If you are reading this, you are in an extraordinary position. 

It has never been more possible for you to have a meaningful, positive impact on a massive scale. With the rise of evidence-driven interventions, we each have an unprecedented opportunity to save lives and prevent unnecessary suffering.

Effective Altruism is a growing social movement that combines both the heart and the head: compassion guided by data and reason. It's about dedicating a significant part of one's life to improving the world and rigorously asking the question, “Of all the possible ways to make a difference, how can I make the greatest difference?”

Apply evidence and reason to determine the most effective ways to improve the world.
