Os saberes Clandestinos: navegando nas ciências do Sul Global

Value of the Information & Strength of the Argument

The value of the information lies in its rich theoretical synthesis of decolonial thought applied to science communication and education. The speakers provide concrete conceptual tools—such as the criteria to distinguish denialism from traditional knowledge—that are immediately useful for practitioners. The argumentation is solid: Natália anchors her critique in historical references (e.g., 1930s science writing) and contemporary publications (the article by Rosa, Alves Brito, and Karine). She carefully avoids relativistic traps by insisting on the falseability and community validation of traditional knowledges. The panel exemplifies a collaborative, cross-disciplinary approach, integrating astronomy, physics, history, and education. The use of metaphors like ‘multiple compasses’ and ‘barquinhos de papel’ enriches the discourse, making complex ideas accessible without oversimplifying.

Scientific Rigor, Source Quality, Title Accuracy

The speakers cite specific scholarly works and authors, such as Carl Sagan’s ‘The Demon-Haunted World,’ the article ‘Pós-verdade para quem?’ by Katemari Rosa et al., and the work of Anna Tsing and Nego Bispo. These references are pertinent and give the discussion an academic grounding. However, the citations are made in passing without formal references, and no external links are provided in the video description. The title accurately encapsulates the theme, and the content delivers on the promise of exploring clandestine knowledges in the Global South. The structure is that of a round-table conversation, which is coherent for a conference panel. No comments were available to analyze public reception.

The title accurately reflects the central theme: examining marginalized knowledges and counter-hegemonic scientific practices in the Global South. The content aligns closely with this framing.

8/10

The panel brings together recognized academics and practitioners (historian, physicists, astronomer) with strong institutional affiliations. They discuss decolonial epistemologies and science communication with nuanced arguments, referencing scholarly works and projects. The tone is reflective and rigorous, though the format is a discussion rather than a peer-reviewed presentation.

Markers derived by PSI from the transcript: the creator did not define chapters.

• 12:00Introductions and the panel begins with acknowledgments to staff and a poetic reading of Thiago de Melo's 'Estatuto do Homem'.
• 30:00Natália Amarinho starts her talk, critiquing the 'Promethean' image of science communicators and the hierarchical model of knowledge dissemination.
• 1:05:00Discussion on distinguishing scientific denialism from traditional knowledges, listing criteria such as interests, verifiability, and historical depth.
• 1:30:00Sharing of educational materials and projects: the constellation map of the Tukano people, the 'Dance of the Sun' calendar, and the audiovisual project 'Ciência, Cultura'.
• 2:00:00Closing reflections on institutional policies (e.g., UFMG's public science communication policy) and epistemological patchwork, followed by final thanks.

• O mundo assombrado pelos demônios (The Demon-Haunted World) — Mentioned by Natália Amarinho as an example of the 'Sagan-esque' aesthetics in science communication, where science is presented as a light against ignorance.
• Pós-verdade para quem? (Post-truth for whom?) — Article by Katemari Rosa, Alan Alves Brito, and Bárbara Karine, referenced to argue that hegemonic scientific argumentation is itself a post-truth state for Black people.
• Anna Tsing's concept of 'justaposição' (juxtaposition) — Used by Natália to describe placing different knowledges side by side without forced translation.
• Nego Bispo's 'confluência' — Referenced as a similar concept to Tsing's, emphasizing coexistence of knowledges.

• Decoloniality in Science Studies — Provides theoretical background consistent with the panel's arguments about hegemonic epistemologies.
• Traditional Ecological Knowledge — Supports the idea that indigenous knowledges are cumulative and adaptive, echoing the speakers' points.
