The pandemic that took over the world in 2020 was accompanied by a steady stream of data, from the number of positives to swabs, from new hospitalizations to deaths. Never before have we experienced the power of numbers and their variations in directing decisions. And we have also seen how, whenever there is strength, there can be abuse.
This book reflects on data, on its necessity and its delicacy: demographic and migratory trends, environmental issues, even political choices require, in order to be read and experienced without simplistic drifts, a good familiarity with the sea of available data and their interpretation. In a reality increasingly conditioned by algorithms, numerical models and artificial intelligence, the "culture of data" cannot be missing in the training of those who are called upon to make decisions. But above all, it is part of the baggage of skills of every citizen who wants to live with awareness and critical spirit in the world to come.
