Effective Altruism: An Introduction

As the world faces increasingly complex problems - from pandemics to global poverty and climate change – how do we decide where to focus our efforts and resources to do the most good possible? Effective altruism offers a way to do just that, focusing on evidence and rational arguments to identify crucial issues and the most impactful ways of solving them.

In this new book, philosopher Jacob Bauer cuts through the uncritical hype and wholesale dismissal around effective altruism to offer a balanced overview of this movement's core concepts and approaches to ‘doing good better’. With examples spanning malaria-preventing bed nets to the dangers of AI, he illuminates how effective altruism is addressing some of the world’s most pressing problems, all the while acknowledging its real limitations and showcasing its immense promise. 

Whether you are a skeptic or a new adherent seeking to understand the philosophy and community of effective altruism, this book is the definitive guide.
