Why and how does DARPA work?
Program Managers
At the end of the day the ARPA Model depends on badass program managers. Why is this the case? PMs need to think for themselves and go up and down the ladder of abstraction in an unstructured environment. On top of that they need to be effective communicators and coordinators because so much of their jobs is building networks. There’s a pattern that the abstract qualities that make “great talent” in different high-variance industries boils down to the ability to successfully make things happen under a lot of uncertainty. Given that pattern, the people who would make good DARPA PMs would also make good hedge fund analysts, first employees at startups, etc. so digging into people’s motivations for becoming a PM is important. More precise details about what makes a PM good prevent you from going after the exact same people as every other high-variance industry. When ‘talent’ isn’t code for ‘specialized training’ it means the role or industry has not been systematized. Therefore, despite all the talk here and elsewhere about ‘the ARPA Model’ we must keep in mind that we may be attributing more structure to the process than actually exists.
DARPA program managers pull control and risk away from both researchers and directors. PMs pull control away from directors by having only one official checkpoint before launching programs and pull control away from performers through their ability to move money around quickly. PMs design programs to be high-risk aggregations of lower-risk projects. Only 5–10 out of every 100 programs successfully produce transformative research, while only 10% of projects are terminated early. Shifting the risk from the performers to the program managers enables DARPA to tackle systemic problems where other models cannot.
That is one excerpt from a new and excellent essay by Benjamin Reinhardt, one of the best pieces of this year, via Patrick Collison.
Note also that DARPA underpays staff, does not hire individuals with a significant web presence, deliberately stays small, and makes it easy to reallocate funds on the fly. The program managers do not work there for any longer than four or five years, by design.
Can Philosophy Make People Generous?
Schwitzgebel and Rust famously found that professors of ethics are no more ethical than other professors. Peter Singer being perhaps a famous exception to the rule. In follow-up research Schwitzgebel and psychologist Fiery Cushman tried to find philosophical arguments to change people’s willingness to donate to charity. They were unable to find any. But perhaps they just weren’t good at coming up with effective philosophical arguments. Thus, they challenged moral philosophers and psychologists to a contest:
Can you write a philosophical argument that effectively convinces research participants to donate money to charity?
By a philosophical argument they meant an argument and not an appeal to pity or emotion. No pictures of people clubbing baby seals. The contest had 100 entrants which were winnowed down in a series of tests.
The test had people read the arguments and then decide how much of a promised payment they would they like to give to charity. An average of $2.58 was contributed to charity (of $10) in the control group (no argument). The best argument increased giving by 54% to $3.98. Not bad.
Here’s the argument which won:
Many people in poor countries suffer from a condition called trachoma. Trachoma is the major cause of preventable blindness in the world. Trachoma starts with bacteria that get in the eyes of children, especially children living in hot and dusty conditions where hygiene is poor. If not treated, a child with trachoma bacteria will begin to suffer from blurred vision and will gradually go blind, though this process may take many years. A very cheap treatment is available that cures the condition before blindness develops. As little as $25, donated to an effective agency, can prevent someone going blind later in life.
How much would you pay to prevent your own child becoming blind? Most of us would pay $25,000, $250,000, or even more, if we could afford it. The suffering of children in poor countries must matter more than one-thousandth as much as the suffering of our own child. That’s why it is good to support one of the effective agencies that are preventing blindness from trachoma, and need more donations to reach more people.
Now here’s the kicker. The winning argument was submitted by Peter Singer and Matthew Lindauer. Singer is clearly screwing with Schwitzgebel’s research!
You can read some of other effective arguments here. I don’t think it’s an accident that the winning argument was the shortest and also the least purely philosophical. I’m not saying Singer and Lindauer cheated, but compared to the other arguments the Singer-Lindauer argument is concrete and by making people think of their own children, likely to arouse emotion. That too is a lesson.
Why I like Nate Silver
There are standard reasons to like Nate Silver, which I do not wish to deny. But here is what I find striking: whenever he considers political or normative questions, he continues to use his full range of intellect and emotional maturity.
Many other commentators, once they run into normative or philosophical issues, or perhaps issues of political theory, or even political science, pull out arbitrary unsupported dogmatisms and partisan mood affiliation. Or perhaps they will use correct but shallow truisms they heard on the radio or read in a magazine or newspaper, without realizing that deeper levels of analysis are possible. Or they may use incorrect but shallow truisms from MSM. Either way, at some point the analysis simply falls apart, even if many of its constituent parts are well-informed or perhaps even expert.
It seems to me that Nate avoids this. I now consider this an increasingly important quality in commentators, especially if those commentators are active on social media.
And it is not that I agree with Nate all of the time on politics. I’m not saying this “because he ends up where I am.”
I will try to think about who else is very good in this regard, and how we might nourish this quality in ourselves.
We are living in a (very temporary) dining paradise
Of course current arrangements are terrible for restaurants, and pretty soon they will be bad for your dining too, as more restaurants close up for good. But right now we live in a window of opportunity.
The owner and/or best chef is in the restaurant at a higher rate than usual — where else can he or she go?
