Book-Blogging – Scarcity, by Sendhil Mullainathan and Eldar Shafir

Scarcity coverAs I’m writing this, it’s the middle of the holiday season, which means that you’re probably a little dumber right now. A bit more scatterbrained. Likely reaching for that extra holiday cookie or for one more egg nog than you really need.

Upon reflection, you’d probably admit that this is at least partly because you have a lot on your mind; more last-minute gifts to wrap than time; and, after purchasing a plane ticket home, buying gifts, and (over-)indulging with friends, a much thinner wallet. You’re stressed out.

In the parlance of Sendhil Mullainathan and Eldar Shafir, you’re experiencing “scarcity” – you’re “bandwidth-taxed.” In their excellent read, Scarcity, the authors seamlessly weave real-world examples with clarifying experiments to show just how pernicious scarcity can be. I highly recommend picking up the book; it will change the way you look at your finances and your time. And hopefully it will change the way you think about how poorly-aligned our society’s understanding of individuals in poverty is; how a reimagining of anti-poverty policy could make everyone – but especially the poor – better off.

As Mullainathan and Shafir point out, scarcity isn’t all bad; as anyone who has written a last-minute paper or crammed for a test knows, a time constraint provides a useful “focus dividend” – it gets you to get stuff done[1].

But the costs of scarcity often outweigh its benefits. A packed schedule or a bank account near zero (or below) cause tunneling: focusing on the most pressing issue, often at the cost of the long term. You take out a payday loan to pay the late bill, even if it leads to usurious interest rates you’ll have an even harder time paying off next month; all your meetings start 10 minutes late, and none of them are all that productive; you choke on that first date you really wanted to go well.

It’s not just your free time or wallet that are depleted, though; it’s your bandwidth – a wonky way of describing “brainpower.” The correct understanding of bandwidth, Mullainathan and Shafir argue, is akin to a gas tank; you use it up over time, and when you’re working on a thoughtful task, you use it up faster than when you’re doing something mindless[2].

And when your bandwidth is taxed, you are dumber. Literally. In one of Mullainathan’s and Shafir’s studies, mall-goers –some well off, others poorer – were asked about a hypothetical decision to spend either $150 or $1,500 to fix some short-term car trouble, and then were given a test of Raven’s Progressive Matrices to judge fluid intelligence.[3] When given the $150 hypothetical, the rich and poor looked equally intelligent; when given the $1,500 hypothetical, the poor did significantly worse. As the authors note, this was significant both in the statistical sense and in the real-world sense:

 Our study revealed that simply raising monetary concerns for the poor erodes cognitive performance even more than being seriously sleep deprived… our effects correspond to between 13 and 14 IQ points. By most commonly used descriptive classifications of IQ, 13 points can move you from the category of “average” to one labeled “superior” intelligence.

Thinking about money issues temporarily made people less intelligent, by nearly an entire standard deviation. Mullainathan and Shafir found similar effects to executive control:

 The same farmer fared worse on fluid intelligence and executive control when he was poor (preharvest) than when he was rich (postharvest). Much like the subjects at the mall, the same person looked less intelligent and more impulsive when he was poor… The postharvest farmers got about 25 percent more items correct on Raven’s. Put in IQ terms, as in the earlier mall study, this would correspond to about 9 or 10 IQ points

This is why, the authors note, “scarcity creates its own trap.” Tunneling, and the juggling it forces, distorts decision-making:

Scarcity, and tunneling in particular, leads you to put off important but not urgent things—cleaning your office, getting a colonoscopy, writing a will—that are easy to neglect. Their costs are immediate, loom large, and are easy to defer, and their benefits fall outside the tunnel. So they await a time when all urgent things are done. You fail to make these small investments even when the future benefits can be substantial.

You make dumb long-term decisions because you only think about the most immediate and pressing things to do.

A proper understanding of, and reckoning with, these ideas leads to significant individual, social, and political changes.

For individuals, it may mean scheduling high-bandwidth tasks earlier in the day, or at least not scheduling all high-bandwidth tasks back-to-back; perhaps you should put mindless tasks – doing expenses, maybe, or clicking through low-priority emails – after something that requires your full attention.  And it means trying to turn all of the hard, repetitive decisions you have to make into one-time decisions; you can either have to say no to the chocolate bar every time you open the pantry, or just say no to it once at the grocery store. Same deal with habits: if you go on a run or to the gym on a consistent basis, choosing to go today will be, well, less of a choice.

