UnitedHealth faces class action lawsuit over algorithmic care denials in Medicare Advantage plans

Casey Ross and Bob Herman
Originally posted 14 Nov 23

A class action lawsuit was filed Tuesday against UnitedHealth Group and a subsidiary alleging that they are illegally using an algorithm to deny rehabilitation care to seriously ill patients, even though the companies know the algorithm has a high error rate.

The class action suit, filed on behalf of deceased patients who had a UnitedHealthcare Medicare Advantage plan and their families by the California-based Clarkson Law Firm, follows the publication of a STAT investigation Tuesday. The investigation, cited by the lawsuit, found UnitedHealth pressured medical employees to follow an algorithm, which predicts a patient’s length of stay, to issue payment denials to people with Medicare Advantage plans. Internal documents revealed that managers within the company set a goal for clinical employees to keep patients rehab stays within 1% of the days projected by the algorithm.

The lawsuit, filed in the U.S. District Court of Minnesota, accuses UnitedHealth and its subsidiary, NaviHealth, of using the computer algorithm to “systematically deny claims” of Medicare beneficiaries struggling to recover from debilitating illnesses in nursing homes. The suit also cites STAT’s previous reporting on the issue.

“The fraudulent scheme affords defendants a clear financial windfall in the form of policy premiums without having to pay for promised care,” the complaint alleges. “The elderly are prematurely kicked out of care facilities nationwide or forced to deplete family savings to continue receiving necessary care, all because an [artificial intelligence] model ‘disagrees’ with their real live doctors’ recommendations.”

Here are some of my concerns:

The use of algorithms in healthcare decision-making has raised a number of ethical concerns. Some critics argue that algorithms can be biased and discriminatory, and that they can lead to decisions that are not in the best interests of patients. Others argue that algorithms can lack transparency, and that they can make it difficult for patients to understand how decisions are being made.

The lawsuit against UnitedHealth raises a number of specific ethical concerns. First, the plaintiffs allege that UnitedHealth's algorithm is based on inaccurate and incomplete data. This raises the concern that the algorithm may be making decisions that are not based on sound medical evidence. Second, the plaintiffs allege that UnitedHealth has failed to adequately train its employees on how to use the algorithm. This raises the concern that employees may be making decisions that are not in the best interests of patients, either because they do not understand how the algorithm works or because they are pressured to deny claims.

The lawsuit also raises the general question of whether algorithms should be used to make healthcare decisions. Some argue that algorithms can be used to make more efficient and objective decisions than humans can. Others argue that algorithms are not capable of making complex medical decisions that require an understanding of the individual patient's circumstances.

The use of algorithms in healthcare is a complex issue with no easy answers. It is important to carefully consider the potential benefits and risks of using algorithms before implementing them in healthcare settings.

AI’s fairness problem: understanding wrongful discrimination in the context of automated decision-making

Cossette-Lefebvre, H., Maclure, J. 
AI Ethics (2022).


The use of predictive machine learning algorithms is increasingly common to guide or even take decisions in both public and private settings. Their use is touted by some as a potentially useful method to avoid discriminatory decisions since they are, allegedly, neutral, objective, and can be evaluated in ways no human decisions can. By (fully or partly) outsourcing a decision process to an algorithm, it should allow human organizations to clearly define the parameters of the decision and to, in principle, remove human biases. Yet, in practice, the use of algorithms can still be the source of wrongful discriminatory decisions based on at least three of their features: the data-mining process and the categorizations they rely on can reconduct human biases, their automaticity and predictive design can lead them to rely on wrongful generalizations, and their opaque nature is at odds with democratic requirements. We highlight that the two latter aspects of algorithms and their significance for discrimination are too often overlooked in contemporary literature. Though these problems are not all insurmountable, we argue that it is necessary to clearly define the conditions under which a machine learning decision tool can be used. We identify and propose three main guidelines to properly constrain the deployment of machine learning algorithms in society: algorithms should be vetted to ensure that they do not unduly affect historically marginalized groups; they should not systematically override or replace human decision-making processes; and the decision reached using an algorithm should always be explainable and justifiable.

