Which comes first on a mass scale: electric cars or driverless cars?

The car of the future could be quite different but what exactly it will be is still up in the air. Will it be an electric car? We need some significant infrastructure for that to work:

But here’s the thing. As a piece of new driving technology, the Bolt totally works. But the adoption curves and take-up rates of new technologies aren’t driven simply by the efficacy of the technology in and of itself. New innovations require infrastructure to reach their full market potential. Often that infrastructure has to be built by companies other than those who build the original products. And right now, electric cars remain hindered by a massive infrastructure gap…

Tesla has dealt with the infrastructure challenge by building its own network of proprietary superchargers—stations that only Tesla owners can use. But it’s a closed system, and it is part of what makes Tesla a luxury product. Non-Tesla users are out of luck. And while some of the big automakers are establishing partnerships with charging networks, none has taken it upon itself to build the dense, easily accessible, and highly functional network of charging stations that is needed. So it’s great that the Bolt feels like it belongs in everyone’s garage. But until that gaping infrastructure gap is bridged, it won’t be in nearly as many as it could be.

And working out all the kinks of driverless cars and then making them affordable to the mass market may take a while:

Despite technological advances, accidents like these reduce consumer trust and send companies back a few steps. A true autonomous future is perhaps as far away as 50 years, considering all that needs to happen to ensure safety and prepare the average driver.

While one will see the occasional driverless car zipping tech execs around Silicon Valley, new connected cars will still be out of reach for most families.

The internal combustion engine vehicle with a human driver may prove to have quite the staying power. How about we envision the electric self-driving vehicle for all several decades down the line?

Another thought: given all that would need to be done to completely switch over to either option, could the money and time be better spent on other problems?

Atlanta bridge collapses, traffic isn’t that bad

Urban highways are often very busy but when they are completely out of commission, it doesn’t necessarily lead to horrific traffic:

You’ll forgive our excessively clinical attitude about this damage—and it’s going to cost tens of millions to fix—but what we have here is a classic “natural experiment” of the kind economists and students of public policy relish. So what happens when we take a major urban freeway out of service for a couple of months? Are Atlanta commuters in for hours of gridlock every day and grisly commutes? Will the region’s economy grind to a halt as a result? We’ll be watching over the next several months to see.

So far, the results are consistent with what we’ve seen in Los Angeles and Minneapolis. Monday morning came, and something funny happened: traffic wasn’t so bad

So what’s going on here? Arguably, our mental model of traffic is just wrong. We tend to think of traffic volumes, and trip-making generally as inexorable forces of nature. The diurnal flow of 250,000 vehicles a day on an urban freeway like I-85 is just as regular and predictable as the tides. What this misses is that there’s a deep behavioral basis to travel. Human beings will shift their behavior in response to changing circumstances. If road capacity is impaired, many people can decide not to travel, change when they travel, change where they travel, or even change their mode of travel. The fact that Carmageddon almost never comes is powerful evidence of induced demand: people travel on roadways because the capacity is available for their trips, and when the capacity goes away, so does much of the trip making.

If Atlanta can survive for a month or two without a major chunk of its freeway, that’s a powerful indication that more modest steps to alter road capacity don’t really mean the end of the world. If we recognize that traffic will tend to adjust to available capacity, we then end up taking a different view of how to balance transportation against other objectives. For example, this ought to be a signal that road diets, which have been shown to greatly improve safety and encourage walking and cycling, don’t have anything approaching the kinds of adverse effects on travel that highway engineers usually predict.

I do think that this suggests drivers will adjust their behaviors based on what roads are available. At the same time, there is probably a tipping point where reducing too much traffic capacity would make a big difference. This might be especially true in car-driven places like Atlanta and Los Angeles that are known for sprawl. Presumably, places where traffic capacity could be picked up by other transportation options (such as closing the Embarcadero Freeway in San Francisco where driving is already a hassle and other options include BART, Muni, etc.) would fare better. Or, perhaps road capacity has to be reduced gradually so that people have time to adjust and make new choices about travel and where they live and work.

Nudging people for good or evil

Like much in today’s polarized world, perhaps you only like nudging when people are being moved in a direction you agree with:

We are living in an age in which the behavioral sciences have become inescapable. The findings of social psychology and behavioral economics are being employed to determine the news we read, the products we buy, the cultural and intellectual spheres we inhabit, and the human networks, online and in real life, of which we are a part. Aspects of human societies that were formerly guided by habit and tradition, or spontaneity and whim, are now increasingly the intended or unintended consequences of decisions made on the basis of scientific theories of the human mind and human well-being.

