The Halo Effect

My overall thoughts before reading my notes:
It all makes sense. The examples on the errors people make when reasoning about business success or failure are quite real. But after reading the book, I still don’t know how to avoid those delusions, apart from being aware that they exist, which I did before reading the books. It was nice to have them listed out I guess, but that’s as useful as the book gets.


  • People like stories when it comes to business success. It is intuitive. But maybe we need numbers to actually explain success. It is still unclear how to apply science, and maybe science is not the best solution here in business success because there is no controlled experiment.
