Johann Hari is definitely a crank. I like him already! He wrote a book about drugs and addiction called Chasing the Scream, and there was a famous TED talk he did about that. I haven’t read Chasing the Scream, but this evening I am going to read Stolen Focus: Why You Can’t Pay Attention and How to Think Deeply Again.
Note: the links to Amazon above are affiliate links. I recently signed up for an affiliate account with Amazon. Is that cool? Is that not cool at all? What sort of disclosures are appropriate when you use affiliate links? I have never used them before and am not expecting to make any significant amount of money with them, so maybe I should just not use affiliate links at all? I dunno. Would be happy to hear from you if you have an opinion.
