable a radically different approach to structuring teaching materials or guidance for legislators.”

Habermas and the Garants : Narrowing the gap between policy and practice in French organisation – citizen engagement

Curated on Posted on by Stefaan Verhulst
New paper by Judy Burnside-Lawry, Carolyne Lee and Sandrine Rui: “This article draws on a case study of organisation–citizen engagement during railway infrastructure planning in southwest France, to examine the nature of participatory democracy, both conceptually —as elucidated by Habermas and others— and empirically, as recently practised within the framework of a model established in one democratically governed country.
We analyse roles played by the state organisation responsible for building railway infrastructure; the National Commission for Public Debate; and the Garants, who oversee and facilitate the participatory process as laid down by the French law of Public Debate. We conclude by arguing that despite its normative aspects and its lack of provision for analysis of power relations, Habermas’s theory of communicative action can be used to evaluate the quality of organisation –citizen engagement, potentially providing a basis for informing actual models of democratic participation.”

Selected Readings on Behavioral Economics: Nudges

Curated on Posted on by Andrew Young

The Living Library’s Selected Readings series seeks to build a knowledge base on innovative approaches for improving the effectiveness and legitimacy of governance. This curated and annotated collection of recommended works on the topic of behavioral economics was originally published in 2014.

The 2008 publication of Richard Thaler and Cass Sunstein’s Nudge ushered in a new era of behavioral economics, and since then, policy makers in the United States and elsewhere have been applying behavioral economics to the field of public policy. Like Smart Disclosure, behavioral economics can be used in the public sector to improve the decisionmaking ability of citizens without relying on regulatory interventions. In the six years since Nudge was published, the United Kingdom has created the Behavioural Insights Team (also known as the Nudge Unit), a cross-ministerial organization that uses behavioral economics to inform public policy, and the White House has recently followed suit by convening a team of behavioral economists to create a behavioral insights-driven team in the United States. Policymakers have been using behavioral insights to design more effective interventions in the fields of long term unemployment; roadway safety; enrollment in retirement plans; and increasing enrollment in organ donation registries, to name some noteworthy examples. The literature of this nascent field provides a look at the growing optimism in the potential of applying behavioral insights in the public sector to improve people’s lives.

Selected Reading List (in alphabetical order)

  • John Beshears, James Choi, David Laibson and Brigitte C. Madrian – The Importance of Default Options for Retirement Savings Outcomes: Evidence from the United States – a paper examining the role default options play in encouraging intelligent retirement savings decisionmaking.
  • Cabinet Office and Behavioural Insights Team, United Kingdom – Applying Behavioural Insights to Health – a paper outlining some examples of behavioral economics being applied to the healthcare landscape using cost-efficient interventions.
  • Matthew Darling, Saugato Datta and Sendhil Mullainathan – The Nature of the BEast: What Behavioral Economics Is Not – a paper discussing why control and behavioral economics are not as closely aligned as some think, reiterating the fact that the field is politically agnostic.
  • Antoinette Schoar and Saugato Datta – The Power of Heuristics – a paper exploring the concept of “heuristics,” or rules of thumb, which can provide helpful guidelines for pushing people toward making “reasonably good” decisions without a full understanding of the complexity of a situation.
  • Richard H. Thaler and Cass R. Sunstein – Nudge: Improving Decisions About Health, Wealth, and Happiness – an influential book describing the many ways in which the principles of behavioral economics can be and have been used to influence choices and behavior through the development of new “choice architectures.” 
  • U.K. Parliament Science and Technology Committee – Behaviour Change – an exploration of the government’s attempts to influence the behaviour of its citizens through nudges, with a focus on comparing the effectiveness of nudges to that of regulatory interventions.

Annotated Selected Reading List (in alphabetical order)

Beshears, John, James Choi, David Laibson and Brigitte C. Madrian. “The Importance of Default Options for Retirement Savings Outcomes: Evidence from the United States.” In Jeffrey R. Brown, Jeffrey B. Liebman and David A. Wise, editors, Social Security Policy in a Changing Environment, Cambridge: National Bureau of Economic Research, 2009. http://bit.ly/LFmC5s.

  • This paper examines the role default options play in pushing people toward making intelligent decisions regarding long-term savings and retirement planning.
  • Importantly, the authors provide evidence that a strategically oriented default setting from the outset is likely not enough to fully nudge people toward the best possible decisions in retirement savings. They find that the default settings in every major dimension of the savings process (from deciding whether to participate in a 401(k) to how to withdraw money at retirement) have real and distinct effects on behavior.

Cabinet Office and Behavioural Insights Team, United Kingdom. “Applying Behavioural Insights to Health.” December 2010. http://bit.ly/1eFP16J.

