## Best Things of 2018

703 words

Not (best (things of 2018)) but ((best things) of 2018), because recommendations get more interesting if they are rate-limited and less interesting if a recency constraint is imposed.

#### Best interactive web essay

By internet creators Vi Hart and Nicky Case; Parable of the polygons. Cute little triangles and squares get segregated in ways none of them ever intended against their best wishes.

#### Best portrait article

Portraying one of the most important trans people of the past few years, Vice Broadly’s piece on Caitlyn Jenner was a nice read.

#### Best economist’s story

On why setting maximum prices is bad. They Clapped by Michael Munger. Very salient, go read it.

I see a lot of talks from computer science researchers, and CS people are surprisingly good at giving captivating talks. But, quoting Virginia Woolf,

[..] one must read [any book] as if it were the last volume in a fairly long series, continuing all those other books that I have been glancing at. For books continue each other, in spite of our habit of judging them separately.

Virginia Woolf, A Room of One’s Own, or page 52 in Penguin’s Vintage Mini “Liberty”

And so a talk must be considered in its social context. Based on this principle, the clear winner for this category is this keynote speech by James Mickens of Harvard University at USENIX Security 2018: Why Do Keynote Speakers Keep Suggesting That Improving Security Is Possible? Mickens is a captivating orator, the talk is funny and informative and gives a critical view on an important issue of the present day.

#### Best internet rabbit-hole

An old one for nostalgia. How to spot photo manipulation. Body By Victoria. Do click the links to follow-up posts, and the rest of the website is worth checking out as well.

#### Best description of psychologists

This text fragment reflects every interaction I’ve had with psychologists anywhere, both my gatekeepers and psychologists I visited for other reasons.

My anorexic patients sometimes complain of being forced into this mold. They’ll try to go to therapy for their inability to eat a reasonable amount of food, and their therapist will want to spend the whole time talking about their body image issues. When they complain they don’t really have body image issues, they’ll get accused of repressing it. Eventually they’ll just say “Yeah, whatever, I secretly wanted to be a ballerina” in order to make the therapist shut up and get to the part where maybe treatment happens.

#### Best video essay

This is not really a contest, Contrapoints’ The Aesthetic is the most beautiful piece of film I’ve seen in years. It is an honest expression of feelings and internal dialogue and conflict that trans women experience. It touches on so many uncomfortable issues without having any single clear message. Contrapoints raises the video essay to form of art. There is so much going on so many levels and I can just keep on watching the thing over and over again. Highly recommended watching for both trans and cis people.

The creator got quite some social media backlash on the video. There is exactly one reaction video that I felt was worth watching. Nobody Wins: ContraPoints, The Aesthetic, and Negative Representation by let’s talk about stuff. [This text essay is also pretty good. How Contrapoints Misunderstands Gender.]

#### Best book

My choice of best book for 2018 is Aphro-ism by Aph Ko and Syl Ko. It is a blog-turned-book, with a number of brilliant essays on, among others, veganism and social justice. I cannot overstate how much I like this book. I learned a lot from reading this book, and not just about the book’s subject matter.

The writings of the Ko sisters are very far from every thought I’ve ever had. This fact is reflected in how much I learned from the book, as well as in how difficult it was to understand it. I’ve re-listened this book 5 times by now. The first time, I understood literally nothing. Each time after that I understood a bit more, and I feel I understand most parts now. Not yet at the level of being to explain the ideas, but at the level of seeing good use value in them.

## On the value of anecdotes

331 words

What is better, if everyone is wrong about the same 2% of facts, or if everyone is wrong about a different 4% of facts? Depending on how you answer this question, you should act in very different ways. I’ll take vegan advocacy as an example, but the question can be applies more generally.

If you’re in the first group, you would prefer a scientific data-driven approach. You would experiment with many different approaches to advocacy, analyse the data to find the single best way of doing outreach, and make everyone in vegan activism aware that this is the best way to do it.

If you prefer the 4% case, a local algorithm is the way to go. Think about what drove you to become vegan, and continue this strategy. If you were shocked into becoming vegan by a Cube of Truth, you should be participating in Cubes of Truth. If you became vegan after your friendly vegan neighbour exemplified that veganism is a totally normal lifestyle and they allowed you to pick their brain about why they became vegan themselves, then you should become the friendly vegan acquaintance of the people you know yourself.

One interesting question if you enact the local algorithm, is how to weigh anecdotes. The local algorithm described above only considers your data; one alternative algorithm is to use the approach that was effective on the majority of your direct friends that became vegan before you. Another algorithm looks at all your the friends of your friends, or everyone within distance 3 in the friendship-graph. If everyone is connected by everyone by a friendship-path of length 6, then the distance 6 algorithm is exactly the data-driven approach from the second paragraph.

