Why You Buy That Stuff
Spent: Sex, Evolution, and Consumer Behavior
by Geoffrey Miller
Psychology
TL;DR
This book is basically a savage exposé on how our entire consumer culture is just a giant, elaborate mating ritual. It breaks down how we use our purchases, from cars to coffee, as costly signals to broadcast our genetic fitness, intelligence, social status, and desirability to potential mates and rivals. You'll learn to identify the underlying evolutionary drives behind seemingly irrational spending, understand how brands exploit these instincts, and maybe even figure out how to flex smarter (or at least stop being a total simp to consumerism). It's all about understanding the primal psychology behind why we buy what we buy.
Action Items
Next time you're about to buy something pricey, pause and ask yourself: 'Am I buying this for me, or for the imaginary audience in my head?'
Look at your social media. What 'smart' or 'responsible' signals are you accidentally (or intentionally) sending? Are they even true, or just for show?
Think about your hobbies and interests. Are you genuinely pursuing them, or are some of them just for the 'vibe' you want to project to others?

Key Chapter
Chapter - Your Shopping Cart: A Primal Dating Profile
This chapter totally blew my mind, making me realize that every single thing we buy isn't just about utility; it's a loud, obnoxious billboard for our genes. Think about it: that expensive watch isn't just for telling time, it's screaming 'I'm financially stable and probably have good taste!' The book argues that we're constantly, often unconsciously, using our purchases to signal our fitness, intelligence, and desirability to potential mates and rivals. It's like our entire economy is built on a giant, elaborate mating ritual. Understanding this means you can either play the game smarter, or at least stop feeling so bad about wanting that ridiculously overpriced avocado toast – it's just evolution, baby!
Key Methods and Approaches
The 'Look At My Shiny Feathers' Game
(AKA: Conspicuous Consumption & Signaling)
Description:
We buy stuff not because we need it, but to show off how awesome we are to potential mates or rivals. It's all about the flex.
Explanation:
Imagine society is one giant, chaotic dating app. Every purchase you make is like a profile picture or a bio line, trying to scream, 'I'm a catch!' That fancy car? Not just transport, it's a 'I'm financially stable and probably have good genes' billboard. That designer outfit? 'I have taste and resources.' It's all about flexing your 'mate value' without saying a word, like a peacock showing off its tail feathers, but with a credit card.
Examples:
Buying a ridiculously expensive coffee every day for the 'gram, even if you could make it cheaper at home.
Rocking designer clothes or accessories even if you're low-key broke, just for the clout.
Getting a degree from a prestigious (and expensive) university, even if a cheaper one offers the same education.
Driving a luxury car you can barely afford, just to look successful.