The behavioral techniques that are being employed by governments and private corporations do not appeal to our reason; they do not seek to persuade us consciously with information and argument. Rather, these techniques change behavior by appealing to our nonrational motivations, our emotional triggers and unconscious biases. If psychologists could possess a systematic understanding of these nonrational motivations they would have the power to influence the smallest aspects of our lives and the largest aspects of our societies…

But in spite of revealing these deep flaws in our thinking, Lewis supplies a consistently redemptive narrative, insisting that this new psychological knowledge permits us to compensate for human irrationality in ways that can improve human well-being. The field of behavioral economics, a subject pioneered by Richard Thaler and rooted in the work of Kahneman and Tversky, has taken up the task of figuring out how to turn us into better versions of ourselves. If the availability heuristic encourages people to ensure against very unlikely occurrences, “nudges” such as providing vivid reminders of more likely bad outcomes can be used to make their judgments of probability more realistic. If a bias toward the status quo means that people tend not to make changes that would benefit them, for instance by refusing to choose between retirement plans, we can make the more beneficial option available by automatically enrolling people in a plan with the option to withdraw if they choose…

Lewis does not discuss the ways in which the same behavioral science can be used quite deliberately for the purposes of deception and manipulation, though this has been one of its most important applications. Frank Babetski, a CIA Directorate of Intelligence analyst who also holds the Analytical Tradecraft chair at the Sherman Kent School of Intelligence Analysis at the CIA University, has called Kahneman’s Thinking, Fast and Slow a “must read” for intelligence officers.

This seems like a reasonable point – people can be pushed toward positive and negative behavior – but it still leaves a crucial question: who gets to decide what is worth pushing people toward? Is it manipulation when it goes a direction you don’t want but progress when it goes your way? The two major examples of this playing out in society don’t help much; we may wish that big corporations and national politicians have less ability to sway people but this is also part of having a lot of power. (Similarly, power can be used to benefit people or harm them.) Are we more okay with an individual having biases rather than larger social actors (who can coerce a lot more people at the same time)? If so, then it may be harder to have a large society that functions well.

In one decade, major suburban areas go from lowest drug overdose rates to highest

A new report details the rise of drug overdose deaths in suburbs:

Released Wednesday, the Robert Wood Johnson Foundation’s 2017 County Health Rankings and an accompanying report analyze county-level data from all 50 states on more than 30 public health outcomes and behaviors. The report finds there’s been a clear flip in the geography of addiction: One decade ago, large suburban areas experienced the lowest rates of premature deaths due to drug overdoses. In 2015, they had the highest.

The Johnson Foundation’s analysis doesn’t pinpoint which counties experienced the most dramatic gains in drug-induced death. What it does is rank every county in the U.S., by state, using data that reflects local health conditions, such as diabetes and obesity, as well as measures that can predict health outcomes, including teen birth, smoking rates, and grocery store access…

Comparing those numbers to the Johnson Foundation report, I found startling disconnects between deadly drug problems and places that have an otherwise fairly “healthy” facade. For example, Essex County ranks sixth out of the 14 counties in the Bay State by the new report—middle-of-the-road when it comes to the chronic health conditions that normally wave red flags for public health researchers. Yet it’s increasingly afflicted by drug-related deaths.

On the fringes of Cincinnati, Boone County, Kentucky, ranks first out of 120 across its state on all other health rankings. As in Essex County, rates of diabetes, smoking, and teen births are relatively low; poverty is suppressed, and employment is solid. Yet a look at CDC data shows county saw its drug-related death rate leap from 26 in 2010 to nearly 46 in 2015. Ranked smack in the middle of Ohio’s 88 counties and also included in the Cincinnati metro area, Clermont County saw a similar leap. Another example: Clay County, part of the Jacksonville, Florida, metro area, is 11th of the Sunshine State’s 67 counties. But drug-related deaths increased from 14 in 2010 to 23 in 2015.

It has been interesting thus far and it will continue to be interesting to observe how this is treated by the media, government, and public. This would be a good case for studying how a social problem develops: American society is so large that not everything can receive the attention it deserves. For example, how do the reactions to suburban drugs differ to how Americans treat drug use in cities (or rural areas which rarely get any attention)? How is the drug use explained: as part of criminal activity, irresponsibility, broken down homes and/or neighborhoods, wealth, or addiction? Because these deaths are happening to suburbanites – who as this article notes, are supposed to be healthier and often are – the story will be different.

Closing on a house feels like…

Based on my limited experience and scholarly interests, here are some possibilities for what closing on a house can be:

Fulfilling the American Dream of homeownership. On the positive side, owning your own property and providing space for a family. On the less positive side, establishing your class status.

-Agreeing to a sizable debt to a large financial institution. On one hand, you probably couldn’t buy that home without a long mortgage (thank goodness for the 30 year loan). On the other hand, you don’t really own your property for a long time and those mortgage payments just keep coming. Overall, a home is going to be the single largest investment/outlay of money for many.

