Perhaps it's the author's intent to make the book as concise but informative as possible that it became a highly concentrated dose of investment psychology and empirical stuff not easily digestable for rookies or even veterans without a strong academic background on finance. For example, he had covered in the 28 page first chapter, psychology theories (with source reference, and simple background/statistics info/support) including over-confidence, over-optimissim, cognitive dissonance, confirmation bias, conservatism bias, anchoring, representativeness heuristic, availability bias, ambiguity aversion, frame dependence/mental accounting, utility theory (dynamic) prospect theory etc. Do you get what I mean?
IMHO, this book can serve as a recap for advanced traders who understand well basic financial concepts including Efficient Market Hypothesis and it's offsprings like CAPM, and can read statistics and essays with ease. For novices, "Beyond Greed and Fear: Understanding Behavioral Finance and the Psychology of Investing" by Hersh Shefrin and "The psychology of Finance by Lars Tvede" should be better choices.
p.s. The conclusions in the end of each chapter are well written, I must add. However, I cant say there are significant correlation between individual chapters.
