Alex Hutchinson is a science journalist, former physicist, and an author. Why are humans wired to explore? We’re naturally drawn to the unknown, but that curiosity can sometimes lead us off course. So how do you design a life that channels exploration and dopamine in the right direction without going too far? Expect to learn why humans are drawn to explore and what the neuroscience behind exploration does to us in, the truth as BS behind dopamine and how to design your life to maximize dopamine, how uncertainty plays into our drive to explore, if curiosity and exploration are the same, the importance of play, what separates the elite athletes compared to the average person in terms of mental capabilities, and much more… Sponsors: See discounts for all the products I use and recommend: https://chriswillx.com/deals Get the Whoop 4.0 for free and get your first month for free at https://join.whoop.com/modernwisdom Get $350 off the Pod 4 Ultra at https://eightsleep.com/modernwisdom Get a 20% discount on Nomatic’s amazing luggage at https://nomatic.com/modernwisdom Extra Stuff: Get my free reading list of 100 books to read before you die: https://chriswillx.com/books Try my productivity energy drink Neutonic: https://neutonic.com/modernwisdom Episodes You Might Enjoy: #577 - David Goggins - This Is How To Master Your Life: https://tinyurl.com/43hv6y59 #712 - Dr Jordan Peterson - How To Destroy Your Negative Beliefs: https://tinyurl.com/2rtz7avf #700 - Dr Andrew Huberman - The Secret Tools To Hack Your Brain: https://tinyurl.com/3ccn5vkp - Get In Touch: Instagram: https://www.instagram.com/chriswillx Twitter: https://www.twitter.com/chriswillx YouTube: https://www.youtube.com/modernwisdompodcast Email: https://chriswillx.com/contact - Learn more about your ad choices.

Chapter 1: Why are humans drawn to explore?
I think the biggest, um, The misconception, let's say, about dopamine is that it's like the pleasure chemical, that it's what you get when you feel good. In fact, this has been known for 20 or 30 years that it's actually – you don't get a hit of dopamine, again, when something is good. You get something when it's better than expected. So it's about expectation.
So it's about wanting something more than having it. The pleasure of having something, that's like endogenous morphine, basically, endorphins. The pleasure of wanting something, dopamine is related to that. But the brain repurposes the same channels for different communication.
I'll be honest, I had hoped to have the definitive theory of dopamine like, people, I'm going to tell you what dopamine does. Here it is. Here's the truth. Here's the myth. And my impression after spending an awful lot of time talking to scientists and reading the papers is that even scientists aren't entirely sure the full story of dopamine right now.
So the message I would hope people would take away is it's not just a pleasure chemical and that the dopamine fasting idea, you know, the idea that, oh, we get too much dopamine in society today. It's one of those things where I think the scientific underpinnings of that are not solid.
It doesn't mean I think the advice is bad to actually try and maybe not always be the rat pressing the button saying, give me more, give me more, give me more. But dopamine is a lot harder to pin down than that.
How can people design their lives so that they use dopamine more effectively or so that they can get more dopamine without having to do something insanely extreme or get addicted to meth?
Yeah, which is always a good plan. I think... I would go back to that distinction I made before between exploring can lead you to learn about the world and exploring can make you feel good. And I would say the dopamine part, like I think when we talk about dopamine, we're using it as a shorthand for saying, let's do the things that give us a rush that feel good.
And often that's mediated by dopamine. I think it's worth being thoughtful about is this good feeling, does it align with also teaching me about the world or teaching me about myself, taking me in somewhere that's worth going? Or is this just empty calories? Is this the equivalent of just tearing open sugar packets and pouring them down my throat?
Or am I eating an apple, which is giving me some nice sugar, but it's also giving me a bunch of other things that are useful? So I know it's easy to beat up on, you know, like,

Chapter 2: What is the connection between exploration and dopamine?
That's right. If you can see it with your binoculars, you're doing okay.
Okay, cool. Getting back to exploration, did you make any changes to your life after looking at this book? How's this netted out practically? Yeah.
So there's the vague big picture things, but I'll give you a concrete practical thing, which is that I do my best not to turn on the turn-by-turn directions in my car when I'm going out or even on my phone when I'm going for a walk. This is for a couple of reasons. One is that it's like, okay, like...
I'd like to be a little more present in my environment and be looking out the window instead of looking at my screen. But actually, in the book, I spoke to some neuroscientists who are actually concerned about this, who are actually concerned that just as London cab drivers have enlarged hippocampus because they've learned so much about their environment, people who
use what's known as stimulus response navigation, that is, who just follow, like, turn left here, turn right there, turn left. And we can do that with or without GPS. Their hippocampus is, they're not using their hippocampus. They're using a different part of the brain called the caudate nucleus. And that actually translates into difference.
Your hippocampus gets smaller and your caudate nucleus gets bigger. And this over life, when we're kids, we're all hippocampus. We don't know our way around the world. So we're cognitive mapping everywhere we go, trying to figure out where we are. As we get older, we learn to use this stimulus response approach because it's faster. It's more efficient. It's less prone to errors, right?
But the problem is, as the world gets more and more optimized, as I can get into my car and just press a button and I never even have to know my own neighborhood, then we're not using our hippocampuses as much. And that leads them to being smaller. And there is research. And it's a chain of logic that isn't... Nobody has shown that turning on your GPS is going to make you get dementia.
But there is a chain of logic that... People who rely most on stimulus response navigation have smaller hippocampus. People who have smaller hippocampuses, that is a known risk factor of conditions like Alzheimer's, PTSD, depression. So I don't want to oversell that, but I would say even with caveats, my takeaway has been I figure out where I'm going.
I look at the directions I try and figure out, understand where I'm going. And then I turn it off until I need it. So I don't use the turn button directions. And that means I get lost sometimes. And that means I have my kids chirping me from the backseat saying like, mommy uses Waze. Mommy wouldn't have missed that turn. Why don't you use Waze?

Chapter 3: How can exploration lead to better outcomes?
yeah everyone needs to follow you on twitter at sweat science it's you know if you like evidence-based exercise stuff you're awesome and uh new book why should people go and get it well they should explore the topic of exploring i i hope it'll you know there's no magic formula but i hope it'll encourage people to to find spaces in their life to uh to be surprised sick alex i appreciate you thanks so much chris
