Nudges for Unrealistic Optimism

Nudges for Unrealistic Optimism

Posted on by jabittan
Our society makes fun of the unrealistic optimist all the time, but the reality is that most of us are unreasonably optimistic in many aspects of our life. We might not all believe that we are going to receive a financial windfall this month, that our favorite sports team will go from losing almost all their games last year to the championship this year, or that everyone in our family will suddenly be happy, but we still manage to be more optimistic about most things than is reasonable.

 

Most people believe they are better than average drivers, even though by definition half the people in a population must be above and half the people below average. Most of us probably think we will get a promotion or raise sometime sooner rather than later, and most of us probably think we will live to be 100 and won’t get cancer, go bald, or be in a serious car crash (after all, we are all above average drivers right?).

 

Our overconfidence is often necessary for daily life. If you are in sales, you need to be unrealistically optimistic that you are going to get a big sale, or you won’t continue to pick up the phone for cold calls. We would all prefer the surgeon who is more on the overconfident side than the surgeon who doubts their ability and asks us if we finalized our will before going into the operating room. And even just for going to the store, doing a favor for a neighbor, or paying for sports tickets, overconfidence is a feature, not a bug, of our thinking. But still, there are times where overconfidence can be a problem.

 

2020 is an excellent example. If we all think I’m not going to catch COVID, then we are less likely to take precautions and are more likely to actually catch the disease. This is where helpful nudges can come into play.

 

In Nudge, Cass Sunstein and Richard Thaler write, “If people are running risks because of unrealistic optimism, they might be able to benefit from a nudge. In fact, we have already mentioned one possibility: if people are reminded of a bad event, they may not continue to be so optimistic.”

 

Reminding people of others who have caught COVID might help encourage people to take appropriate safety precautions. Reminding a person trying to trade stocks of previous poor decisions might encourage them to make better investment choices then trying their hand at day trading. A quick pop-up from a website blocker might encourage someone not to risk checking social media while they are supposed to be working, saving them from the one time their supervisor walks by while they are scrolling through someone’s profile. Overconfidence may be necessary for us, but it can lead to risky behavior and can have serious downfalls. If slight nudges can help push people away from catastrophic consequences from unrealistic optimism, then they should be employed.
Nudges Versus Regulation

Nudges Versus Regulation

Posted on by jabittan
“Libertarian paternalism, we think, is a promising foundation for bipartisanship.” Write Cass Sunstein and Richard Thaler in their book Nudge. The authors are in favor of a governance structure that does not eliminate choice and possibility for people in the world. They are in favor of a system that allows flexibility for the people who have the time and capacity to consider all of their options before making a choice, and they prefer subtle and almost invisible forces to shape public opinion and behaviors. Throughout the book they argue that heavy handed regulation can be harmful to the long-term success and progress in some areas because people may push back against laws and regulations that limit freedom.  Nudges, in their view, can be an avenue toward real bipartisanship and cooperation because they can make real world changes without heavy handed government action.

 

The authors present the standard view of American politics where the Republican Party is presented as the party of small government while Democrats are the party of big government action. Republicans are all about freedom of choice and individual responsibility while Democrats are the party of government planning and the use of public institutions to improve people’s lives. I think this view is wrong. I think people are primarily self-interested, and gravitate toward the party that better reflects their identity, personality, and self-interests, and through motivated reasoning find high-minded excuses for supporting the party that generally aligns with the overarching political preferences that the standard view of American politics presents. But does this mean that Sunstein and Thaler are wrong about the ability of nudges to bring together Republicans and Democrats for action on public policy?

 

They write, “In many domains, including environmental protection, family law, and school choice, we will be arguing that better governance requires less in the way of government coercion and constraint, and more in the way of freedom to choose.”

