Science and public policy: how can science influence decision-making?
A day of meetings and debates, organised by the Sorbonne University Alliance, in partnership with Le Monde, on 1 June 2026 from 10am to 5pm.
Introduction
- How can science more effectively shape our world and, in particular, in public policy-making?
- How can scientific expertise become more audible, impactful and influential in public debate?
- How can we reconcile the long-term nature of research with the urgency of political decision-making, the complexity of scientific knowledge with media dynamics and the need for clarity in public action?
- How can scientific findings be translated into concrete recommendations and actionable levers?
These questions, and many more, will be explored by leading voices from the scientific, institutional and political communities.
At a time marked by profound and overlapping crises – climatic, health, social and political – the need for science-informed public decision-making has never been greater. The academic world, with its combination of expert and critical inquiry, has a vital role to play in transforming knowledge into capacity for action.
The event will foster meaningful dialogue between scientists and public stakeholders through round-table discussions, workshops, debates and case studies. The aim is to clarify expectations, share feedback and identify concrete pathways for progress.
Ultimately, the discussions will converge around a shared ambition: how can science more effectively contribute to make a tangible difference?
Please note that the event will be held in French.

The seminar “Science and public policy: how can science influence decision-making?”
The seminar “Science and public policy: how can science influence decision-making?” was initiated by Laurent Petit, Project Officer for ‘Expertise, Media and Society’ as part of the Sorbonne University Alliance’s SOUND project. Its objective is to put forward measures aimed at enhancing the influence and visibility of scientific expertise.
The first season of the seminar, held in 2024, explored the status of the scientific expert and sought to shed light on the complex and often opaque mechanisms underpinning the so-called “influence industries”.
For the second season, in 2025, discussions were framed by the context of the “Year of the Sea” and led to a series of proposed initiatives. Several of these are currently underway, including training in science communication, the creation of a database of expert contacts for the media and the design of educational and awareness-raising tools for young audiences. Others projects are yet to be launched, notably a science-policy interface, which this 2026 edition may help bring to fruition.
An event supported by SOUND
“SOUND – for a new commitment” is a project by the Sorbonne University Alliance funded by France 2030 under the ExcellencES programme. Its main objective is to support the Alliance’s communities in developing a stronger commitment to society, particularly towards external audiences such as those referred to as “decision-makers”.
