O mundo do avesso by Letícia Cesarino is a work that requires courage – to be written and to be read

This review aims to describe and reflect on the main ideas contained in the work, O mundo do avesso: Verdade e política na era digital by Letícia Cesarino, a Brazilian anthropologist, researcher, and teacher. The author explains that understanding contemporary phenomena such as populism and disinformation first requires observing the technical dimension of their infrastructures - relying on the cybernetic perspective of Gregory Bateson to explain her central argument. As a result, Cesarino develops a powerful and disruptive work that envisions new possibilities for understanding the crises that permeate the current Brazilian sociopolitical scenario and modifies the thinking of her attentive reader.
