Natali Helberger and Marijn Sax from Personalised Communication will enter into debate with the makers of a documentary about how Big Data, algorithms and persuasive strategies are used to influence our behavior as voters, consumers, readers and citizens. What are the implications of data-driven persuasion strategies on our autonomy, attention and even our political choices? What does it mean that major internet companies know more about us than we do? What goals do data-driven persuasion strategies serve? And what is the role of the law, regulation and governments? Do we need a code of algorithmic ethics? The debate is organized by the Dutch public broadcaster VPRO, and part of the successful Tegenlicht Meet Up series. It takes place on 28 September from 2000 onwards in Pakhuis de Zwijger in Amsterdam. The debate (in Dutch) can also be followed via life stream. Entrance is free, registration needed.
