Mathbabe’s Guide to Overtravel

Friends, I travel a lot. Too much, if you ask me, or my youngest son, or my husband. It’s all for work, because nowadays I make money giving talks, and also I give book tours in foreign countries where publishers are kind enough to buy, translate, and publish my book, or sometimes I even travel for business related reasons for my company ORCAA.

Long story short, I travel way. too. fucking. much.

But I think I might have just figured something out about traveling, and I wanted to share it with all of you. In fact it’s not one thing, it’s a whole bunch of little things that might just add up to one medium sized thing. It’s also possible that I simply feel that way because of next dimension jetlag, but whatever, I’m in the mood to share.

And in case you’re wondering if I travel enough to feel like an expert, I’m traveling right now, and I started out in Lexington, Virginia, and then Barcelona, and then Madrid, and most recently Seoul South Korea, and now I’m in Paris, which to be honest is the best stop of all in terms of environment.

So yeah, I kind of have some idea or ideas about overtravel, and I’ll list them in random order of things that come to mind:

  1. People who don’t travel too much, I have some very very good advice: please don’t hate people who travel business class. They’re only doing that because they’d rather be home with their family, and yet they’re on yet another fucking airplane, and they tried to get out of it by explaining that their kids and spouses have threatened to never talk to them again and that they cannot face another trip in coach squeezed like a lemon in between smelly farty people including themselves and so whoever pays them offered to bump them up to biz class and they reluctantly – reluctantly! – said ok because they need the money.
  2. Said another way, business class is only disgusting and righteous-anger-generating for people when they compare it directly to coach class. In other words, they are assuming that the person had to fly, and they got to fly business class, whereas everyone else had to fly and they ended up flying coach, and that sucks. And while I’ll agree that sucks, we should instead be comparing all of this to *not flying at all*, in which you’ll have to admit flying business class is actually way suckier than being at home, or literally anywhere else besides flying coach.
  3. Same goes with lounges in airports. Nice compared to the smelly fucking mall atmosphere of the rest of the airport, way worse than being home with wifi and your actual favorite people in your actual favorite time zone. Also the food is generally speaking terrible, and they never, ever offer you peanut butter crackers that you can eat later in your hotel that maddeningly doesn’t have a minibar even though everyone knows minibars are everywhere extremely profitable because of jetlagged people running out of peanut butter crackers in the middle of the night.
  4. To conclude, lounges in airports have terrible food and offer you absolutely nothing that you can carry with you by design, not even oyster crackers in those little bags. They might – if you’re lucky – have oyster crackers, but it will be in a huge bowl and you’ll have one of those tiny plastic tongs to retrieve them, again literally designed so you can’t stand doing it for more than five minutes, resulting in about 4 oyster crackers.
  5. The one thing you can count on, both in lounges and while flying business class, is a shit ton of free drinks. If I wanted to hide an alcoholism problem, then business traveling would be The. Way. To. Do. It.
  6. As it is I have a “I’ll try not to drink more than I should” attitude and I still always end up drinking about a drink more than I should, resulting in mild regret mixed with mild hangover mixed with jetlag mixed with righteous anger about having to be, once again, not near my family. So once again you end up with righteous anger whether you’re traveling business class or you’re traveling coach.
  7. That leads to the important traveling question, what should one do with righteous travel anger? But first let’s talk about an even more urgent question, namely what to pack.
  8. Always, always pack lots of peanut butter crackers. And by that I really mean pack something that you can consistently eat in the middle of the night when you’re in a weird time zone relative to your internal brain time zone, and which won’t gross you out, but will also not tempt you whatsoever when you’re relatively satisfied, including when you’re in an airport lounge, which is a low fucking bar and hard to get much lower without being truly disgusting.
  9. So it’s kind of tricky to find that VERY middle of the road kind of food, especially that comes in super packs and is cheap and portable, but for me peanut butter crackers are perfect. I have a special pocket in each of my carry-on bags specifically devoted to peanut butter crackers.
  10. Before I get to all the different carry-on bags I own, and why, I’d like to list all of the other things you absolutely must pack on every trip. Here goes:
    1. Lots of advil. I bring tons of these little travel size packs of advil, two per package. Good for hangovers, good for aches and pains of uncomfortable travel, and good to fall asleep when combined with alcohol. And before you judge me, know that I’m the only person that travels a lot who doesn’t take actual sleeping pills. Nothing else can explain how, on trips over oceans, everyone around me is asleep the instant the meal is over, even if it’s 3pm local time. Not that sleeping pills are bad, because I don’t know if they are, but I’m afraid of them becoming addictive, so I avoid them, and instead I drink one too many drinks and take advil and that works out pretty ok, as in just about terrible on average. One or two packs per day of travel.
    2. Lots of dry coffee. I bring these, at least two per day of travel, because the above plan for sleeping while flying is actually terrible and I’m always tired, and the hotel’s dry coffee is always like brown uncaffeinated water compared to actual coffee. So I actually use both per cup.
    3. Did I mention peanut butter crackers? Can’t travel without them. One per day of travel, maybe two.
    4. Travel toothbrush (the kind that folds) and travel size toothpaste. Never bring a large bathroom bag, it wastes space. bring a bathroom bag (or what I use is technically a cosmetics case) that is too small for a real toothbrush, and limit yourself to filling that bag with mini sized everything, then top it off with as many advil and dry coffee packs as you can squeeze in there. You might need to bring deodorant separately. Also you’ll get more free tiny toothpastes if you travel business class, so don’t bother to bring more than one.
