Doing Good, Better: 5 Keys for More Effective Generosity

We often think that generosity is about intentions. What if it was also about results? This is the question William MacAskill poses in his book Doing Good, Better, dedicated to a movement still relatively unknown in France: effective altruism. Its principle is simple: if we want to help, let’s do it where our impact is greatest. This involves going beyond the obvious, questioning our intuitions, and sometimes exploring neglected or counter-intuitive causes with high transformative potential. This book challenges without guilt. It invites a step back, to measure the real effect of our donations, and to give not only with the heart but also discerningly. We offer a series of 5 thematic summaries to discover the book’s ideas, illustrated with concrete examples, and better understand how they can change our way of acting.
“We give with the heart. But the real impact doesn’t always follow.”

How many of us have spontaneously donated after a compelling report, an association’s stand, or simply an emotional impulse? Yet, behind these sincere gestures, the effectiveness of a donation often remains a gray area.

Take a documented example: PlayPump.

This water pumping system, powered by children playing on a carousel, seemed brilliant. It received significant media, philanthropic, and political support. But field evaluations revealed a different reality: as the novelty wore off, the pumps frequently broke down, and communities preferred their existing systems. Despite initial enthusiasm, the expected impact did not materialize. A clear demonstration: intuition alone does not ensure a project’s utility.

In ‘Doing Good, Better’, William MacAskill invites us to blend solidarity and rigorous analysis. Rather than cooling generosity, this approach aims to enhance its scope. What if we learned to direct our donations where they can truly change lives?

Why focus on donation effectiveness?

Certain actions allow, for the same amount, incomparable results.

The book provides a striking comparison: with 40,000 euros, you can train a guide dog for a blind person in a developed country. The same amount can also restore sight and autonomy to 500 people in Africa through trachoma surgery.

This isn’t a moral judgment on causes but an invitation to integrate a new criteria: observable effectiveness. It’s not about turning away from what we care about but expanding our perspective.

Our emotions often direct us toward the most visible and immediate situations. Yet, some massive challenges remain hidden due to media coverage. This is the case with intestinal parasites, affecting a billion people and severely harming children’s health and education, even though treatment costs just a few cents.

Finally, considering how we use donations isn’t a cold stance. It’s a responsibility: each euro given to one organization could have been a lever of major action elsewhere. Ignoring this means missing out on an impact that could have been possible.

Five Questions for Giving with Discernment

William MacAskill proposes a simple yet powerful framework to evaluate a charitable action. It’s not about imposing choices but fostering constructive reflection:

  • 1. How many people does this help, and to what extent?
  • 2. Is this the most relevant action I can support?
  • 3. Is the cause neglected in relation to its importance?
  • 4. Does my support truly make a difference, or would it happen without me?
  • 5. Are there tangible proofs that this works?

These guidelines may seem demanding, but they offer a valuable compass for those seeking to avoid the PlayPump effect: believing you are doing good without knowing if it’s truly useful.

How to Identify a High-Impact Organization?

GiveWell is one of the reference sources cited in the book. It evaluates associations based on transparency, evidence of effectiveness, costs, and unmet needs. It identifies interventions with measurable effects: mosquito nets against malaria, deworming programs, direct cash transfers.

The most promising causes are often the least visible: global health, animal suffering in industrial farming, or preventing future risks like pandemics and technological misuse. These are the cases where each additional euro given produces significant effects, a high marginal impact.

If this clashes with our natural preference for the local, it’s important to acknowledge it. The book simply reminds us that in a world where needs are unevenly distributed, every contribution can have different impacts depending on the context.

Concretely, how to start?

Why it's demanding (and why it’s worth it)

Refusing to rely on emotion, questioning certainties, accepting the uncertainty of long-term effects—all this requires effort. But it’s also what allows us to multiply our impact. The book illustrates with rigor, yet without excessive promise, how certain interventions have changed thousands of lives at very low costs.

Doing good isn’t enough. We must learn how to do good well. By providing clear guidelines and asking the right questions, everyone can enhance the real impact of their donation.

And now?

You don’t need to change everything. But starting today, you can test a new way of giving: by consulting an independent evaluation, discovering a lesser-known cause, or discussing these issues around you.

If you want to go further: Doing Good, Better by William MacAskill is a valuable read for anyone who wishes to act heartfully and discerningly. It offers a rigorous, accessible, and inspiring foundation to evolve your contribution approach.

What is the cost of a human life?

Human life is precious. It is natural to want to mobilise all our resources to save a life, even if it only prolongs a life by a week. But what happens when other people are also in danger, and our resources are not enough to help them all? As a society, we face practical limits that force us to make difficult decisions.