 

When we consider whether Sunstein and Thaler are correct, we have to ask what is meant by better governance. Better governance might be reaching actual goals and actually improving people’s lives. It might mean creating a system that people are happier to interact with. Better governance may also mean a system that is more equitable, creates more social cohesion and trust, or that operates quicker. Each of these concepts is different, yet related, and we demonstrate that how we chose to measure better governance can shape the approaches we take. A focus on greater equity might come at the cost of quicker hiring and firing processes. Creating a system that leaves individuals who interact with governance happier may mean a system that is bigger and more expensive, but might not mean that it actually solves people’s problems. What we mean by better governance can conflict with what someone else means by better governance, so it is important to be clear about goals and expectations.

 

And that gets to the question – do nudges actually do any of these things? In terms of addressing environmental protection, I don’t think nudges are adequate. I think we are at a point where catastrophic environmental damage and climate change are unavoidable unless we have massive societal and technological changes. Simple nudges that tax oil and gas while offering rebates or incentives for purchasing electric cars won’t change the landscape quick enough to help mitigate climate change and create a sustainable world moving forward. I think we are at a point where we need real action to produce meaningful changes that lead to better governance in environmental policy. It might be time for outright bans on sales of gasoline and diesel engines, billion dollar prizes for green technology, and other heavy handed government interferences in markets and people’s daily lives.

 

However, within family policy, nudges do seem like they can be meaningful. Tyler Cowen recently shared research correlating child car safety laws with the number of children a family has. The argument being that car seats and seat-belt requirements may make it more difficult to have multiple young children who take a long time to get situated in a car before driving, reducing incentives for parents to have more kids. Family decisions, it seems, can be highly influenced by seemingly inconsequential factors. If this is accurate, then nudges, such as child care rebates, really might reduce the costs of childbearing, and might encourage larger families, shaping the actual outcome of people’s lives and securing a young tax base to support social service programs. Nudges might be an effective approach to encouraging more family formation.

 

To continue analyzing policy in areas where Sunstein and Thaler’s quote suggests nudges would be helpful, my argument on school choice would be that it is effectively 100% signaling and self-interest. Religious parents probably don’t care too much about what their children actually learn in school or where they go. They do care about how much their school choice argument and energy demonstrate their religious devotion. Wealthy parents care about the signaling power of elite schools and universities, and similarly care about how much their children will be able to signal and benefit from a private school education that is out of reach for the majority of families who send their children to public schools. Race, socio-economic status, and other identity markers seem to be core to the self-interest of most school choice freedom advocates in my opinion. From my point of view, better governance would enhance social cohesion, encourage more opportunities for those individuals who otherwise would be left out, and help us manage diversity collectively. If school choice is overwhelmingly dominated by signaling and self-interest, then I see little reason why nudges would be the best approach to shaping policy. Nudges that increase costs of signaling end up creating stronger signals for those who can afford to still send their children to private institutions, therefore increasing their value and creating more division and contention within the debate.

 

Nudges seem to have real power in shaping public policy and can likely bring together Republicans and Democrats in some instances, but if governance is not about public policy, but is instead about identity, self-interest, and signaling, then I don’t think nudges can truly do much to improve governance or bring together Democrats and Republicans. Similarly, for massively consequential policy areas, I don’t think we can leave our future and success up to nudges. They may take too long and not be forceful enough to really shape public behavior and attitude, especially if they face entrenched opposition.
Nudges Are Unavoidable - Joe Abittan

Nudges Are Unavoidable

Posted on by jabittan
American capitalism makes a mistake in assuming that people have all the information they need to make a rational choice. As anyone who has ever purchased a car knows, consumers do not always have all the valuable information they need to make a good decision in an exchange, and often, one party has far more information than another. We can become experts at selecting avocados pretty easily, but it is fairly unlikely that we will become experts at selecting the best used car. We become avocado experts because we can buy them weekly and get reliable and immediate feedback when we get home and cut into them. A used car, however, is not something we buy on a regular basis, and we might make it months or years before we have a catastrophic break down.

 

Because we are not experts in everything and because there are some decisions we have to make where we don’t get reliable and timely feedback and can’t practice enough to truly know what to look for, we are subject to forces large and small that influence our decision-making. Buying a used car because you like the sales person, because the price feels right, and because of brand loyalty are examples of cognitive errors or biases where subtle nudges by the dealership or brand can influence us. Whether a salesman intends it or not, there are many factors that nudge our behavior, and they can’t be eliminated.