    5. I separately bring my travel-size pill box, because I need to take multivitamins and thyroid meds daily. I actually have three different travel size pill boxes depending on how long my trip is, and I always bring the smallest one that can fit all my pills.
    6. A knitting project that’s not too large. I mean, if you don’t knit, replace this with some hobby thing you can do when you’re drunk in an airport lounge and there’s no baseball on TV and the wifi sucks and you’re fighting off existential angst (more on this below).
    7. Laptop, chargers, phone, and wallet, passport and adapters if you’re traveling to another country.
    8. Paper printouts of basic details of where you’re going in case there’s no wifi or phone signal when you land. To tell you the truth there’s always wifi and phone signal, so I think this is just me being old and you don’t actually need paper anything anymore.
    9. Clothes, but I’ll delay saying more about this because…
  11. OK and here’s where I’ll talk about all the things you should NOT pack:
    1. Don’t pack more clothes than you need. Just one outfit per day of travel, no more, and one blazer or sweater that goes with all of the outfits, or at most two if the trip is long, and one coat. Don’t bring an umbrella, ever. Easiest thing is to choose outfits that all go together, or better yet multiple versions of the same exact outfit. This is easy for me because everything I own is black.
    2. Some unsmelly people can even get away with less than one outfit per day. Not me, I’m super smelly.
    3. Most importantly, don’t bring more clothes than can fit in an international sized carry-on. If your trip is longer than a few days you’ll end up doing laundry or paying outrageous prices for the hotel to. It’s worth it.
    4. Don’t pack books. Bring your laptop with stuff to read, or better yet audiobooks on your phone. Business class seats have USB chargers so you don’t need to worry about losing juice on your phone, and if you’re in coach then bring a portable battery. As long as you’re not lighting up the screen, your phone can run many hours with an audiobook and not use up too much battery.
  12. If my trip is short, I might be able to pack everything into my luggage carry-on, but I’ll still bring a very small “personal” carry-on, kind of like an actual purse but I hate purses so actually a drawstring bag, to hold my ticket, phone, wallet, headphones, and obviously peanut butter crackers.
  13. If my trip is long, I’ll take a larger personal carry-on which will include my knitting project and possibly my bathroom bag and pills.
  14. If my trip is very short, sometimes I’ll fit everything into one large backpack.
  15. You’ll never regret having less to carry.
  16. Unless you forget peanut butter crackers.
  17. OK now that we know what to pack, let’s talk about the real issues, which are existential angst and righteous anger, the twin menaces of overtravel.
  18. Because, and here’s the thing, traveling means having multiple shallow interactions with multiple people on a daily basis. It’s enough to make you think there’s no such thing as love, or meaningful connection, or even meaningful conversation, especially because it’s always in relief of a backdrop of “the news,” which is typically the only thing available on TV in English, which is always bad and quite possibly horrifying.
  19. The short answer to this problem is to remain “open and connected,” which is a squishy concept but basically means, assume that the person you’re about to meet is interesting, deep, thoughtful, and is about to expose something unexpectedly important and meaningful to you. But also, don’t hold it against them at all if they don’t. They just weren’t at the right place for that, but you are.
  20. Remaining open and connected is hard work, but it’s important, and is the single best piece of advice I can give to people who overtravel.
  21. It also likely comes across most of the time as simply being nice. That’s ok. Being nice is a good thing.
  22. But also, being nice is an invitation to conversation as well as a signal that you won’t judge, which is even more important.
  23. Of course, being open and connected is more than being nice, and it’s easy to start a conversation with the intention of being nice but not of being open and connected. That’s kind of lame.
  24. You gotta push yourself to actually be open and connected, which is to say finding out, without prying, something about the person, or exposing something about yourself that you didn’t even know about (ew, not in a gross way), or at least being willing for the conversation to go in unexpected ways and to find a universal truth or commonality with this person even though they’re coming from a totally unique place.
  25. Righteous anger is an impediment to remaining open and connected.
  26. That means righteous anger is something you need to acknowledge and deal with immediately, even if it’s embarrassing. It’s especially embarrassing to feel righteous anger when you’re flying business class to an amazing city to give a talk about your book that a bunch of people read and loved, because for god’s sake it’s a fucking dream come true.
  27. But then again there it is, sometimes you’re just feeling petty and small and wishing you could be home with your goddamned family and not eating any more goddamned peanut butter crackers, and that resentment makes you not only sad and shitty and embarrassed but also incapable of remaining open and connected whatsoever.
  28. To get over the embarrassing righteous anger, I suggest meditating on gratitude while knitting.
  29. Remaining open and connected is hard, but it’s totally worth it, and you’ll make friends you never thought you’d make.
  30. Also, sometimes you hit an open and connected wall, because at some point you hit the existential angst wall, which is to say the moment when you realize that interactions between humans, even when they’re meaningful and kind, cannot heal one’s wounds, and that it’s only a person’s own sense of worthiness that can ever do that. And maintaining a sense of worthiness is even harder than maintaining a sense of openness and connection.
  31. I’m working on that last thing. The great thing about traveling is that it gives me lots of time to work on that last thing, but friends, it’s really hard, maybe the hardest thing of all.
  32. Which is really all you can ask about something like travel, that it lets you work on the hardest thing of all, because honestly who has time in their normal lives to work on the hard stuff?

