In 1984, on the eve of the Winter Olympics, Joe Boylan gets lost in a blizzard on an Austrian mountainside. Joe will have to fight with everything he has to survive and be reunited with his family. How he does it reveals often typical patterns of behaviour exhibited by lost people in similar situations.

Through the story of Joe’s extraordinary 48-hour battle against the wilderness, Matthew Syed examines the fascinating area of study called Lost Person Behaviour, which has changed the way search and rescue teams operate, world over.

Featuring Joe Boylan, Robert J Koester, mathematician and author of Lost Person Behavior, Alistair Read from Mountain Rescue England and Wales, Neil Balderson of Lowland Rescue and Maura O'Connor, science journalist and author of Wayfinding: The Science and Mystery of How Humans Navigate the World.

In 1972, at the liberal Vassar College in New York, 18-year-old Rick Shenkman stood out for his unwavering support of Richard Nixon, especially as the Watergate scandal unfolded. His unconditional allegiance raises a perplexing question - why would a bright, well-educated student overlook the facts and maintain blind faith in the president?

In this episode, Matthew Syed delves into one of the most intriguing facets of human psychology - cognitive dissonance.

Conceptualised by Leon Festinger in the 1950s, cognitive dissonance refers to the mental discomfort a person experiences when they hold contradictory beliefs, values, or attitudes simultaneously, or when their behaviour conflicts with their beliefs or values. While we all encounter cognitive dissonance in our daily lives, its underlying mechanisms often remain unnoticed despite their profound impact.

Featuring journalist and historian Rick Shenkman, Professor Elliot Aronson, Professor Matt Johnson and Princeton University graduate student, Logan Pearce.

As a child, Kate Ertmann starred in commercials, in soap operas and on Broadway. But acting wasn’t her first love - mathematics was. She considered it to be “a balm" for her brain. And yet societal and teenage pressures made her turn away from maths.

Growing up in Sweden, Sebastian Nillson Qvist loathed maths and found it a real struggle. But he still challenged himself to study it as part of a Political Science and Economics degree. It did not go well.

But still, maths came back into their lives.

In this episode of Sideways, we find out what led them back to mathematics and the impact it had on them. Something host Matthew Syed experienced first hand when a desire to understand inflation and economics led him back to studying for a maths A-Level in his own time and finding it actually enjoyable, rather than a chore as he had at school.

We hear how determination to dominate in the sport of darts can lead to incredible mastery of mental arithmetic from Professor Marcus du Sautoy, who also suggests a novel approach to maths education which he believes could inspire and motivate children. And Field’s Medal winner Professor Efim Zelmanov introduces us to a brilliant young mathematician who was killed in a duel 150 years ago but left behind a theory which keeps all online banking safe.

With Kate Eartmann of katelovesmath.com, Sebastian Nillson-Qvist, Professor Marcus du Sautoy - Simonyi Professor for the Public Understanding of Science and Professor of Mathematics, and Professor Efim Zelmanov - Field’s Medallist and Director of the Shenzhen International Center for Mathematics.

In 2020, David Gutenmacher began to buy old photographs and videos that he came across in second hand shops. He was sad about the prospect that families had been severed from their treasured memories, and so he founded the Museum of Lost Memories to try and reconnect people with their personal archives.

But when he came across a video of a family on a safari holiday he realised that finding out who was in these videos might not be all that straightforward.

Matthew Syed considers the role of photography and video in personal memory making, and how we go about using photos to leave a record of our existence on earth.

Featuring: David Gutenmacher, Founder and curator of the Lost Memory Museum Jono Marcus Lina Henkel, professor of psychology at Fairfield University

Lee and Drew have been like brothers ever since adolescence. So when Drew betrays Lee in the heat of a tumultuous night in Glasgow, the two men find themselves entangled in a bitter grudge that went way beyond what they could imagine, as the violence and bitterness of the wrestling ring, spilled over into the real world.

Grudges are typically seen as dangerous, negative emotions. But is there a glimmer of light to be found amid the darkness of resentment? Matthew Syed questions both the hidden values and harsh consequences of grudges.

Featuring WWE superstar Drew McIntyre, ICW champion and professional wrestler Lee Greig, Pr Robert Enright from University of Wisconsin and writer Sophie Hannah.

Matthew Syed kicks off the new season of Sideways with a story of one of the most brutal grudges ever seen in pro wrestling. Matthew asks us to consider when it's time to let go of a grudge and how.

On a summer's day in 1974, Norwegian actor Knut Risan steps up to the mic for a voiceover job. It's for a Cinderella movie that's just been acquired by the Norwegian broadcaster NRK, from the country known at the time as Czechoslovakia.

NRK want him to dub the film into Norwegian. Knut's just having fun. He's doing all the voices, even the young Cinderella. But he's about to become Norway's "Voice of Christmas" when NRK decides to put the film out as part of its festive line up.

Tři oříšky pro Popelku or, as it's often translated, Three (Hazel)nuts for Cinderella, remains an essential part of many Europeans' seasonal viewing to this day. Not least in Norway, where it is shown at 11am on Christmas Eve every year.

Knut's son, Olav, used to feel a little embarrassed around this time of year - everyone knew he was the son of the most famous voice on TV. He'd get strange looks in supermarkets. But today, and in this episode of Sideways, he reflects on the special place his father's voice occupies in Norway's Christmas and in his own family.

Through the story of a film that straddles the line between fairy tale fun and the realities of the Iron Curtain, Matthew Syed explores the origins, meaning and persistence of this cross-cultural tradition and celebrates the role of Christmas films in many families' celebrations, including his own.

Featuring musician Olav Risan and author Kathrin Miebach of the Drei Haselnüsse für Aschenbrödel website. With fairy tale expert Professor Claudia Schwabe of Utah State University and Michal Bregant, Director of Národního Filmového Archivu.

Including clips from Tři oříšky pro Popelku (Czech language version) and Tre nøtter til Askepott (Norwegian language version, featuring the voice of Knut Risan). Tři oříšky pro Popelku directed by Václav Vorlícek and starring Libuse Safránková and Pavel Trávnícek. Written by Božena Němcová (story) and František Pavlíček (screenplay), produced by Jiří Krejčík and with a score by Karel Svoboda. Distributed by Ústřední půjčovna filmů.

David Henty had a talent for art from a young age. He grew up poring over Hogarth drawings. For a long time, it didn’t feel like something that he could easily pursue. But after two prison sentences spent painting as much as he wanted, there was no looking back. David was set on making a living as an artist. The thing is… the only paintings he could manage to sell for any profit, were all forgeries of famous artists like Lowry, Bacon and Picasso.

Matthew Syed explores how David's copy cat approach to art allowed him to unlock his own creativity.

Matthew delves into the world of art forgery to explore how this practice blurs lines between creativity and imitation, and challenges notions of authenticity in the art world. He considers whether copying is actually a necessary step on the way to becoming skilled at a particular craft, and whether forgers - as pranksters - might even qualify as modern conceptual artists, and also ponders how the rise of artificial intelligence platforms might make forgers of us all.

Featuring: David Henty, artist and writer, Austin Kleon, artist and philosopher, Jonathon Keats, and BBC journalist and AI expert Lara Lewington.
