Intelligence services, government administrations, businesses, and a growing majority of the population are hooked on the idea that big data can reveal patterns and correlations in everyday life. Initiated by software engineers and carried out through algorithms, big data has sparked a silent revolution. But algorithmic analysis and data mining are not simply byproducts of media development or the logical consequences of computation. They are the radicalization of the Enlightenment's quest for knowledge and progress. Data Love argues that the "cold civil war" of big data is taking place not between citizens or the citizen and government but within each one of us. Roberto Simanowski elaborates on the changes data love have brought to the human condition while exploring the entanglements of those who--be it out of stinginess, convenience, ignorance, narcissism, or passion--contribute to the amassing of evermore data about their lives, leading to the statistical evaluation and individual profiling of their selves.