From the Conclusion

Given that ML algorithms are potentially harmful because they can compound and reproduce social inequalities, and that they rely on generalization disregarding individual autonomy, then their use should be strictly regulated. Yet, these potential problems do not necessarily entail that ML algorithms should never be used, at least from the perspective of anti-discrimination law. Rather, these points lead to the conclusion that their use should be carefully and strictly regulated. However, before identifying the principles which could guide regulation, it is important to highlight two things. First, the context and potential impact associated with the use of a particular algorithm should be considered. Anti-discrimination laws do not aim to protect from any instances of differential treatment or impact, but rather to protect and balance the rights of implicated parties when they conflict [18, 19]. Hence, using ML algorithms in situations where no rights are threatened would presumably be either acceptable or, at least, beyond the purview of anti-discriminatory regulations.

Second, one also needs to take into account how the algorithm is used and what place it occupies in the decision-making process. More precisely, it is clear from what was argued above that fully automated decisions, where a ML algorithm makes decisions with minimal or no human intervention in ethically high stakes situation—i.e., where individual rights are potentially threatened—are presumably illegitimate because they fail to treat individuals as separate and unique moral agents. To avoid objectionable generalization and to respect our democratic obligations towards each other, a human agent should make the final decision—in a meaningful way which goes beyond rubber-stamping—or a human agent should at least be in position to explain and justify the decision if a person affected by it asks for a revision. If this does not necessarily preclude the use of ML algorithms, it suggests that their use should be inscribed in a larger, human-centric, democratic process.

Robots became racist after AI training, always chose Black faces as ‘criminals’

Originally posted 16 JUL 22

As part of a recent experiment, scientists asked specially programmed robots to scan blocks with people’s faces on them, then put the “criminal” in a box. The robots repeatedly chose a block with a Black man’s face.

Those virtual robots, which were programmed with a popular artificial intelligence algorithm, were sorting through billions of images and associated captions to respond to that question and others, and may represent the first empirical evidence that robots can be sexist and racist, according to researchers. Over and over, the robots responded to words like “homemaker” and “janitor” by choosing blocks with women and people of color.

The study, released last month and conducted by institutions including Johns Hopkins University and the Georgia Institute of Technology, shows the racist and sexist biases baked into artificial intelligence systems can translate into robots that use them to guide their operations.

Companies have been pouring billions of dollars into developing more robots to help replace humans for tasks such as stocking shelves, delivering goods or even caring for hospital patients. Heightened by the pandemic and a resulting labor shortage, experts describe the current atmosphere for robotics as something of a gold rush. But tech ethicists and researchers are warning that the quick adoption of the new technology could result in unforeseen consequences down the road as the technology becomes more advanced and ubiquitous.

“With coding, a lot of times you just build the new software on top of the old software,” said Zac Stewart Rogers, a supply chain management professor from Colorado State University. “So, when you get to the point where robots are doing more … and they’re built on top of flawed roots, you could certainly see us running into problems.”

Researchers in recent years have documented multiple cases of biased artificial intelligence algorithms. That includes crime prediction algorithms unfairly targeting Black and Latino people for crimes they did not commit, as well as facial recognition systems having a hard time accurately identifying people of color.

Why it’s so damn hard to make AI fair and unbiased

Sigal Samuel
Originally posted 19 APR 2022

Here is an excerpt:

So what do big players in the tech space mean, really, when they say they care about making AI that’s fair and unbiased? Major organizations like Google, Microsoft, even the Department of Defense periodically release value statements signaling their commitment to these goals. But they tend to elide a fundamental reality: Even AI developers with the best intentions may face inherent trade-offs, where maximizing one type of fairness necessarily means sacrificing another.

The public can’t afford to ignore that conundrum. It’s a trap door beneath the technologies that are shaping our everyday lives, from lending algorithms to facial recognition. And there’s currently a policy vacuum when it comes to how companies should handle issues around fairness and bias.

“There are industries that are held accountable,” such as the pharmaceutical industry, said Timnit Gebru, a leading AI ethics researcher who was reportedly pushed out of Google in 2020 and who has since started a new institute for AI research. “Before you go to market, you have to prove to us that you don’t do X, Y, Z. There’s no such thing for these [tech] companies. So they can just put it out there.”

That makes it all the more important to understand — and potentially regulate — the algorithms that affect our lives. So let’s walk through three real-world examples to illustrate why fairness trade-offs arise, and then explore some possible solutions.

How would you decide who should get a loan?

Here’s another thought experiment. Let’s say you’re a bank officer, and part of your job is to give out loans. You use an algorithm to help you figure out whom you should loan money to, based on a predictive model — chiefly taking into account their FICO credit score — about how likely they are to repay. Most people with a FICO score above 600 get a loan; most of those below that score don’t.

