We face momentous decisions with important consequences throughout our lives. We are in an age of data deluge - by 2020 we'll be consuming 44 times more info than we are today, and we are faced with almost constant disruption. Did you know that each time you check an email it takes you 24 minutes to get back to your prior level of concentration? This is the environment in which we now make decisions. Who to trust? Who to believe? What to decide? Errors in decision-making lead young people to under-save for retirement, doctors to miss tumors, CEO's to make catastrophic investments, governments to engage in needless wars, and parents to irreversibly traumatize their children. Now that those experts we previously relied upon cannot be counted on to make decisions for us, we need to become empowered decision-makers, capable of making high-stakes decisions ourselves. It's time we started to think ourselves smarter. How to make better choices and smarter decisions when the stakes are high and the outcome really matters - whether you are a politician, a business-person, a professional or a parent - is what this book is about.