Menus have been slimmed down, so there are fewer dishes, which means fresher ingredients and less delegation of cooking tasks.
Most menus have new dishes, not otherwise available, often in the direction of comfort food, which is a comfort because it tastes good!
They are cooking just for you, yum.
Show up for lunch at 11 a.m. or for dinner at 4:30 p.m. Please only eat outside. Bring a mask as well. And please don’t linger at the table, so that others may follow in your footsteps.
Note which places have good outdoor dining arrangements, and which have nice park benches right nearby. (Don’t drive the food back home as it becomes soggy and non-optimal for human consumption.) You won’t end up with that many options to choose from.
Nonetheless I’ve had some very good and special meals as of late.

Why Americans Are Having an Emotional Reaction to Masks
That is the topic of my latest Bloomberg column, easier read through than excerpted, but here is one bit:
When no one can see our countenances, we may behave differently. One study found that children wearing Halloween masks were more likely to break the rules and take more candy. The anonymity conferred by masks may be making it easier for protestors to knock down so many statues.
And indeed, people have long used masks to achieve a kind of plausible deniability. At Carnival festivities around the world people wear masks, and this seems to encourage greater revelry, drunkenness, and lewd behavior, traits also associated with masked balls. The mask creates another persona. You can act a little more outrageously, knowing that your town or village, a few days later, will regard that as “a different you.”
If we look to popular culture, mask-wearing is again associated with a kind of transgression. Batman, Robin and the Lone Ranger wear masks, not just to keep their true identities a secret, but to enable their “ordinary selves” to step into these larger-than-life roles.
And:
The tension of current mask policy is that it reflects a desire for a more obedient, ordered society, for public health purposes above all, but at the same time it creates incentives and inclinations for non-conformity. That is true at least within the context of American culture, admittedly an outlier, both for its paranoia and for its infatuation with popular culture. As a society, our public mask-wearing is thus at war with its own emotional leanings, because it is packaging together a message based on both discipline and deviance.
What can we do to convince people that a mask-laden society, while it will feel weird and indeed be weird, can be made stable and beneficial through our own self-awareness?

Why the sudden uptick in cases?
From Nate Silver, I am smushing together his tweet storm:
Something to think about: re-openings have been occurring gradually since late April in different states/counties. If you had a metric averaging out how open different states are, it would likely show a fairly linear pattern. So why is there a nonlinear increase in cases now?
Obviously some of that gets to the nature of exponential growth. An R of 1.3 isn’t *that* different than an R of 1.1, but played out over a few weeks, it makes a lot of difference. Still, a more complete story probably includes premature re-openings coupled with other stuff.
What other stuff? Two things seem worth pointing out. First, there seems to be some correlation with greater spread in states where it’s hot and people are spending more time indoors with the AC on. That *is* a bit nonlinear; there’s much more demand for AC in June than May.
And second, the conversation around social distancing changed a lot in early June with the protests and Trump making plans to resume his rallies. And COVID was no longer the lead story. Not blaming anyone here. But the timing is pertinent if people felt like “lockdowns are over”.
Here is the link, including a good picture of how the demand for air conditioning rises.
Covid-19 India prize (post with fixed links)
It goes to the COVIN Working Group for their paper “Adaptive control of COVID: Local, gradual, and trigger-based exit from lockdown in India.”
As India ends its lockdown, the team, led by Anup Malani, has developed a strategy to inform state policy using what is called an adaptive control strategy. This adaptive control strategy has three parts. First, introduction of activity should be done gradually. States are still learning how people respond to policy and how COVID responds to behavior. Small changes will allow states to avoid big mistakes. Second, states should set and track epidemiological targets, such as reducing the reproductive rate below 1, and adjust social distancing every week or two to meet those targets. Third, states should adopt different policies in different districts or city wards depending on the local conditions.
This project provides a path that allows states to contain epidemics in local areas and open up more of the economy. Going forward the team plans to help address shocks such as recent flows of laborers out of cities and estimate how effective different social distancing policies are at reducing mobility and contact rates.
This project has 14 authors (Anup Malani, Satej Soman, Sam Asher, Clement Imbert, Vaidehi Tandel, Anish Agarwal, Abdullah Alomar, Arnab Sarker, Devavrat Shah, Dennis Shen, Jonathan Gruber, Stuti Sachdeva, David Kaiser, and Luis Bettencourt) across five institutions (University of Chicago Law School and Mansueto Institute, MIT Economics Department and Institute for Data Systems and Society, IDFC Institute, John Hopkins University SAIS, and University of Warwick Economics Department).

Lead headline and sub-header for The New York Times
“Overlooked No More: Valerie Solanas, Radical Feminist Who Shot Andy Warhol
She made daring arguments in “SCUM Manifesto,” her case for a world without men. But her legacy as a writer and thinker was overshadowed by one violent act.”
The piece itself notes she argued for the wholesale extermination of men, that other people treated it as satire, but she defended its seriousness. And of course she shot and tried to kill Warhol and came very close to succeeding. The nature of her other contributions is far from clear, although toward the end of her life she was eating from a dumpster bin in Phoenix.
