One movement, many journeys

Hear how members of the effective altruism community answer the question: how can we do the most good?

The principles of effective altruism

Scope sensitivity

We're committed to prioritizing actions that benefit more lives over actions that benefit fewer. The difference between saving a billion lives and saving ten isn't just a matter of degree — it's a fundamental difference in scale that should guide decisions about where to focus our efforts.

Impartiality

We aim to assist those who need it most without giving extra weight to people who are similar to us or geographically close. This approach often points us toward supporting people in developing countries, non-human animals, and future generations whose needs might otherwise be overlooked.

Scout mindset

We can help others more effectively when we work together to think clearly and orient toward truth, rather than defending our existing ideas. Since humans naturally struggle with biases and motivated reasoning, we try to cultivate intellectual humility by testing our beliefs and updating our views when presented with contrary evidence.

Recognition of tradeoffs

Because our time and money are limited, every choice to support one cause means not supporting another. We acknowledge these opportunity costs and try to make deliberate decisions about how to allocate our resources, recognizing that saying yes to one intervention often means saying no to others that might also do good.
