More Than Nudges Are Needed to End the Pandemic


Richard Thaler in the New York Times: “…In the case of Covid vaccinations, society cannot afford to wait decades. Although vaccines are readily available and free for everyone over age 12 in the United States, there are many holdouts. About 40 percent of the adult population has not been fully vaccinated, and about a third has not yet gotten even one dose. It is time to get serious.

Of course, information campaigns must continue to stress the safety and efficacy of the vaccines, but it is important to target the messages at the most hesitant groups. It would help if the F.D.A. gave the vaccines its full approval rather than the current emergency use designation. Full approval for the Pfizer drug may come as soon as Labor Day, but the process for the other vaccines is much further behind.

One way to increase vaccine takeup would be to offer monetary incentives. For example, President Biden has recently advocated paying people $100 to get their shots.

Although this policy is well intended, I believe it is a mistake for a state or a country to offer to pay individuals to get vaccinated. First of all, the amount might be taken to be an indicator of how much — or little — the government thinks getting a jab is worth. Surely the value to society of increased vaccinations is well beyond $100 per person.

Second, it seems increasingly likely that one or more booster shots may be necessary for some populations in the United States to deal with the Delta variant of the coronavirus — and, perhaps, other variants as well. If that happens, we don’t want some people to procrastinate, hoping to get paid. Government-sponsored booster shots are already beginning in Israel and are at various stages of planning in several European countries.

An alternative model is being offered by the National Football League, which has stopped short of requiring players to be vaccinated but is offering plenty of incentives. Unvaccinated players have to be tested every day, must be masked and at a distance from teammates on flights, and must stay in their room until game day. Vaccinated players who test positive and are asymptomatic can return to duty after two negative tests 24 hours apart. But unvaccinated players must undergo a 10-day isolation period.

These incentives followed a long effort to educate the players about the benefits to themselves, their families and fellow players. It is hard to say which aspect of the N.F.L. plan is doing the work, but over 90 percent of the league’s players have received at least one jab. The fact that a team could lose a game because an unvaccinated player can’t play creates a powerful group dynamic…(More)”.

Nudge: The Final Edition


Book by Richard H. Thaler and Cass R. Sunstein: “Since the original publication of Nudge more than a decade ago, the title has entered the vocabulary of businesspeople, policy makers, engaged citizens, and consumers everywhere. The book has given rise to more than 400 “nudge units” in governments around the world and countless groups of behavioral scientists in every part of the economy. It has taught us how to use thoughtful “choice architecture”—a concept the authors invented—to help us make better decisions for ourselves, our families, and our society.

Now, the authors have rewritten the book from cover to cover, making use of their experiences in and out of government over the past dozen years as well as an explosion of new research in numerous academic disciplines. To commit themselves to never undertaking this daunting task again, they are calling this the “final edition.” It offers a wealth of new insights, for both its avowed fans and newcomers to the field, about a wide variety of issues that we face in our daily lives—COVID-19, health, personal finance, retirement savings, credit card debt, home mortgages, medical care, organ donation, climate change, and “sludge” (paperwork and other nuisances we don’t want, and that keep us from getting what we do want)—all while honoring one of the cardinal rules of nudging: make it fun!…(More)”.

Behavioural science is unlikely to change the world without a heterogeneity revolution


Article by Christopher J. Bryan, Elizabeth Tipton & David S. Yeager: “In the past decade, behavioural science has gained influence in policymaking but suffered a crisis of confidence in the replicability of its findings. Here, we describe a nascent heterogeneity revolution that we believe these twin historical trends have triggered. This revolution will be defined by the recognition that most treatment effects are heterogeneous, so the variation in effect estimates across studies that defines the replication crisis is to be expected as long as heterogeneous effects are studied without a systematic approach to sampling and moderation. When studied systematically, heterogeneity can be leveraged to build more complete theories of causal mechanism that could inform nuanced and dependable guidance to policymakers. We recommend investment in shared research infrastructure to make it feasible to study behavioural interventions in heterogeneous and generalizable samples, and suggest low-cost steps researchers can take immediately to avoid being misled by heterogeneity and begin to learn from it instead….(More)”.

To solve big issues like climate change, we need to reframe our problems



Essay by Thomas Wedell-Wedellsborg and Jonathan Wichmann: “Imagine you own an office building and your tenants are complaining that the elevator is way too slow. What do you do?