 

In Nudge, Cass Sunstein and Richard Thaler write, “In many situations, some organization or agent must make a choice that will affect the behavior of some other people. There is, in those situations, no way of avoiding nudging in some direction, and whether intended or not, these nudges will affect what people chose.”

 

The car dealership example is a somewhat nefarious and depressing view of nudges. However, the reality of Sunstein and Thaler’s quote can also be a powerful force to help improve people’s lives and not just overcharge them for a lemon. Carfax is a company that helps nudge people in the right direction, by getting them to consider the vehicle’s collision history before making a decision based on how shiny the car looks. Other nudges can be helpful for people, and if we accept that nudges are unavoidable, then we can actively step in to help design decision situations in a way that will allow people to make good decisions. An example I can think of would be visual aids to help people understand how much they can afford for a monthly car payment, mortgage, or rent. Most housing agencies suggest that people shouldn’t spend more than 33% of their monthly income on rent/mortgage. A calculator tool with a green smiley face, and a red frown face could help nudge people away from mortgages or rents that they really can’t afford, helping people make difficult and more reasonable housing decisions. Small actions can help people better understand their decisions and can serve as guides that help people do what is actually in their best interest as they themselves would understand it.
Paternalistic Nudges - Joe Abittan

Paternalistic Nudges

Posted on by jabittan
In their book Nudge, Cass Sunstein and Richard Thaler argue in favor of libertarian paternalism. Their argument is that our world is complex and interconnected, and it is impossible for people to truly make decisions on their own. Not only is it impossible for people to simply make their own decisions, it is impossible for other people to avoid influencing the decisions of others. Whether we decide to influence a decision in a particular way, or whether we decide to try to avoid any influence on another’s decision, we still shape how decisions are presented, understood, and contextualized. Given this reality, the best alternative is to try to help people make consistently better decisions than they would without aid and assistance.

 

The authors describe libertarian paternalism by writing:

 

“The approach we recommend does count as paternalistic, because private and public choice architects are not merely trying to track or to implement people’s anticipated choices. Rather, they are self-consciously attempting to move people in directions that will make their lives better. They nudge.”

 

The nudge is the key aspect of libertarian paternalism. Forcing people into a single choice, forcing them to accept your advice and perspective, and aggressively trying to change people’s behaviors and opinions doesn’t fit within the libertarian paternalism framework advocated by Sunstein and Thaler. Instead, a more subtle form of guidance toward good decisions is employed. People retain maximal choices if desired, and their opinions, decisions, and behaviors are somewhat constrained but almost nothing is completely off the table.

 

“A nudge,” Sunstein and Thaler write, “as we will use the term, is any aspect of the choice architecture that alters people’s behavior in a predictable way without forbidding any options or significantly changing their economic incentives.”

 

Daniel Kahneman, in his book Thinking Fast and Slow demonstrated that people make predictable errors and have predictable biases. If we can understand these thinking errors and biases, then we can identify situations in which these biases and cognitive errors are likely to lead people to making suboptimal decisions. To go a step further, as Sunstein and Thaler would suggest, if we are a choice architect, we should design and structure choices in a way that leads people away from predictable cognitive biases and errors. We should design choices in a way that takes those thinking mistakes into consideration and improves the way people understand their choices and options.

 

As a real world example, if we are structuring a retirement savings plan, we can be relatively sure that people will anchor around a default contribution built into their retirement savings plan. If we want to encourage greater retirement savings (knowing that economic data indicate people rarely save enough), we can set the default to 8% or higher, knowing that people may reduce the default rate, but likely won’t eliminate contributions entirely. Setting a high default is a nudge toward better retirement saving. We could chose not to have a default rate at all, and it is likely that people wouldn’t be sure about what rate to select and might chose a low rate below inflation or simply chose not to enter a rate at all, completely failing to contribute anything to the plan. It is clear that there is a better outcome that we, as choice architects, could help people attain if we understand how their minds work and can apply a subtle nudge.
The Power of Inertia - Joe Abittan

The Power of Inertia

Posted on by jabittan
For Richard Thaler and Cass Sunstein, inertia plays a critical role in the idea of using nudges to influence people toward making good decisions. Particularly in regard to default choices, inertia matters a lot. People accept defaults, and making any change, whether it is trivial, important, time consuming, or very simple, is stubbornly resisted by many people. Think about how likely you are to change your desktop background, to change your phone’s ringtone, to order something new at your usual Tuesday night restaurant, to fix the broken windshield visor in your car, or to change your weekend morning routine.

