On this episode of Sustainability Matters, we explore what having confidence in science really means. What separates healthy skepticism from deliberate doubt? How do politics, economic interests, and misinformation shape public opinion around scientific research? And what role can scientists themselves play in rebuilding trust?

All this and more with Dr. Peter Mahaffy, member of the International Union of Pure and Applied Chemistry's (IUPAC) Committee on Ethics, Diversity, Equity and Inclusion and contributor to their Chemistry International journal, published by De Gruyter Brill.

Host: Ramzi Nasir
