WHAT'S THE BOOK ABOUT?

On their way from the lab to your news feed, psychology ideas evolve.

Every day, you encounter claims about how your mind works, backed by the phrase "studies show."

It takes 21 days to form a habit. You have a love language. Power poses can change your hormones. Your attachment style shapes your relationships. Dopamine is your brain's pleasure chemical.

Some of these ideas are supported by evidence. Some are oversimplified. Some were never backed by research in the first place. The problem is, it all sounds convincing.

When Studies Become Stories examines 89 of the most widely shared ideas in popular psychology and gives each one a straight verdict:

Has Evidence
Overstated
Oversimplified
No Evidence

Covering topics including relationships, memory, learning, personality, motivation, decision-making, trauma, emotions, and the brain, it explains what the studies actually show, where the popular version goes wrong, and what a more accurate version looks like.

Written in easy-to-digest, accessible language, this is psychology in plain terms. When you finish reading this book, you will be able to:

If you have ever heard a psychology "fact" and wondered whether it was actually true, this book is for you.

Includes bonus content covering popular claims about sex, pornography, fetish, and kink - discover what the studies say on these topics today.

REVIEWS

What readers are saying

"The clarity of the book's prose shines throughout. Social science is often cluttered with technical terminology, competing definitions, and methodological caveats, yet Mack has an impressive ability to translate these complex debates into accessible language while preserving nuance."
— Independent Book Review
"When Studies Become Stories" by Nina Mack is very well written. It is based on the author's decades of experience in psychology. The book presents, contextualizes, and outright debunks nearly 90 popular myths and misconceptions about psychology. [...] each page is packed with interesting true and accurate facts about psychological myths and the actual facts. Best of all, you can read the book in five minute blocks, one "myth" explained and even debunked at a time. This makes it perfect for waiting rooms or casual reading spaces like the living room.
— ARC Reviewer
"I have a keen interest in psychology, but I'm a layperson, so I appreciated how accessible this book was. I enjoyed learning about these psychology ideas; some were familiar, but many were completely new to me. I think this is the type of book I would return to. There is also a glossary of terms at the back, which I found very useful."
— NetGalley ARC Reviewer
"This a must read for anyone who gets pulled into social media content about current psychology! It was so eye opening!! Highly recommend."
— NetGalley ARC Reviewer
"This is one of those books that quietly becomes a permanent resource on your shelf. What impressed me most was the structure. The author explains the framework at the beginning and then sticks to it consistently throughout the entire book. Each chapter examines a popular psychology concept, model, or belief and places it into a clear category based on the available evidence [...] This simple approach makes the book incredibly accessible. I read it in small chunks between work, cooking, playground visits, and bedtime routines, and it was remarkably easy to pick up again without feeling lost."
— NetGalley ARC Reviewer
"For anyone working in coaching, education, psychology, or simply interested in human behavior, the categorization alone is immensely valuable [...] What I appreciated most was the nuance. The author doesn't simply dismiss ideas or declare them "right" or "wrong". Instead, each concept is carefully examined and placed into context, allowing readers to understand both its strengths and limitations. If you enjoy psychology but also care about evidence and scientific accuracy, this is a fantastic resource. Less sensationalism, more critical thinking and that is something I always appreciate. A highly useful and thoughtfully structured read that I know I will return to again."
— NetGalley ARC Reviewer
"I really like the concept of the book and I would very much like to read a similar analysis about other fields, from medicine to nutrition to anything else really."
— Advanced reviewer