 

Once people develop a status quo, once a default has been set, the power of inertia sets in. Sunstein and Thaler in Nudge write, “First, never underestimate the power of inertia. Second, that power can be harnessed.”

 

Harnessing the power of inertia can be sinister, but for Sunstein and Thaler, that is not the point. When a company offers you a free three month trial if you use a credit card to sign-up, they are counting on making money off your inertia. However, when a state organ donation program auto-enrolls every who applies for a drivers license, they are counting on inertia to help save lives. Inertia can be leveraged not just to make money off lazy and forgetful people, but to help make life simpler, easier, and even longer for people. In our individual lives we can harness inertia to build a workout routine, to stop buying cookies at the store, and to eat an apple during our 15 minute break every morning. For public officials, inertia can be harnessed when public programs make it easy for people to register to vote, to automatically receive social services, and to pay taxes.

 

Companies who count of people forgetting to cancel a subscription after a free trial and companies who expect that people won’t spend time shopping for alternatives once they sign up for monthly services give the power of inertia a bad reputation. They make it hard for public agencies and elected officials to credibly discuss programs designed to take advantage of or at least acknowledge people’s inability to escape inertia. But this should be a serious discussion in public policy. It is important to think about whether people will make changes in their lives to adopt measures that will help them be more safe, live healthier, and cooperate better. When we see a clear preference in how we want people to interact, we should discuss ways to help people behave as we wish they would, if we can recognize a particular decision is what people would chose for themselves if they were to make the effort of choosing anything at all. We don’t have to eliminate choices or bar people from behave otherwise, but we can use nudges, defaults, and the power of inertia to help people make and stick with better choices.
Should We Assume Rationality?

Should We Assume Rationality?

Posted on by jabittan
The world is a complex place and people have to make a lot of decisions within that complexity. Whether we are deliberate about it or not, we create and manage systems and structures for navigating the complexity and framing the decisions we make. However, each of us operate from different perspectives. We make decisions that seem reasonable and rational from our individual point of view, but from the outside may seem irrational. The question is, should we assume rationality in ourselves and others? Should we think that we and other people are behaving irrationally when our choices seem to go against our own interests or should we assume that people have a good reason to do what they do?

 

This is a current debate and challenge in the world of economics and has been a long standing and historical debate in the world of politics. In his book Thinking Fast and Slow, Daniel Kahneman seems to take the stance that people are acting rationally, at least from their own point of view. He writes, “when we observe people acting in ways that seem odd, we should first examine the possibility that they have a good reason to do what they do.”

 

Rational decision-making involves understanding a lot of risk. It involves processing lots of data points, having full knowledge of our choices and the potential outcomes we might face, as well as thinking through the short and long-term consequences of our actions. Kahneman might argue, it would seem after reading his book, that truly rational thinking is beyond what our brains are ordinarily capable of managing. But to him, this doesn’t mean that people cannot still make rational choices and do what is in their best interests. When we see behaviors that seem odd, it is possible that the choices other people have made are still rational, but just require a different perspective.

 

The way people get to rationality, Thinking Fast and Slow suggests, is through heuristics that create shortcuts to decision-making and eliminate data that is more or less just noise. Markets can be thought of as heuristics in this way, allowing people to aggregate decisions and make choices with an invisible hand directing them toward rationality. So when we see people who seem to be acting obviously irrationally or opposed to their self-interest, we should ask whether they are making choices within an entirely different marketplace. What seems like odd behavior from the outside might be savvy signaling to a group we are not part of, might be a short term indulgence that will stand out to the remembering self in the long run, and might make sense if we can change the perspective through which we judge another person.

