I think this book had potential, but overall it just wasn’t for me.

I felt it was very heavy and a tad optioned and swayed.

This book was absolutely fascinating! I love how Dr. Guy Leschziner takes the seven deadly sins and then takes research into neurology and human behaviour to find biological functions that meet or create a use for these sins for humanity to survive.

This book had me thinking this book had me questioning - neuroscience and psychology have never been as relatable and linked to behavior, as well as this in my opinion.

I personally am not a scientist and neither fields are my specialty, but this book was easy to listen to and very captivating.

Dr. Guy Leschziner himself does an excellent job narrating his own book. His reading is very relatable and he does a good job connect connecting to the reader.

This was an excellent audiobook. I highly recommend it to anyone who has a interest in in the connections between human behaviour and the seven deadly sins.

I love reading about the seven deadly sins and I love science/scientific writing, but there was something about combining the two which made it all less exciting to me. I did enjoy the book, and learning about new disorders/medical cases that could be associated with each of the sins, but it wasn't exactly what I was expecting to read. I think overall I enjoyed the book, and I'm glad that I finished it though. One thing that irritated me about the narrator was the pronunciation of the word sloth! Every time he said it I cringed a little bit.

This is a fascinating look at human behavior and psychology using each of the seven deadly sins as a universal theme and taboo

I read the book and listened to the audio book. Both were very good.

I enjoyed how the author organized the information. We took a look at each of the "Deadly Sins" and dove into the biological and psychological reasons humans partake in these behaviors. The book highlights the science behind the behavior and highlights that avoiding these "sins" may be more difficult for some than others. Explaining the chemical imbalances in the brain that may cause someone to feel more tired leads to sloth or how a person who has been exposed to violence is more likely to become violent helps create understanding. Though the course of the book the reader can see each of the "sins" from a cultural norm perspective then digs into the "why" behind it. Fascinating read when learning about the causes for human behavior.

Non-fiction isn't my go to genre but I devoured this audio book within a day! Dr Guy Leschziner walks through real life examples of his patients, correlations to the deadly sins, and explanations on how DNA / Brain Trauma shapes our behaviors.

Each chapter represents a different deadly sin with several patient stories. My favorite chapters were wrath, gluttony, lust, and pride.

In wrath, one of the examples Dr. Leschziner covers how much testosterone an embryo is exposed to in the womb can help predict how an individual processes and responds to anger. (There's also a coloration of the size of your index vs ring finger to determine testosterone exposure).

Gluttony there is a story of a patient whose DNA strain causes her brain not to recognize satiety which ultimately leads to her death.

One story we follow in lust shows a soldier with brain trauma to the hypothalamus and how it influenced his sexual appetites.


The audiobook started off a little monotone but once we got past the introduction chapters I was locked in! I would recommend this to anyone who loves psychology and the age old question, nature vs nurture?
