FEED FEEDBACK

Sociologist Zeynep Tufekci engages with Adam Mosseri, who runs the Facebook News Feed

Tufekci: “…Facebook does not ask people what they want, in the moment or any other way. It sets up structures, incentives, metrics & runs with it.”

Mosseri: “We actually ask 10s of thousands of people a day how much they want to see specific stories in the News Feed, in addition to other things.”

Tufekci: “That’s not asking your users, that’s research on your product. Imagine a Facebook whose customers are users—you’d do so much differently. I mean asking all people, in deliberate fashion, with sensible defaults—there are always defaults—even giving them choices they can change…Think of the targeting offered to advertisers—with support to make them more effective—and flip the possibilities, with users as customers. The users are offered very little in comparison. The metrics are mostly momentary and implicit. That’s a recipe to play to impulse.”

The tweets are originally from Zeynep Tufekci in response to Benedict Evans (link), but the conversation is much easier to read in Hamza Shaban’s screenshots here.

See the end of this newsletter for an extended comment from Jay.

  • On looping effects (paywall): “This chapter argues that today's understanding of causal processes in human affairs relies crucially on concepts of ‘human kinds’ which are a product of the modern social sciences, with their concern for classification, quantification, and intervention. Child abuse, homosexuality, teenage pregnancy, and multiple personality are examples of such recently established human kinds. What distinguishes human kinds from ‘natural kinds’, is that they have specific ‘looping effects’. By coming into existence through social scientists' classifications, human kinds change the people thus classified.” Link. ht Jay

THE MESO-LEVEL

Mechanisms and causes between micro and macro

Daniel Little, the philosopher of social science behind Understanding Society, haswritten numerous posts on the topic. Begin with this one from 2014:

“It is fairly well accepted that there are social mechanisms underlying various patterns of the social world — free-rider problems, communications networks, etc. But the examples that come readily to mind are generally specified at the level of individuals. The new institutionalists, for example, describe numerous social mechanisms that explain social outcomes; but these mechanisms typically have to do with the actions that purposive individuals take within a given set of rules and incentives.

“The question here is whether we can also make sense of the notion of a mechanism that takes place at the social level. Are there meso-level social mechanisms? (As always, it is acknowledged that social stuff depends on the actions of the actors.)”

In the post, Little defines a causal mechanism and a meso-level mechanism, then offers example research.

“…It is possible to identify a raft of social explanations in sociology that represent causal assertions of social mechanisms linking one meso-level condition to another. Here are a few examples:

  • Al Young: decreasing social isolation causes rising inter-group hostility (link)
  • Michael Mann: the presence of paramilitary organizations makes fascist mobilization more likely (link)
  • Robert Sampson: features of neighborhoods influence crime rates (link)
  • Chuck Tilly: the availability of trust networks makes political mobilization more likely (link)
  • Robert Brenner: the divided sovereignty system of French feudalism impeded agricultural modernization (link)
  • Charles Perrow: legislative control of regulatory agencies causes poor enforcement performance (link)

PREDICTIVE JUSTICE

How to build justice into algorithmic actuarial tools

Key notions of fairness contradict each other—something of an Arrow’s Theorem for criminal justice applications of machine learning.

"Recent discussion in the public sphere about algorithmic classification has involved tension between competing notions of what it means for a probabilistic classification to be fair to different groups. We formalize three fairness conditions that lie at the heart of these debates, and we prove that except in highly constrained special cases, there is no method that can satisfy these three conditions simultaneously. Moreover, even satisfying all three conditions approximately requires that the data lie in an approximate version of one of the constrained special cases identified by our theorem. These results suggest some of the ways in which key notions of fairness are incompatible with each other, and hence provide a framework for thinking about the trade-offs between them."

Full paper from JON KLEINBERG, SENDHIL MULLAINATHAN and MANISH RAGHAVAN here. h/t research fellow Sara, who recently presented on bias in humans, courts, and machine learning algorithms, and who was the source for all the papers in this section.

