Cambridge Analytica Facebook

Scope

The initial governed demo scope is primarily:

The dossier does not assume Cambridge Analytica caused Donald Trump's victory, caused Brexit, or possessed a uniquely effective "mind-control" technology.

• data acquisition / deception / platform-policy conduct, and
• whether Cambridge Analytica's work measurably changed an election outcome.
• U.S. Facebook data / U.S. voter profiling,
• 2016 U.S. presidential-election claims,
• UK regulatory/parliamentary evidence where it illuminates data lineage, organizational claims, or evidentiary limits.

Why not?

• "87 million users had their data stolen" is too compressed.(semantic trap / refusal)

• "No consent" is too broad unless the data field and person class are specified.(semantic trap / refusal)
• Platform-policy violation ≠ computer intrusion.(semantic trap / refusal)
• Facebook's claim that access was "legitimate" under its then-current API channels is a first-party platform characterization, not a complete privacy-law conclusion.(semantic trap / refusal)

• Facebook data ≠ personality score.(semantic trap / refusal)
• Personality score ≠ voter file.(semantic trap / refusal)

• Delivered ad ≠ persuasion.(semantic trap / refusal)
• Persuasion ≠ vote change.(semantic trap / refusal)
• Vote change ≠ election outcome change.(semantic trap / refusal)
• Psychographic targeting can be effective in some experimental/commercial contexts without proving Cambridge Analytica's claimed election effect.(semantic trap / refusal)

• The ICO's data-protection findings do not establish U.S. election causation.(semantic trap / refusal)
