The Efficiency Paradox by Edward Tenner

I knew I had to read this book once I saw it because the title is too good to resist. Plus everyone is generally so positive about big data I was quite interested to see some criticism of it.

First, a definition of efficiency. The author defines it as “producing goods, providing services or information, or processing transactions with a minimum of waste”. The book basically goes through the history of the idea of efficiency and then goes on to discuss specific examples: the internet and democratisation of information, teaching, GPS, and medicine.

The way I see it, the entire argument can be summed into: automating things can be inefficient because innovation requires serendipity (which algorithms cannot provide). In other words, innovation requires inefficiency, i.e. ‘wasted’ or failed ideas.

To be honest, I’m not entirely convinced by some of the arguments. I can see how innovation may require ‘waste’, but for specific examples like GPS, it may be that we don’t have enough information to for the algorithms to be useful. Same for teaching - the bigger the database, the easier it is for lessons to be customised for the student.

And for some things, like medicine, I feel that the argument took the wrong direction: the author argues that automated note-taking doesn’t make things more efficient as doctors still spend a lot of time on the computer, but the author doesn’t discuss how the shared information may make the process more efficient if the patient moves between departments. So I felt this was more of a misdirected argument (and not that relevant to the central premise).

Another example would be the argument about ‘waylosing’ (finding something unexpected when you get lost). I agree that it does have benefits, but I don’t think that ‘the inefficient wanderer, on the other hand, will be using his or her time more efficiently by discovering what is less documented, or even undocumented.’ That really depends on your aim in travelling - to learn something new or to get from point A to point B.

Overall, I thought that the book was interesting, but it didn’t really fulfil the ‘promise’ of telling me the limitations of big data. Instead, the arguments in the book talk more about how we’re misusing the platform innovations, which is interesting but not quite the point. Perhaps these are the ‘limitations’ that the subtitle was talking about, but there really should be a clearer line between the limitations and the purpose of each technology.

  1. This book sounds interesting. I can think of many ways the agency I work for could be more efficient and still maintain quality performance and customer service. I know the county over has talked about going automated because they are so much bigger than we are, but I think it would do a disservice more than it would help. We rely so much on computers and yet still create so much paper waste still. So much for going paperless . . . Haha

    1. Yes - in some ways the movement to go paperless has only created more paperwork :p
