15 Best Books on Human Nature

I've been keeping a Great Books List for over five years now. It's based on the last 12 years of reading — over 500 nonfiction books recommended by thought leaders and exceptional individuals I admire. I've read all of them and compiled the best into categories.

This is the Human Nature, Behavior & Psychology category — the books that answer the question that got me into reading in the first place: why do people do the things they do?

From evolutionary psychology and neuroscience to existential philosophy and the dark corners of persuasion — these 15 books are the ones that actually moved the needle for me. If you want to understand what makes us tick, start here.

1. The Denial of Death

Ernest Becker · Pulitzer Prize 1974

We all know we're going to die someday — a predicament unique to the human animal. But what kind of psychological implications does that terrible knowledge have?

This book had a profound impact on me. It was quite early in my reading journey and it got me to read Kierkegaard, Nietzsche, and a lot of other thinkers that shaped my development. It's not the easiest read, but it's a great book that will add tons of new titles to your reading list.

📖 Read if you want to trigger an existential crisis, love the big questions, and aren't afraid of adding books to your list.

2. Determined

Robert M. Sapolsky · Named Best Book of the Year by The Washington Post & WSJ

This book is the conclusion of Sapolsky's life work in biology, and it comes to the natural conclusion that free will is just an illusion. He breaks down why it can't possibly be that we humans have any kind of free will.

It's a challenging read — but you should read challenging books because it's like going to the gym for the brain. I love books that combine a lifetime of experiments and research, and we get all the conclusions for 20 bucks.

📖 Read if you're interested in human behavior and don't shy away from books that challenge everything you think you know.

3. Man's Search for Meaning

Viktor E. Frankl

One of the big classics. It's a thin book and everyone should read it at least once. Frankl was a Holocaust survivor and psychologist, and in this book he describes life in the concentration camps.

It's often at the extremes — the extreme of human suffering and extreme evil — that we can most clearly see what's important in life. The lessons from this book have had an impact on millions of people. If there is one book on this list you should read, even if you're not an experienced reader, pick this one up.

📖 Read if you want a short, gripping book that will change your life — and show you how to stay human in an inhuman situation.

4. Flow

Mihaly Csikszentmihalyi

The more time you spend in flow — that state of enough challenge to not be bored, where time ceases to exist, where you feel light and creative — the more fulfilling your life will be. This is the psychology of optimal experience.

Learning how you can get more flow states out of your everyday life — at work, with your family, in your spare time — the better life you will have.

📖 Read if you feel stuck and frustrated in everyday life, want to increase your baseline happiness, or are curious about the ingredients for a good life.

5. The Laws of Human Nature

Robert Greene

This is my number one pick if you want to learn about why people act like they do — both the good stuff and the bad stuff. Greene is a master of dark psychology and has written The 48 Laws of Power, The Art of Seduction, and Mastery.

This book is his magnum opus. Even if you're a new reader and it's thick, it's one of the most accessible ways to look into human psychology. It will also put a lot of new books on your reading list, because he cites so many sources.

📖 Read if you want to know why people act the way they do — and want a library of further reading recommendations.

6. Thinking, Fast and Slow

Daniel Kahneman · Nobel Prize in Economics

A landmark book and a great one for anyone who thinks they are a rational person — it will show you that you're probably not. You'll learn about heuristics and cognitive biases in a way that sticks.

Not the easiest book to read, but probably one where you get more value than from reading 10 other books combined.

📖 Read if you think you're rational (spoiler: you're not) and want to understand the shortcuts your brain takes every day.

7. The True Believer

Eric Hoffer

Thoughts on the nature of mass movements. Eric Hoffer explores the temptation to submission in authoritarian regimes — a landmark book. If you want to understand why people want to escape from freedom and are pulled towards authoritarian systems, this is the one.

It's one of those books I finished and then started reading again immediately. That good.

📖 Read if you want to find out what makes humans tick — even when they tick in a perverse fashion.