Later, she moderated her views, and the NYT piece ends with this:
…the author, Breanne Fahs, writes about an exchange between Solanas and her friend Jeremiah Newton. Newton asked Solanas if her manifesto was to be taken literally. “I don’t want to kill all men,” she replied. But, using an expletive, she added: “I think males should be neutered or castrated so they can’t mess up any more women’s lives.”
Loyal MR readers will know that this is not a media-bashing site, nor is it a NYT-bashing site. I remain proud to have written there for ten years, and I remain a loyal subscriber, as I have been since I was ten years old.
But…come on. If you work for The Times, I hope you are in some way able to raise your voice against what can only be described as a grotesque embarrassment, not to mention a contradiction of Black [Men’s] Lives Matter. Maybe the headline will be gone or changed by the time you read this, but the saddest part is that this seems to be part of a pattern, not just a one-off mistake. I’ve known many people at the NYT, at various levels, and each and every one has seemed like a good (and talented) person to me. I can only conclude that something has gone very very badly wrong in the editorial control process.
Addendum: Timothy Noah comments.

What should I ask Nathan Nunn?
I will be doing a Conversation with him, he is an economist at Harvard, you could call much of his work economic history and economic development. Wikipedia notes:
A recurrent theme in Nunn’s research is the long-term impact of historical processes on economic development, often mediated through institutions, culture, knowledge and technology.
Key findings of his research include the following:
- Countries’ ability to enforce contracts is possibly a more important determinant of their comparative advantage than skilled labour and physical capital combined.
- A substantial part of Africa’s current underdevelopment appears to be caused by the long-term effects of the Atlantic and Arab slave trades.
- Current differences in trust levels within Africa are attributable to the impact of the Atlantic and Arab slave trades, which have caused the emergence of low-trust cultural norms, beliefs, and values in ethnic groups heavily affected by slavery (with Leonard Wantchekon).
- By impeding not only trade and technological diffusion but also the depredations of slave traders, the ruggedness of certain African regions’ terrain had a significant positive impact on these regions’ development (with Diego Puga).
- The introduction of the potato within the Columbian exchange may have been responsible for at least a quarter of the population and urbanisation growth observed in the Old World between 1700 and 1900 (with Nancy Qian).
- In line with Boserup’s hypothesis, the introduction and historical use of plough agriculture appears to have given men a comparative advantage and made gender norms less equal, with historical differences in the plough use of immigrants’ ancestral communities predicting their attitudes regarding gender equality (with Alberto Alesina and Paolo Giuliano).
- U.S. Food Aid is driven by U.S. objectives and can lead to increased conflict in recipient countries (with Nancy Qian).
So what should I ask him?
Ubundling the Police in NYC
In Why Are the Police in Charge of Road Safety? I argued for unbundling the police–i.e. taking some of the tasks traditionally assigned to police such as road safety and turning them over to unarmed agencies more suited to the task. A new report from Transportation Alternatives adds to the case. The report notes that the police in NYC aren’t even doing a good job on road safety.
For example, in 2017, there were 46,000 hit-and-run crashes in New York City. Yet police officers arrested just one percent of all hit-and-run drivers. In the past five years, hit-and-run crashes in New York City have increased by 26 percent. By comparison, DOT infrastructure projects designed to reduce these traffic crashes have proven effective and scalable.
Streetsblog (cited in the report and quoted here) also notes this remarkable fact:
Streetsblog recently reported that of the 440 tickets police issued to people for biking on the sidewalk in 2018 and 2019, 374 — or 86.4 percent — of those where race was listed went to Black and Hispanic New Yorkers. The wildly disproportionate stats followed another report showing that cops issued 99 percent of jaywalking tickets to Black and Hispanic people in the first quarter of this year.
Average is Over, installment #1437
Over the past few decades, we find that about 80% of the widening residual wage inequality to be within jobs.
Furthermore, performance-pay incidence is the single largest factor behind that, accounting for 42% of those changes. Of course this brings us back to the least popular explanation for growing income inequality, namely that we measure productivity better than before, and reward it accordingly.
That is all from a new NBER working paper by Rongsheng Tang, Yang Tang, and Ping Wang.
Economists modify a SIR model with a spatial and also behavioral dimension
We simulate a spatial behavioral model of the diffusion of an infection to understand the role of geographical characteristics: the number and distribution of outbreaks, population size, density, and agents’ movements. We show that several invariance properties of the SIR model with respect to these variables do not hold when agents are placed in a (two dimensional) geographical space. Indeed, local herd immunity plays a fundamental role in changing the dynamics of the infection. We also show that geographical factors affect how behavioral responses affect the epidemics. We derive relevant implications for the estimation of epidemiological models with panel data from several geographical units.
That is from a new paper by Alberto Bisin and Andrea Moro. Here is a good sentence from the accompanying and descriptive tweet storm:
In Spatial-SIR, local herd immunity slows contagion initially in the less dense city, but faster global herd immunity slows it in the denser city later
I think this means West Virginia is in for some hard times fairly soon.
