What albums and songs are getting a lot of play on your Spotify or iTunes app currently? My guest would say that the music you put in heavy rotation comes down to your unique "listener profile."

Her name is Susan Rogers, and she's a music producer-turned-neuroscientist as well as the co-author of This Is What It Sounds Like: What the Music You Love Says About You. Today on the show, Susan unpacks the seven dimensions of music and how they show up along a varying spectrum in every song. She explains how everyone has an individualized taste for the configuration of these dimensions, and that how closely a particular song aligns with this pattern of sweet spots accounts for whether you like it or not. Along the way, we discuss artists that exemplify these dimensions, how Frank Sinatra injected virility into his music, how part of your musical taste has to do with the way you prefer to move your body, and much more.

Influence comes down to a person's level of authority. When someone is perceived as having power, status, and worth, others readily follow them and comply with them.

Authority isn't just a matter of position. It's also a personal quality.

When people attempt to develop their influence or authority, they tend to focus on learning social skills and changing their behaviors around speech and body language.

But my guest would say that authority isn't about what you learn but who you are, and that once you establish the right lifestyle and mindset, influential behaviors will emerge as a natural byproduct.

Chase Hughes is a behavioral analyst who trains both military operatives and civilians. Today on the show, Chase unpacks the five factors that measure someone's level of authority and produce composure, a state which resides between posturing and collapse. We talk about how so much of authority comes down to having your stuff together, why you should become your own butler, and what Andy Griffith has to teach about leadership. We also talk about the things that kill your authority, and how not to be influenced by false authority.

When Nick Gray moved to New York City, he was a shy introvert with few friends. But he wanted to build up his social network. So he started throwing cocktail parties to meet people. These parties changed his life, and he thinks they can change yours, too.

Nick knows what you're thinking: you don't throw parties, and hosting them is simply not for you. But, he would encourage you not to tune out. He's got a great case for why you should give this idea a try, and just as he does in his book — The 2-Hour Cocktail Party: How to Build Big Relationships with Small Gatherings — Nick is going to lay out exactly how to throw a party that's low stakes and low effort, but will be highly successful in helping you build all kinds of connections.

Today on the show, Nick shares what he's learned from throwing hundreds of parties and refining his hosting technique to a T. He explains why cocktail parties are better than dinner parties (and don't have to involve actual cocktails), the best night of the week to throw a party, why the party should only be two hours long and have a firm end time, how many people to invite, and who to invite when you don't yet have any friends. And he explains why he's a big fan of two things you might be hesitant about — name tags and icebreakers — and why two of his favorite things to include in a party are grapes and a harmonica.

Among people who experience some sort of trauma, what percentage do you think go on to develop post-traumatic stress disorder? A third? A Half? More?

Actually, the answer is 10%. An overestimation of how common it is to develop PTSD after trauma is one of the misconceptions my guest thinks are leading to its overdiagnosis and an underestimation of human resilience.

Dr. Joel Paris is a professor emeritus of psychiatry and the author of Myths of Trauma: Why Adversity Does Not Necessarily Make Us Sick. Today on the show, Joel explains what some of those myths of trauma are, including the idea that it's trauma itself which causes PTSD. Joel argues that PTSD is instead created when exposure to trauma meets an individual's susceptibility to it, and he explains what psychological, biological, and even social factors contribute to this susceptibility. We also get into how the methods used to prevent the triggering of trauma can backfire and how the treatment for PTSD will be ineffective if it only focuses on processing an adverse experience.

You've probably heard of Ernest Shackleton, and his ill-fated Antarctic expedition. The Endurance, the ship on which he and his crew sailed, famously became trapped in ice, sunk, and set the men and their indomitable leader off on an arduous journey to safety and rescue.

But the Shackleton expedition wasn't the only one to meet such a fate, and to become a crucible for leadership. The year before the demise of the Endurance, the Karluk, flagship vessel of the Canadian Arctic Expedition, became icebound and sunk, leaving its crew to trek 80 miles across dangerous ice floes to an island, and its captain to travel 1,000 miles more to obtain rescue for those marooned survivors. 

Buddy Levy shares that compelling story in his new book Empire of Ice and Stone: The Disastrous and Heroic Voyage of the Karluk, and unpacks it for us today on the show. Along the way, he brings out the leadership lessons in planning, maintaining morale, and embodying endurance you can glean from the expedition's two dominant figures: its ostensible leader, who abandoned the ship, and the Karluk's captain, who did all he could to save its shipwrecked survivors.

Years ago, I was flipping through TV channels and came across Hugh Laurie, of Dr. House fame, decked out in 19th-century English gentleman garb. Because I was a House fan, I was curious about what Hugh Laurie sounded like with his native British accent, so I paused my channel surfing to find out.

Then I brought up the title and saw that I was watching Sense and Sensibility. "Ugh. Jane Austen. No way I would enjoy that," I thought. I associated Jane Austen with foo-fooey lady stuff. So my plan was to flip the channel as soon as I heard Dr. House talk British.

