I'm currently listening to the audiobook of Nudge by Richard Thaler and Cass Sunstein.
It's a fascinating and fun book that looks at the poor choices we tend to make in all sorts of everyday decisions, often because we are influenced by natural biases, misconceptions and inertia.
The authors suggest that these behaviours are simply part of being human. However, they go on to demonstrate that by understanding how people think, we can design choice environments (or Nudges) that make it easier for them to choose what is best for themselves, their families, and their society.
I particularly like their concept of "choice architecture" – structuring choices in ways that nudge us in beneficial directions without restricting freedom of choice.
Definitely worth a read/listen.
Find the book at Amazon and the audio at Audible.
Also, listen and watch Richard Thaler talking about Nudge at the RSA.