 

Kahneman shows that we can predict biases and patterns of thought in ourselves and others, but still, we don’t know exactly what heuristics and thinking structures are involved in other people’s decision-making. A charitable way to look at people is to assume their decisions are rational from where they stand and in line with the goals they hold, even if the choices they make do not appear to be rational to us from the outside.

 

Personally, I am on the side that doubts human rationality. While it is useful, empathetic, and humanizing to assume rationality, I think it can be a mistake, especially if we go too far in accepting the perspective of others as justification for their acts. I think that there are simply too many variables and too much information for us to truly make rational decisions or to fully understand the choices of others. My thinking is influenced by Kevin Simler and Robin Hanson who argue in The Elephant in the Brain, that we act on pure self-interest to a greater extent than we would ever admit, and we hide our self-interested behaviors and decisions from everyone, including ourselves.

 

At the same time, I do believe that we can set up systems, structures, and institutions that can help us make more rational decisions. Sunstein and Thaler, in Nudge, clearly show that markets can work and that people can be rational, but often need proper incentives and easy choice structures that encourage to encourage better choices. Gigerenzer in Risk Savvy ends up at a similar place, showing that we can get ahead of the brain’s heuristics and biases to produce rational thought. Creating the right frames, offering the right visual aids, and helping the brain focus on the relevant information can lead to rational thought, but nevertheless, as Kahneman shows, our thinking can still be hijacked and derailed, leading to choices that feel rational from the inside, but appear to violate what would be in our best interest when our decisions are stacked and combined over time. Ultimately, the greatest power in assuming rationality in others is that it helps us understand multiple perspectives, and might help us understand what nudges might help people change their behaviors and decisions to be more rational.

How to Describe a Norm

Posted on by jabittan
What inputs drive what types of behaviors in humans? This is a question I think about at an incredibly basic level all the time, but that I don’t really hear much insightful discussion about in general. We all like to believe we (and everyone else) is in complete conscious control of our thoughts, minds, and decisions all the time, but we know that can’t be true. If you leave someone in a room with a plate of freshly baked cookies in front of them, they will almost invariably eat a cookie, even if they had woken up that day determined not to eat any cookies. If you deprive someone of sleep for a whole day while they travel across the country from Seattle to Orlando with multiple layovers and tired and cranky kids, you are bound to hear a few exasperated yells, even if that person was determined not to yell at their children (or anyone else). At  a certain point, the inputs that make their way into our mind have a big influence on the resulting behaviors that we see in the world.

 

Norms are one way that we establish certain inputs associated with certain behaviors. They help us regulate what kinds of behaviors are acceptable and desired. As Kevin Simler and Robin Hanson write in The Elephant in the Brain, “The essence of a norm then, lies not in the words we use to describe it, but in which behaviors get punish and what form the punishment takes.” Norms are guidelines for nudging behaviors by changing the inputs into the minds of individuals.

 

We can applaud, ignore, or punish a behavior to change the likelihood of an action taking place again. If I send out a tweet with terrible insults, and that tweet is re-tweeted and I receive encouragement for speaking out against the people I insulted, I am receiving cues that suggest I should do more of that. If however, I see an old lady walking to the register at the grocery store, and I use my youthful speed to quickly jump in front of her, I am likely to receive angry looks and possibly be forced out of line if a big enough person sees me jump ahead of the little old lady. If the punishment in this situation is embarrassing enough, I likely won’t repeat this behavior the next time I am at the store.

 

Our minds and, consequently it seems, our brains are changed by the norms we use. What is possible in our wold is shaped by how we know other people will respond to what we do. The agency we feel when we think about the world is constrained by the thoughts, looks, and actions of other people. We rarely talk about all the inputs that may change our thinking and decision-making, but it is clear that we operate in a space where many physical and non-physical things can shape what we do, believe, and think. The mind absorbs many inputs and we are not always at liberty to decide how we will respond to those inputs if we are constrained or encouraged by specific norms.