  • In this report, the United Kingdom’s Behavioural Insights Team does not attempt to “suggest that behaviour change techniques are the silver bullet that can solve every problem.” Rather, they explore a variety of examples where local authorities, charities, government and the private-sector are using behavioural interventions to encourage healthier behaviors.  
  • The report features case studies regarding behavioral insights ability to affect the following public health issues:
    • Smoking
    • Organ donation
    • Teenage pregnancy
    • Alcohol
    • Diet and weight
    • Diabetes
    • Food hygiene
    • Physical activity
    • Social care
  • The report concludes with a call for more experimentation and knowledge gathering to determine when, where and how behavioural interventions can be most effective in helping the public become healthier.

Darling, Matthew, Saugato Datta and Sendhil Mullainathan. “The Nature of the BEast: What Behavioral Economics Is Not.” The Center for Global Development. October 2013. https://bit.ly/2QytRmf.

  • In this paper, Darling, Datta and Mullainathan outline the three most pervasive myths that abound within the literature about behavioral economics:
    • First, they dispel the relationship between control and behavioral economics.  Although tools used within behavioral economics can convince people to make certain choices, the goal is to nudge people to make the choices they want to make. For example, studies find that when retirement savings plans change the default to opt-in rather than opt-out, more workers set up 401K plans. This is an example of a nudge that guides people to make a choice that they already intend to make.
    • Second, they reiterate that the field is politically agnostic. Both liberals and conservatives have adopted behavioral economics and its approach is neither liberal nor conservative. President Obama embraces behavioral economics but the United Kingdom’s conservative party does, too.
    • And thirdly, the article highlights that irrationality actually has little to do with behavioral economics. Context is an important consideration when one considers what behavior is rational and what behavior is not. Rather than use the term “irrational” to describe human beings, the authors assert that humans are “infinitely complex” and behavior that is often considered irrational is entirely situational.

Schoar, Antoinette and Saugato Datta. “The Power of Heuristics.” Ideas42. January 2014. https://bit.ly/2UDC5YK.

  • This paper explores the notion that being presented with a bevy of options can be desirable in many situations, but when making an intelligent decision requires a high-level understanding of the nuances of vastly different financial aid packages, for example, options can overwhelm. Heuristics (rules of thumb) provide helpful guidelines that “enable people to make ‘reasonably good’ decisions without needing to understand all the complex nuances of the situation.”
  • The underlying goal heuristics in the policy space involves giving people the type of “rules of thumb” that enable make good decisionmaking regarding complex topics such as finance, healthcare and education. The authors point to the benefit of asking individuals to remember smaller pieces of knowledge by referencing a series of studies conducted by psychologists Beatty and Kahneman that showed people were better able to remember long strings of numbers when they were broken into smaller segments.
  • Schoar and Datta recommend these four rules when implementing heuristics:
    • Use heuristics where possible, particularly in complex situation;
    • Leverage new technology (such as text messages and Internet-based tools) to implement heuristics.
    • Determine where heuristics can be used in adult training programs and replace in-depth training programs with heuristics where possible; and
    • Consider how to apply heuristics in situations where the exception is the rule. The authors point to the example of savings and credit card debt. In most instances, saving a portion of one’s income is a good rule of thumb. However, when one has high credit card debt, paying off debt could be preferable to building one’s savings.

Thaler, Richard H. and Cass R. Sunstein. Nudge: Improving Decisions About Health, Wealth, and Happiness. Yale University Press, 2008. https://bit.ly/2kNXroe.

  • This book, likely the single piece of scholarship most responsible for bringing the concept of nudges into the public consciousness, explores how a strategic “choice architecture” can help people make the best decisions.
  • Thaler and Sunstein, while advocating for the wider and more targeted use of nudges to help improve people’s lives without resorting to overly paternal regulation, look to five common nudges for lessons and inspiration:
    • The design of menus gets you to eat (and spend) more;
    • “Flies” in urinals improve, well, aim;
    • Credit card minimum payments affect repayment schedules;
    • Automatic savings programs increase savings rate; and
    • “Defaults” can improve rates of organ donation.
  • In the simplest terms, the authors propose the wider deployment of choice architectures that follow “the golden rule of libertarian paternalism: offer nudges that are most likely to help and least likely to inflict harm.”

U.K. Parliament Science and Technology Committee. “Behaviour Change.” July 2011. http://bit.ly/1cbYv5j.

  • This report from the U.K.’s Science and Technology Committee explores the government’s attempts to influence the behavior of its citizens through nudges, with a focus on comparing the effectiveness of nudges to that of regulatory interventions.
  • The author’s central conclusion is that, “non-regulatory measures used in isolation, including ‘nudges,’ are less likely to be effective. Effective policies often use a range of interventions.”
  • The report’s other major findings and recommendations are:
    • Government must invest in gathering more evidence about what measures work to influence population behaviour change;
    • They should appoint an independent Chief Social Scientist to provide them with robust and independent scientific advice;
    • The Government should take steps to implement a traffic light system of nutritional labelling on all food packaging; and
    • Current voluntary agreements with businesses in relation to public health have major failings. They are not a proportionate response to the scale of the problem of obesity and do not reflect the evidence about what will work to reduce obesity. If effective agreements cannot be reached, or if they show minimal benefit, the Government should pursue regulation.”

