2 There are a couple of fantastic essays on this very idea that are well worth reading. First, Langdon Winner, ‘Do artifacts have politics?’, Daedalus, vol. 109, no. 1, 1980, pp. 121–36, https://www.jstor.org/stable/20024652, which includes the example of Moses’ bridges.

9 According to Merriam–Webster. The Oxford English Dictionary’s definition makes more of the mathematical nature of algorithms: ‘a process or set of rules to be followed in calculations or other problem-solving operations, especially by a computer’.

10 There are lots of different ways you could group algorithms, and I have no doubt that some computer scientists will complain that this list is too simplistic. It’s true that a more exhaustive list would have included several other category headers: mapping, reduction, regression and clustering, to name a few. But in the end, I chose this particular set of categories – from Nicholas Diakopoulos, Algorithmic Accountability Reporting: On the Investigation of Black Boxes (New York: Tow Center for Digital Journalism, Columbia University, 2014) – as it does a great job at covering the basics and offers a useful way to demystify and distil a vast, complex area of study.

13 I say ‘in theory’ deliberately. The reality might be a little different. Some algorithms have been built over years by hundreds, even thousands, of developers, each incrementally adding their own steps to the process. As the lines of code grow, so does the complexity of the system, until the logical threads become like a tangled plate of spaghetti. Eventually, the algorithm becomes impossible to follow, and far too complicated for any one human to understand.
  In 2013 Toyota was ordered to pay $3 million in compensation after a fatal crash involving one of its vehicles. The car had accelerated uncontrollably, despite the driver having her foot on the brake rather than the throttle at the time. An expert witness told the jury that an unintended instruction, hidden deep within the vast tangled mess of software, was to blame. See Phil Koopman, A case study of Toyota unintended acceleration and software safety (Pittsburgh: Carnegie Mellon University, 18 Sept. 2014), https://users.ece.cmu.edu/~koopman/pubs/koopman14_toyota_ua_slides.pdf.

14 This illusion (the example here is taken from https://commons.wikimedia.org/wiki/File:Vase_of_rubin.png) is known as Rubin’s vase, after Edgar Rubin, who developed the idea. It is an example of an ambiguous image – right on the border between two shadowed faces looking towards each other, and an image of a white vase. As it’s drawn, it’s fairly easy to switch between the two in your mind, but all it would take is a couple of lines on the picture to push it in one direction or another. Perhaps a faint outline of the eyes on the faces, or the shadow on the neck of the vase.
  The dog/car example of image recognition is a similar story. The team found a picture that was right on the cusp between two different classifications and used the smallest perturbation possible to shift the image from one category to another in the eye of the machine.

11 Up to half of the judges differed in their opinion of the best course of action on any one case.

12 Statisticians have a way to measure this kind of consistency in judgments, called Cohen’s Kappa. It takes into account the fact that – even if you were just wildly guessing – you could end up being consistent by chance. A score of one means perfect consistency. A score of zero means you’re doing no better than random. The judges’ scores ranged from zero to one and averaged 0.69.

Burgess, ‘Factors determining success or failure on parole’, in The Workings of the Intermediate-sentence Law and Parole System in Illinois (Springfield, IL: State Board of Parole, 1928). It’s a tricky paper to track down, so here is an alternative read by Burgess’s colleague Tibbitts, on the follow-up study to the original: Clark Tibbitts, ‘Success or failure on parole can be predicted: a study of the records of 3,000 youths paroled from the Illinois State Reformatory’, Journal of Criminal Law and Criminology, vol. 22, no. 1, Spring 1931, https://scholarlycommons.law.northwestern.edu/cgi/viewcontent.cgi?article=2211&context=jclc. The other categories used by Burgess were ‘black sheep’, ‘criminal by accident’, ‘dope’ and ‘gangster’. ‘Farm boys’ were the category he found least likely to re-offend.

21 A slight caveat here: there probably is some selection bias in this statistic. ‘Ask the audience’ was typically used in the early rounds of the game, when the questions were a lot easier. None the less, the idea of the collective opinions of a group being more accurate than those of any individual is a well-documented phenomenon.

This study actually used ‘gradient boosted decision trees’, an algorithm similar to random forests. Both combine the predictions of lots of decision trees to arrive at a decision, but the trees in the gradient-boosted method are grown sequentially, while in random forests they are grown in parallel. To set up this study, the dataset was first chopped in half. One half was used to train the algorithm, the other half was kept to one side. Once the algorithm was ready, it took cases from the half that it had never seen before to try to predict what would happen. (Without splitting the data first, your algorithm would just be a fancy look-up table).

