# Cambridge Analytica Scandal (March 2018) The revelation that a military-intelligence-linked data firm, funded by the Mercer family and run by [[Steve Bannon]], harvested the personal data of 87 million Facebook users to build psychographic voter targeting tools for the 2016 Trump campaign. ## The Data Harvesting In 2013, Cambridge University researcher [[Aleksandr Kogan]] created a personality quiz app called "This Is Your Digital Life." Approximately 270,000 users installed the app — but due to Facebook's permissive API policies at the time, the app also harvested personal data (likes, interests, location, friend networks) from those users' entire friend lists. The resulting dataset covered roughly 87 million people. Kogan then sold this data to [[Cambridge Analytica]], in violation of Facebook's terms of service. ## The Company Cambridge Analytica was a subsidiary of **SCL Group** (Strategic Communication Laboratories), a British firm founded in the 1990s that specialized in psychological operations for militaries and intelligence agencies. SCL had worked with the British Army's 15 Psychological Operations Group, the Norwegian Defense Research Agency, and US defense contractors. This military-psyops pedigree was the foundation for Cambridge Analytica's voter profiling techniques. **Ownership**: [[Robert Mercer]] provided $15 million in founding capital. The company was approximately 90% Mercer-owned, 10% SCL-owned. **Leadership**: [[Steve Bannon]] served as vice president and secretary, overseeing early data collection strategy, until August 2016 when he left to manage Trump's presidential campaign. [[Rebekah Mercer]] served on the board. ## Political Deployment Cambridge Analytica received $5.9 million from the Trump 2016 campaign to build psychographic profiles and deliver micro-targeted digital messaging. The firm categorized voters by personality type and designed custom ad content to exploit psychological vulnerabilities. Internal documents showed that 3.5 million African American voters were categorized under "deterrence" targeting — i.e., efforts to suppress their turnout rather than persuade them. The firm also worked with Leave.EU during the Brexit campaign, though the UK Information Commissioner's Office later concluded Cambridge Analytica was "not directly involved" in the referendum itself. ## The Whistleblower [[Christopher Wylie]], a former Cambridge Analytica employee, provided documents to *The Guardian* and *The New York Times* in March 2018, exposing the data harvesting operation. His testimony before UK Parliament (March 2018) and the US Senate (May 2018) triggered government investigations worldwide. *Time* named Wylie one of its 100 Most Influential People of 2018. ## Facebook's Reckoning [[Mark Zuckerberg]] testified before Congress on April 10-11, 2018, acknowledging Facebook's failure to prevent misuse and calling it a "breach of trust." Facebook had known about the data harvesting since 2015 and had requested that Cambridge Analytica delete the data, but never verified that deletion occurred. **Outcome**: Facebook paid a $5 billion FTC fine in July 2019 — the largest privacy-related penalty in history at that time. Cambridge Analytica filed for Chapter 7 bankruptcy in May 2018. ## Significance Cambridge Analytica demonstrated how the right-wing donor class could operationalize data as a political weapon. The Mercer-Bannon axis didn't just fund campaigns — they built a military-grade persuasion operation and pointed it at the American electorate. The scandal also revealed Facebook's structural inability (or unwillingness) to prevent its platform from being weaponized, a pattern that would repeat through 2020 election disinformation and beyond. ## See Also - [[Robert Mercer]] - [[Rebekah Mercer]] - [[Steve Bannon]] - [[Mark Zuckerberg]] - [[Pentagon Influence Operations - gc_ Generation]] — The Pentagon's gc\_ generation adopted the same core insight Cambridge Analytica pioneered: paid platform advertising as influence technology.