One type of fairness, termed procedural fairness, would hold that an algorithm is fair if the procedure it uses to make decisions is fair. That means it would judge all applicants based on the same relevant facts, like their payment history; given the same set of facts, everyone will get the same treatment regardless of individual traits like race. By that measure, your algorithm is doing just fine.

But let’s say members of one racial group are statistically much more likely to have a FICO score above 600 and members of another are much less likely — a disparity that can have its roots in historical and policy inequities like redlining that your algorithm does nothing to take into account.

Another conception of fairness, known as distributive fairness, says that an algorithm is fair if it leads to fair outcomes. By this measure, your algorithm is failing, because its recommendations have a disparate impact on one racial group versus another.

The human black-box: The illusion of understanding human better than algorithmic decision-making

Bonezzi, A., Ostinelli, M., & Melzner, J. (2022). 
Journal of Experimental Psychology: General.


As algorithms increasingly replace human decision-makers, concerns have been voiced about the black-box nature of algorithmic decision-making. These concerns raise an apparent paradox. In many cases, human decision-makers are just as much of a black-box as the algorithms that are meant to replace them. Yet, the inscrutability of human decision-making seems to raise fewer concerns. We suggest that one of the reasons for this paradox is that people foster an illusion of understanding human better than algorithmic decision-making, when in fact, both are black-boxes. We further propose that this occurs, at least in part, because people project their own intuitive understanding of a decision-making process more onto other humans than onto algorithms, and as a result, believe that they understand human better than algorithmic decision-making, when in fact, this is merely an illusion.

General Discussion

Our work contributes to prior literature in two ways. First, it bridges two streams of research that have thus far been considered in isolation: IOED (Illusion of Explanatory Depth) (Rozenblit & Keil, 2002) and projection (Krueger,1998). IOED has mostly been documented for mechanical devices and natural phenomena and has been attributed to people confusing a superficial understanding of what something does for how it does it (Keil, 2003). Our research unveils a previously unexplored driver ofIOED, namely, the tendency to project one’s own cognitions on to others, and in so doing extends the scope of IOED to human deci-sion-making. Second, our work contributes to the literature on clinical versus statistical judgments (Meehl, 1954). Previous research shows that people tend to trust humans more than algorithms (Dietvorst et al., 2015). Among the many reasons for this phenomenon (see Grove & Meehl, 1996), one is that people do not understand how algorithms work (Yeomans et al., 2019). Our research suggests that people’s distrust toward algorithms may stem not only from alack of understanding how algorithms work but also from an illusion of understanding how their human counterparts operate.

Our work can be extended by exploring other consequences and psychological processes associated with the illusion of understand-ing humans better than algorithms. As for consequences, more research is needed to explore how illusory understanding affects trust in humans versus algorithms. Our work suggests that the illusion of understanding humans more than algorithms can yield greater trust in decisions made by humans. Yet, to the extent that such an illusion stems from a projection mechanism, it might also lead to favoring algorithms over humans, depending on the underly-ing introspections. Because people’s introspections can be fraught with biases and idiosyncrasies they might not even be aware of (Nisbett & Wilson, 1977;Wilson, 2004), people might erroneously project these same biases and idiosyncrasies more onto other humans than onto algorithms and consequently trust those humans less than algorithms. To illustrate, one might expect a recruiter to favor people of the same gender or ethnic background just because one may be inclined to do so. In these circumstances, the illusion to understand humans better than algorithms might yield greater trust in algorithmic than human decisions (Bonezzi & Ostinelli, 2021).

Understanding, explaining, and utilizing medical artificial intelligence

Cadario, R., Longoni, C. & Morewedge, C.K. 
Nat Hum Behav (2021). 


Medical artificial intelligence is cost-effective and scalable and often outperforms human providers, yet people are reluctant to use it. We show that resistance to the utilization of medical artificial intelligence is driven by both the subjective difficulty of understanding algorithms (the perception that they are a ‘black box’) and by an illusory subjective understanding of human medical decision-making. In five pre-registered experiments (1–3B: N = 2,699), we find that people exhibit an illusory understanding of human medical decision-making (study 1). This leads people to believe they better understand decisions made by human than algorithmic healthcare providers (studies 2A,B), which makes them more reluctant to utilize algorithmic than human providers (studies 3A,B). Fortunately, brief interventions that increase subjective understanding of algorithmic decision processes increase willingness to utilize algorithmic healthcare providers (studies 3A,B). A sixth study on Google Ads for an algorithmic skin cancer detection app finds that the effectiveness of such interventions generalizes to field settings (study 4: N = 14,013).

