“One of your tribe is enough.” That’s what Margaret Rossiter was told when she said she wanted to study female scientists. Nevertheless, Rossiter persisted. She found and documented hundreds of women whose contributions to science had been overlooked, under-credited and misappropriated. Then she made history herself by coining the term “The Matilda Effect” to describe why those women failed to get...

Our inherent human rights belong to us from the moment we are born. There is nothing we need to do to earn them, and they are supposed to apply to us until the day we die. But in his third Massey Lecture, Alex Neve argues the powerful have made human rights a ‘club.’ Visit cbc.ca/masseys for more on this lecture series.

One of the strongest ties between the diaspora and home is music. In Iran, music can be politically contentious. In Canada, it connects a community to its past and to its future. Days after the bombings began in Iran, Nahlah Ayed spoke to three Iranian-Canadian musicians and composers about the role of music in a time of uncertainty. "Music can be an escape, can be a consolation... Like if we are...

Anxiety is an inescapable, fundamental human reaction to an unpredictable future. This is the philosophy of Thomas Hobbes, a curmudgeon of the 17th century who believed that without a powerful, sovereign government life would be "nasty, brutish and short." Politics and uncertainty go hand in hand. In this podcast, IDEAS explores how a new take on Hobbes on the topic of anxiety offers a surprising...

Mathematics is everywhere: a common refrain from high school math teachers. But did you ever think math could be linked to literature? And not just in works from the literary greats of the past but for example Michael Crichton's Jurassic Park . The relationship between math and literature are fundamentally creative, says Sarah Hart, a mathematician and author who speaks to Nahlah Ayed about how th...

It is possible. Flavours have been lost to the past, as culinary physicist Lenore Newman explains. She points to the extinction of the passenger pigeon — a species numbering in the billions throughout North America — as an example. In 1914, Martha, the last passenger pigeon, died at the Cincinnati zoo — and in place of the pigeon, came the industrialized farming of chicken. Newman says we're now t...

The ideals behind the concept of human rights — such as the sacredness of life, reciprocity, justice and fairness — have millennia-old histories. After the carnage of the Second World War and the Holocaust, these ideas took a new legal form. In his second Massey Lecture, Alex Neve considers six dizzying years that laid out a blueprint for a new world. Visit cbc.ca/masseys for more on the series.

At a time when the future of Iran is uncertain, we revisit an IDEAS documentary about the history of women’s resistance in Iran — women who in 1979 harboured dreams of freedom and democracy. After ousting the Shah, and mere weeks after Ayatollah Khomeini took power, Iranian women marched to show their fury at the revolution. Forty years after their protest, documentary maker Donya Ziaee spoke to t...

Accusations of a stolen election, laws targeting NGOs and media, violent treatment of protestors — sometimes live on TV. What’s happening in the republic of Georgia right now typifies what is happening geopolitically around the world. The authoritarian ruling party called Georgian Dream aligns itself with Russia but most citizens want the country to join the European Union. There have been 400 con...

That’s what Hanna Pickard argues. After analyzing the scientific research, and working with those who’ve stopped self-destructive drug and alcohol use, the Johns Hopkins philosopher sees addiction as a complex behavioural disorder. She argues it’s driven by individual psychology and social circumstances, and should be treated that way. Jowita Bydlowska and Michael Kaufmann, both memoirists of addi...

Connie Greyeyes describes herself as an ‘accidental activist.’ After her cousin was murdered and her childhood best friend went missing, she started organizing vigils for missing and murdered Indigenous women in Fort St. John, B.C. — then asking questions about the relationship between resource extraction and violence against women. This episode is the first in a series of profiles of human r...

Universality is the core promise of human rights: these rights extend to everyone, everywhere. But above all else, this is where we have failed. In his first CBC Massey Lecture, Alex Neve explores how to ensure the “lifeboat” of human rights is seaworthy for everyone.  Visit cbc.ca/masseys for more details about this lecture series.

You likely have never heard of Matilda Joslyn Gage. Gloria Steinem calls her “the woman ahead of the women who were ahead of their time.” Matilda worked side by side with Susan B. Anthony and Elizabeth Cady Stanton to get women the vote in the United States and co-wrote the history of the women’s movement with them. IDEAS producer Dawna Dingwall looks into why the towering figure was erased by her...