Evolutionary theory suggests that the small-distance algorithms are effective, for the best outreach strategy will eventually out-compete all others. But for the distance 0 or 1 cases, you’re basically working on anecdotal evidence. I’m not sure anymore what the correct value is to place on anecdotes.

## The life expectancy of trans women is not 35 years

904 wordsEvery once in a while I read an article or comment like this:

The average lifespan of trans women in the US is 35 years. Source

This number is wrong in so many ways, but many people seem to fall for it. The most viral variant consists of screencaps of this tumblr post.

Every murder is a tragedy, and it is particularly sad when someone gets murdered just for being trans. That is all the more reason to get our numbers right: exaggeration doesn’t help the cause. The lifespan statistic above is absurd. There is no way that they can be true, and it is telling of our maths and science education that people believe them.

Let’s do a basic sanity check on the 23-30 years figure. If 50% of trans folks would reach the age of 60, the other half would have to be dead by age 10. But measuring “age of death of trans people” is really tricky, because a person will only enter the trans population after transition: if they die before that, nobody knows they’re trans. So realistically, all trans people that die are at least 16 years old.  If the trans people who get murdered do so at the earliest possible age (16), how many trans people can maximally reach the age of 75? Well, we solve for the fraction $x$:$$75x + (1-x)*16=35.$$

Does one in 3 trans people get killed over their lives? Of course not. The only place the 23-30 year figure could realistically come from is if the number described life expectancy conditional on getting killed or some other low-probability conditional.

### Media reporting

Most journalists aren’t good with numbers. This effects their propensity to cite the low life expectancy for trans folks. The Guardian:

a 2014 report concluded that the average life expectancy of trans women in the Americas is between 30 and 35.

NPR:

“Transgender people have an average life expectancy of about 30 to 32 years,” Balestra says.

The statistic said the average life expectancy for a trans woman of color is 35.

The difference is striking. “transgender people”, “trans women in the US”, “trans women in the Americas”, “trans women of colour”. They’re all misreporting the same in number in different messed up ways.

The first popular English medium to cover the number, and the source that most chains of web pages end up on, is Washington Blade, which reports one realistic number and also the unrealistic one.

The commission indicates 80 percent of trans murder victims in the Americas during the 15-month period were 35 years old or younger. Its report further concludes the average life expectancy of trans people in the Western Hemisphere is between 30-35 years.

Washington Blade cites a report by the Inter-American Commission on Human Rights of the Organisation of American States (press release, report). The report mentions this

According to the data collected in the Registry of Violence, eighty percent of trans persons killed were 35 years of age or younger.

The data (xlsx, Spanish) contains 770 reports of violence against LGBT people from a lot of countries in the Americas, all incidents happened in the 15 months between January 1st 2013 and March 31st 2014. Not all countries are in the dataset and no skin colours of the victims are listed, but are. Some victims are deadnamed, others appropriately named. Searching the names online, there are indeed a lot of trans women of colour among the listed US victims.

The data contain 282 murders on trans people, of which 212 have an age of death attached. The average age of death among those 212 is 28.7. Among 14 murder cases in the US, all trans women, the average age was 29.8. Filtering the America-wide data for listed ages of murder of 35 and under, we find 168 cases, and 168 out of 212 is 80%. This is the source of the 80% vs 35 years claim, but keep in mind that this is as a fraction of cases that have ages attached to them.

Where does the life expectancy of 30-35 years come from? The IACHR report just says this:

In terms of the age of the victims, the IACHR notes that while it seems gay men of all ages are targeted, in the case of trans women, it is mostly younger trans women who are victims of violence. In this regard, the IACHR has received information that the life expectancy of trans women in the Americas is between 30 and 35 years of age.

No source is listed. I’m calling bullshit. There is no way that getting murdered reduces life expectancy by at most 5 years.

### Section of doubt

The 1 in 12 murder rate up top is interesting because it cannot be refuted in a conservative street-fighting calculation.  The US has 325 million citizens and a life expectancy of 79 years, so every year roughly 4.1 million US citizens die. If 1 in 40000 people is trans, then you’d expect 100 US trans people to die each year. 2018’s TDOR has 23 murder cases from the US listed, so we’d estimate that trans people have a 1 in 4 probability of death by murder, not accounting for skin color.

I don’t trust the 1:40000 statistic within an order of magnitude, but it is an often cited one. So while I don’t take the 1:4 number to be remotely close to the truth, it is understandable if people believe the 1 in 12 figure.