In a Twitter thread, ARVIND NARAYANAN describes the issue in more casual terms.

"Today in Fairness in Machine Learning class: a comparison of 21 (!) definitions of bias and fairness [...] In CS we're used to the idea that to make progress on a research problem as a community, we should first all agree on a definition. So 21 definitions feels like a sign of failure. Perhaps most of them are trivial variants? Surely there/s one that's 'better' than the rest? The answer is no! Each defn (stat. parity, FPR balance, contextual fairness in RL...) captures something about our fairness intuitions."

Link to Narayanan’s thread.

Jay comments: Kleinberg et al. describe their result as choosing between conceptions of fairness. It’s not obvious, though, that this is the correct description. The criteria (calibration and balance) discussed aren’t really conceptions of fairness; rather, they’re (putative) tests of fairness. Particular questions about these tests aside, we might have a broader worry: if fairness is not an extensional property that depends upon, and only upon, the eventual judgments rendered by a predictive process, exclusive of the procedures that led to those judgments, then no extensional test will capture fairness, even if this notion is entirely unambiguous and determinate. It’s worth consideringNozick’s objection to “pattern theories” of justice for comparison, and (procedural) due process requirements in US law.

EXPLAINING ARTIFICIAL INTELLIGENCE | NEW METRICS

ARTIFICIAL AGENCY AND EXPLANATION

The gray box of XAI

A recent longform piece in the New York Times identifies the problem of explaining artificial intelligence. The stakes are high because of the European Union’s controversial and unclear “right-to-explanation” law, which will become active in May 2018.

“Instead of certainty and cause, A.I. works off probability and correlation. And yet A.I. must nonetheless conform to the society we’ve built — one in which decisions require explanations, whether in a court of law, in the way a business is run or in the advice our doctors give us. The disconnect between how we make decisions and how machines make them, and the fact that machines are making more and more decisions for us, has birthed a new push for transparency and a field of research called explainable A.I., or X.A.I. Its goal is to make machines able to account for the things they learn, in ways that we can understand. But that goal, of course, raises the fundamental question of whether the world a machine sees can be made to match our own.”

Full article by CLIFF KUANG here. This page provides a short overview of DARPA's XAI (Explainable Artificial Intelligence) program.

An interdisciplinary group addresses the problem:

"Contrary to popular wisdom of AI systems as indecipherable black boxes, we find that this level of explanation should often be technically feasible but may sometimes be practically onerous—there are certain aspects of explanation that may be simple for humans to provide but challenging for AI systems, and vice versa. As an interdisciplinary team of legal scholars, computer scientists, and cognitive scientists, we recommend that for the present, AI systems can and should be held to a similar standard of explanation as humans currently are; in the future we may wish to hold an AI to a different standard."

Full article by FINALE DOSHI-VELEZ et al. here. ht Margarita For the layperson, the most interesting part of the article may be its general overview of societal norms around explanation and explanation in the law.

Michael comments: Human cognitive systems have generated similar questions in vastly different contexts. The problem of chick-sexing (see Part 3) gave rise to a mini-literature within epistemology.

From Michael S. Moore’s book Law and Society: Rethinking the Relationship: “A full explanation in terms of reasons for action requires two premises: the major premise, specifying the agent’s desires (goals, objectives, moral beliefs, purposes, aims, wants, etc.), and the minor premise, specifying the agent’s factual beliefs about the situation he is in and his ability to achieve, through some particular action, the object of his desires.” Link. ht Margarita

Un Coup de dés

HIGHER EDUCATION | EXPLANATION, PART II

THE FUTURE OF UNDERGRADUATE EDUCATION

A new report argues that quality, not access, is the pivotal challenge for colleges and universities

From the American Academy of Arts and Sciences, a 112-page report with "practical and actionable recommendations to improve the undergraduate experience":

"Progress toward universal education has expanded most recently to colleges and universities. Today, almost 90 percent of high school graduates can expect to enroll in an undergraduate institution at some point during young adulthood and they are joined by millions of adults seeking to improve their lives. What was once a challenge of quantity in American undergraduate education, of enrolling as many students as possible, is now a challenge of quality—of making sure that all students receive the rigorous education they need to succeed, that they are able to complete the studies they begin, and that they can do this affordably, without mortgaging the very future they seek to improve."

