Effective Altruism is a philosophy and social movement that aims to use evidence and reason to determine the most effective ways to improve the world. It encourages individuals to consider how their actions can have the greatest positive impact, often focusing on areas like global poverty, animal welfare, and existential risks. Proponents of Effective Altruism advocate for donating a significant portion of their income to highly effective charities, such as those evaluated by organizations like GiveWell. The movement also emphasizes the importance of career choices that can contribute to social good, encouraging people to pursue paths that maximize their positive influence.