Guest post: China’s Social Credit System

This is a guest post by Jianyin Roachell, Social Innovation, SAS-certified Data Intelligence Developer, US-China-EU relations.

My name is Jianyin Roachell, Chinese American and I have been researching how digital innovation and big data can impact socio-economics and political economy in China. In this guest blog, I hope to enlighten you with instances of how big data and AI may change the role of firms and governments, what is China’s National Social Credit System, and perhaps collaborations between business and governments to increase upward social mobility using big data. Allow me to make it clear, I am not promoting or degrading any Chinese social policies in this blog.


To understand why I do what I do, allow me to introduce my background. I am a Chinese-born-American and grew up in Memphis, TN, the city where Martin Luther King Jr’s died and known for our civil rights movements. Memphis is notorious for the dysfunctional education system and gun-violence (two of my friends were killed). With lingering residual discriminations from Jim-Crow South and police brutality anxiety, the city of Memphis where I grew up suffered social distrust between the at-risk communities and the rest of the middle class. I really witness some of the stark contrast between upper and lower class while growing up in social the social circles. After reading Cathy’s book, “Weapons of Math Destruction”, I was inspired to pursue my passion in social innovation and digital social justice. I am currently a Master’s student studying Economics and Computer science. My background is in statistics and data analytics. My interests lie in the center of Entrepreneurship-Innovation, Socially Responsible Algorithmic Design, and data ethics.

I always wanted to travel the world, Why not go to China… I asked myself. That’s where lots of things are happening, and after all, I am Chinese. My China experience has led me through some amazing self-discoveries and also discover a few glimpses of what the future may hold within socio-economics and policy.

China’s AI

I predict that China’s AI systems and technology will surpass that of the West for two reason. Namely, the sheer size of China’s population and very ambiguous data privacy laws. Companies are building machine learning models that train on 1.3 Billion people’s personal data points. I predict that China’s AI technologies will be more accurate and more scalable than that of the West in the near future. The data privacy laws are not very established, giving companies and local governments opportunities to exploit them for unethical profit-seeking and political agendas.

The penetration of big data and algorithms.

In China, where the government plays the role of ‘parent’ culturally, it is comparable to our own upbringing: “do you not eat your vegetables properly? Then no television tonight!”

With the arrival of AI and big data, in the consumer market, firms are beginning to play the role of Mother, figuratively, while the Government is playing the role of the Father. Mothers on average give you treats to incentivize you to do something good, while dads are there to give your butt a good beating when you misbehave.

In China, consumers are sucking on the tit of business discounts and freemium products, while the government is monitoring bad behavior through a very data-driven censorship system. By 2020, China will roll out a national social credit system to quantify every citizen’s social worth in society through what they buy and how they behave. This is the socialism engineering at its finest.