Link to the full report. Co-authors include Gail Mellow, Sherry Lansing, Mitch Daniels, and Shirley Tilghman. ht Will, who highlights a few of the report's recommendations that stand out:

  • From page 40: "Both public and private colleges and universities as well as state policy-makers [should] work collaboratively to align learning programs and expectations across institutions and sectors, including implementing a transferable general education core, defined transfer pathway maps within popular disciplines, and transfer-focused advising systems that help students anticipate what it will take for them to transfer without losing momentum in their chosen field."
  • From page 65: "Many students, whether coming straight out of high school or adults returning later to college, face multiple social and personal challenges that can range from homelessness and food insecurity to childcare, psychological challenges, and even imprisonment. The best solutions can often emerge from building cooperation between a college and relevant social support agencies.
  • From page 72: "Experiment with and carefully assess alternatives for students to manage the financing of their college education. For example, income-share agreements allow college students to borrow from colleges or investors, which then receive a percentage of the student’s after-graduation income."
  • On a related note, see this 2016 paper from the Miller Center at the University of Virginia: "Although interest in the ISA as a concept has ebbed and flowed since Milton Friedman first proposed it in the 1950s, today it is experiencing a renaissance of sorts as new private sector partners and institutions look to make the ISA a feasible option for students. ISAs offer a novel way to inject private capital into higher education systems while striking a balance between consumer preferences and state needs for economic skill sets. The different ways ISAs can be structured make them highly suitable as potential solutions for many states’ education system financing problems." Link.
  • Meanwhile, Congress is working on the reauthorization of the Higher Education Act: "Much of the proposal that House Republicans released last week is controversial and likely won’t make it into the final law, but the plan provides an indication of Congressional Republicans’ priorities for the nation’s higher education system. Those priorities include limiting the federal government’s role in regulating colleges, capping graduate student borrowing, making it easier for schools to limit undergraduate borrowing — and overhauling the student loan repayment system. Many of those moves have the potential to create a larger role for private industry." Link.

CONTENT MODERATION | CARBON CAPTURE AND STORAGE | RURAL POLICIES

HOW TO HANDLE BAD CONTENT

Two articles illustrate the state of thought on moderating user-generated content

Ben Thompson of Stratechery rounds up recent news on content moderation on Twitter/Facebook/Youtube and makes a recommendation:

“Taking political sides always sounds good to those who presume the platforms will adopt positions consistent with their own views; it turns out, though, that while most of us may agree that child exploitation is wrong, a great many other questions are unsettled.

“That is why I think the line is clearer than it might otherwise appear: these platform companies should actively seek out and remove content that is widely considered objectionable, and they should take a strict hands-off policy to everything that isn’t (while — and I’m looking at you, Twitter — making it much easier to avoid unwanted abuse from people you don’t want to hear from). Moreover, this approach should be accompanied by far more transparency than currently exists: YouTube, Facebook, and Twitter should make explicitly clear what sort of content they are actively policing, and what they are not; I know this is complicated, and policies will change, but that is fine — those changes can be transparent too.”

Full blog post here.

The Social Capital newsletter responds:

“… If we want to really make progress towards solving these issues we need to recognize there’s not one single type of bad behavior that the internet has empowered, but rather a few dimensions of them.”

The piece goes on to describe four types of bad content. Link.

Michael comments: The discussion of content moderation--and digital curation more broadly--conspicuously ignores the possibility of algorithmic methods for analyzing and disseminating (ethically or evidentiarily) valid information. Thompson and Social Capital default to traditional and cumbersome forms of outright censorship, rather than methods to “push” better content.

