OU SE TROUVE LA LIMITE ENTRE LE VRAI ET LE FAUX ?

The lecture provides a compelling and well-argued exploration of disinformation, drawing on a wide range of historical examples to illustrate its mechanisms. Pretalli’s expertise in Renaissance literature and military deception lends authority to his analysis, and he effectively demonstrates that disinformation is a timeless human phenomenon. The structure is clear, moving from definition to concrete cases, and he highlights key techniques such as the use of a ‘kernel of truth’ and the importance of vraisemblance. The examples are well-chosen and vividly narrated, making the content engaging and accessible. However, the lecture is more descriptive than analytical, offering limited theoretical framework or systematic comparison. While Pretalli mentions his own publications, he does not cite specific academic sources during the talk, which somewhat limits the verifiability of his claims. The discussion of the Brexit graphs is particularly effective in showing how truthful data can be presented misleadingly, but he could have delved deeper into the psychological and sociological factors that make individuals susceptible to disinformation. Overall, the lecture is informative and thought-provoking, but it would benefit from a more rigorous academic grounding and a clearer conclusion on the boundary between truth and falsehood.

The title poses a philosophical question, and the lecture addresses it through historical cases of disinformation, effectively exploring the boundary between truth and falsehood.
