Cawthron Annual Lecture – Truth in a Noisy World

How can we find truth in a noisy world? At a time when our biggest environmental challenges demand informed action, the ability to distinguish evidence from opinion has never been more important.

From social media algorithms to artificial intelligence, the way information is created, shared and consumed is changing rapidly. These technologies have transformed how we understand the world around us, but they have also made it easier for misinformation and disinformation to spread, shaping public debate and influencing decisions that affect our communities, our environment and our future.

In this year’s Thomas Cawthron Memorial Lecture, award-winning environmentalist and author Natalie Kyriacou OAM will explore how disinformation has evolved from a tool used to influence consumer behaviour into sophisticated systems capable of influencing beliefs, identities and public understanding.

Drawing on examples from environmental and social issues, Natalie will examine why these challenges matter, and what individuals and institutions can do to strengthen critical thinking, rebuild trust and create healthier information ecosystems. Following the keynote address, Professor Trisia Farrelly ONZM, Senior Research Scientist and General Manager Donor Relations at Cawthron Institute, will reflect on the vital role of independent science in addressing complex environmental challenges.

Drawing on her international work at the science-policy interface, she will explore why robust evidence, transparency and public trust are essential for effective decision-making in an increasingly uncertain world. Together, the speakers will consider one of the defining questions of our time: how do we ensure good decisions are guided by evidence when trust is under pressure and information is increasingly contested?

Join us for an evening of insight, challenge and optimism as we explore how science, informed public dialogue and critical thinking can help shape a more sustainable future.
