How Cambridge Analytica’s Facebook targeting model really worked – according to the person who built it

How Cambridge Analytica’s Facebook targeting model really worked – according to the person who built it

How accurately can you be profiled online? Andrew Krasovitckii/Shutterstock.com By Matthew Hindman, George Washington University The researcher whose work is at the center of the Facebook-Cambridge Analytica data analysis and political advertising uproar has revealed that his method worked much like the one Netflix uses to recommend movies. In an email to me, Cambridge University scholar Aleksandr Kogan explained how his statistical model processed Facebook data for Cambridge Analytica. The accuracy he claims suggests it works about as well as…

Did the U.S. miss its chance to stop North Korea’s nuclear programme?

Did the U.S. miss its chance to stop North Korea’s nuclear programme?

Julian Borger writes: Pyongyang International is one of the world’s quieter airports. The country’s chronic isolation means that there are not many places to fly, and few foreigners keen on visiting. At least until a new terminal was built in 2012, many of the flights on the departure boards were just for show, giving the appearance of connection with the outside world. They never actually took off. Against this melancholy backdrop, one day in late May 1999, something quite extraordinary…

The Bosworth memo: The ugly truth about Facebook’s addiction to growth

The Bosworth memo: The ugly truth about Facebook’s addiction to growth

BuzzFeed reports: On June 18, 2016, one of Facebook CEO Mark Zuckerberg’s most trusted lieutenants circulated an extraordinary memo weighing the costs of the company’s relentless quest for growth. “We connect people. Period. That’s why all the work we do in growth is justified. All the questionable contact importing practices. All the subtle language that helps people stay searchable by friends. All of the work we do to bring more communication in. The work we will likely have to do…

Can social media be saved?

Can social media be saved?

Kevin Roose writes: I don’t need to tell you that something is wrong with social media. You’ve probably experienced it yourself. Maybe it’s the way you feel while scrolling through your Twitter feed — anxious, twitchy, a little world weary — or your unease when you see a child watching YouTube videos, knowing she’s just a few algorithmic nudges away from a rabbit hole filled with lunatic conspiracies and gore. Or maybe it was this month’s Facebook privacy scandal, which…

The policing of opinion has become established practice in societies that call themselves free

The policing of opinion has become established practice in societies that call themselves free

John Gray writes: For liberals the recent transformation of universities into institutions devoted to the eradication of thought crime must seem paradoxical. In the past higher education was avowedly shaped by an ideal of unfettered inquiry. Varieties of social democrats and conservatives, liberals and Marxists taught and researched alongside scholars with no strong political views. Academic disciplines cherished their orthodoxies, and dissenters could face difficulties in being heard. But visiting lecturers were rarely dis­invited because their views were deemed unspeakable,…

John Bolton to Kim Jong Un: Give up your nukes like Gaddafi did — before we killed him

John Bolton to Kim Jong Un: Give up your nukes like Gaddafi did — before we killed him

Jeffrey Lewis writes: So, President Trump’s has tapped John Bolton to be his next national security adviser. Most readers will be familiar with the broad outlines of the Bolton story—he is famously awful as a boss and his hawkish tendencies border on the absurd. A Republican Senate refused to confirm his nomination, by George W. Bush, as ambassador to the United Nations. The thought of Bolton in New York literally moved Sen. George Voinovich, a Republican, to tears. Bolton has,…

Why did Kim Jong Un just visit China?

Why did Kim Jong Un just visit China?

Ankit Panda writes: For months, China seemed to be a side player as relations improved between North Korea and South Korea. Kim Jong Un, the leader of North Korea, kicked off the year with an address celebrating the completion of his nuclear deterrent after months of boasting about his increasing nuclear capability. In his speech, he also expressed interest in North Korea’s participation in the Winter Olympics. That, in turn, provided Moon Jae In, the president of South Korea, with…

The deeply underdeveloped worldview of John Bolton

The deeply underdeveloped worldview of John Bolton

Peter Beinart writes: Survey the history of American national-security advisors going back to the position’s creation in the mid-twentieth century, and two things about John Bolton stand out. The first is his militancy: his incessant, almost casual, advocacy of war. The second—which has gotten less attention but is deeply intertwined with the first—is the parochialism of his life experience. Many national-security advisors, including Robert McFarlane, John Poindexter, Colin Powell, James Jones, Michael Flynn, and H.R. McMaster, have come from the…

FBI looked into Trump plans to build hotel in Latvia with Putin supporter

The Guardian reports: They wanted to build the Las Vegas of the Baltics. In 2010, a small group of businessmen including a wealthy Russian supporter of Vladimir Putin began working on plans to build a glitzy hotel and entertainment complex with Donald Trump in Riga, the capital of Latvia.

How Trump is rigging the census

How Trump is rigging the census

Mother Jones reports: The census is America’s largest civic event, the only one that involves everyone in the country, young and old, citizen and noncitizen, rich and poor—or at least it’s supposed to. It’s been conducted every 10 years since 1790, when US Marshals first swore an oath to undertake “a just and perfect enumeration” of the population. The census determines how $675 billion in federal funding is allocated to states and localities each year for things like health care,…

The unwelcome revival of ‘race science’

The unwelcome revival of ‘race science’

Gavin Evans writes: One of the strangest ironies of our time is that a body of thoroughly debunked “science” is being revived by people who claim to be defending truth against a rising tide of ignorance. The idea that certain races are inherently more intelligent than others is being trumpeted by a small group of anthropologists, IQ researchers, psychologists and pundits who portray themselves as noble dissidents, standing up for inconvenient facts. Through a surprising mix of fringe and mainstream…

‘Dead zone’ in Gulf of Mexico will take decades to recover from farm pollution

‘Dead zone’ in Gulf of Mexico will take decades to recover from farm pollution

The Guardian reports: The enormous “dead zone” in the Gulf of Mexico will take decades to recover even if the flow of farming chemicals that is causing the damage is completely halted, new research has warned. Intensive agriculture near the Mississippi has led to fertilizers leeching into the river, and ultimately the Gulf of Mexico, via soils and waterways. This has resulted in a huge oxygen-deprived dead zone in the Gulf that is now at its largest ever extent, covering…

Christopher Steele’s other report: A murder in Washington

BuzzFeed reports: The FBI possesses a secret report asserting that Vladimir Putin’s former media czar was beaten to death by hired thugs in Washington, DC — directly contradicting the US government’s official finding that Mikhail Lesin died by accident. The report, according to four sources who have read all or parts of it, was written by the former British intelligence agent Christopher Steele, who also wrote the famous dossier alleging that Russia had been “cultivating, supporting and assisting” Donald Trump….

Palantir employee helped Cambridge Analytica before it harvested data

Palantir employee helped Cambridge Analytica before it harvested data

The New York Times reports: As a start-up called Cambridge Analytica sought to harvest the Facebook data of tens of millions of Americans in summer 2014, the company received help from at least one employee at Palantir Technologies, a top Silicon Valley contractor to American spy agencies and the Pentagon. It was a Palantir employee in London, working closely with the data scientists building Cambridge’s psychological profiling technology, who suggested the scientists create their own app — a mobile-phone-based personality…

Attack on Atlanta one of the most sustained and consequential cyberattacks ever mounted against a major American city

The New York Times reports: The City of Atlanta’s 8,000 employees got the word on Tuesday that they had been waiting for: It was O.K. to turn their computers on. But as the city government’s desktops, hard drives and printers flickered back to life for the first time in five days, residents still could not pay their traffic tickets or water bills online, or report potholes or graffiti on a city website. Travelers at the world’s busiest airport still could…
