Effective Altruism and Giving Strategically

A framework for thinking about how to do the most good per dollar donated, and the genuine debates around applying it.

Effective altruism is an approach to charitable giving that asks a specific, somewhat uncomfortable question: given a fixed amount of money or time, which causes and organizations will do the most measurable good with it? It treats cost-effectiveness - the amount of good achieved per dollar spent - as a central factor in giving decisions, rather than relying primarily on personal connection or emotional appeal.

Why cost-effectiveness varies enormously between causes

Research consistently shows that the same donated dollar can accomplish dramatically different amounts of measurable good depending on the specific cause and organization, particularly when comparing interventions in wealthier versus lower-income regions, where the same amount of money often stretches considerably further.

Comparing two donations directly

Effective altruism-aligned research organizations regularly publish comparisons showing that a fixed sum donated to a highly cost-effective global health intervention - such as distributing insecticide-treated bed nets to prevent malaria - can save a life for a small fraction of what many other well-intentioned charitable interventions cost per life saved, based on rigorous cost-effectiveness analysis.

Cause prioritization and its genuine critics

Cause prioritization - systematically ranking causes by estimated cost-effectiveness - is central to the effective altruism approach, but it has real critics too. Some argue it undervalues causes that are harder to measure quantitatively, like arts funding, local community needs, or advocacy work whose impact plays out over a longer, less measurable timeframe. Others argue it can undervalue genuine personal connection to a cause as a legitimate part of what makes giving meaningful.

Assuming cost-effectiveness data exists for every cause equally

Rigorous cost-effectiveness research is more developed for some causes - particularly global health and poverty interventions - than for others, like the arts, local community development, or long-term policy advocacy, where the outcomes are harder to measure precisely. The absence of a clean cost-effectiveness number doesn't necessarily mean a cause is less worthwhile - it can simply mean it's harder to measure.

Key takeaways
  • Effective altruism prioritizes cost-effectiveness - measurable good achieved per dollar donated.
  • The same donated dollar can achieve very different amounts of measurable impact depending on the cause.
  • Cause prioritization ranks causes systematically, but critics note it can undervalue harder-to-measure work.
  • A lack of clean cost-effectiveness data doesn't necessarily mean a cause matters less.