Faced with this problem, most people instinctively jump into solution mode. How can we make the elevator faster? Can we upgrade the motor? Tweak the algorithm? Do we need to buy a new elevator?

The speed of the elevator might be the wrong problem to focus on, however. Talk to an experienced landlord and they might offer you a more elegant solution: put up mirrors next to the elevator so people don’t notice the wait. Gazing lovingly at your own reflection tends to have that effect.

The mirror doesn’t make the elevator faster. It solves a different problem – that the wait is annoying.

Solve the right problem

The slow elevator story highlights an important truth, in that the way we frame a problem often determines which solutions we come up with. By shifting the way we see a problem, we can sometimes find better solutions.

Problem framing is of paramount importance when it comes to tackling the many hard challenges our societies face. And yet, we’re not terribly good at it. In a survey of 106 corporate leaders, 87% said their people waste significant resources solving the wrong problems. When we go to the doctor, we know very well that identifying the right problem is key. Too often, we fail to apply the same thinking to social and global problems.

Three common patterns

So, how do we get better at it? One starting point is to recognise that there are often patterns in the way we frame problems. Get better at recognising those patterns, and you can dramatically improve your ability to solve the right problems. Here are three typical patterns:

1. We prefer framings that allow us to avoid change

People tend to frame problems so they don’t have to change their own behaviour. When the lack of women leading companies first became a prominent concern decades ago, it was often framed as a pipeline problem. Many corporate leaders simply assumed that, once there were enough women in junior positions, the C-suite would follow.

That framing allowed companies to carry on as usual for about a generation until time eventually proved the pipeline theory wrong, or at best radically incomplete. The gender balance among senior executives would surely be better by now if companies had not spent a few decades ignoring other explanations for the skewed ratio….(More)”.

Have behavioral sciences delivered on their promise to influence environmental policy and conservation practice?


Paper by Maria Alejandra Velez and Lina Moros: “After four decades of refining our understanding of decision-making processes, a form of consensus has developed around the crucial role that behavioral science can play in changing non-cooperative decisions and promoting pro-environmental behaviors. However, has behavioral science delivered on its promise to influence environmental policy and conservation practice? We discuss key lessons coming from studies into the dual process theory of thinking and the presence of cognitive biases, social norms and intrinsic motivations. We then discuss the empirical findings by reviewing relevant research published over the past five years, and identify emerging lessons. Recent studies focus on providing feedback, manipulating framing, using green nudges, or activating social norms on urban contexts, mainly energy and water. Interventions are needed in the context of common pool resources in the global south. We end by discussing the great potential for scaling-up programs and interventions, but there are still challenges for research and practice….(More)”

Human behaviour: what scientists have learned about it from the pandemic


Stephen Reicher at The Conversation: “During the pandemic, a lot of assumptions were made about how people behave. Many of those assumptions were wrong, and they led to disastrous policies.

Several governments worried that their pandemic restrictions would quickly lead to “behavioural fatigue” so that people would stop adhering to restrictions. In the UK, the prime minister’s former chief adviser Dominic Cummings recently admitted that this was the reason for not locking down the country sooner.

Meanwhile, former health secretary Matt Hancock revealed that the government’s failure to provide financial and other forms of support for people to self-isolate was down to their fear that the system “might be gamed”. He warned that people who tested positive may then falsely claim that they had been in contact with all their friends, so they could all get a payment.

These examples show just how deeply some governments distrust their citizens. As if the virus was not enough, the public was portrayed as an additional part of the problem. But is this an accurate view of human behaviour?

The distrust is based on two forms of reductionism – describing something complex in terms of its fundamental constituents. The first is limiting psychology to the characteristics – and more specifically the limitations – of individual minds. In this view the human psyche is inherently flawed, beset by biases that distort information. It is seen as incapable of dealing with complexity, probability and uncertainty – and tending to panic in a crisis.

This view is attractive to those in power. By emphasising the inability of people to govern themselves, it justifies the need for a government to look after them. Many governments subscribe to this view, having established so-called nudge units – behavioural science teams tasked with subtly manipulating people to make the “right” decisions, without them realising why, from eating less sugar to filing their taxes on time. But it is becoming increasingly clear that this approach is limited. As the pandemic has shown, it is particularly flawed when it comes to behaviour in a crisis.

In recent years, research has shown that the notion of people panicking in a crisis is something of a myth. People generally respond to crises in a measured and orderly way – they look after each other.

