In 2014, psychologist Aleksandr Kogan at Cambridge University recruited people to complete surveys through a Facebook app called "This Is Your Digital Life." The app harvested data from approximately 87 million users and their friends without proper consent (Confessore, 2018). Kogan passed this data to SCL, which later founded Cambridge Analytica, a political consulting firm. The data were used to build psychological profiles for targeted political advertising during the 2016 US presidential campaign.

Cambridge University's own psychology research ethics panel rejected Kogan's 2015 proposal for further academic research using this data, finding Facebook's consent approach "falls far below the ethical expectations of the university" and calling it "deceptive" (Guardian, 2018). The scandal went public in March 2018 when former employee Christopher Wylie whistleblew to major newspapers, exposing how innocuous survey data points were "bundled together and trawled by algorithms" to reveal sensitive information users never expected to be disclosed (Nature, 2018).

Ethical Implications: These cases violate fundamental research ethics principles including informed consent, privacy protection, and minimization of harm (Chiauzzi and Wicks, 2019). The Cambridge Analytica scandal exposed critical gaps in research ethics frameworks, as current regulations often exclude internet research from strict oversight unless data are both private and identifiable (Nature, 2018). Participants had no meaningful choice about data use, and sensitive information about political views, psychological traits, and health conditions was exploited without knowledge or consent.

Social Impact: Survey misuse erodes public trust in research institutions and technology platforms. After the Cambridge Analytica revelations, Facebook faced massive user backlash and regulatory scrutiny worldwide. Similarly, when PatientsLikeMe notified members about the Nielsen Media scraping incident, approximately 200 members closed their accounts (Chiauzzi and Wicks, 2019). This demonstrates how ethics violations damage the social license researchers need to conduct valuable public health and social science studies. Vulnerable populations, including those with mental health conditions or stigmatized diseases, face particular harm when their data are misused.

Legal Consequences: The Cambridge Analytica scandal prompted global regulatory action. Facebook faced a $5 billion fine from the US Federal Trade Commission and was investigated by multiple international regulators. The incident accelerated implementation of data protection regulations like the European Union's General Data Protection Regulation (GDPR), which imposes strict requirements on data collection, processing, and consent. The scandal also sparked ongoing discussions about potential regulations for Big Tech companies to protect consumers from weaponization of private data (Nature, 2018).

Professional Implications: Survey misuse raises questions about disciplinary standards and oversight. Computer science researchers increasingly access health data but may lack training in research ethics that medical and social science professionals receive (Chiauzzi and Wicks, 2019). The LaCour fabrication damaged reputations across multiple institutions and highlighted gaps in peer review processes. For practitioners, these cases demonstrate that technical capability does not excuse ethical responsibility. Professional bodies now face pressure to develop clearer standards for social media research, with institutional review boards requiring expertise in online research methodologies to properly evaluate ethical applications.
