Feedback control of computing systems Book

I didn't like this book, but two of my friends really did (and we are very similar in our parenting styles and our enjoyment of this sort of non-fiction).

My problem with this book was that it constantly used direct quotes from girls as evidence. The quotes were presented as examples that represented the cohort, however I just never really believed it. Many times the quotes, while showing the young person's view, did not really reflect what was really happening. I don't mean to devalue the opinion of the young person, I only mean to suggest that being in the middle of a problem does not necessarily make you the expert on it.

Too often the book cut to a quote in order to prove a point. It didn't work for me. I would have preferred if the an explanation of the quote was given... ie We asked 25 girls the same question and 19 gave us similar answers.

Surely it is naive to believe that every girl had the exact same response... so why do I feel the quotes were selected that suited the needs of the book, rather then representing the cohort.