The key factor behind this behaviour is the emergence of a sense of shared identity. This extension of the self to include others helps us care for those around us and expect support from them. Resilience cannot be reduced to the qualities of individual people. It tends to be something that emerges in groups.

Another type of reductionism that governments adopt is “psychologism” – when you reduce the explanation of people’s behaviour to just psychology…(More)”.

The State of Global Emotions


Gallup: “Nobody was alone in feeling more sad, angry, worried or stressed last year. Gallup’s latest Negative Experience Index, which annually tracks these experiences worldwide in more than 100 countries and areas, shows that collectively, the world was feeling the worst it had in 15 years. The index score reached a new high of 32 in 2020.

Line graph. The Negative Experience Index, an annual composite index of stress, anger, worry, sadness and physical pain, continued to rise in 2020, hitting a new record of 32.

Gallup asked adults in 115 countries and areas if they had five specific negative experiences on the day preceding the survey. Four in 10 adults said they had experienced worry (40%) or stress (40%), and just under three in 10 had experienced physical pain (29%) during a lot of the previous day. About one in four or more experienced sadness (27%) or anger (24%).

Already at or near record highs in 2019, experiences of worry, stress, sadness and anger continued to gain steam and set new records in 2020. Worry and sadness each rose one percentage point, anger rose two, and stress rocketed up five. The percentage of adults worldwide who experienced pain was the only index item that declined — dropping two points after holding steady for several years at 31%.

But 2020 officially became the most stressful year in recent history. The five-point jump from 35% in 2019 to 40% in 2020 represents nearly 190 million more people globally who experienced stress during a lot of the previous day.

Line graph. Reported stress worldwide soared to a record 40% in 2020 amid the COVID-19 pandemic.

Worldwide, not everyone was feeling this stress to the same degree. Reported stress ranged from a high of 66% in Peru — which represents a new high for the country — to a low of 13% in Kyrgyzstan, where stress levels have historically been low and stayed low in 2020….(More)”

Fighting Climate Change: The Role of Norms, Preferences, and Moral Values


Paper by Armin Falk: “We document individual willingness to fight climate change and its behavioral determinants in a large representative sample of US adults. Willingness to fight climate change – as measured through an incentivized donation decision – is highly heterogeneous across the population. Individual beliefs about social norms, economic preferences such as patience and altruism, as well as universal moral values positively predict climate preferences. Moreover, we document systematic misperceptions of prevalent social norms. Respondents vastly underestimate the prevalence of climate- friendly behaviors and norms among their fellow citizens. Providing respondents with correct information causally raises individual willingness to fight climate change as well as individual support for climate policies. The effects are strongest for individuals who are skeptical about the existence and threat of global warming…(More)”.

Repository of Behavioral Interventions in Latin America and the Caribbean


Inter-American Development Bank (IDB): “How do you keep people from gathering with friends and family during a pandemic? How do you improve school attendance among preschoolers? How do you make sure taxpayers pay their fair share? These are some of the questions researchers seek to solve so countries can continue to grow and prosper. Many issues come down to human behavior and how the right policy tools can nudge people into doing things that will benefit themselves and society. A new repository collects these tools and the lessons learned from behavioral interventions in Latin America and the Caribbean, making them available for policymakers across the region and beyond.

For nearly a decade, the Inter-American Development Bank (IDB) has been working with local and national governments in the region to advance knowledge and expertise on individual and collective decision-making. The goal is to address biases that guide people’s behavior in detrimental ways. By designing strategies to correct them, we can help people make wiser choices in areas that range from education and savings to health, tax compliance, and labor markets….

To collect our findings and make the lessons we learned over the years available to policymakers and researchers, we recently created the largest online repository of quantitative behavioral economics field experiments conducted in Latin America and the Caribbean. The repository is aimed specifically at policymakers and is available in Spanish and English….(More)”.

How laws affect the perception of norms: empirical evidence from the lockdown


Paper by Roberto Galbiati, Emeric Henry, Nicolas Jacquemet, and Max Lobeck: “Laws not only affect behavior due to changes in material payoffs, but they may also change the perception individuals have of societal norms, either by shifting them directly or by providing information on these norms. Using detailed daily survey data and exploiting the introduction of lockdown measures in the UK in the context of the COVID-19 health crisis, we provide causal evidence that the law drastically changed the perception of the norms regarding social distancing behaviors. We show this effect of laws on perceived norms is mostly driven by an informational channel….(More)”.