From the Discussion

Utilization of algorithmic-based healthcare services is becoming critical with the rise of telehealth service, the current surge in healthcare demand and long-term goals of providing affordable and high-quality healthcare in developed and developing nations. Our results yield practical insights for reducing reluctance to utilize medical AI. Because the technologies used in algorithmic-based medical applications are complex, providers tend to present AI provider decisions as a ‘black box’. Our results underscore the importance of recent policy recommendations to open this black box to patients and users. A simple one-page visual or sentence that explains the criteria or process used to make medical decisions increased acceptance of an algorithm-based skin cancer diagnostic tool, which could be easily adapted to other domains and procedures.

Given the complexity of the process by which medical AI makes decisions, firms now tend to emphasize the outcomes that algorithms produce in their marketing to consumers, which feature benefits such as accuracy, convenience and rapidity (performance), while providing few details about how algorithms work (process). Indeed, in an ancillary study examining the marketing of skin cancer smartphone applications (Supplementary Appendix 8), we find that performance-related keywords were used to describe 57–64% of the applications, whereas process-related keywords were used to describe 21% of the applications. Improving subjective understanding of how medical AI works may then not only provide beneficent insights for increasing consumer adoption but also for firms seeking to improve their positioning. Indeed, we find increased advertising efficacy for SkinVision, a skin cancer detection app, when advertising included language explaining how it works.

Should we be concerned that the decisions of AIs are inscrutable?

John Zerilli
Originally published 14 June 21

Here is an excerpt:

However, there’s a danger of carrying reliabilist thinking too far. Compare a simple digital calculator with an instrument designed to assess the risk that someone convicted of a crime will fall back into criminal behaviour (‘recidivism risk’ tools are being used all over the United States right now to help officials determine bail, sentencing and parole outcomes). The calculator’s outputs are so dependable that an explanation of them seems superfluous – even for the first-time homebuyer whose mortgage repayments are determined by it. One might take issue with other aspects of the process – the fairness of the loan terms, the intrusiveness of the credit rating agency – but you wouldn’t ordinarily question the engineering of the calculator itself.

That’s utterly unlike the recidivism risk tool. When it labels a prisoner as ‘high risk’, neither the prisoner nor the parole board can be truly satisfied until they have some grasp of the factors that led to it, and the relative weights of each factor. Why? Because the assessment is such that any answer will necessarily be imprecise. It involves the calculation of probabilities on the basis of limited and potentially poor-quality information whose very selection is value-laden.

But what if systems such as the recidivism tool were in fact more like the calculator? For argument’s sake, imagine a recidivism risk-assessment tool that was basically infallible, a kind of Casio-cum-Oracle-of-Delphi. Would we still expect it to ‘show its working’?

This requires us to think more deeply about what it means for an automated decision system to be ‘reliable’. It’s natural to think that such a system would make the ‘right’ recommendations, most of the time. But what if there were no such thing as a right recommendation? What if all we could hope for were only a right way of arriving at a recommendation – a right way of approaching a given set of circumstances? This is a familiar situation in law, politics and ethics. Here, competing values and ethical frameworks often produce very different conclusions about the proper course of action. There are rarely unambiguously correct outcomes; instead, there are only right ways of justifying them. This makes talk of ‘reliability’ suspect. For many of the most morally consequential and controversial applications of ML, to know that an automated system works properly just is to know and be satisfied with its reasons for deciding.

Moral zombies: why algorithms are not moral agents

Véliz, C. 
AI & Soc (2021). 


In philosophy of mind, zombies are imaginary creatures that are exact physical duplicates of conscious subjects for whom there is no first-personal experience. Zombies are meant to show that physicalism—the theory that the universe is made up entirely out of physical components—is false. In this paper, I apply the zombie thought experiment to the realm of morality to assess whether moral agency is something independent from sentience. Algorithms, I argue, are a kind of functional moral zombie, such that thinking about the latter can help us better understand and regulate the former. I contend that the main reason why algorithms can be neither autonomous nor accountable is that they lack sentience. Moral zombies and algorithms are incoherent as moral agents because they lack the necessary moral understanding to be morally responsible. To understand what it means to inflict pain on someone, it is necessary to have experiential knowledge of pain. At most, for an algorithm that feels nothing, ‘values’ will be items on a list, possibly prioritised in a certain way according to a number that represents weightiness. But entities that do not feel cannot value, and beings that do not value cannot act for moral reasons.


