If two actions cost the same but one prevents more suffering, choosing between them can seem straightforward. Effective altruism begins with questions of this kind: how can people use their resources to help others more effectively?
The movement’s own introduction emphasizes evidence and careful reasoning in comparing opportunities to do good. That is a useful description of its stated project. It leaves important questions open about how comparisons are made and whose judgments determine the priorities. [1]
A measure contains choices
Imagine a fund comparing an intervention with immediate, measurable results against work whose benefits are slower and harder to count. A preference for the first may reflect stronger evidence. It may also reflect the ease of measuring the outcome. The distinction matters: a visible result and a valuable result are not always the same thing.
Uncertainty cannot simply be removed by assigning a number. An estimate depends on assumptions about what would otherwise happen, how long an effect lasts, and how confidently the evidence travels between settings. Good reasoning makes those assumptions available for criticism.
Accountability belongs inside the calculation
People affected by a decision may know things distant funders miss. Their participation can improve understanding of what is needed and reveal costs a model has overlooked. It also matters as a question of power: receiving assistance should not require surrendering every say in its form.
The strongest version of an evidence-minded ethic remains open to this challenge. It asks whether an action works while also asking who set the objective and who can contest it. A calculation can discipline generosity by exposing waste and inconsistency. It should also be disciplined by the people whose lives the calculation concerns. Doing more good requires attention to both consequences and the authority to define them.
