I think even the publishers suggest a title thats best suited for the content too, and the author still gets the final say. I too am skeptical when it comes to so-called “hacks” in general but I’m happy to try this one out.
My opinion about that is deeply influenced by a professor I used to have. Once he spent one lecture just reading a brilliant essay by a British judge. He did not read it, he performed it, slowly, carefully, and it was the best lecture I ever had. And his advice was: "read slowly, or you might as well not read at all, forget the 'hacks', the speed-reading techniques, reading is enjoyment, if you have the right material, be thankful for every second, savor it", and if only I could have taken his advice more seriously at the time. I do now though.
