It makes sense that Barry Schwartz would follow up his previous book on the paradox of choice with this one, which is also about choice, about what is required for good decision making.
The premise of this book is that in many fields such as Medicine, Law, Banking and Education there has been a movement to institute more and more rules and incentives in order to improve performance and improve the bottom line. This has had the unintended consequences of constraining decision making and corrupting the people who work in these fields. He uses examples from psychology experiments (how people start to only focus on financial incentives and less on the moral dimension once money is introduced) and from real life to show how this can be counterproductive, such as the teacher who is constrained by the syllabus as to how each minute of the day is structured (including what words to say) and the judge who is not able to show leniency due to strict rules on sentencing.
He calls for a renewed focus on the "telos" or purpose of these professions and greater scope for decision-making and mentoring for the young professionals in each of these fields so they can have the empathy, compassion and discretion to act in the best way for each individual case. Then these professions can become more of a "calling" than just a "job".
The best business / pop psychology books, usually have one key idea which is slightly counter-intuitive, which then enters the popular consciousness - such as the 10,000 hours required to become world class from "Outliers" or that too much choice is actually detrimental from "The Paradox of Choice". These then change our view of the world and perhaps our own decision making. (I too can be a great guitarist if I am willing to put in the hours).
Unfortunately, at least for HMOs, the legal system and investment banking the issues are already well known and in the public consciousness (uncaring doctors, lawyers who advocate for criminals, greedy bankers). Professor Schwartz does a good job of highlighting the recent issues in education with all the standards testing and tying it with the rest of the industries. He also does a fine job with the psychological examples and industry analysis but sometimes the dispassionate tone makes it hard to identify with how corrupting these industries can be for the people involved. (Where he does try to describe case studies himself, it feels like high school creative writing, it comes across best when he quotes from the people themselves.) In terms of a solution he doesn't really lay one out, but cites individual cases or companies where people are trying to work against or outside the system, instead of how we can change the global mindset, making this a weak call to arms.
For the philosophers, be warned, in terms of the treatment of Aristotle, the treatment is cursory (maybe less than 20 pages in the whole book) where he states that we need to cultivate the virtues of courage, humanity and love, justice, temperance, transcendence and wisdom and knowledge, to frame and assess each situation on its own merits in order to have practical wisdom. It seems a little strange to restrict his analysis just to Aristotle, of the ancients he is not alone in advocating this, Confucius advocated seeking "ren" or humanity in each situation, as did many strains of Judaism. We also have alternative medicine practitioners trying to combat many of the ills that they see in the current healthcare system. Traditional martial arts systems also teach according to each student's strengths with mentoring of junior students by senior students in order to attain mastery. None of this is dealt with here.
The final chapter of the book about finding happiness and a calling seems rushed and has been done better elsewhere and I would recommend Richard Sennet's "The Corrosion of Character" and "The Craftsman" or "Shopclass as Soul Craft" by Matthew B. Crawford.
Again this is not to say that this is a bad book. If you are unfamiliar with the issues, then this is a good summary of the situation, the psychology experiment examples are very good and thought-provoking. But I just don't see this being one of those books which catch fire. It will be good as a paperback for a long flight.