Unbundling the nation state

Curated on Posted on by Stefaan Verhulst

The Economist on Government-to-government trade: “NIGERIAN pineapple for breakfast, Peruvian quinoa for lunch and Japanese sushi for dinner. Two centuries ago, when David Ricardo advocated specialisation and free trade, the notion that international exchange in goods and services could make such a cosmopolitan diet commonplace would have seemed fanciful.
Today another scenario may appear equally unlikely: a Norwegian government agency managing Algeria’s sovereign-wealth fund; German police overseeing security in the streets of Mumbai; and Dubai playing the role of the courthouse of the Middle East. Yet such outlandish possibilities are more than likely if a new development fulfils its promise. Ever more governments are trading with each other, from advising lawmakers to managing entire services. They are following businesses, which have long outsourced much of what they do. Is this the dawn of the government-to-government era?
Such “G2G” trade is not new, though the name may be. After the Ottoman empire defaulted on its debt in 1875 foreign lenders set up an “Ottoman Public Debt Administration”, its governing council packed with European government officials. At its peak it had 9,000 employees, more than the empire’s finance ministry. And the legacy of enforced G2G trade—colonialism, as it was known—is still visible even today. Britain’s Privy Council is the highest court of appeal for many Commonwealth countries. France provides a monetary-policy service to several west African nations by managing their currency, the CFA franc.
One reason G2G trade is growing is that it is a natural extension of the trend for governments to pinch policies from each other. “Policymaking now routinely occurs in comparative terms,” says Jamie Peck of the University of British Columbia, who refers to G2G advice as “fast policy”. Since the late 1990s Mexico’s pioneering policy to make cash benefits for poor families conditional on things like getting children vaccinated and sending them to school has been copied by almost 50 other countries….Budget cuts can provide another impetus for G2G trade. The Dutch army recently sold its Leopard II tanks and now sends tank crews to train with German forces. That way it will be able to reform its tank squadrons quickly if they are needed. Britain, with a ten-year gap between scrapping old aircraft-carriers and buying new ones, has sent pilots to train with the American marines on the F-35B, which will fly from both American and British carriers.
…
No one knows the size of the G2G market. Governments rarely publicise deals, not least because they fear looking weak. And there are formidable barriers to trade. The biggest is the “Westphalian” view of sovereignty, says Stephen Krasner of Stanford University: that states should run their own affairs without foreign interference. In 2004 Papua New Guinea’s parliament passed a RAMSI-like delegation agreement, but local elites opposed it and courts eventually declared it unconstitutional. Honduras attempted to create independent “charter cities”, a concept developed by Paul Romer of New York University (NYU), whose citizens would have had the right of appeal to the supreme court of Mauritius. But in 2012 this scheme, too, was deemed unconstitutional.
Critics fret about accountability and democratic legitimacy. The 2005 Paris Declaration on Aid Effectiveness, endorsed by governments and aid agencies, made much of the need for developing countries to design their own development strategies. And providers open themselves to reputational risk. British police, for instance, have trained Bahraini ones. A heavy-handed crackdown by local forces during the Arab spring reflected badly on their foreign teachers…
When San Francisco decided to install wireless control systems for its streetlights, it posted a “call for solutions” on Citymart, an online marketplace for municipal projects. In 2012 it found a Swiss firm, Paradox Engineering, which had built such systems for local cities. But though members often share ideas, says Sascha Haselmayer, Citymart’s founder, most still decide to implement their chosen policies themselves.
Weak government services are the main reason poor countries fail to catch up with rich ones, says Mr Romer. One response is for people in poorly run places to move to well governed ones. Better would be to bring efficient government services to them. In a recent paper with Brandon Fuller, also of NYU, Mr Romer argues that either response would bring more benefits than further lowering the barriers to trade in privately provided goods and services. Firms have long outsourced activities, even core ones, to others that do them better. It is time governments followed suit.”

