Perfectly irrational

the unexpected ways we defy logic at work and at home

by Dan Ariely

Published 2010334 pagesISBN 978-0-0619-9503-3

How can confusing directions actually help us? Why can large bonuses make CEOs less productive? Why is there such a big difference between what we think will make us happy and what really makes us happy? In his groundbreaking book Predictably Irrational, social scientist Dan Ariely revealed the multiple biases that lead us into making unwise decisions. Now, in The Upside of Irrationality, he exposes the surprising negative and positive effects irrationality can have on our lives. Focusing on our behaviors at work and in relationships, he offers new insights about how one unwise action can become a long-term habit, how we learn to love the ones we're with, and more. From our office attitudes, to our romantic relationships, to our search for purpose in life, Ariely explains how to break through our negative patterns of thought and behavior to make better decisions.--From publisher description.

Beyond its central premise, the book can be read through the connected lenses of Fiction, Nonfiction, Mental Health. Those themes offer useful points of attention as the characters, ideas, or world develop, especially where the book complicates the expectations of its primary category.

A more thoughtful way into this book

This guide uses the edition details and category signals above to help you choose deliberately. It does not replace the author's work or a full review.

Good to know

A comfortable full-length choice for steady daily reading.

Begin with its place in Fiction, then notice where the book resists that label.

Try this reading approach

Read for connection, not completion.

Mark one passage that sharpens the book's central concern and one that complicates it. That tension often reveals more than a quick summary.

Three questions to carry with you

  1. What does the central character want, and what do they misunderstand about that desire?
  2. Which detail or relationship changes how you interpret the story?
  3. What feeling or question does the book leave with you after the plot moves on?
