Episode Title: The Art of Exploration — Why We Seek New Challenges and Search Out the Unknown
Host: Brett McKay
Guest: Alex Hutchinson, Author of "The Explorer’s Gene"
Date: March 25, 2025
Overview
This episode investigates the deep-rooted human drive to seek new challenges and explore the unknown. Host Brett McKay interviews Alex Hutchinson, author of The Explorer’s Gene, about the science behind exploration—its genetic, cognitive, motivational, and evolutionary underpinnings. Together, they examine why some people (and cultures) are more driven to explore, how exploration changes across the lifespan, and practical insights into keeping this impulse alive throughout life.
Key Discussion Points & Insights
1. What Drives the Human Urge to Explore?
[00:13–06:51]
- Humans are unique in their compulsion to explore, venturing into even the most inhospitable or unknown places with intention.
- Alex shares personal stories of backpacking in remote places like Tasmania, connecting these experiences with broader questions about human curiosity and the desire to go beyond the obvious.
- The urge to take the road less traveled isn't always logical—sometimes the drive is as simple as wanting to find out what's out there, even if it's more difficult or riskier.
Quote [04:06]:
"Somehow on these trips, I was really drawn to the idea of getting out into the unknown. And I. I didn't really know why. I didn't know what I was looking for. ... I have this drive to find out, to try the new thing, to try the unknown thing. And I wondered what that was all about." — Alex Hutchinson
2. Are Humans Unique Explorers in the Animal Kingdom?
[06:51–13:14]
- Debate exists about whether only humans have this exploratory nature.
- Polynesian navigation is highlighted as a dramatic example—settlement of far-flung islands required deliberate, intentional exploration, not just random drift.
- The Polynesian Voyaging Society and experimental voyages proved it’s possible to navigate vast distances using traditional knowledge, reinforcing theories of intentional exploration.
Quote [09:02]:
"When you're looking at, like, how did we get to Easter Island? ... You only get to Easter island by being like, I want to know what's over that horizon and I'm going to go sail in that direction." — Alex Hutchinson
3. The Explorer’s Gene: Is There a Genetic Predisposition?
[13:05–18:57]
- Alex clarifies that there isn’t a single "explorer gene," but one particular dopamine receptor (DRD4) variant has been linked to increased novelty-seeking behavior.
- Populations whose ancestors migrated farther tend to have a higher prevalence of this gene.
- However, all people have some innate drive toward novelty; some simply feel it more intensely.
Quote [13:21]:
"Exploring isn't determined by one gene, but there is definitely some genetic underpinning... there's different variants and some people get a bigger kind of jolt out of discovering something new or experiencing something novel than others do." — Alex Hutchinson
Quote [15:57]:
"We're all drawn, I think, to novelty in some way, whether it's listening to new music or finding books that you haven't read, or ordering different things in the restaurant or whatever. Exploring doesn't just mean physical hardship." — Alex Hutchinson
4. How Culture and History Shape National Exploration Tendencies
[15:57–18:57]
- Brett wonders if the American spirit of movement and change is part genetic, a result of selective immigration.
- Alex shares a fascinating study on unusual first names and emigration patterns, suggesting novelty preference may have shaped populations and cultures through self-selection.
5. Predictive Processing: The Brain’s Need for Exploration
[18:57–25:07]
- The dominant theory in neuroscience now sees the brain as a "prediction machine," constantly trying to reduce uncertainty.
- Ironically, to reduce global uncertainty, we're wired to seek out what we don't know.
- The Wundt Curve (an upside-down U) shows we like an optimal amount of novelty—too little is boring, too much is overwhelming.
Quote [21:51]:
"We don't like uncertainty because we like not knowing what's going to happen. We like uncertainty because we like learning what's going to happen." — Alex Hutchinson
Quote [22:21]:
"There's this sweet spot of uncertainty, which is really a moving target. It's different between people. It's different over time." — Alex Hutchinson
6. The Explore vs. Exploit Framework
[25:07–34:15]
- Humans (and organizations) are always balancing between exploiting what they know (safe, rewarding) and exploring new options (risky but potentially higher reward).
- Cognitive science reveals that we use heuristics—such as uncertainty-directed exploration or random choice—to handle this complex decision-making.
- Data shows we tend to underinvest in exploration due to the delayed payoff and risk.
Quote [25:48]:
"Exploiting is basically staying on the path you're on... Exploring something is getting off the beaten path where you don't know what the outcome is going to be." — Alex Hutchinson
Quote [32:56]:
"If you're always exploring... you're never going to listen to the same song twice... one of the reasons to seek out new music is to find things you like and then to exploit it, to sit back and listen to this music you've discovered that you like." — Alex Hutchinson
7. Why We Explore More When We’re Young—and Why That Changes
[34:15–37:39]
- Young people are mathematically "smart" to explore more—more time ahead to benefit from discoveries.
- Alison Gopnik’s theory: Childhood exists largely as an evolutionary solution to the explore/exploit dilemma.
- But in modern life, a purely exploit-oriented older age can be unfulfilling—lifespans are longer, so continued exploration is psychologically healthy and rewarding.
Quote [35:29]:
"I hate that idea. ... I hope that when I'm 75 or 80 or whatever, I still will enjoy the feeling of discovering something new... instead of just doing the same things over and over again." — Alex Hutchinson
8. Practical Exploration: How to Add Exploration to Everyday Life
[37:39–52:57]
- You don’t need to cross oceans—novelty can be found near home, in hobbies, or daily routines.
- Alex's example: exploring his own neighborhood via kayak, discovering new perspectives.
- Advice: Ensure something in your life is new, with outcomes you can't fully predict. It should trigger a bit of nervous excitement.
Quote [52:57]:
"There should be something going on in your life... where you don't know how it's going to turn out... where it's not all mapped out and maybe even makes you a little bit scared." — Alex Hutchinson
9. The Science of Navigating and Cognitive Maps
[39:05–46:23]
- Our brains have place cells and boundary cells to map physical space; modern GPS diminishes reliance on these cognitive maps, favoring stimulus-response navigation.
- The hippocampus, key for mapping, atrophies if underused—reliance on technology could have broader cognitive costs (e.g., for idea-mapping, creativity).
Quote [41:53]:
"The more you use stimulus response navigation, the more you use your caudate nucleus... the less you use your hippocampus, the smaller it gets. Smaller hippocampus is a risk factor for a whole bunch of pretty unpleasant things." — Alex Hutchinson
Advice [45:05]:
"Be present, look around, know where you are... be aware of my surroundings. I'm willing to get lost occasionally willing to take a wrong turn because that will force you to pay your attention, to start forming cognitive maps." — Alex Hutchinson
10. The Role of Difficulty and Discomfort (“Effort Paradox”)
[46:35–50:53]
- Meaning is often found not in spite of difficulty, but because of it—the 'effort paradox'.
- Research (e.g., the IKEA effect) shows we value things more when we struggle for them.
- In exploration, failure or discomfort is a feature, not a bug.
Quote [47:26]:
"There are things that we value not in spite of the fact that they're hard, but because they're hard." — Alex Hutchinson

Actionable Takeaways
- Mix exploration with exploitation: Balance safety and novelty.
- Seek the 'adjacent possible': Don’t just settle—branch out a step from what you know.
- Embrace manageable uncertainty: The sweet spot is not too boring, not too overwhelming.
- Keep exploring as you age: The "logical" end to exploration is not inevitable; keep pushing your boundaries for a richer, more meaningful life.
- Exercise your “navigational” brain: Try orienteering, occasionally forgo GPS, or simply pay more attention to your physical and intellectual surroundings.
