Black Box Thinking is an unique book about failure as well as how to make use of mistake to bounce back from adversity. Matthew Syed, who also wrote another bestseller Bounce, which I haven’t yet read, offered us totally different view of failure and success with his work. To be honest, before reading this book, I reckon that failure is uncomfortable situation that should be avoided. But, now I have a totally different insight into it. The book starts with a totally new perspective about failure. To make it clearer, the author tours readers through the process of two most responsible industries in the world and how they both react when it comes to failure. Both are considered as significant and responsible fields because they both deal with human life. Though both are assumed as responsible due to such aforementioned thing, totally different results are presented. In health care, failure and its misconceptions are everywhere following cover-ups. For individuals in healthcare, talent is favoured. In aviation, failure is now rare and seen as a learning opportunity. People in aviation think that talent is not enough and favours persistent. The author tries to re-formulate a conception of failure based on the two different perception of error in aviation and healthcare throughout book. It seems to me that the author successfully tells us that the combination of right mindset of failure and right system for turning failure into success is the secret of high performance. Before this book, I read another book titled Mindset: The New Psychology of Success written by Carol Dweck, a professor of psychology at Stanford University. The book also deals with the conception of failure and argues that growth mindset plays in important, perhaps the most important role, in individual’s development. Black Box Thinking also continues to stick with this argument and defend the importance of failure. Personally, I can’t tell that Matthew Syed and Carol Dweck are both right at this moment. But, circumstances and experiences I have had recently seems to confirms its validity. Having an example of profession is also down-to-earth to me, as a reader. It undoubtedly gives me a moment to reflect my own belief having to do with mistake as well as related to my profession. One particular thing I learned as well as experienced after reading this book is that testing our assumptions, seeing their flaws and learning from them. In chapter 3, the strangest thing about success is that it is built upon failure. When confronting the moment of failure, as the part 2 of this book tells, we tend to pose symptoms of denial, convictions, and blame. Instead, we should test first and have an expectation to learn from it. We sometimes carry the fallacy of perfectionism and fear failure when attempting something new. But, providing we have a bottom to up approach, it is possible to learn from the fall and come up with solutions to problems. Another interesting topic concerned success is the notion of marginal gains in chapter 9. Sir David Brailsford, who started the dominance of British cycling after he became a general manager of his country’s team, became an exemplar of how marginal gain can have big impact in high performance rather than sole big defining change. Small changes in every area of our life doesn’t make a difference at a time, however, add over the long term. Everything related to our certain goal could improve by only 1 percent, then those small gains would add up to remarkable achievement. With deep analysis of failure and success as well as some insightful and practical systems towards success, Matthew Syed managed to convey his secrets weapons towards success in life.
