Facts change — and that’s a good thing.

In this episode, Samuel Arbesman, complexity scientist and author of The Half-Life of Facts, joins Aidan McCullen to explore how what we know — and believe to be true — constantly evolves.

Together, they unpack how facts have a “half-life,” why collaboration matters in a changing world, and how exponential knowledge growth reshapes science, strategy, and society.

In this episode:

• Why facts and truths decay over time

• How science self-corrects — from the Brontosaurus myth to the spinach iron story

• The concept of “meso-facts” — slowly changing knowledge

• How exponential growth drives innovation and discovery

• Why curiosity, humility, and adaptability are essential for leaders
