Introduction by Jay Tolson to a Special Issue of HedgeHog Review: “At a time when distraction and mendacity degrade public discourse, the heartbreaking toll of the current pandemic should at least remind us that quantification—data, numbers, statistics—are vitally important to policy, governance, and decision-making more broadly. Confounding as they may be to some of us, numbers are arguably humankind’s most useful technology—our greatest discovery, or possibly our greatest invention. But the current global crisis should also remind us of something equally important: Good numbers, like good science, can only do so much to inform wise decisions about our personal... (More >)
Race and America: why data matters
Federica Cocco and Alan Smith at the Financial Times: “… To understand the historical roots of black data activism, we have to return to October 1899. Back then, Thomas Calloway, a clerk in the War Department, wrote to the educator Booker T Washington about his pitch for an “American Negro Exhibit” at the 1900 Exposition Universelle in Paris. It was right in the middle of the scramble for Africa and Europeans had developed a morbid fascination with the people they were trying to subjugate. To Calloway, the Paris exhibition offered a unique venue to sway the global elite to... (More >)
Why Hundreds of Mathematicians Are Boycotting Predictive Policing
Courtney Linder at Popular Mechanics: “Several prominent academic mathematicians want to sever ties with police departments across the U.S., according to a letter submitted to Notices of the American Mathematical Society on June 15. The letter arrived weeks after widespread protests against police brutality, and has inspired over 1,500 other researchers to join the boycott. These mathematicians are urging fellow researchers to stop all work related to predictive policing software, which broadly includes any data analytics tools that use historical data to help forecast future crime, potential offenders, and victims. The technology is supposed to use probability to help... (More >)
Why real-time economic data need to be treated with caution
The Economist: “The global downturn of 2020 is probably the most quantified on record. Economists, firms and statisticians seeking to gauge the depth of the collapse in economic activity and the pace of the recovery have seized upon a new dashboard of previously obscure indicators. Investors eagerly await the release of mobility statistics from tech companies such as Apple or Google, or restaurant-booking data from OpenTable, in a manner once reserved for official inflation and unemployment estimates. Central bankers pepper their speeches with novel barometers of consumer spending. Investment-bank analysts and journalists tout hot new measures of economic activity... (More >)
German coronavirus experiment enlists help of concertgoers
Philip Oltermann at the Guardian: “German scientists are planning to equip 4,000 pop music fans with tracking gadgets and bottles of fluorescent disinfectant to get a clearer picture of how Covid-19 could be prevented from spreading at large indoor concerts. As cultural mass gatherings across the world remain on hold for the foreseeable future, researchers in eastern Germany are recruiting volunteers for a “coronavirus experiment” with the singer-songwriter Tim Bendzko, to be held at an indoor stadium in the city of Leipzig on 22 August. Participants, aged between 18 and 50, will wear matchstick-sized “contact tracer” devices on chains... (More >)
Coronavirus: how the pandemic has exposed AI’s limitations
Kathy Peach at The Conversation: “It should have been artificial intelligence’s moment in the sun. With billions of dollars of investment in recent years, AI has been touted as a solution to every conceivable problem. So when the COVID-19 pandemic arrived, a multitude of AI models were immediately put to work. Some hunted for new compounds that could be used to develop a vaccine, or attempted to improve diagnosis. Some tracked the evolution of the disease, or generated predictions for patient outcomes. Some modelled the number of cases expected given different policy choices, or tracked similarities and differences between... (More >)
A Letter on Justice and Open Debate
Letter in Harpers Magazine signed by 153 prominent artists and intellectuals,: “Our cultural institutions are facing a moment of trial. Powerful protests for racial and social justice are leading to overdue demands for police reform, along with wider calls for greater equality and inclusion across our society, not least in higher education, journalism, philanthropy, and the arts. But this needed reckoning has also intensified a new set of moral attitudes and political commitments that tend to weaken our norms of open debate and toleration of differences in favor of ideological conformity. As we applaud the first development, we also... (More >)
How urban design can make or break protests
Peter Schwartzstein in Smithsonian Magazine: “If protesters could plan a perfect stage to voice their grievances, it might look a lot like Athens, Greece. Its broad, yet not overly long, central boulevards are almost tailor-made for parading. Its large parliament-facing square, Syntagma, forms a natural focal point for marchers. With a warren of narrow streets surrounding the center, including the rebellious district of Exarcheia, it’s often remarkably easy for demonstrators to steal away if the going gets rough. Los Angeles, by contrast, is a disaster for protesters. It has no wholly recognizable center, few walkable distances, and little in... (More >)
The Shape of Epidemics
Essay by David S. Jones and Stefan Helmreich: “…Is the most recent rise in new cases—the sharp increase in case counts and hospitalizations reported this week in several states—a second wave, or rather a second peak of a first wave? Will the world see a devastating second wave in the fall? Such imagery of waves has pervaded talk about the propagation of the infection from the beginning. On January 29, just under a month after the first instances of COVID-19 were reported in Wuhan, Chinese health officials published a clinical report about their first 425 cases, describing them as...

Politicians ignore far-out risks: they need to up their game
The Economist: “In 1993 this newspaper told the world to watch the skies. At the time, humanity’s knowledge of asteroids that might hit the Earth was woefully inadequate. Like nuclear wars and large volcanic eruptions, the impacts of large asteroids can knock seven bells out of the climate; if one thereby devastated a few years’ worth of harvests around the globe it would kill an appreciable fraction of the population. Such an eventuality was admittedly highly unlikely. But given the consequences, it made actuarial sense to see if any impact was on the cards, and at the time no... (More >)