25 Academics have spent time developing statistical techniques to deal with precisely this issue, so that you can still make a meaningful comparison between the respective predictions made by judges and algorithms. For more details on this, see Kleinberg et al., Human Decisions and Machine Predictions.

According to a 2018 study, the COMPAS algorithm has a similar accuracy to an ‘ensemble’ of humans. The researchers demonstrated that asking a group of 20 inexperienced individuals to predict recidivism achieved an equivalent score to the COMPAS system. It’s an interesting comparison, but it’s worth remembering that in real courts, judges don’t have a team of strangers making votes in the back room. They’re on their own. And that’s the only comparison that really counts. See Julia Dressel and Hany Farid, ‘The accuracy, fairness, and limits of predicting recidivism’, Science Advances, vol. 4, no. 1, 2018.

39 Surprisingly, perhaps, Equivant’s stance on this is backed up by the Supreme Court of Wisconsin. After Eric Loomis was sentenced to prison for six years by a judge using the COMPAS risk-assessment tool, he appealed the ruling. The case, Loomis v. Wisconsin, claimed that the use of proprietary, closed-source risk-assessment software to determine his sentence violated his right to due process, because the defence can’t challenge the scientific validity of the score. But the Wisconsin Supreme Court ruled that a trial court’s use of an algorithmic risk assessment in sentencing did not violate the defendant’s due process rights: Supreme Court of Wisconsin, case no. 2015AP157-CR, opinion filed 13 July 2016, https://www.wicourts.gov/sc/opinion/DisplayDocument.pdf?content=pdf&seqNo=171690.

11 The name ‘neural network’ came about as an analogy with what happens in the brain. There, billions of neurons are connected to one another in a gigantic network. Each neuron listens to its connections and sends out a signal whenever it picks up on another neuron being excited. The signal then excites some other neurons that are listening to it.
  A neural network is a much simpler and more orderly version of the brain. Its (artificial) neurons are structured in layers, and all the neurons in each layer listen to all the neurons in the previous layer. In our dog example the very first layer is the individual pixels in the image. Then there are several layers with thousands of neurons in them, and a final layer with only a single neuron in it that outputs the probability that the image fed in is a dog.
  The procedure for updating the neurons is known as the ‘backpropagation algorithm’. We start with the final neuron that outputs the probability that the image is a dog. Let’s say we fed in an image of a dog and it predicted that the image had a 70 per cent chance of being a dog. It looks at the signals it received from the previous layer and says, ‘The next time I receive information like that I’ll increase my probability that the image is a dog’. It then says to each of the neurons in the previous layer, ‘Hey, if you’d given me this signal instead I would have made a better prediction’. Each of those neurons looks at its input signals and changes what it would output the next time. And then it tells the previous layer what signals it should have sent, and so on through all the layers back to the beginning. It is this process of propagating the errors back through the neural network that leads to the name ‘the backpropagation algorithm’.
  For a more detailed overview of neural networks, how they are built and trained, see Pedro Domingos, The Master Algorithm: How the Quest for the Ultimate Learning Machine Will Remake Our World (New York: Basic Books, 2015).

This particular algorithm is known as a convolutional neural network. Rather than the entire image being fed in, the algorithm first applies a host of different filters and looks for local patterns in the way the picture is distorted.

46 Even if you get around all of those issues, sometimes the data itself just doesn’t exist. There are thousands of rare diseases with an underlying genetic cause that are effectively unique. Doctors have enormous difficulty spotting one of these conditions because in many cases they will have never seen it before. All the algorithms in the world won’t solve issues with tiny sample sizes.

59 After having his DNA tested, the young man learned that a particular pattern on his Y-chromosome – passed from father to son – was also shared by two people with the same surname (distant relatives on his father’s side). That surname, together with the place and date of birth of his father, was enough to track him down.

47 Actually, Talley’s story is even more harrowing than the summary I’ve given here. After spending two months in jail for his initial arrest, Talley was released without charge. It was a year later – by which time he was living in a shelter – that he was arrested for a second time. This time the charges were not dropped, and the FBI testified against him. The case against him finally fell apart when the bank teller, who realized that Talley lacked the moles she’d seen on the robber’s hands as they passed over the counter, testified in court: ‘It’s not the guy who robbed me.’ He’s now suing for $10 million. For a full account, see Kofman, ‘How a facial recognition mismatch can ruin your life’.
