This book is a great introduction to the subject of Intelligence and psychometrics! I just completed the book in two days and must say it was very insightful and straight to the point. It wasn't the easiest reading but far more straightforward than most psychology/sociology stuff I have come across. I knew very little about psychometrics before reading this book as I majored in accounting and got my MBA, with an emphasis in finance. Plus I have some engineering. I say this to put it into perspective as psychology, sociology, philosophy haven't been easy for me to comprehend in the past as they have been too verbose for me and boring, as it is out of my primary field of interest. But, I was very happy to read this book and learned a lot in a short matter of time. Additionally, if you want to learn more the author points to additional books/articles on each topic discussed. This book is great for the following reasons:
1) It is easy to read as it is written to the non psychiatrist.
2) It has a section explaining the only technical stuff used, which is statistics (used in studies outside of psychology too.)
3) It provides a synopsis of the top issues, studies, articles and conclusions written about intelligence.
In my opinion, the author of this book is very fair and reasonable as he consistently stated both sides of an argument if there was one to an issue. He did provide his insights only after stating what the majority of his fellow associates had concluded as well as if the debate was largely over or not within each issue.
So what was talked about in this tiny book of 125 pages?
1) Is there a general factor in intelligence?
2) Are there multiple types of intelligence, as Howard Gardner thinks?
3) Are people getting smarter?
4) How does race, age or the environment you are raised in affect intelligence?
5) What is the 'Flynn effect'?
6) How do our brains work?
Basically, Deary convinced me that there is a general factor that accounts for one's mental abilities but, as he states, there is still much research to be done as to how the brain operates so that improvements can occur in testing/research and cures for horrible diseases, such as Alzheimers, can be figured out.
