 The Facebook-Cambridge Analytica Scandal: What Happened?

How Did Cambridge Analytica Collect Facebook Data?

In 2014, a British data analytics firm, Cambridge Analytica, secretly harvested personal data from millions of Facebook users without their consent. The data collection was enabled by:

🔹 A Facebook quiz app ("This Is Your Digital Life") created by researcher Aleksandr Kogan.

🔹 The app collected detailed personality traits, interests, and social connections of users.

🔹 Only 270,000 people took the quiz, but due to Facebook’s lax data-sharing policies, the app could access data from friends of those users, leading to massive data harvesting.

How Was the Data Used?

Cambridge Analytica processed and analyzed the stolen data to:

✅ Create psychographic profiles of millions of voters.

✅ Identify persuadable individuals in swing states.

✅ Target users with highly personalized political ads to influence their voting behavior.

This strategy helped shape key political events, including:

  • The 2016 Trump Campaign → Used targeted Facebook ads based on voter personalities.
  • Brexit Referendum (2016) → Influenced public sentiment toward leaving the EU.

 The Role of Big Data in Political Manipulation

How Can Big Data Influence Elections?

Big data allows political campaigns to:

📌 Segment voters based on demographics, behavior, and psychology.

📌 Deliver customized political messages to influence decisions.

📌 Spread misinformation and emotional triggers to sway public opinion.

Cambridge Analytica’s Psychological Targeting

Cambridge Analytica used psychographic profiling to classify voters into:

  • "Openness" voters (More liberal, targeted with progressive messaging).
  • "Conscientiousness" voters (More conservative, targeted with nationalist messaging).
  • "Agreeableness" voters (Undecided, bombarded with fear-based political ads).

By leveraging big data and AI-powered microtargeting, political campaigns manipulated voter behavior at an unprecedented scale.
