Our brain is not infallible, not at all. In fact, it often leads us, without us even realizing it, to wrong assessments and bad decisions in our professional or personal life.

In this unique book, which is now read by millions of readers all over the world, Rolf Dobelli teaches us, in 52 short texts with clever examples, to identify and avoid "cognitive traps", those traps of the mind that we all risk falling into at any moment.

- Why do we systematically overestimate our abilities and knowledge?
- Why do we always say "yes" to likeable people?
- Why do we prefer to have a wrong city map rather than no map at all?

It is a fact: understanding how and how easily we can be deceived gives us a clear advantage over others...

"Dobelli combines imagination and realism, a combination that we have not seen since the wise men of the Renaissance."
(Nassim Taleb, author of The Black Swan)