We'll be sharing more thoughts on this research area in future letters.

The Year in Review

INCOME SHARE AGREEMENTS Purdue, BFF, the national conversation “Long discussed in college policy and financing circles, income share agreements, or ISAs, are poised to become more mainstream.” That's from a September Wall Street Journal article. 2017 saw new pilots and the introduction of legislation in Congress, as well as the continued growth of Purdue’s Back a Boiler program, which was covered in PBS Newshour with JFI staff featured. Better Future Forward (incubated by JFI) was founded to originate ISAs and structure ISA pilots. Launched in February 2017 with support from the Arnold Foundation and the Lumina Foundation, BFF has formed partnerships with (and funded students through) Opportunity@Work, College Possible, and the Thurgood Marshall College Fund. Various research organizations are tracking ISAs closely: From the American Academy of Arts and Sciences, a 112-page report with "practical and actionable recommendations to improve the undergraduate experience": “What was once a challenge of quantity in American undergraduate education, of enrolling as many students as possible, is now a challenge of quality—of making sure that all students receive the rigorous education they need to succeed, that they are able to complete the studies they begin, and that they can do this affordably, without mortgaging the very future they seek to improve."

MINIMUM WAGE INCREASES | CONTRACTORS | FILTER BUBBLES

THE WAGE EFFECT

Higher minimum wages and the EITC may reduce recidivism

“Using administrative prison release records from nearly six million offenders released between 2000 and 2014, we use a difference-in-differences strategy to identify the effect of over two hundred state and federal minimum wage increases, as well as 21 state EITC programs, on recidivism. We find that the average minimum wage increase of 8% reduces the probability that men and women return to prison within 1 year by 2%. This implies that on average the wage effect, drawing at least some ex-offenders into the legal labor market, dominates any reduced employment in this population due to the minimum wage.”

Full paper by AMANDA Y. AGAN and MICHAEL D. MAKOWSKY here.

  • Jennifer Doleac responds, “The results in this new paper…definitely surprised me—my prior was that raising the min wage would increase recidivism.” She explains: “Those coming out of prison are very likely to be on the margin of employment (last hired, first fired). Given some disemployment effects, marginal workers are the ones who are going to be hurt. Amanda and Mike find that the positive effects of pulling some (higher-skilled?) offenders into the legal labor market outweigh those negative effects.” Link to Doleac’s Twitter thread.
  • One of the co-authors, Makowsky, adds, “The EITC, dollar for household dollar, generates larger effects [than minimum wage increases], but is hampered by its contingency on dependent children. This is one more reason to remove the contingency, extending it to everyone.” Link to Makowsky’s Twitter thread.
  • Another piece sourced from Makowsky’s thread: “The Impact of Living-Wage Ordinances on Urban Crime.” “Using data on annual crime rates for large cities in the United States, we find that living-wage ordinances are associated with notable reductions in property-related crime and no discernable impact on nonproperty crimes.” Link.
  • Noah Smith rounds up recent studies on increasing the minimum wage, many of which come to contradictory conclusions. "At this point, anyone following the research debate will be tempted to throw up their hands. What can we learn from a bunch of contradictory studies, each with its own potential weaknesses and flaws?" Link.

CONSEQUENCES OF BANNING THE BOX | ALGORITHMS FOR CHILD PROTECTION | SOVEREIGN WEALTH FUNDS

PERVERSE CONSEQUENCES

Does banning the box increase hiring discrimination?

“Our results support the concern that BTB [Ban the Box] policies encourage racial discrimination: the black-white gap in callbacks grew dramatically at companies that removed the box after the policy went into effect. Before BTB, white applicants to employers with the box received 7% more callbacks than similar black applicants, but BTB increased this gap to 43%. We believe that the best interpretation of these results is that employers are relying on exaggerated impressions of real-world racial differences in felony conviction rates.”

