Regarding Kahneman, keep in mind that in the following years there has been a lot of doubt - including by Kahneman himself - about the scientific validity of the evidence.
I can really recommend The Kingkiller Chronicle.
It is an outstanding piece of fantasy. The way of magic is developed / presented in a way you really can feel how it could be possible. A great piece of art by Patrick Rothfuss.
The last book (of three) is currently in the making. I am really looking forward to read the first two books again once the last part is published. I want to know more about The Doors of Stone - now! :-)
