Aleksandr Kogan: The psychologist at the centre of Facebook's data scandal

(BLOOMBERG) - In a video published online in September, a social scientist named Alex Spectre made an earnest pitch for his new startup.

Clad in the Silicon Valley uniform of open-collar shirt and blazer, Spectre boasted that his company - Philometrics - would revolutionise the way online surveys were done, making it easier for companies to design questionnaires that people would actually respond to on Facebook, Twitter or other sites.

Crucially, he said, the surveys could predict the responses for large groups from a small number of respondents and micro-target ads better.

"The reality is working with big data, social media is incredibly difficult," said Spectre, who more commonly goes by Aleksandr Kogan, which he uses in his role as a Cambridge University researcher.

"You want to work with people who have a lot of experience. You want to connect with people who have been working with these massive data sets."

Kogan would know. On Friday (March 16), he was suspended by Facebook Inc. for his earlier work mining data on what the New York Times reported was as many as 50 million Facebook users and sharing it with Cambridge Analytica, a political-advertising firm that helped Donald Trump win the 2016 US presidential election.

Facebook suspended Kogan over allegations that he lied when he said the data would be used for research purposes only. The social network suspended Cambridge Analytica as well.

The boyish-appearing Kogan has been thrown into the centre of a scandal that has called into question not only the methods the Trump campaign used to psychoanalyze and target potential voters and win the presidency, but also the practices of Silicon Valley companies in allowing third parties to access and exploit private information.

Facebook has since disabled the feature that let Kogan amass personal data on millions of users when less than 1 percent of those people even downloaded his app.

But the episode offers a glimpse into how promiscuous some internet giants actually are with information that many users assume is always kept secret.

Government officials in the US and Europe are calling for Facebook Chief Executive Officer Mark Zuckerberg to appear in front of lawmakers, and the demands for answers may foreshadow tougher regulation for the social network.

Kogan didn't respond to multiple attempts to reach him for comment.

His ill-fated detour from the academic track into the darker corners of social media marketing began in 2014 when UK-based Cambridge Analytica turned to Kogan for help. The firm was interested in a data project Kogan had worked on at Cambridge University that was based on research into personality traits and social media.

Kogan, who had moved to the US from Russia as a child and graduated from the University of California at Berkeley in 2008 with a degree in psychology before moving to Hong Kong for his doctorate, ultimately joined Cambridge University in 2012, where he remains a research associate in the psychology department, a position he has retained since relocating back to the San Francisco Bay area.

While at Cambridge University, Kogan formed a company in the UK called Global Science Research, which created an app called 'thisisyourdigitallife' that offered Facebook users personality predictions, in exchange for accessing their personal data on the social network and more limited information about their friends - including their "likes" - if their privacy settings allowed it.

Only about 270,000 people downloaded the app, but the researchers were able to mine the profiles of tens of millions of people through tools Facebook had at the time that gave third parties access to a wide swath of information.

Kogan's company then took the results of those personality surveys and matched them to the users' actual likes on Facebook - and the likes of their friends - to build a model predicting personalities based on digital behavior. The company eventually gave Cambridge Analytica a list of millions of people in the US, with their names, locations, genders, ages and predicted test scores.

In his 2017 video promoting Philometrics, Kogan touted his team's unique expertise in cracking this code, of predicting the tastes of a large group of people from the responses of a smaller one, which he described as one of the central challenges of doing online research or targeted marketing.

"Social media data is incredible in its opportunities, but it's also incredibly challenging," Kogan said in the video.

Until 2014, Facebook's rules let third parties access this back-door channel to friends' data. That year, the company tightened its privacy settings to "ensure that each person decides what information they want to share about themselves, including their friend list."

Facebook has worked to counter the description of what happened as a "breach," but the reality is that the underlying act of data scraping by third parties was not only permitted but encouraged by the social network - raising questions about how many others abused their access to Facebook user information.

For its part, Cambridge Analytica said the Facebook data wasn't used as part of the services it provided to Trump's presidential campaign, adding that it fully complies with Facebook's terms of service and is working with the company to resolve the matter.

A person familiar with Kogan's company's work last year told Bloomberg News that the methodology and data that it gave to Cambridge Analytica was almost useless in predicting individual personalities, because of a high error rate, and that Cambridge Analytica's claim of being able to provide behavioral micro-targeting of ads down to the individual level is more marketing bluster than Big Brother.

The more difficult issue for Facebook is that it had been aware of the controversy over Kogan and Cambridge Analytica's use of the information since 2015, when Facebook demanded he and Cambridge Analytica delete the data.

The social network is now dealing with the fallout of being unable to police how collectors of private Facebook data during that time used the information, and whether they followed Facebook's rules about sharing or selling it. Facebook is also investigating whether one of its employees, Joseph Chancellor, who formed Global Science Research with Kogan while Chancellor was a doctoral student at Cambridge University, knew about the data leak. Chancellor is now a social-psychology researcher at Facebook. He didn't respond to a message via LinkedIn seeking comment.

Cambridge University said in a statement that it had no evidence to suggest that Kogan had used university resources or facilities for the Global Science Research work, but that it has contacted Facebook requesting "all relevant evidence in their possession."

The University said that Kogan had sought permission from the head of the psychology department to work with St. Petersburg University on the condition that any grants he received would be "in a private capacity, separate to his work at University of Cambridge."

A person familiar with Kogan's work says he had a grant that allowed him to do minimal teaching in 2017 and 2018, without specifying the source or nature of the award.

In 2015, Kogan and his new wife decided to change their last name to something that reflected their belief in both religion and science, and they settled on Spectre, six months before the James Bond film of the same name came out, and long before Russian election meddling dominated the news.

A person close to Kogan said the name change had nothing to do with the controversy surrounding his work.

"What person would change their name to a Bond villain," the person said, "to avoid bad press?"