-The end of a complicated process. I’ve seen several surveys suggesting many Americans dislike applying for mortgages (here is one example). It is one of those things in life many people don’t do more than a few times and it often requires a lot of paperwork (both to submit and to read).

-The start of a new era. (1) Even with the mobility of Americans and our relatively low attachment to places, we get used to the physical structures in which we live. (2) A new home often means new social arrangements as we navigate changing families and new neighborhoods and communities.

-Keeping another house occupied. Obviously, no one wants a lot of vacant properties – with lots of discussions of this in recent years involving foreclosures and particular locations like Detroit – but we can push the idea further: just how long will American homes last? Will post-war suburban homes be worth rehabbing when they hit 40-80 years of existence?

-Helping a community continue to exist. With your home purchase, you are making a commitment, if not socially (you could just retreat to the private world of your new home), then at least through your taxes. Even if we put too much emphasis on high population growth as a sign of success, communities can’t afford to lose too many residents and taxpayers.

Putting a price tag on Chicago’s segregation

A new report from the Metropolitan Planning Council and the Urban Institute suggests Chicago pays a high price for segregation:

The seven-county area’s murder rate could be cut by 30 percent, its economy could churn out an additional $8 billion in goods and services and its African-American residents could earn another $3,000 a year if it could reduce racial and economic segregation to the median level for the nation’s largest metro areas.

And 83,000 more residents could have earned bachelor’s degrees, spurring another $90 billion in collective lifetime earnings…

While the seven-county region has seen a slow reduction in racial and economic segregation between 1990 and 2010, it remained fifth-worst among the nation’s 100 most populous metro areas in 2010, the most recent full census year, the study found. The region includes Cook, DuPage, Lake, Kane, Kendall, McHenry and Will counties.

While segregation might benefit some – typically those who already have power and resources – this study suggests it harms the whole. Viewing issues of race, class, and gender might come down to these different perspectives of society: is it a zero-sum game where someone must lose for others to get ahead or can the pie be made bigger for everyone to share from? Take, for example, a period of history that is often held up as a good one for the entire country. The decades following World War II involved economic growth for most Americans as well as social change (Civil Rights, addressing poverty in cities and rural areas, the Great Society, etc.). We can’t recreate that period – it was contingent on a variety of other factors including winning World War II (and decimated economies elsewhere in the world) and the pent-up demand for many things after both a major war and the biggest global depression – but we could aim for policies that would help many people at all.

Las Vegas willing to pay record public subsidy to have NFL

How much power does the NFL have? Enough to have major cities commit incredible sums of public monies:

Las Vegas appears poised to claim the mantle of World’s Most Expensive Stadium from East Rutherford, New Jersey, where the Jets and Giants play in the $1.6 billion MetLife Stadium. (Los Angeles Stadium, Stan Kroenke’s project that will host the Rams and Chargers, is estimated at $2.6 billion—but that cost includes parts of the surrounding entertainment district.*)

Clark County taxpayers will contribute $750 million to the new arena, a record for a sports facility—about $354 per resident, taken from an increased tax on hotel rooms. That tax currently pays for schools and transportation, in addition to tourism-related expenditures.

Stanford economist Roger Noll said it was the “worst deal for a city” he had ever seen…

The state’s figures to justify that new tax are… ambitious. Its forecasts suggest 450,000 new visitors every year drawn by the 65,000-seat stadium, spending an average of 3.2 nights per visit. About a third of tickets are supposed to be purchased by tourists, although no other city manages 10 percent. Why half a million people would fly across the country to watch a team that no one wants to pay $20 to see in Oakland is not clear.

Even with the studies that show stadiums don’t contribute anything to cities, it seems that someone is always willing to pay. In this case, it wasn’t just Las Vegas: Oakland tried to put together a last-minute deal that they claimed would require even less of the team:

Schaaf told ESPN Friday she believes Oakland’s new stadium plan is viable.

“At the end of the day, this is the decision of the Raiders and the NFL,” Schaaf said. “What I am confident about is, if the Raiders want to stay in Oakland, we have a viable plan to build them a stadium with no upfront money from them, in financial terms that I believe are more favorable to them than the terms in Las Vegas — what we know of them.”

I’m still waiting for a city mayor or other big-name official to publicly bid a major sports franchise good riddance when they ask for a lot of local money. Perhaps that would be bad form – local officials are usually in the business of trying to attract everyone they can – but it could also send a strong signal about how private interests cannot overrule the long-term public interest.

Using a GRIM method to find unlikely published results

Discovering which published studies may be incorrect or fraudulent takes some work and here is a newer tool: GRIM.

GRIM is the acronym for Granularity-Related Inconsistency of Means, a mathematical method that determines whether an average reported in a scientific paper is consistent with the reported sample size and number of items. Here’s a less-technical answer: GRIM is a B.S. detector. The method is based on the simple insight that only certain averages are possible given certain sets of numbers. So if a researcher reports an average that isn’t possible, given the relevant data, then that researcher either (a) made a mistake or (b) is making things up.