There are two things most people agree on — artificial intelligence is rapidly advancing, and the grave risks AI poses are very real — no one, not even ChatGPT, really knows how this will play out. Renowned “Godfather of AI” Geoffrey Hinton argues we need to put the brakes on AI development until we know for sure it can be kept safely under control. Owain Evans is a leading AI researcher and the f...

And it is dying. At least for us, humans. Our chatter and connection online is being overrun by bots — more than half of online activity is non-human. The internet is on it's way to feeling haunted, like a deserted mall where the fountain is still gurgling, the canned music is still playing, but the people are nowhere to be found. IDEAS explores the dying internet and what we will do when it's dea...

It was a simple honeymoon photo from 1941. A stranger posted it online and the commentary was vicious. The woman in that picture was Albanian author Lea Ypi’s grandmother. In the midst of the Second World War and the violent end times of Mussolini’s government, Ypi’s grandmother must have been a fascist, a collaborator, a traitor to Albania. In her book, Indignity: A Life Reimagined , Ypi attempts...

When he was eight, 2025 CBC Massey Lecturer Alex Neve watched his mother fight for daycare in Alberta. It’s shaped how he thinks about human rights activism. Neve shares the pivotal moments in his life that led to his human rights advocacy — and shines a light on the chorus of people he carries with him. *This episode originally aired on Nov. 14, 2025.

Thanks to AI, it's easier than ever to avoid reading books — but that convenience may come with a cost. IDEAS explores how our digital landscape, coupled with the decline of reading, is changing the way we think. If you like this episode, listen to our podcast with Geoffrey Hinton , the 'godfather of artificial intelligence' who says AI must develop empathy and 'maternal instincts' or we risk huma...

If AI continues to develop without appropriate guardrails, a worst-case scenario could lead to human extinction, warns the 'godfather of artificial intelligence ' Geoffrey Hinton. But the Nobel Prize winner has a solution: AI must foster 'maternal' instincts, empathy and kindness. Hinton tells host Nahlah Ayed that it's fairly inevitable AI will become smarter than humans, but if we could make it...

IDEAS producer Tom Howell recently sold his car and joined the ranks of winter cyclists in Montreal. He is not the only one who commutes on bike in North America’s snowiest metropolis. The city’s bike-sharing program operates year-round. The bicycle’s popularity as a winter vehicle is increasing. Nevertheless, winter bicycling remains a minority practice, often viewed as folly. Howell investigates...

Under pressure, our nerves can take over. At job interviews, performing in front of an audience and it's definitely present in sports. But why do our skills desert us at such a crucial moment? And what can be done to avoid choking? Studies have shown that when people tell themselves they're excited rather than nervous, they perform better. This podcast explores more ways to avoid the choke and why...

Henry Brown earned the name "Henry Box Brown" in March of 1849. He hatched a risky plan and had himself shipped in a wooden crate, from Richmond to Philadelphia. But that’s less than half his story. In freedom, he uses his escape box as the basis for a subversive magic act that sees him tour the stages of the UK and Canada — his final home. Henry's remarkable story is a must-listen. *This episode...

With vengeful alien civilizations and hologram wives, Chinese science fiction is in its heyday. One hot topic discussion is how the genre and culture view things as "inherently non-binary," says PhD student Zichuan Gan. Not just in the sense of gender but avoiding black and white categories. As in "humans or machines, west or east, Chinese science-fiction often shows that reality and life are more...

Neither the legal system nor the Constitution can change the course of the United States’ descent into illiberalism, argues human rights and civil liberties lawyer Jameel Jaffer. Only the will of the people can — when ordinary citizens fight to uphold democracy with "civic courage."

Mudlarking is a hobby that's having a moment. The opportunity to take part in the painstaking, low-tech scrape through history draws thousands of people hoping to come face to face with the remnants of lives that came before them. But what can mudlarkers do that a trained archeologist cannot? This podcast takes you to the heart of London on the Southbank of the Thames River where there's mud, wate...
