Quick update on my earlier post about Oxbridge Admissions. After more than a decade of running on its initial design from 2006, I'm happy to share that the new Oxbridge Admissions site is now available in beta. The app is still fairly rough around the edges, but we wanted to get things up and running in time for the 2020 entry application cycle that's just kicking off. We will be fixing some of the more pressing issues over the coming weeks, and there will be a larger UI/UX revision after that too.

As part of the transition, we've also moved from the original oxbridge-admissions.info domain to the nicer oxbridgeadmissions.com. And finally, we've added a new blog, where we will be posting compilations of the most relevant advice from individual profiles, organized both by subjects and colleges.

Good luck to everyone applying this year!

A year ago, I wrote a brief post on British and American pharmacies as allegories for our food-sickcare industrial complexSince then, the post sparked a number of interesting conversations with friends. A recurring theme throughout those conversations was a question many of us thought of, but which none of us had a good answer for. 

Why is that in the US and in the UK, purveyors of foods seem to engineer their foods for maximum addictiveness, at the expense of their customer's health, much more so than seems to be the case in continental Europe? 

A few of the most ubiquitous examples would be sweets, portion sizes, and "super-processed" foods including sugar.

1) Sweets. In most Swiss, French, or Czech grocery stores, you can find a salty chocolate bar, a caramel chocolate bar, and an almond chocolate bar. But you cannot find the most addictive version of said product, at least for some people - say a double caramel salty almond fudge chocolate bar. In most American or British supermarkets, you'll find something like that though. Same thing goes for ice cream.

2) Portion sizes. Although there has been some size creep, the X-Large drink size available in most continental cinemas (if they even have an X-Large!) is still equivalent to somewhere between an American Medium or Large, i.e. 1.5 sizes off (and probably half the volume).

3) Super-processed foods & sugar. Europe gets its fair share of processed foods, but it seems to do generally better on what I'd call "super-processed foods": corn syrup, chips made from potatoes or grains processed to a degree where you can't tell which of the two they started with, flavors that don't even attempt to replicate some food group that exists in nature, etc. I'd include sugar in this bracket - continental countries love their pastries, but they generally don't jam sugar into other foods groups with the same ferocity that food producers seem to do in the UK and in the US.

Why could this be happening? There are a few tempting explanations that come up, though I'm not sure any one of them, or even all of these combined, explain this properly.

1) Regulation - European food regulators are just stricter, and they ban or heavily regulate more of the bad stuff.

2) Cultural norms - more of the people who run European food companies have some kind of cultural bias against producing this kind of stuff, and so it doesn't get as extreme. This would not explain why American food brands don't just supply this part of the European market instead though.

3) Timing - Europe is just behind the US in adopting the "fruits" of late-stage capitalism. Give it 10 years, and Europeans will have caught up to the delight of buying a gallon-sized containers of salty caramel fudge almond crunch ice cream.

4) Local tastes - maybe it's hard to develop a taste for some of the more extreme flavors later in life, so this stuff wouldn't sell in Europe. Counter-example: many Europeans who come to the US readily admit that they got used to and started liking some of these flavors within a year or two.

5) Shareholder pressure - although this has been changing, management of European companies still seems to be subject to less pressure from investors to deliver returns at any cost. If your investors are forcing you to grow earnings in a mature market for snacks, generally speaking, the answer will be "Let's add more sugar."

I'm sure that some of these factors go part way towards an explanation, but I feel like there is more going on here. If you're reading this and have other factors to add to the list, I'd be curious to hear them.

In the summer of 2006, just a month or so before going up to Cambridge for my freshman year, I took a couple of weeks out of my summer break to build Oxbridge Admissions. The site was inspired by an earlier, similar site that had existed for a few years, but had become defunct. 

The goal was to help level the playing field for everyone applying to Oxford and Cambridge. For many years, elite boarding schools in the UK and abroad had collected information from their students who applied to the two universities. After coming back from interviews, each student would write a report about the experience. This meant that when a student at those schools decided to apply, they had access to hundreds of written profiles about what to expect and how to prepare. For a young person applying to the venerable universities shrouded in mystery, this was a significant advantage. Unfortunately, those applying from less selective schools, or from schools abroad who rarely if ever sent anyone to Oxbridge, did not have the same advantage. This seemed grossly unfair.

Long story cut short, sitting on the terrace of my parents' house in the Czech Republic, I hastily coded a basic version of the site, and recruited a few friends to help with moderating the submitted profiles. We also put in the work to find the profiles from the earlier site on archive.org and manually copied & pasted many of them into the new site. By August 2006, the primitive site was up and running.

Initially, we had some ambitions to add to and improve the site over time, but those never materialized. During the almost 13 years since the site launched, I probably spent a total of less than a day on updating the code or even maintaining the box it runs on. During that period, it probably took 2-3 hours per year to review and approve newly submitted profiles.

Despite this minuscule effort, the site still ranks #2 to #5 on Google for "Oxbridge Admissions". Over those 13 years, tens of thousands of people have read the profiles. [2] Given that every year, less than 20,000 people apply to either university, that's an amazing number of students who benefited from a more equal footing when applying.

To me, this is just yet another example of the power of product-market fit, even for non-profits: if you get product-market fit right, you can mess up (or not do at all) a lot of other things and still create a lot of value for your users.

[1] Of course, the site looks accordingly — like something that was thrown together quickly in 2006 and not touched since then. Given its ongoing popularity, the site does deserve an update though — I'm working on one that could last for the next 13 years.

[ 2] Dozens end up coming back afterwards to submit a profile of their own.

I've long been curious to learn whether the Swiss healthcare system could work in America, but I've never actually put in the work to understand this. I know that Obamacare was partially inspired by the Swiss model, but I also know it left out some of the key pillars.

