I have not read the book, but the review in New Scientist (26 Nov 08) did not over-excite me.
“His basic theme is that success depends on relentless application and a supportive environment, not merely rare "natural" talent or intelligence”
There is casual use of statistics – “crashes happen far more often when the captain, rather than the co-pilot, is flying the aircraft” – apparently without balanced explanation for the reasons why.
Similarly, the reference to ‘power distance’ without consideration of other factors might indicate a superficial (cheap) use of incidents from a high profile industry to further his book.
IMHO, his previous work – Blink – was biased; it is unlikely that a writer prone to bias could discuss the aspects of CRM - human behavior – in aviation with any authority.