This paper has argued that moral zombies—creatures that behave like moral agents but lack sentience—are incoherent as moral agents. Only beings who can experience pain and pleasure can understand what it means to inflict pain or cause pleasure, and only those with this moral understanding can be moral agents. What I have dubbed ‘moral zombies’ are relevant because they are similar to algorithms in that they make moral decisions as human beings would—determining who gets which benefits and penalties—without having any concomitant sentience.

There might come a time when AI becomes so sophisticated that robots might possess desires and values of their own. It will not, however, be on account of their computational prowess, but on account of their sentience, which may in turn require some kind of embodiment. At present, we are far from creating sentient algorithms.

When algorithms cause moral havoc, as they often do, we must look to the human beings who designed, programmed, commissioned, implemented, and were supposed to supervise them to assign the appropriate blame. For all their complexity and flair, algorithms are nothing but tools, and moral agents are fully responsible for the tools they create and use.

When eliminating bias isn’t fair: Algorithmic reductionism and procedural justice in human resource decisions

Newman, D., Fast, N. and Harmon, D.
Organizational Behavior and 
Human Decision Processes
Volume 160, September 2020, Pages 149-167


The perceived fairness of decision-making procedures is a key concern for organizations, particularly when evaluating employees and determining personnel outcomes. Algorithms have created opportunities for increasing fairness by overcoming biases commonly displayed by human decision makers. However, while HR algorithms may remove human bias in decision making, we argue that those being evaluated may perceive the process as reductionistic, leading them to think that certain qualitative information or contextualization is not being taken into account. We argue that this can undermine their beliefs about the procedural fairness of using HR algorithms to evaluate performance by promoting the assumption that decisions made by algorithms are based on less accurate information than identical decisions made by humans. Results from four laboratory experiments (N = 798) and a large-scale randomized experiment in an organizational setting (N = 1654) confirm this hypothesis. Theoretical and practical implications for organizations using algorithms and data analytics are discussed.


• Algorithmic decisions are perceived as less fair than identical decisions by humans.

• Perceptions of reductionism mediate the adverse effect of algorithms on fairness.

• Algorithmic reductionism comes in two forms: quantification and decontextualization.

• Employees voice lower organizational commitment when evaluated by algorithms.

• Perceptions of unfairness mediate the adverse effect of algorithms on commitment.


Perceived unfairness notwithstanding, algorithms continue to gain increasing influence in human affairs, not only in organizational settings but throughout our social and personal lives. How this influence plays out against our sense of fairness remains to be seen but should undoubtedly be of central interest to justice scholars in the years ahead.  Will the compilers of analytics and writers of algorithms adapt their
methods to comport with intuitive notions of morality? Or will our understanding of fairness adjust to the changing times, becoming inured to dehumanization in an ever more impersonal world? Questions
such as these will be asked more and more frequently as technology reshapes modes of interaction and organization that have held sway for generations. We have sought to contribute answers to these questions,
and we hope that our work will encourage others to continue studying these and related topics.

Amazon Halts Police Use Of Its Facial Recognition Technology

Originally posted 10 June 20

Amazon announced on Wednesday a one-year moratorium on police use of its facial-recognition technology, yielding to pressure from police-reform advocates and civil rights groups.

It is unclear how many law enforcement agencies in the U.S. deploy Amazon's artificial intelligence tool, but an official with the Washington County Sheriff's Office in Oregon confirmed that it will be suspending its use of Amazon's facial recognition technology.

Researchers have long criticized the technology for producing inaccurate results for people with darker skin. Studies have also shown that the technology can be biased against women and younger people.

IBM said earlier this week that it would quit the facial-recognition business altogether. In a letter to Congress, chief executive Arvind Krishna condemned software that is used "for mass surveillance, racial profiling, violations of basic human rights and freedoms."

And Microsoft President Brad Smith told The Washington Post during a livestream Thursday morning that his company has not been selling its technology to law enforcement. Smith said he has no plans to until there is a national law.

Racial bias skews algorithms widely used to guide care from heart surgery to birth, study finds

Sharon Begley
Originally posted 17 June 20

Here is an excerpt:

All 13 of the algorithms Jones and his colleagues examined offered rationales for including race in a way that, presumably unintentionally, made Black and, in some cases, Latinx patients less likely to receive appropriate care. But when you trace those rationales back to their origins, Jones said, “you find outdated science or biased data,” such as simplistically concluding that poor outcomes for Black patients are due to race.

