In this episode, we speak with researcher Jakub Šrol about how conspiracy theories threaten sustainability efforts. Drawing on his new paper published in the journal Nature Human Behavior, he discusses how belief in conspiracy theories erodes confidence in science and institutions and how social media accelerates misinformation. The conversation covers what defines a conspiracy theory, how to spot telltale signs online, and practical steps—like education and stronger public engagement—to slow the spread of disinformation and protect sustainable policies.