As a society, these ideas should lead us away from viewing the poverty problem as a moral one – thinking that those in poverty are lazy or dumb or what have you – to a practical one. We know – or, more accurately, have a strong factual basis to believe – that a bandwidth-taxed individual is liable to make worse decisions, and that those in poverty are, by definition, bandwidth-taxed individuals. Properly considered, the research should lead to a greater level of empathy; we all know what it feels like to be bandwidth taxed – but most of us are fortunate enough to not feel like that all the time. Many aren’t, though.

If you view poverty through this lens, it’s easy to see how specific policy changes could help increase bandwidth and reduce scarcity. One stark example: payday loans[4]. Mullainathan and Shafir put it better than I can:

Many workers, as we saw in chapter 5, resort to payday loans. Yet it’s worth observing that a payday loan is often simply a loan against work that has already been done. The worker who takes a payday loan halfway through the pay cycle has already earned half her paycheck. The need for a loan is largely due to the fact that payment happens with a delay. Why should an employer have workers taking these loans, potentially falling into scarcity traps, taxing bandwidth, and resulting in lower productivity, especially when the employer can himself give pay advances at low cost? How valuable would it be for employers to improve productivity by offering the right financial products and creating bandwidth?

This is a pretty nonideological solution to a politically-fraught issue. There are costs to it, sure, but as the authors point out, it’s easy to see how they could be outweighed by productivity benefits.

Finally, policymakers and policy wonks need to learn how to craft programs that take the already-limited bandwidth of the poor into account:

We treat education as if it were the least invasive solution, an unadulterated good. But with limited bandwidth, this is just not true. While education is undoubtedly a good thing, we treat it as if it comes with no price tag for the poor. But in fact, bandwidth comes at a high cost: either the person will not focus, and our effort will have been in vain, or he will focus, but then there is a bandwidth tax to pay. When the person actually focuses on the training or the incentives, what is he not focusing on? Is that added class really worth what little quality time he managed to spend reading or with his children? There are hidden costs to taxing bandwidth.[5]

Scarcity is a problem we all face, in one form or another. And we face it together, too, as a society. Read this book and you’ll have a much better understanding of it.

The New Yorker’s Article on Fecal Transplants is Excellent

Fecal bacteria sample

On Fecal Microbiota Transplant (FMT), from a recent (excellent) New Yorker article by Emily Eakin:

“Nothing in health care works ninety per cent of the time,” Mark B. Smith, a microbiologist at M.I.T. who is a co-founder of OpenBiome, the stool bank, told me. Zain Kassam, a gastroenterologist who is OpenBiome’s chief medical officer, put it this way: “It’s the closest thing to a miracle I’ve seen in medicine.”

This piqued my interest; as Darius Tahir put it on Twitter,

Pretty much. I’ve written about fecal transplants and the microbiome a number of times in the past few years – see here, here, and here, for starters – and am glad to see some of the same research discussed in this article.

Book-Blogging: Making of the Atomic Bomb, by Richard Rhodes

The_Making_of_the_Atomic_BombRichard Rhodes’s Making of the Atomic Bomb is not for everyone.

For starters, it’s long – really, really long.  It’s also fantastically dense, serving as not only a history of the atomic bomb but also as a history of nuclear science, anti-Semitism in eastern Europe, and of World War II. And it can be a slog – at times, a hard read and a boring one to boot.

But it is the book to read if you want to learn about, well, the making of the atomic bomb and the Manhattan Project.

For that reason, writing a review of it is pretty much unnecessary: either you’re the type of person to read this book, or you’re not. If you are, I highly recommend it; if not, I don’t think you’ll like it.

Instead, after the jump I’ll list a few of the sections I highlighted while reading on the Kindle, mostly because I thought they were interesting or provided a unique perspective or thought.

Life-Saving Poop, Now in Pill Form

Ingesting fecal material is an excellent way to pick up some pretty nasty diseases, like cholera, typhoid fever (as I can personally attest), and a variety of other diarrhea-causing agents that, together, kill 800,000 children five years or younger each year. That’s 2,200 child deaths each day. It’s horrifying.

