Ergodicity: Definition, Examples, And Implications, As Simple As Possible

Ergodicity: Definition, Examples, And Implications, As Simple As Possible

By  Luca Dellanna

Some reviews of Luca’s previous books

“This book is like a magnificent suspension bridge, linking the science of the human brain to the practical craft of applying it in everyday life. I loved it.” – Rory Sutherland, Ogilvy’s Vice Chairman

So insightful with common sense applications of Complexity and the ability to communicate clearly!!” – Bob Klapetzky.

A SUPERB book […] by one of the profound thinkers in our field [behavioral economics].” – Michal G. Bartlett

What’s ergodicity, and why it matters?

“The Most Important Property to Understand in Probability, in Life, in Anything.” – Nassim Nicholas Taleb on ergodicity.

“I think the most under-rated idea is ergodicity.” – David Perell, author.

Is ergodicity the most important concept in decision-making and behavioral sciences? (Yes.)

Is it relevant for you in your daily life? (Yes.)

Is it possible to explain it so simply that a grandma or a high-schooler can understand it? (Yes.)

Even if they know nothing about maths? (Yes.)

That’s because ergodicity is an important idea with so many practical applications. Sadly, most books describe it in a very technical way, making it inaccessible to most people.
In this short book, 6-times author Luca Dellanna describes ergodicity as simply as possible. You will read stories about how not knowing about it destroyed his cousin’s career as a skier, or how misunderstanding it caused additional deaths during the pandemic. You will learn how to spot situations in which ergodicity matters and the three strategies to react appropriately.

This book is shorter than other books by the same author (about 80 pages of content, hence the reduced price).

This page sells the eBook / Kindle version. Around mid-November, the paperback version will become available on Amazon and in selected stores (e.g., most Barnes & Noble).

There will be no discount after launch, and the paperback version will be more expensive than the digital one.

Who is this book for?

This book is for readers interested in growing themselves, their career, or their business, and who want to learn about ergodicity and its practical applications without having to understand its mathematical foundation. No mathematical knowledge is required, only a high-school level understanding of English.

Readers who want to master the theory and mathematical foundation of ergodicity are better off reading a more formal manuscript. This book is not a substitute for it, but a complement.
