I first provide some context about Cambridge Analytica's (ca) activities, linking them to ca parent company, scl Group, which specialised in "public relations"campaigns around the world across multiple sectors (from politics to defence and development), with the explicit aim of behavioural change. I then analyse in more detail the claims made by mathematician and machine learning scholar David Sumpter, who dismisses the possibility that ca might have successfully deployed internet psychographics (e.g. online personality profiling) in the winning 2016 Trump presidential campaign in the US. I critique his arguments, pointing at the need to focus on the bigger picture and on the totality of ca methods, rather than analysing psychographics in isolation. This is followed by a section where I use ca whistleblower Christopher Wylie's 2019 memoir to show the important role that in-depth qualitative research and methods akin ethnographic immersion might have played in building ca big data capabilities. I provide an angle on big data that sees it as complementary, rather than in opposition to, human insight that comes from qualitative immersion in the social realities targeted by ca. The concluding section discusses additional questions that should be explored to gain a deeper understanding of how big data is changing political campaigning, with an emphasis on the important contribution that anthropology can make to these crucial debates.
