I saw Nguyen, a philosophy professor, on Pablo Torre Finds Out and his work sounded interesting, so I gave it a gander. And it is interesting.
At the heart of this book lay this cunundrum: both games people play for fun, and performance metrics that guide much of our lives are based on clear rules and fixed guidelines - but people (including Nguyen) find the former to be joyful and enriching to one's soul, while the latter often are horrible and drain away your soul. How do you explain the difference? Well, that one has a simple answer -- we play games out of choice and for fun, but the metrics are often thrust upon us.
That said, an even deeper question is addressed: if we hate metrics so much, why is our life so full of them? For that matter, you can't always blame "they're thrust upon us" as an excuse for metrics. People even follow them when they don't have to. Nguyen uses law school rankings as an example: before the rankings began, different law schools would prioritize different approaches. This one focuses more on having members of marganized communities enter, another focuses more on a particular type of law, still another on getting their students into particular law firms. It was an issue of values and students would need to do soul-searching on their own part about what sort of law school they wanted to enter. Then came rankings and everyone started just following the rankings. No soul-searching for students, and law schools themselves adjusted their missions, jettisoning their old values to score better in the areas the rankings base their metrics on. Nguyen calls this Value Capture: when you don't just have metrics, but internalize those metrics to determine your own values. And that's what really causes so much grief. Nguyen noted that in his own life, metrics that determine how his philosophy department should be run cost him so much anguish, that he at one point lost much of his interest in the field he's based his life studying.
OK, that went on too long about one example from the book, but it highlights the problems of metrics that determine sooooo many facets of our life. Nguyen identifies what he calls The Four Horsemen of Byreaucracy. These are the engines that really drive them, make them so important, and often oppressive.
The Horsemen: 1) Scale, which makes things comprehensible across wide areas, allowing for the power of portability, at the cost of paying attention to specific contexts the data came from. 2) (Mechanical) Rules, which gives us clear guidelines that everyone can follow, just like they follow the recipes in modern day cookbooks). They make it so everyone can follow along the same, but also mandate that everyone do it This Way. You trade accessibilty for adaptability. 3) (Replaceable) Parts: It makes it so that everything is a cog in the same machine - even the people being metric'd. You get interchangeability at the sacrifice of individual sensitivity and specificity. 4) Control, which Nguyen attests is the real key one. All metrics operate under the facade of objectivity, but in reality, they're always at the behest of whoever made them. They serve that person's purpose (whether the purpose is conscious or not) and with any bias baked into the concrete so deep you can't even see it. (That you can't see it makes it even better). Coordination is gained and autonomy lost. And this is how people just heard towards law school rankings and ignore any differing values law schools have (which, at this point, they don't really have any differing values due to complete Value Capture of the entire system).
So you lose adaptability, recognition of specific context, specificity, and autonomy while gaiing accessbility, portability, interchangibilty, and coordination. No wonder people often hate them.
He has no great plan of how to undo it. He argues on behalf on the spirit of play and an aesthetic appreciation of art, which doesn't just mean things you see in a museum but also anything you see around you can be appreciated like that. I'm not sure it comes up as a point in the book, but one thing I got out of the Pablo Torre interview is just how being aware of this process can help you navigate it and avoid the worst. Being aware of how you might have experienced Value Capture can help you break free of it, which seems to have helped Nguyen. (No, it's not systematic, but at least you can get a personal win out of it).