GRIM is the brainchild of Nick Brown and James Heathers, who published a paper last year in Social Psychological and Personality Science explaining the method. Using GRIM, they examined 260 psychology papers that appeared in well-regarded journals and found that, of the ones that provided enough necessary data to check, half contained at least one mathematical inconsistency. One in five had multiple inconsistencies. The majority of those, Brown points out, are “honest errors or slightly sloppy reporting.”…

After spotting the Wansink post, Anaya took the numbers in the papers and — to coin a verb — GRIMMED them. The program found that the four papers based on the Italian buffet data were shot through with impossible math. If GRIM was an actual machine, rather than a humble piece of code, its alarms would have been blaring. “This lights up like a Christmas tree,” Brown said after highlighting on his computer screen the errors Anaya had identified…

Anaya, along with Brown and Tim van der Zee, a graduate student at Leiden University, also in the Netherlands, wrote a paper pointing out the 150 or so GRIM inconsistencies in those four Italian-restaurant papers that Wansink co-authored. They found discrepancies between the papers, even though they’re obviously drawn from the same dataset, and discrepancies within the individual papers. It didn’t look good. They drafted the paper using Twitter direct messages and titled it, memorably, “Statistical heartburn: An attempt to digest four pizza publications from the Cornell Food and Brand Lab.”

I wonder how long it will be before journals employ such methods for submitted manuscripts. Imagine Turnitin for academic studies. Then, what would happen to authors if problems are found?

It also sounds like a program like this could make it easy to do mass analysis of published studies to help answer questions like how many findings are fraudulent.

Perhaps it is too easy to ask whether GRIM has been vetted by outside persons…

CHA’s Plan for Transformation didn’t transform public housing much

A new report from WBEZ suggests the Chicago’s Plan for Transformation has not met its goals:

Now, more than 17 years and $3 billion later, only 7.81 percent of the 16,846 households under the Plan For Transformation live in mixed-income communities, according to data from the CHA obtained under the Illinois Freedom of Information Act through a joint study by WBEZ and Northwestern University’s Medill Social Justice News Nexus.

The rest of the households?

  • 20.81 percent live on a Housing Choice or Section 8 voucher
  • 15.97 percent live in traditional public housing
  • 11.99 percent were evicted
  • 9.59 percent have died

The remaining 33.82 percent are living without a government subsidy.

The Plan For Transformation is the largest remake of public housing in the nation. It has simultaneously produced new communities and tracts of vacant land, gentrification and segregation throughout the city.

Arguably, the most “successful” part of the Plan for Transformation was limiting the visibility of public housing  by demolishing high-rise buildings. But, that did little to help the public housing residents or the neighborhoods in which the high-rises were located (Cabrini-Green is an exception because it was already located near wealthier and whiter residents). All that money and effort…could it have worked out better if it (1) wasn’t managed by the CHA (which has a poor record over decades of providing public housing) or (2) wasn’t located in Chicago (the one Rust Belt city that has supposedly made it but still has serious problems including residential segregation)? Efforts elsewhere have also been mixed – leading to the thought that perhaps the federal government can’t do much in this area. This doesn’t mean that the idea of public housing is worthless but maybe that issues of race, class, and residential segregation are really difficult to overcome.

Does the population size of the US get in the way?

One idea I’ve had in my mind in recent years is how the population size of the United States interacts with the country’s stated ideals and policies. Is it possible to be the United States with over 320 million residents? When I hear discussions of policy, I am regularly struck by the size of the issue at hand. Healthcare is a good example. Any changes at the Federal level – whether adding to existing policies or retracting what currently exists – would have significant impact on millions of people as well as have a sizable effect on the budget. Additionally, we have multiple layers of government (federal – three branches, state, county, township – not everywhere, municipality, some regulatory and taxing bodies that span these layers) that can sometimes add to the complexity. Furthermore, we are a relatively open society that incorporates many people and comes out with something “American.” We may not be one of the happiest countries in the world but a number of the countries at the top of the list are simply not as socially complex. Indeed, of the 13 countries ahead of the United States, only one is 1/10 the population size (Canada) and the rest don’t come close to that.

On the other hand, we have had an explosion of the Internet and social media that allows us to drill down to individual experience after individual experience. One way to think about social media is that it allows the experiences or opinions of individual actors to reach a wide audience. However, these individual experiences can blur the wider patterns at play. How can we compare anecdotes?

Perhaps the practical question in this: how do we operate between these two scales of a large-scale complex society versus the individual actor? It is not easy to do as either scale has drawbacks and benefits. At the least, it highlights that the “American Experiment” continues, perhaps now less based on our democratic and republican aspirations but more in terms of size and complexity.
