What state should you move to based on your personality? What character on “Downton Abbey” would you be? What breed of dog is best for you? Some enormous percentage of Facebook’s 2.13 billion users must have seen Facebook friends sharing results of various online quizzes.
They are sometimes annoying, senseless and a total waste of time. But they are irresistible. Besides, you’re only sharing the results with your family and friends. There’s nothing more innocent, right?Wrong.
Facebook is in the business of exploiting your data. The company is worth billions of dollars because it harvests your data and sells it to advertisers. Users are encouraged to like, share and comment their lives away in the name of staying connected to family and friends. However, as an ethical hacker, security researcher and data analyst, I know that there is a lot more to the story. The bedrock of modern democracy is at stake.
You are being psychographically profiled
Most people have heard of demographics – the term used by advertisers to slice up a market by age, gender, ethnicity and other variables to help them understand customers. In contrast, psychographics measure people’s personality, values, opinions, attitudes, interests and lifestyles. They help advertisers understand the way you act and who you are.
Historically, psychographic data were much harder to collect and act on than demographics. Today, Facebook is the world’s largest treasure trove of this data. Every day billions of people give the company huge amounts of information about their lives and dreams.
This isn’t a problem when the data are used ethically – like when a company shows you an ad for a pair of sunglasses you recently searched for.
However, it matters a lot when the data are used maliciously – segmenting society into disconnected echo chambers, and custom-crafting misleading messages to manipulate individuals’ opinions and actions.
That’s exactly what Facebook allowed to happen.
Quizzes, reading your mind and predicting your politics
Recent reports have revealed how Cambridge Analytica, a U.K.-based company owned by an enigmatic billionaire and led at the time by candidate Donald Trump’s key adviser Steve Bannon, used psychographic data from Facebook to profile American voters in the months before the 2016 presidential election. Why? To target them with personalized political messages and influence their voting behavior.
A whistleblower from Cambridge Analytica, Christopher Wylie, described in detail how the company exploited Facebook users by harvesting their data and building models to “target their inner demons.”
How did Facebook let this happen?
The company does more than just sell your data. Since the early 2000s, Facebook has provided access to academic researchers seeking to study you. Many psychologists and social scientists have made their careers analyzing ways to predict your personality and ideologies by asking simple questions. These questions, like the ones used in social media quizzes, do not appear to have obvious connections to politics. Even a decision like which web browser you are using to read this article is filled with clues about your personality.
In 2015, Facebook gave permission to academic researcher Aleksandr Kogan to develop a quiz of his own. Like other quizzes, his was able to capture all of your public information, including name, profile picture, age, gender and birthday; everything you’ve ever posted on your timeline; your entire friends list; all of your photos and the…