Typically, developers based their algorithms on studies showing a correlation between race and some medical outcome, assuming race explained or was even the cause of, say, a poorer outcome (from a vaginal birth after a cesarean, say). They generally did not examine whether factors that typically go along with race in the U.S., such as access to primary care or socioeconomic status or discrimination, might be the true drivers of the correlation.

“Modern tools of epidemiology and statistics could sort that out,” Jones said, “and show that much of what passes for race is actually about class and poverty.”

Including race in a clinical algorithm can sometimes be appropriate, Powers cautioned: “It could lead to better patient care or even be a tool for addressing inequities.” But it might also exacerbate inequities. Figuring out the algorithms’ consequences “requires taking a close look at how the algorithm was trained, the data used to make predictions, the accuracy of those predictions, and how the algorithm is used in practice,” Powers said. “Unfortunately, we don’t have these answers for many of the algorithms.”

Freedom in an Age of Algocracy

John Danaher
forthcoming in Oxford Handbook on the Philosophy of Technology
edited by Shannon Vallor


There is a growing sense of unease around algorithmic modes of governance ('algocracies') and their impact on freedom. Contrary to the emancipatory utopianism of digital enthusiasts, many now fear that the rise of algocracies will undermine our freedom. Nevertheless, there has been some struggle to explain exactly how this will happen. This chapter tries to address the shortcomings in the existing discussion by arguing for a broader conception/understanding of freedom as well as a broader conception/understanding of algocracy. Broadening the focus in this way enables us to see how algorithmic governance can be both emancipatory and enslaving, and provides a framework for future development and activism around the creation of this technology.

From the Conclusion:

Finally, I’ve outlined a framework for thinking about the likely impact of algocracy on freedom. Given the complexity of freedom and the complexity of algocracy, I’ve argued that there is unlikely to be a simple global assessment of the freedom-promoting or undermining power of algocracy. This is something that has to be assessed and determined on a case-by-case basis. Nevertheless, there are at least five interesting and relatively novel mechanisms through which algocratic systems can both promote and undermine freedom. We should pay attention to these different mechanisms, but do so in a properly contextualized manner, and not by ignoring the pre-existing mechanisms through which freedom is undermined and promoted.

Will Past Criminals Reoffend? (Humans are Terrible at Predicting; Algorithms Worse)

Sophie Bushwick
Scientific American
Originally published 14 Feb 2020

Here is an excerpt:

Based on the wider variety of experimental conditions, the new study concluded that algorithms such as COMPAS and LSI-R are indeed better than humans at predicting risk. This finding makes sense to Monahan, who emphasizes how difficult it is for people to make educated guesses about recidivism. “It’s not clear to me how, in real life situations—when actual judges are confronted with many, many things that could be risk factors and when they’re not given feedback—how the human judges could be as good as the statistical algorithms,” he says. But Goel cautions that his conclusion does not mean algorithms should be adopted unreservedly. “There are lots of open questions about the proper use of risk assessment in the criminal justice system,” he says. “I would hate for people to come away thinking, ‘Algorithms are better than humans. And so now we can all go home.’”

Goel points out that researchers are still studying how risk-assessment algorithms can encode racial biases. For instance, COMPAS can say whether a person might be arrested again—but one can be arrested without having committed an offense. “Rearrest for low-level crime is going to be dictated by where policing is occurring,” Goel says, “which itself is intensely concentrated in minority neighborhoods.” Researchers have been exploring the extent of bias in algorithms for years. Dressel and Farid also examined such issues in their 2018 paper. “Part of the problem with this idea that you're going to take the human out of [the] loop and remove the bias is: it’s ignoring the big, fat, whopping problem, which is the historical data is riddled with bias—against women, against people of color, against LGBTQ,” Farid says.

Artificial Intelligence in Health Care

M. Matheny, D. Whicher, & S. Israni
JAMA. 2020;323(6):509-510.

The promise of artificial intelligence (AI) in health care offers substantial opportunities to improve patient and clinical team outcomes, reduce costs, and influence population health. Current data generation greatly exceeds human cognitive capacity to effectively manage information, and AI is likely to have an important and complementary role to human cognition to support delivery of personalized health care.  For example, recent innovations in AI have shown high levels of accuracy in imaging and signal detection tasks and are considered among the most mature tools in this domain.