Two hours later, the end credits for Sense and Sensibility scrolled down the screen. I had watched the entire thing. Didn't even get up to go the bathroom.

Not only did I watch the whole movie, I remember thinking, "Man, that was really good."

Thanks to Dr. House, my resistance to Austen was broken, and I found myself genuinely curious about her books. So I got the free version of her collected works and slowly started working my way through what are arguably her three best: Sense and Sensibility, Pride and Prejudice, and Emma. And I'll be darned if I didn't truly enjoy them all.

If you're a dude who's written off Jane Austen's work as I once did, perhaps today's podcast will convince you that there's something in it for women and men alike and encourage you to give her novels a try. My guest is John Mullan, a professor of English and the author of What Matters in Jane Austen? John and I discuss the literary innovation Austen pioneered that influenced the likes of Larry McMurtry's Lonesome Dove and will give your social agility a healthy workout. John then explains why soldiers and Winston Churchill turned to Austen during the world wars. We also discuss the philosopher Alasdair MacIntyre's argument that Austen's work was "the last great representative of the classical tradition of virtues," Austen's idea of manliness, and how a man's choice of a wife will shape his character. And John shares his recommendation for which Austen novel men should read first.

Twenty years ago, it didn't seem like a burdensome task to write a handwritten letter to a loved one. Fifteen years ago, it wasn't a big deal to write a long email to a friend. Today, it can feel hard to motivate yourself to tap out a two line response to a text.

The feeling that your attention span has been shrinking over time isn't just in your head. Research by today's guest shows that it is empirically getting shorter and shorter.

Dr. Gloria Mark is the world's preeminent researcher on attention and the author of Attention Span. If you'd like to get a handle on your diminishing powers of concentration, you have to understand how attention works, and that's what Gloria explains in the first part of our conversation. We then get into how multitasking is like drawing on and wiping off a whiteboard and why it makes us feel so frazzled. Gloria then shares the way that personality influences your attention span, including why people who are more neurotic have the shortest attention spans and why conscientious people may not want to use distraction-blocking apps. We then get into how the internet and the shot lengths of modern movies reinforce our short attention spans. In the last part of our conversation, Gloria makes the case that fighting the hindrances to our attention by trying to be focused all the time isn't possible or desirable, and that our goal should be balanced focus rather than hyper focus. She explains how to achieve that balanced focus by leaning into your unique productivity rhythm, taking breaks without guilt, and developing a sense of agency over your attention.

Surviving in the wild can seem like a romantic proposition, at least as it often plays out in popular culture and our imagination. We picture ourselves confidently navigating the obstacles of nature, pulling trout out of mountain streams, and building a snug shelter inside a tree.

But the reality of wilderness survival isn't so rosy. Few people know that better than Jim Baird. Jim and his brother won the fourth season of Alone, a reality show that's actually real, and leaves contestants in the wild to face the elements and live off the land. Today on the podcast, Jim shares his experiences surviving on Northern Vancouver Island for 75 days, and what he learned from them as to what's true about survival and what's simply a myth.

Happiness is the subject of thousands of articles, podcasts, and scientific studies. Yet all this focus on happiness doesn't seem to be making people any happier. In fact, the more they try to be happy, especially by fighting to get rid of bad feelings and cling to good ones, the more unhappy people often become.

My guest would say that the first step in escaping this negative cycle is redefining what happiness even means — thinking of it not as a state of feeling good but of doing good.

His name is Russ Harris and he's a therapist and the author of The Happiness Trap.

Today on the show, Russ explains how struggling against difficult feelings and thoughts just makes them stronger — amplifying instead of diminishing stress, anxiety, depression, and self-consciousness — and how simply obeying your emotions doesn't work out any better. He then unpacks the alternative approach to happiness espoused by Acceptance and Commitment Therapy. With ACT, you allow both hard and pleasant feelings to coexist, and unhook from the latter so that they no longer jerk you around. This allows you to focus on taking action on your values to create a meaningful, flourishing life, or in other words, real happiness.

Dante's Divine Comedy is considered one of the greatest works of literature ever written. The poem not only imagines the three parts of the afterlife, but serves as an allegory for the spiritual journey of the human soul.

Here to take us on a tour of the journey Dante describes is Robert Barron, a bishop in the Catholic Church. Today on the show, Bishop Barron offers a bit of background on the Divine Comedy and how it resonates as a story of the search for greater meaning that commonly arises in your mid-thirties. We then delve into Dante's journey through Inferno, Purgatorio, and Paradiso. We discuss why Dante can't initially climb the redemptive mountain of purgatory and has to go through hell first, the importance of having a tough-but-encouraging guide for any spiritual journey, why hell is an inverted cone that gets narrower and colder at the bottom, and why traitors inhabit its lowest layer. We then get into what it takes to climb Mount Purgatory, why heaven in the Divine Comedy doesn't get much attention, and what Dante finds when he gets there. Along the way, Bishop Barron describes the meaning behind the religious imagery Dante used in his poem, as well as insights that can be applied to any spiritual journey.