8. The Righteous Mind

Jonathan Haidt

Why good people are divided by politics and religion. The Righteous Mind brings challenging topics to the table about morality, politics, and religion — and shines a light on the miracle that humans are able to cooperate at all, and why we often fail.

If you have a book club, this is the one to read — it will spawn amazing discussion. Most of these books are available as audiobooks too, which is how I manage to plow through so many with small children and a daytime job.

📖 Read if you want to know why politics divides us, want to explore the moral landscape, or are curious about the evolutionary advantage of religion.

9. Behave

Robert M. Sapolsky

A majestic account of human behavior by renowned Stanford professor Robert Sapolsky. He takes you through what happens in the brain one second before a behavior, then one minute before, then hours, days, and all the way back to our evolutionary past.

It's a highly complex and nuanced read — a companion piece to Determined — but equally rewarding. If you want the full picture of why humans do what they do, from neurons to culture, this is the book.

📖 Read if you want a deep, scientific understanding of human behavior and don't shy away from challenging books.

📚 Get on Amazon

10. The Selfish Gene

Richard Dawkins

The book that introduced the concept of the "meme" and changed how we think about evolution. Dawkins argues that natural selection operates at the level of genes, not individuals or species — and that reframes everything about human behavior.

It's beautifully written popular science that will give you a completely new lens for understanding cooperation, altruism, and competition in human nature.

📖 Read if you want to understand the evolutionary logic behind human behavior — from selfishness to surprising acts of kindness.

📚 Get on Amazon

11. The Better Angels of Our Nature

Steven Pinker

Pinker makes the case that, despite what the news tells you, violence has declined dramatically over the course of human history. He traces this arc from tribal warfare to the present day and examines the psychological forces — empathy, reason, self-control — that have driven us toward peace.

It's a big book, but it's one that fundamentally changed my outlook. If you think the world is getting worse, read this first.

📖 Read if you want a data-driven, optimistic view of human nature and the forces that make us less violent over time.

📚 Get on Amazon

12. The Moral Animal

Robert Wright

Evolutionary psychology applied to everyday life — jealousy, love, status, morality. Wright uses Darwin's own life as a case study to explore how natural selection shaped our social instincts and moral intuitions.

If you read The Selfish Gene and want to go deeper into what evolution means for human social behavior, this is the natural next step.

📖 Read if you want to understand the evolutionary roots of love, jealousy, status, and morality.

13. The Third Chimpanzee

Jared Diamond

We share 98.4% of our DNA with chimpanzees — so what makes us different? Diamond explores the rise of humans from just another great ape to a species that creates art, wages genocide, and destroys its environment.

A fascinating and humbling look at what makes humans unique — and what doesn't. It's the book that launched Diamond's career and paved the way for Guns, Germs, and Steel.

📖 Read if you want to understand what separates humans from other animals — and what really doesn't.

📚 Get on Amazon

14. Notes From Underground

Fyodor Dostoevsky

This book took me by surprise. Again I'm reminded that classics are classics for a reason. This short novel is more deeply psychological than most of my psychology books — a bitter, brilliant monologue from a man at war with himself and the world.

If you have any interest at all in understanding human nature, this should jump to the top of your reading list. It's Dostoevsky at his most raw and most human.

📖 Read if you want a Russian classic that is NOT 1,000 pages long — one that makes you think about the irrational side of human nature.

📚 Get on Amazon

15. Influence: The Psychology of Persuasion

Robert Cialdini

The classic guide to understanding the psychology behind why people say yes. Cialdini breaks down six universal principles of persuasion that drive human behavior — reciprocity, commitment, social proof, authority, liking, and scarcity.

Essential reading for anyone who wants to understand how we're wired to be influenced — and how to protect yourself from manipulation.

📖 Read if you want to understand why you buy things you don't need and the hidden forces behind human decisions.

📚 Get on Amazon

These are books that made my life more enjoyable, that piqued my interest, that transformed my way of thinking. I hope you found something here you want to pick up and read.