However, there are challenges in realizing the potential for AI in health care. Disconnects between reality and expectations have led to prior precipitous declines in use of the technology, termed AI winters, and another such event is possible, especially in health care.  Today, AI has outsized market expectations and technology sector investments. Current challenges include using biased data for AI model development, applying AI outside of populations represented in the training and validation data sets, disregarding the effects of possible unintended consequences on care or the patient-clinician relationship, and limited data about actual effects on patient outcomes and cost of care.

AI in Healthcare: The Hope, The Hype, The Promise, The Peril, a publication by the National Academy of Medicine (NAM), synthesizes current knowledge and offers a reference document for the responsible development, implementation, and maintenance of AI in the clinical enterprise.  The publication outlines current and near-term AI solutions; highlights the challenges, limitations, and best practices for AI development, adoption, and maintenance; presents an overview of the legal and regulatory landscape for health care AI; urges the prioritization of equity, inclusion, and a human rights lens for this work; and outlines considerations for moving forward. This Viewpoint shares highlights from the NAM publication.

Slow response times undermine trust in algorithmic (but not human) predictions

E Efendic, P van de Calseyde, & A Evans
PsyArXiv PrePrints
Lasted Edited 22 Jan 20


Algorithms consistently perform well on various prediction tasks, but people often mistrust their advice. Here, we demonstrate one component that affects people’s trust in algorithmic predictions: response time. In seven studies (total N = 1928 with 14,184 observations), we find that people judge slowly generated predictions from algorithms as less accurate and they are less willing to rely on them. This effect reverses for human predictions, where slowly generated predictions are judged to be more accurate. In explaining this asymmetry, we find that slower response times signal the exertion of effort for both humans and algorithms. However, the relationship between perceived effort and prediction quality differs for humans and algorithms. For humans, prediction tasks are seen as difficult and effort is therefore positively correlated with the perceived quality of predictions. For algorithms, however, prediction tasks are seen as easy and effort is therefore uncorrelated to the quality of algorithmic predictions. These results underscore the complex processes and dynamics underlying people’s trust in algorithmic (and human) predictions and the cues that people use to evaluate their quality.

General discussion 

When are people reluctant to trust algorithm-generated advice? Here, we demonstrate that it depends on the algorithm’s response time. People judged slowly (vs. quickly) generated predictions by algorithms as being of lower quality. Further, people were less willing to use slowly generated algorithmic predictions. For human predictions, we found the opposite: people judged slow human-generated predictions as being of higher quality. Similarly, they were more likely to use slowly generated human predictions. 

We find that the asymmetric effects of response time can be explained by different expectations of task difficulty for humans vs. algorithms. For humans, slower responses were congruent with expectations; the prediction task was presumably difficult so slower responses, and more effort, led people to conclude that the predictions were high quality. For algorithms, slower responses were incongruent with expectations; the prediction task was presumably easy so slower speeds, and more effort, were unrelated to prediction quality.

Data Is an Asset, and It Must Have Values

Already, 22% of U.S. companies have attributed part of their profits to AI and advanced cases of (AI infused) predictive analytics.

According to a recent study SAP conducted in conjunction with the Economist’s Intelligent Unit, organizations doing the most with machine learning have experienced 43% more growth on average versus those who aren’t using AI and ML at all — or not using AI well.

One of their secrets: They treat data as an asset. The same way organizations treat inventory, fleet, and manufacturing assets.

They start with clear data governance with executive ownership and accountability (for a concrete example of how this looks, here are some principles and governance models that we at SAP apply in our daily work).

So, do treat data as an asset, because, no matter how powerful the algorithm, poor training data will limit the effectiveness of Artificial Intelligence and Predictive Analytics.

Bias in algorithmic filtering and personalization

Engin Bozdag
Ethics Inf Technol (2013) 15: 209.


Online information intermediaries such as Facebook and Google are slowly replacing traditional media channels thereby partly becoming the gatekeepers of our society. To deal with the growing amount of information on the social web and the burden it brings on the average user, these gatekeepers recently started to introduce personalization features, algorithms that filter information per individual. In this paper we show that these online services that filter information are not merely algorithms. Humans not only affect the design of the algorithms, but they also can manually influence the filtering process even when the algorithm is operational. We further analyze filtering processes in detail, show how personalization connects to other filtering techniques, and show that both human and technical biases are present in today’s emergent gatekeepers. We use the existing literature on gatekeeping and search engine bias and provide a model of algorithmic gatekeeping.