Newly published by AMANDA AGAN and SONJA STARR, in line with their previous work on the same topic, available here.

  • These results bolster longstanding concerns about perverse consequences arising from ban the box legislation. (Similar studies include this one from 2006, and this one from 2016.) A 2008 paper provides a theoretical accompaniment to these worries, arguing that a privacy tradeoff is required to ensure race is not being used as a proxy for criminal history: “By increasing the availability of information about individuals, we can reduce decisionmakers’ reliance on information about groups.… reducing privacy protections will reduce the prevalence of statistical discrimination.” Link.
  • In a three part series from 2016, Noah Zatz at On Labor took on the perverse consequences argument and its policy implications, levelling three broad criticisms: “it places blame in the wrong place, it relies upon the wrong definition of racial equality, and it ignores cumulative effects.” Linkto part one.
  • A 2017 study of ban the box that focussed on the public sector—where anti-discrimination enforcement is more robust—found an increase in the probability of hiring for individuals with convictions and “no evidence of statistical discrimination against young low-skilled minority males.” Link.
  • California’s Fair Chance Act went into effect January 1, 2018, joining a growing list of fair hiring regulations in many other states and counties by extending ban the box reforms to the private sector. The law provides that employers can only conduct criminal background checks after a conditional offer of employment has been made. More on the bill can be found here.
  • Two posts on the California case, again by Zatz at On Labor, discuss several rich policy design questions raised by the “bright line” standards included in this legislation, and how they may interact with the prima facie standard of disparate impact discrimination: “Advocates fear, however, that bright lines would validate the exclusion of people on the wrong side of the line, despite individualized circumstances that vindicate them. But of course, the opposite could also be the case.” Link.
  • Tangentially related, Ben Casselman reports in the New York Times that a tightening labor market may be encouraging some employers to hire beyond the box—without legislative guidance. Link.

Considerations on funding UBI in Britain

The RSA (Royal Society for the encouragement of Arts, Manufactures and Commerce) published a discussion paper on UBI. ANTHONY PAINTER outlines some key points here, including some thoughts on funding:

“To fund the ‘Universal Basic Opportunity Fund’ (UBOF), the Government would finance an endowment to cover the fund for 14 years from a public debt issue (at current low interest rates). This endowment would be invested to both fund asset growth and public benefit. The fund could be invested in housing, transport, energy and digital infrastructure and invested for high growth in global assets such as equity and real estate. This seems radical but actually, similar mechanisms have been established in Norway, Singapore and Alaska. In the latter case, Basic Income style dividends are paid to all Alaskans. Essentially, the UBOF is a low-interest mortgage to invest in infrastructure and human growth that brings forward the benefits of a sovereign wealth fund to the present rather than waiting for it to accumulate over time.”

Regional parochialism and the production of knowledge in universities

"Scholarly understanding of how universities transform money and intellect into knowledge remains limited. At present we have only rudimentary measures of knowledge production's inputs: tuition and fees, government subsidies, philanthropic gifts, and the academic credentials of students and faculty. Output measures are equally coarse: counts of degrees conferred; dissertations, articles and books completed; patents secured; dollars returned on particular inventions. As for the black box of knowledge production in between: very little."

From the introduction to a new book on American social science research that aims to uncover the institutional pathways that produce (and favor) certain areas of research.

It continues:

"The rise of 'global' discourse in the US academy has coevolved with fundamental changes in academic patronage, university prestige systems, and the international political economy. America's great research institutions are now only partly servants of the US nation-state. This fact has very large implications for those who make their careers producing scholarly knowledge."

Link to the introduction.

  • A short interview with co-authors Mitchell L. Stevens and Cynthia Miller-Idris. "Sociology department chairs said frankly that they deliberately steer graduate students away from international study because such projects on non-U.S. topics are less likely to have purchase on the tenure-line job market.… The tenure process is largely mediated by disciplines, and because those disciplines prioritize their own theoretical abstractions, contextual knowledge loses out."
