Book review: Range

In many parts of society, we ask people to specialize early and go very deep. This is the path to excellence. In Range: why generalists triumph in a specialized world, David Epstein examines the role breadth plays. I should admit my bias up front: I am definitely a width person, not a depth person. So maybe I just agreed with this book because it reinforced the story I tell myself about my success.

But I do think there’s something to this. Throughout my career, I’ve found that the best colleagues are the ones who have academic or work experience outside of the tech industry. It’s not that they’re necessarily better technically, but they grasp the context much more easily. That becomes increasingly important when dealing with novel and poorly-defined problems.

I’ve long understood the value of coursework outside one’s major. Range helped me understand why that value exists. I sometimes heard at my alma mater that “we have a liberal arts school so we can produce well-rounded engineers.” Now I think perhaps we should have fewer major courses and more gen ed courses. (In addition to ethics classes which should be added to all curricula for separate reasons.)

In the context of the current time, with conspiracy theories enjoying a disturbing degree of acceptance, I find Epstein’s emphasis on amateurs a little concerning. Yes, novices sometimes make discoveries that elude the experts. Still, we must be careful not to replace “appeal to authority” with “appeal to lack of authority”.

I didn’t find Epstein’s writing style particularly compelling. This surprised me since he’s a journalist. I suppose books are a different beast. But the arguments were well-reasoned and supported by research. I would recommend this book to anyone thinking about their future career or seeking reinforcement of their past, seemingly-odd, changes in direction.