From the Discussion:

Today information seeking services can use interpersonal contacts of users in order to tailor information and to increase relevancy. This not only introduces bias as our model shows, but it also has serious implications for other human values, including user autonomy, transparency, objectivity, serendipity, privacy and trust. These values introduce ethical questions. Do private companies that are
offering information services have a social responsibility, and should they be regulated? Should they aim to promote values that the traditional media was adhering to, such as transparency, accountability and answerability? How can a value such as transparency be promoted in an algorithm?  How should we balance between autonomy and serendipity and between explicit and implicit personalization? How should we define serendipity? Should relevancy be defined as what is popular in a given location or by what our primary groups find interesting? Can algorithms truly replace human filterers?

Artificial Intelligence Is Superseding Well-Paying Wall Street Jobs

Compliance people run the risk of being replaced too. “As bad actors become more sophisticated, it is vital that financial regulators have the funding resources, technological capacity and access to AI and automated technologies to be a strong and effective cop on the beat,” said Martina Rejsjö, head of Nasdaq Surveillance North America Equities.

Nasdaq, a tech-driven trading platform, has an associated regulatory body that offers over 40 different algorithms, using 35,000 parameters, to spot possible market abuse and manipulation in real time. “The massive and, in many cases, exponential growth in market data is a significant challenge for surveillance professionals," Rejsjö said. “Market abuse attempts have become more sophisticated, putting more pressure on surveillance teams to find the proverbial needle in the data haystack." In layman's terms, she believes that the future is in tech overseeing trading activities, as the human eye is unable to keep up with the rapid-fire, sophisticated global trading dominated by algorithms.

When people say not to worry, that’s the precise time to worry. Companies—whether they are McDonald’s, introducing self-serve kiosks and firing hourly workers to cut costs, or top-tier investment banks that rely on software instead of traders to make million-dollar bets on the stock market—will continue to implement technology and downsize people in an effort to enhance profits and cut down on expenses. This trend will be hard to stop and have serious future consequences for the workers at all levels and salaries.

Robots in Finance Could Wipe Out Some of Its Highest-Paying Jobs

Robots have replaced thousands of routine jobs on Wall Street. Now, they’re coming for higher-ups.

That’s the contention of Marcos Lopez de Prado, a Cornell University professor and the former head of machine learning at AQR Capital Management LLC, who testified in Washington on Friday about the impact of artificial intelligence on capital markets and jobs. The use of algorithms in electronic markets has automated the jobs of tens of thousands of execution traders worldwide, and it’s also displaced people who model prices and risk or build investment portfolios, he said.

“Financial machine learning creates a number of challenges for the 6.14 million people employed in the finance and insurance industry, many of whom will lose their jobs -- not necessarily because they are replaced by machines, but because they are not trained to work alongside algorithms,” Lopez de Prado told the U.S. House Committee on Financial Services.

During the almost two-hour hearing, lawmakers asked experts about racial and gender bias in AI, competition for highly skilled technology workers, and the challenges of regulating increasingly complex, data-driven financial markets.

Will The Future of Work Be Ethical?

AI and climate: in a sense, you’ve already dealt with this new field people are calling the ethics of technology. When you hear that term, what comes to mind?

As a consumer of a lot of technology and as someone of the generation who has grown up with a phone in my hand, I’m aware my data is all over the internet. I’ve had conversations [with friends] about personal privacy and if I look around the classroom, most people have covers for the cameras on their computers. This generation is already aware [of] ethics whenever you’re talking about computing and the use of computers.

About AI specifically, as someone who’s interested in the field and has been privileged to be able to take courses and do research projects about that, I’m hearing a lot about ethics with algorithms, whether that’s fake news or bias or about applying algorithms for social good.

What are your biggest concerns about AI? What do you think needs to be addressed in order for us to feel more comfortable as a society with increased use of AI?

That’s not an easy answer; it’s something our society is going to be grappling with for years. From what I’ve learned at this conference, from what I’ve read and tried to understand, it’s a multidimensional solution. You’re going to need computer programmers to learn the technical skills to make their algorithms less biased. You’re going to need companies to hire those people and say, “This is our goal; we want to create an algorithm that’s fair and can do good.” You’re going to need the general society to ask for that standard. That’s my generation’s job, too. WikiLeaks, a couple of years ago, sparked the conversation about personal privacy and I think there’s going to be more sparks.