But paradoxically, ingesting cleaned, filtered, and safe fecal material can save lives, too.

Fecal bacteria sample


Researchers at Massachusetts General Hospital have created a pill containing filtered fecal material that successfully treated 19 of 20 patients with Clostridium difficile, according to a study in the Journal of the American Medical Association. 

It’s worth repeating: this is a poop pill. And it holds the potential to save tens of thousands of lives every year. 

Though the study was quite small, it shows that fecal transplants – an extremely effective but tedious and labor-intensive procedure – can be accomplished using two or three days’ worth of simple-to-ingest pills. If larger clinical trials are successful, this will be a game-changing therapy.

Clostridium difficile, or c. diff, is a disease that is resistant to many antibiotics and kills 14,000 Americans each year. I wrote a lot about it for a Project Millennialpost last year, but the short version is that c. diff is a hospital-acquired infection that becomes problematic once a patient’s microbiome is altered – often by antibiotics that kill many types of bacteria but spare c diff.  Unconstrained by the “good” bacteria (yes, I’m simplifying here), c. diff takes over the microbiome, causing diarrhea, fever, abdominal pain, and sometimes septicemia.

Treating a c. diff exacerbation with the traditional antibiotic regime can take weeks (often in an inpatient setting) and isn’t all that effective. Fecal transplants, by contrast, lead to quick recovery and are very effective; they don’t actually wipe out c. diff, but in restoring microbiome homeostasis they “tamp it down.” And the procedure works.

More trials need to be completed to ensure that a fecal transplant in pill form is as safe and effective as early results indicate.  If the trials are successful, this therapy will be an absolute medical game-changer.

In addition to being easier to carry out, a fecal transplant in pill form will mitigate the yuck factor (even if it doesn’t entirely get rid of it). The pill fecal transplant works in a matter of days and would likely be done on an outpatient basis, which would save thousands of dollars per patient and free up hospital beds for other patients.  And finally, it bears repeating that the therapy works.

Intriguingly, this modest success opens up the possibility of pill fecal transplants for other ends, like treating depressing and losing weight. Of course, much more research needs to be done in these areas, but the prospect of probiotic therapy for various illnesses would be significant.

Isn’t science cool? Scientists and doctors have managed to turn one of Death’s surest weapons against it, if only a little.

One-Fifth of Americans Worried About Getting Ebola Yesterday

Via Teju Cole's excellent satire at the New Yorker

Via Teju Cole’s excellent satire up at The New Yorker

Over one-fifth of Americans worried – in the past 24 hours - about getting ebola, according to a just-released Gallup poll. Six Americans are believed to have contracted ebola (a number which may or may not include the man who had ebola in Texas, Thomas Eric Duncan, who passed away this morning), and the risk is effectively non-existent, but almost one-in-seven Americans thinks that is is “very likely” or “somewhat likely” that they, or someone in their family, will get ebola.

The Gallup poll wisely compares perceptions of ebola now to the H1N1 outbreak in 2009 (also known as the swine flu):

Screen Shot 2014-10-08 at 11.51.19 AM

In other words, Americans are as concerned about ebola – a disease that poses no risk to them – as they were about the swine flu, a disease that may have infected over 10% of the American population and that killed 3,900 Americans. (This number, of course, is also only a fraction of the number of Americans that die each year from the “common” flu)

Any disease with a high case fatality rate is going to cause people to worry, and doubly so for a “new” or “foreign” one. But a cool, calm, and collected media apparatus would be able to tamp down fears of ebola if it was interested in doing so. That’s not good for gaining eyeball share, though, so organizations like CNN are sensationalizing the “outbreak” of ebola in America by comparing it to – and yes, this is true (see above) – ISIS, a terrorist group. This is disgusting and immoral in and of itself, but it also takes away mindshare from more pressing concerns, like getting a flu shot.

So no, America, despite what you hear on the radio or the television, ebola is not a threat to you. Do literally anything else but worry. Get a flu shot. Donate to MSF/Doctors Without Borders. Help – in whatever way you can – to reduce the ebola threat to Liberians and others in West Africa.
