Christian Morel approaches the subject in a pragmatic way, taking care to illustrate this with examples he describes and comments at length, including an air accident, the explosion of the shuttle Challenger in 1986, the construction of Bridge on the River Kwai or how to design transparent projectable.
According to the author, the absurd decisions have three possible origins:
1) an error of reasoning, a logical flaw
2) a group process which leads to a poor or catastrophic result
3) a radical loss of sense: it then attaches more importance with that goal, which is by the way, one of the classical definitions of stupidity in philosophy.
The strong points of this book are:
1) clarity of writing that, coupled with the absence of jargon, makes entertaining read,
2) use examples that illustrate about suitable manner
3) the approach by the field rather than a theory of the error
