Exploring Big Data's Impact on Social Sciences and Ethical Paradigms

This work by Alessandro Panconesi delves into how big data transforms our understanding of social networks. It discusses the interconnectedness of individuals through short acquaintance chains, exemplified by a 30% success rate in message delivery. With a focus on the predictive power of computational statistics and the emergence of hybrid science, the text also examines ethical implications such as privacy concerns. Drawing upon classic literature, it raises critical questions about the surveillance of society by powerful entities and the necessity of new algorithms in data processing.

  21. ETHICAL ISSUES

  22. No one would have believed in the first years of the XXI century that this world was being watched keenly and closely by awesome computing and financial powers; that as people busied themselves about their various concerns they were scrutinised and studied, perhaps almost as narrowly as a person with a microscope might scrutinise the transient creatures that swarm and multiply in a drop of water. … Adapted from “The War of the Worlds” by H.G.Wells

  23. All'inizio del XXI secolo nessuno avrebbe mai creduto che il nostro pianeta fosse sotto osservazione da parte di entità cibernetico-finanziarie di inimmaginabile potenza e che mentre l'umanità si affaccendava nella sua quotidianità i suoi movimenti venivano osservati da vicino da occhi cupidi, allo steso modo in cui i batteri che pullulano e si moltiplicano sono studiati attentamente al microscopio… Adapted from “The War of the Worlds” by H.G.Wells

  24. FINAL REMARKS • Paradigm shift in the social sciences? • Computational Statistics (more predictive power) • Hybrid science: data processing CANNOT be naïve • New algorithms are the key • Ethical caveats apply (privacy etc)

  25. Thanks
