The book is roughly divided into 3 parts. Part one is crammed with interesting factoids, optical illusions and scientific studies that answer questions such as…. how blind people can “see”, why a normal person cant tickle themselves but schizophrenics can, what synaesthesia is and what time of the month strippers will make the most money. I absolutely loved this section as I never seem to be able to get enough of arbitrary and strange facts.

Part two focused more on the psychological part of how decisions shape us, even if we seemingly unaware of the process. It also brings up the subject of blameworthiness, and specifically focused on criminals and current ways of incarceration. Even though I may not entirely agree with what was presented in this section it does make you think about the justice system in a different way.

The last part of the book reverts back to the biological side covering the cause and effect of changes in the brain’s chemistry (through medication, narcotics or alcohol etc).
This is at heart a scientific book but explained in a way that is easily digestible.
