The article "Liquid Information in the Post-truth Era" by Alejandro Ramos Chávez explores the concept of "post-truth" and its implications in the digital age. The exponential growth of the term "post-truth" is attributed to the global influence of political and social processes, as well as the characteristics of how individuals obtain, generate, and exchange information, which are increasingly linked to internet usage and digital social networks. The author aims to analyze the concept of post-truth, its theoretical issues, and proposes the idea of "liquid information," inspired by Zygmunt Bauman's concept of modernity. Liquid information is defined as unverified, unsupported, or confirmed information, contrasting with solid information, which is documented, reasoned, and enriched with verified data. The analysis considers current sources for information acquisition and the generation of public opinion. The article also discusses the impact of technology on information consumption, the role of social media, and the challenges posed by the rise of misinformation and fake news. Finally, it emphasizes the importance of libraries and information professionals in providing reliable sources and fostering critical thinking among citizens.The article "Liquid Information in the Post-truth Era" by Alejandro Ramos Chávez explores the concept of "post-truth" and its implications in the digital age.