So far, I have not done the work to understand how many other things would need to change for the Swiss model to work here — both legislative and cultural. Can the Swiss model co-exist with employer-provided healthcare? High levels of non-compliance? Opaque healthcare markets and lack of transparency in pricing? State vs federal regulation?

I'm going to read more about this topic over the coming weeks. If you have recommendations, I'd love to hear about them — please drop me an email or DM me.

In the meantime, this article by the Foundation for Economic Education seems like an interesting start: Why the Swiss Health Care Model Will Never Work in America.

Counter-intuitively, this is an optimistic post.

A month ago, the U.N. Intergovernmental Panel on Climate Change (IPCC) published a new report. Amongst a long list of bad news, the report states that our CO2 emissions "would have to be on an extremely steep downward path by 2030 to either hold the world entirely below 1.5 degrees Celsius, or allow only a brief “overshoot” in temperatures." This is more pessimistic news that many had expected.

Unfortunately, it's not entirely surprising. Three years ago, in Opti-pessi-mistic tweetstorm on climate change, I wrote "It’s a public secret that things are way worse than we think. But scientists can’t say so else they would lose all credibility. Catch 22."

To expand on this point — for a long time, if you were a climate scientist, you needed to walk a fine line. On the one hand, sound alarmist enough to make people care and take this seriously. On the other hand, you couldn't say things that were too pessimistic — for the fear of creating a helpless reaction of "Well, if it's so bad, we can't do anything anyway, so why bother." 

I fear that this dynamic caused a significant under-statement of how bad the situation is. I suspect that we're finally getting to the stage when the science cannot be played down any further, and we may see all the bad news start coming out at once. The IPCC report was probably just the first drop.

I don't think that's necessarily a bad thing though. Over the last twenty years, we've proven that if predictions are just moderately bad or we have "a lot of time", we won't do enough to reduce emissions. Most countries, organizations, and individuals need to face the true magnitude of the crisis to change their behavior. So it's good to see reality come out into the open.

This will be an incredibly difficult fight, but there are signs that make me optimistic — both geo-engineering in general, and CO2 capture in particular.

Much has been written [1] about the American healthcare system and why it fails us, especially for those not in the top 10% [2]. I'm by no means an expert, but over the years, I've often come back to a story I heard from someone at a dinner party a few years ago. We'll call him Paul.

Paul's girlfriend, Tina, needed to get a standard panel of blood tests. She found a clinic, went in, and got her tests done. Two weeks later, she received her results, together with a bill for $5,000.

As it turns out, Tina made a mistake and went to an out-of-network clinic. Panicked, she called her insurance company. Unsurprisingly, they weren't very helpful. Despite her pleading, she was told their maximum was $1,500, that her reimbursement check was in the mail, and that's all they could do.

As a last-ditch effort, Tina called the receptionist at the clinic that did her bloodwork. She explained her situation, not expecting much. Without taking a breath, or even passing Tina to accounting, the receptionist immediately offered something unexpected. "If you can pay by credit card right now, we can settle everything for $500."

Shocked, but not willing to risk her good fortune, Tina took the offer and paid over the phone. A few days later, the $1,500 reimbursement check from her insurance provider arrived. Tina cashed the check, and went shopping.

I don't approve of Tina's ethics, but I thought the story explained much about why our healthcare is so expensive. We've created a system where every party is incentivized to use opaqueness and lack of transparency against everyone else.

Over the last few years, I've often wondered about the right heuristic for deciding which hobbies to pursue.

"Enjoyment" or "passion" get thrown around, but I've found it's not that simple. Some hobbies create a lot of joy/pleasure upfront, but that enjoyment doesn't necessarily increase with time (e.g. fine dining [1]). Others aren't necessarily fun when you start learning them, but you can get better for years and years, and the enjoyment keeps increasing, too (e.g. tennis).

Besides, there are only 24 hours in a day.

Two years ago, I came up with a somewhat unusual metric, but I've found myself coming back to it ever since. 

The heuristic is pretty simple: "When doing thing __X___, how easily, and how long for, do I forget that I have a smartphone in my pocket/backpack/car?"

(Winner so far: fly fishing.)

[1] I realize many foodies will disagree. I believe they enjoy each meal more as their knowledge increases and palate gets more educated. It just doesn't work that way for me.

Walk into the average pharmacy, especially in the US/UK.

Half the aisles contain addictive stuff that makes you sick. The other half carry addictive stuff that mitigates just enough of the symptoms to keep you consuming more of the former.

In many cases, the same company produces goods of both types.

This is a bit exaggerated.

Unfortunately, it's also mostly true.

Two and a half years ago, I wrote down my best guess for what will happen regarding climate change:

  1. We should try to minimize CO2 emissions.
  2. But, given the incentive structure, we'll most likely fail to eliminate enough, quickly enough.
  3. Since cost of geo-engineering the atmosphere to let through less sunshine is low, at least one actor (private or government entity) will most likely attempt to cool down the planet, at least temporarily ("put sunglasses on the planet").

A month ago, some new data and claims came out on CO2 capture technologies, suggesting that the cost of removing a ton of CO2 could be closer to $100-200, rather than the $600 we had long thought was the minimum cost we could achieve.

$100-$200/ton is still more expensive than what it costs us to reduce our emissions by a ton (~$80). So most people dismissed the new findings as interesting, but not particularly impactful.

They're missing the point though. As Noah Smith articulated in his excellent tweet storm, CO2 Capture gets cheaper with scale, whereas the cost of reducing our emissions gets exponentially more expensive with every ton.

I'm cautiously optimistic about the potential of CO2 Capture — as a research field, and maybe even as an industry.
