The face we give to our monsters says much about our anxieties as a culture. But birds? Two classic works of 20th-century horror featured a violent avian army. This podcast looks at why a Daphne du Maurier short story, and the Alfred Hitchcock thriller inspired by it, imagined “The Birds” as humanity’s mortal enemy. Seeded with fears of technological overreach and environmental disaster, and terror at the rise of the violent irrational, our reality was anticipated. *This episode originally aired on Sept. 6, 2023.

There are 19 centibillionaires and a growing list of 3,000 billionaires worldwide. So it might not surprise you that the richest one per cent possesses nearly half of the world’s wealth. History has never seen such an extreme concentration of wealth. Some economists argue the battle of the 21st century is between oligarchy and democracy. How did we get here? IDEAS begins a four-part documentary series The Billionaire Age.

Earthworms are supposed to be a sign of healthy soil. But they're actually an invasive species that can even damage forests. So have we been sold a lie about worms and soil? Not exactly. The relationship between the two depends on the context. And the way we garden — or farm — can make all the difference. IDEAS producer Annie Bender unearths the complicated truth about the not-so lowly earthworm.

In more than 40 years on the front lines of international human rights Alex Neve has heard Canada described as ‘the land of human rights’ — and seen the profound ways Canada has failed to uphold universal human rights, both at home and abroad. In his final Massey Lecture, he lays out his vision for a way forward.

The bombing of civilians has been called one of the "great scandals" of modern warfare. So why, despite nearly a century of drafting laws and signing conventions protecting the sanctity of human life, does bombing civilians remain a widespread military tactic? IDEAS producer Naheed Mustafa looks at a century of bombing civilians to try and answer that very question.

"Our democracy is what’s at stake," says Karen Hao, an engineer who used to work in Silicon Valley. Now she’s an outspoken critic of its AI giants. The investigative journalist argues AI companies run their businesses like empires and it has to stop. In her 2025 bestseller, Empire of AI, Hao digs into the global impact of Big AI and explores how we need to rethink AI to build a better future. This podcast includes a lecture by Karen Hao and a discussion with host Nahlah Ayed.

Fact and fiction may seem poles apart but writers Esi Edugyan and Tiya Miles find the two intertwine perfectly in their award-winning storytelling. Both authors try to imagine past lives in their work, in part so that we may reimagine our own. They may operate in different realms but what they share is the telling of profoundly important stories that would otherwise go untold. It's been a longtime goal for IDEAS to bring these two accomplished authors together for a discussion — and it was worth the wait.

This podcast was recorded in front of an audience in January 2026 at a Toronto Public Library event.

Poetry can find you when you need it most. It can be life-altering to read that poem just at the right moment. It was for six IDEAS producers who join Nahlah Ayed in studio to share poems they return to, year after year.

This special episode is to mark UNESCO's World Poetry Day, March 21st.
