How your behaviour became a commodity

Shoshana Zuboff spent years trying to understand what was genuinely new about the companies that emerged from Silicon Valley in the early years of this century. Her answer, developed over 700 pages of The Age of Surveillance Capitalism, is that they invented a new economic logic — one that treats human experience as raw material to be extracted, processed, and sold.

The term she coins, 'surveillance capitalism', describes a system in which the primary product is not a service but a prediction. The data your behaviour generates — every search, every pause, every purchase, every route taken — is harvested to build models that predict what you will do next. These predictions are then sold to advertisers and others who want to influence that behaviour.

Zuboff argues this goes beyond advertising. The goal of surveillance capitalism, in her analysis, is not merely to predict behaviour but eventually to modify it — to nudge, prompt, and shape human action at scale in ways that serve commercial interests without the knowledge of the people being influenced. She documents early experiments at Google and Facebook designed explicitly to test whether emotional state could be modulated through feed curation.

What makes this a system of power rather than simply a market, in Zuboff's account, is its asymmetry. The companies know an enormous amount about you; you know almost nothing about their models, their aims, or the ways your data is being used. She calls what is lost 'the right to a future tense' — the ability to act without being anticipated and redirected.

The book is long and forensic, but its argument is important: that what looks like a convenient free service has, embedded in it, a claim on human autonomy that we have not collectively decided to grant.
