We all want to do something good for others, but making the world a better place is not easy. How do you know whether an idea works in practice and in the long run? And what works best? To know that, you need to investigate what your options are and what those options can bring about. That’s the core of effective altruism. Effective altruism is about the application of reason and evidence to use our resources as effectively as possible for the benefit of the planet and people around us.
