  • Cyril Labbé (SIGMA): Nano bubbles: how, when and why does science fail to correct itself? Slides and Video

    To advance, science relies on the correction of errors. Yet in practice it can be difficult to erase incorrect and exaggerated claims from the scientific record. To understand how error correction works and what obstacles it faces, the NanoBubbles project will combine approaches from the natural, information technology, and social sciences and the humanities (Science and Technology Studies) to understand how, when and why science fails to correct itself. Scientometrics and text analysis offer exciting tools for analysing scientific debate.

  • Barry Pradelski (POLARIS): Green bridges: Reconnecting Europe to avoid economic disaster. Slides Video

    The Covid-19 pandemic has challenged our ways of living and has shown to require new interdisciplinary efforts to guide policy response. We proposed green zoning in April 2020 to safely exit the first lockdown. ‘Green zones’—areas where the virus is under control based on a uniform set of conditions—can progressively return to normal economic and social activity levels, and mobility between them is permitted. By contrast, stricter public health measures are in place in ‘red zones’, and mobility between red and green zones is restricted. I will review the evidence why green zoning can be an effective policy tool and also discuss our experience with interacting with policy makers and the public. Finally, I will discuss the link between green zoning and the strategic choice to aim to eliminate the virus.

15:00 - 16:30: COVID and post-COVID organization
