The relationship between politics and science is changing in many parts of the world with policy-makers ignoring scientific evidence when making decisions that affect their constituents and the whole world. Facts and rationality are being challenged by emotion, belief, pre and post-truths, and not only by policy-makers but also by citizens.
Social media has become a prominent communication channel with a fast and large dissemination power, and yet with a limited possibility to develop sound rationales.

One of the main roles of science centres and museums is to help citizens grasp the difference between authority-based and science-based statements. How are they adapting their strategies to a new context where the notion of scientific evidence is challenged and where social media acts as an amplifier?
