Alchemy: The Surprising Power of Ideas That Don't Make Sense by Rory Sutherland

5.0

Incredible book, that uses psychologic as opposed to a pure data-driven approach. Includes some psychological themes of:

Minimising downside risk
Decoy effects to have a comparison point to anchor too
Signaling
Status driven behavior (Swapping gold for iron in Spain for a war effort with a stamp saying you swapped gold for iron)

Alchemy also claims we've solved a lot of the simple logical problems, and are hence left with an oversized number of psychological problems. Interesting.