Role of Firms in relations to Big data

In the US, tech companies like Google and Facebook own the user data; whereas, in China not only do the Tech Giants (Baidu Alibaba Tencent or BAT) but also The Government can access the consumer data. China is currently in transition from a manufacturing manual labor-based economy into a skilled-labor and high-tech consumption economy.

What China needs now is to really develop its credit system and open up the credit market. Inevitably, the BAT’s shopping-spree for start-ups and mergers have led to the construction China’s first social credit system. How? When BAT companies purchase smaller companies, they also buy their data access. With the huge amount of data gathered from multiple child-companies, BAT giants are able to use big-data to gamify China’s consumer market and hype up demands for products, goods, and services. This is the narrative that will define the 21st century as China finds the next chapter for sustainable growth. The construction of a national social credit system will engineer new social behavior and public ethics in an entirely different way we understand in the West.

There are different attitudes that East and West perceive AI tech. The East tend to apply AI for the common good and thinks AI can be a virtual partner or a quasi-member in society (example: Japan Society for AI book of ethics present that AI should be a quasi-member of society); whereas in the West, AI is perceived as a tool to generate more value, save more money, and increase further productivity. Because of this difference in outlook, the future of AI development may also shape how we live our daily lives in each of the West-East spheres.

Social Credit Score: Big Brother?

To understand why China is doing this, first we must understand China’s culture. With Confucianism as the nucleus of familial code of conduct, dating back thousands years of Chinese Culture, there lies the value of “the natural order between Authority and the People.” This means that it has always been in China’s DNA to trust and obey the authorities even in the ancient chinese imperial times. The western media describes:
“The worst-case scenario is a form of high-tech Stalinism for our brave new world.” But actually there are two different systems that makes up the National Social Credit Score:

1) the commercial credit system (similar to US’s FICO and German Schuffa) and

2) social management system (big-brother-like mechanism).

The commercial credit system: is suppose to measure your financial credit and how likely you’re likely to pay back your loans. Scores range from [350-950]. Loans, credit markets, and mortgage markets will be heavily dependent on this score. This score will reflect all the accumulation of all your digital purchases and how trustworthy are you. China is filled with business con-men, and this system can actually hold those bad business accountable and financially punish them before they produce bad products into the market.

Social management system: put miscreants and offenders on a blacklist, where the government will extract data from the judicial and law enforcement data-base and pass the data to Ant Financial to decrease the offenders’ commercial credit scores. The lower the credit score, the less benefits you will get from commercial digital vendors.

Socio-economic Implications and Going Forward

Dating: Because financial capacity is an important aspect when looking for a partner, Sesame Credit is also integrated into various dating sites, so that users can see the scores of their potential partner. This is not a new idea. Matchmakers in ancient times have matched couples heavily on their socioeconomic background. However, in our modern society, over time this may further solidify the classes and may even amplify the effects, where the lower-class will stay poor, and upper class will stay wealthy. This will more likely exacerbate wealth inequality as their children progress forward into their lives; thus upward social mobility will be limited. The current literature has been focusing on the “big brother” side of the Chinese Social credit system; instead the argument should be asking how big data can offer a different solution to this problem. There are so many opportunities for firms and government to work together to increase the value of the people, bring them out of poverty, and give policyholders the intelligence to redistribute wealth to the groups are most at-risk of unequal opportunity. I call this the era of “Digital Social Mobility.”

Technology can help us even up the playing field and bring equal opportunities. Please see my research poster here to learn more about this topic. I believe truly that if we put out resources together we can sparking a new movement that can redefine and reimagine the human experience in this 21st century.

New Politics and Philosophy Podcast: The Badlands

September 22, 2018 3 comments

This is a guest post by Toby Napoletano, a philosophy PhD who is working on a politics and philosophy podcast that is the subject of this post.




I’ve taught quite a few introductory ethics courses to undergraduates over the past five years or so. During that time, I’ve had the good fortune of having lots of really good, thoughtful students who were fairly politically engaged—enough to at least be aware of some of the major moral and political issues that dominate political discussion.

But I’ve noticed a bit of a trend with these students that I think should be worrying to those who identify themselves as being broadly on the political left. Namely, for lots of the students who identify themselves as being generally “liberal”, the most salient political commentators for them tend to be quasi-intellectual right-wing libertarian types like Ben Shapiro. While they might disagree with him, they respect him as someone who uses “facts” and “logic”—i.e. who at least gives the appearance of trying to reason with them.

