I have to admit, I was a bit dismayed by history professor Jerry Z. Muller's new book The Tyranny of Metrics. A big believer in using numbers for analysis, I didn't like seeing such a solid argument for why we should be more careful before deploying metrics to improve organisation performance.
At fewer than 200 short pages, the book is an admirably easy read. If I were to add anything, that would be a discussion on the effective altruism movement in the chapter on philanthropy and foreign aid.
All in all a great read.