"Natural Cities" Emerge from Social Media Location Data

Curated on Posted on by Stefaan Verhulst

Emerging Technology From the arXiv: “Nobody agrees on how to define a city. But the emergence of “natural cities” from social media data sets may change that, say computational geographers…
A city is a large, permanent human settlement. But try and define it more carefully and you’ll soon run into trouble. A settlement that qualifies as a city in Sweden may not qualify in China, for example. And the reasons why one settlement is classified as a town while another as a city can sometimes seem almost arbitrary.
City planners know this problem well.  They tend to define cities by administrative, legal or even historical boundaries that have little logic to them. Indeed, the same city can sometimes be defined in various different ways.
That causes all kinds of problems from counting the total population to working out who pays for the upkeep of the place.  Which definition do you use?
Now help may be at hand thanks to the work of Bin Jiang and Yufan Miao at the University of Gävle in Sweden. These guys have found a way to use people’s location recorded by social media to define the boundaries of so-called natural cities which have a close resemblance to real cities in the US.
Jiang and Miao began with a dataset from the Brightkite social network, which was active between 2008 and 2010. The site encouraged users to log in with their location details so that they could see other users nearby. So the dataset consists of almost 3 million locations in the US and the dates on which they were logged.
To start off, Jiang and Miao simply placed a dot on a map at the location of each login. They then connected these dots to their neighbours to form triangles that end up covering the entire mainland US.
Next, they calculated the size of each triangle on the map and plotted this size distribution, which turns out to follow a power law. So there are lots of tiny triangles but only a few  large ones.
Finally, the calculated the average size of the triangles and then coloured in all those that were smaller than average. The coloured areas are “natural cities”, say Jiang and Miao.
It’s easy to imagine that resulting map of triangles is of little value.  But to the evident surprise of ther esearchers, it produces a pretty good approximation of the cities in the US. “We know little about why the procedure works so well but the resulting patterns suggest that the natural cities effectively capture the evolution of real cities,” they say.
That’s handy because it suddenly gives city planners a way to study and compare cities on a level playing field. It allows them to see how cities evolve and change over time too. And it gives them a way to analyse how cities in different parts of the world differ.
Of course, Jiang and Miao will want to find out why this approach reveals city structures in this way. That’s still something of a puzzle but the answer itself may provide an important insight into the nature of cities (or at least into the nature of this dataset).
A few days ago, this blog wrote about how a new science of cities is emerging from the analysis of big data.  This is another example and expect to see more.

‘Nudge Unit’ forming mutual joint venture

Curated on Posted on by Stefaan Verhulst

Press Release: “The government’s Behavioural Insights Team – also known as the Nudge Unit – has teamed up with Nesta, the UK’s innovation foundation, to create a new mutual joint venture, Minister for the Cabinet Office Francis Maude announced today.
The mutual joint venture will be a new UK-based company, paying taxes, exporting services across the world and helping get Britain on the rise.
The Behavioural Insights Team, which was set up in 2010 with a mission to find innovative ways of enabling people to make better choices for themselves and society, is now a world-leader in the application of insights from the behavioural sciences and credited with helping the UK government save millions of pounds for the taxpayer.
As a result, they have received an increasing number of requests to help apply insights from the behavioural sciences to tackle public policy problems, both at home and overseas. As of today, the team – which will continue to be known as the Behavioural Insights Team – is able to service this demand from any part of the UK public sector, charities and foreign governments. The new company will also be able to work with commercial organisations, where there is an underlying social purpose to the project….
The deal forms part of the government’s commitment to drive innovation in government commercial models – a central commitment in the Civil Service Reform Plan – and follows on from the launch of the civil service pension provider MyCSP in April 2012, which became the first mutual joint venture to spin out of government, and the launch of SSCL Ltd late last year in a joint venture with Steria Ltd to run shared services for Whitehall departments.
The government is determined to look beyond the old binary choice between in-house provision and outsourcing. As such they are working to develop a hybrid economy with a diverse range of suppliers from the mutual joint ventures to the voluntary sector, from in-house provision to straight sourcing.”

Community boxes let city residents share anything

Curated on Posted on by Stefaan Verhulst

Springwise: “While startups such as Boxbee aim to turn customers self storage assets into a shareable library of goods among friends, a new project in Switzerland is taking a similar concept into the public sphere. Boîtes d’Échange Entre Voisins — or Neighborhood Exchange Boxes — are a network of brightly-decorated repositories where residents can leave books, toys or other items they’d like to give to the community.
The idea, which was conceived by public art organization Tako in collaboration with the City of Geneva, is a fairly simple one — boxes big enough to hold objects such as books, DVDs, games and household items are installed in public locations. The boxes can be identified by their often artistic decorations bearing the name of the project. Any member of the public can then leave unwanted goods in the boxes for anyone else to take. The idea takes inspiration from schemes such as Bookcrossing and Little Free Library, which both focus more narrowly on book sharing. However, there is no restriction to what can be left in the project’s boxes, so long as it fits — users have even seen one generous neighbor leave an unwanted Apple TV.
There are currently around 20 Boîtes d’Échange Entre Voisins across Switzerland, and anyone can join in by setting up a box for their own neighborhood. Could this work in your part of the world?