I don’t think this is an accident. What is distinctive about libertarians—even those like Ben Shapiro—is that they keep their deep philosophical commitments right out in the open, and they don’t hesitate to appeal to them. Why are minimum wage laws unjustified, according to the libertarian? Well, at bottom, because doing so would prevent people from entering into certain voluntary economic agreements with each other—i.e. ones where labor is exchanged for less than minimum wage. Such laws would infringe on the liberty of individuals to enter into those agreements, and government, as a rule, cannot do this. Government is meant to protect this sort of liberty, in addition to individuals’ basic rights to property and physical security.

There are plenty of ways to resist this argument, but doing so requires engaging with the underlying philosophical commitments. For instance, under what conditions is labor exchanged for a wage voluntarily in the relevant sense? Is it voluntary in the sense that counts if the alternatives are to work for a pittance or to starve, or to forego medical treatment, etc.? And further, what’s special about rights to physical security, property, and freedom of contract? Might there be other basic rights which governments have obligations to protect like a right to subsistence or essential medical care?

But my thoughtful students (and presumably plenty of thoughtful non-students) don’t see anybody on the left raising these questions or engaging with the issues on this level. Consequently, they don’t have good answers to the deeper philosophical challenges that might be raised against leftist positions, and some of them will conclude that there just aren’t good underlying justifications for those positions and abandon them altogether.

Consider the case of economic inequality. For folks on the left, the bulk of the conversation has been spent on the statistics illustrating the state of inequality in the U.S. And this is for good reason—the numbers are staggering. They then conclude that there is something basically immoral and unjust about this inequality. But then the response from those who are less concerned with inequality is just that the great inequalities in wealth and income simply reflect differences in merit, and so they do not reflect any basic injustice. The progressive left, they charge, is obsessed with the idea of everyone being economically equal. What justice requires (as they often put it) is not equality of outcome, but equality of opportunity, citing the ideals espoused in the American Dream.




Interesting—an argument invoking the ideas of merit, opportunity, and justice. Of course, it happens to be a strawman—I don’t know of anyone who could charitably be interpreted as advocating for a completely equal distribution of wealth. Nevertheless, the argument suggests that we need to go a bit deeper, and wrestle with potentially difficult, philosophical questions. For instance: What’s the relation between opportunity and justice? What is the relation between economic inequality and opportunity? What is merit and how does it relate to economic outcome? Would meritocracy even be a good thing?

One of the reasons progressives care so much about economic inequality is that they agree that justice requires some semblance of equality of opportunity, but recognize the myriad ways in which extreme economic inequality undermines equal access to opportunity—both economic and educational. These disparities in access to opportunity then further entrench the economic inequalities (and expose the idea that the distribution of wealth in the U.S. is merit-based as being clearly false).

Putting the issue of opportunity aside, there is a basic human rights issue that the extreme inequality in the U.S. makes pressing. Namely, it’s not just that there are large gaps between the rich and poor, but that the poor are actually deeply impoverished, struggling and often unable to lead a decent life. The presence of extraordinary wealth amid this deprivation suggests a failure to protect basic rights, and a failure which could be easily prevented. Even if those who end up poor, by and large, did have the same opportunities as the wealthy (which they clearly do not), it still wouldn’t follow that the situation is a justifiable one.

Arguments like these are the kind that need to be made and understood with some clarity if one is going to be justified in believing that economic inequality (to take just one example)  is, in fact, a serious problem. These arguments are what fill in the gap between the statistics demonstrating the inequality and the moral conclusion that the inequality is unjust.

This is all a long-winded way of saying that there is real value to engaging with the philosophical dimensions of political issues. Not only is such engagement necessary to really understand some of the underlying disagreements, but there is strategic value to doing so as well. Commentators on the left do themselves and their positions a disservice by not engaging with the issues at greater depth, because there are plenty of good arguments in favor of those positions.

The aim of The Badlands Politics and Philosophy Podcast is to try to help fill this gap. On the podcast, a group of fellow philosophers (Michael Hughes, Hanna Gunn, Jared Henderson) and myself explore the philosophical dimensions of contemporary political issues. Along the way, we give a philosophical sketch and defense of a broadly “progressive” political outlook. If nothing else, we hope to help raise the standard of political discourse in some small way.

The podcast is aimed at a general audience and so isn’t meant to require any specialization in philosophy to enjoy. Early topics include money in politics, economic inequality and the myth of the American Dream, inequality of opportunity, the idea of American meritocracy, and issues concerning political discourse and political coverage in the media. In the near future, we plan to do episodes on the meaning of “capitalism”, the relationship between Milton Friedman and progressivism, the ethical implications of AI, the ethics of immigration, and lots more.

New episodes are released every Friday, and written pieces are posted regularly on

We are on Twitter at @TheBadlandsPod.
