Final Thoughts on Taking the First Step in Effective Giving

Three Buckets of Spending

A mental model for allocating personal finances into spending on oneself, spending on personal passions/community, and spending on evidence-based, high-impact charities. This approach aims to acknowledge multiple values without creating conflict.

Valuism

Spencer Greenberg's life philosophy suggesting individuals identify their intrinsic values and then act effectively to create what they value, recognizing that different values may map to different 'buckets' of action.

Moral Circle of Concern

The scope of beings or entities that an individual considers worthy of their ethical consideration and efforts to help. This can range from immediate family to all humans, animals, or even future generations, significantly influencing effective giving choices.

Multiplier Principle (Leverage)

A strategy in effective giving focused on maximizing impact by influencing larger systems or inspiring others. Examples include advocating for government policy changes or encouraging friends and family to give effectively, which can significantly amplify one's overall good.

10% Pledge

A personal, non-binding commitment to donate 10% of one's lifetime gross income to charities deemed to do the most good, according to one's own values. It's designed to be flexible over a lifetime and serves as a commitment device and a way to inspire others.

?
Can an average person significantly increase the good they do with their money?

Yes, many people can do over 100 times more good with their money than they currently do by learning about and acting on more impactful giving opportunities aligned with their values.

?
How does giving to a charity like Make-A-Wish compare to other charitable interventions?

While Make-A-Wish provides significant benefit to one child for about $10,000, the same amount could save the lives of two children from preventable diseases like malaria in low-income countries.

?
Why might large, well-known charities not always be the most effective for an additional dollar?

Large charities often excel at marketing, which can attract significant funding, but this doesn't always correlate with the most cost-effective impact for an additional dollar, as they may have diminishing returns or less urgent funding needs.

?
What are the five key principles for finding highly effective charities?

The five principles are: considering where money is most needed, using evidence from independent evaluations, focusing on cost-effectiveness, expanding one's moral circle of concern, and seeking multiplier effects (leverage).

?
What is the 10% Pledge?

The 10% Pledge is a personal commitment to donate 10% of one's gross lifetime income to charities that one believes can do the most good, offering flexibility in annual giving while maintaining a long-term commitment.

?
Why should someone take a charitable pledge instead of just deciding to give?

Pledging provides accountability, enhances the experience of giving by framing it as an allocation rather than a loss, and serves as a powerful tool to inspire others to also give effectively.

?
What is the income threshold to be in the top 10% of the world's income distribution?

To be in the top 10% of the world's income distribution, adjusted for purchasing power parity, one needs to earn about $23,000 post-tax in the US.

?
Can someone de-pledge from the 10% Pledge if their circumstances change?

Yes, the 10% Pledge is a serious but flexible commitment, and individuals can de-pledge if significant life events or changes in values make it no longer feasible or aligned with their principles.

1. Maximize Charitable Impact

Recognize that many people can do 100 times more good with their money by being aware of effective giving opportunities, such as saving two children’s lives from preventable diseases for $10,000 instead of significantly improving one child’s life.

2. Adopt “Three Buckets” Spending

Divide your spending into three categories: on yourself, on passions close to your heart, and on evidence-based, high-impact charities. Aim to move some money into the third bucket, as many people are unaware of these opportunities.

3. Apply Five Giving Principles

Use five principles—considering where money is most needed, using evidence, focusing on cost-effectiveness, expanding your moral circle, and seeking multiplier effects—to find and support the most effective charities. These principles can significantly multiply your impact.

4. Utilize Impact-Focused Evaluators

The easiest way to increase your giving impact is to follow recommendations from independent impact-focused evaluators like GiveWell or Animal Charity Evaluators. These organizations apply effective giving principles to identify high-impact opportunities.

5. Prioritize Where Money Needed

Consider where your money is most needed, such as shifting resources from supporting children in high-income countries to low-income countries where basic needs like healthcare are less met. This can significantly increase the good your donation does.

6. Give Based on Evidence

Support charities based on independent evaluations and evidence of their impact, rather than relying on marketing or personal intuitions. This approach helps ensure your donations are delivering actual value to those they aim to help.

7. Focus on Cost-Effectiveness

Evaluate charities not just by the good they do, but by how cost-effectively they achieve their goals, considering the total amount invested versus the total impact generated. This ensures your money goes further in creating positive outcomes.

8. Expand Your Moral Circle

Reflect on who is included in your moral circle of concern, such as animals or future generations, as expanding this circle can reveal new, highly leveraged opportunities for doing good. Many people are unaware of the large impact they could have on these groups.

9. Seek Multiplier Effects

Look for opportunities to leverage your impact, such as influencing government spending or inspiring others to give, which can multiply the good done far beyond your direct donation. Inspiring one person to give as much as you do can effectively double your impact.

10. Take a Giving Pledge

Consider taking a personal commitment, like the 10% pledge (10% of lifetime income to effective charities) or a trial pledge (smaller percentage/duration), to serve as an accountability mechanism, enhance your giving experience, and inspire others. The lifetime pledge offers flexibility, allowing for varying annual contributions.

11. Talk About Giving Positively

Inspire others by sharing your own giving experiences and asking what they think, rather than preaching or pitching. This approach fosters genuine conversations and can strengthen relationships, leading to a greater collective impact.

12. Beware Charity Marketing Bias

Recognize that charities often prioritize marketing to persuade donors, which may not align with maximizing actual impact. Large charities, in particular, may be effective at marketing but not necessarily at delivering the most good per dollar.

13. Avoid Holistic Charity Approaches

Be cautious of charities that implement multiple interventions or holistic approaches, as they may be less cost-effective than those specializing in one highly effective intervention. Specialization often leads to greater impact per dollar.

14. Separate Giving Decisions

Separate the decision of how much to give from where to give, as this can help you focus more attention on selecting effective charities. This approach can lead to more impactful giving choices.

15. Understand Global Income Position

Use tools like the “How Rich Am I Calculator” to understand your position in the global income distribution. Realizing you are in the top few percent globally can inform your capacity and motivation for effective giving.

16. Start Small with Giving

If interested in effective giving, take a small first step, such as a trial pledge of 1% of your income for six months. This low-commitment approach helps you experience the process and reflect on its value.

Many, if not most people, can probably do more than 100 times as much good as they do now if they knew about these other opportunities and by their own values lights.

Alex Imas

It's not about making the good the enemy of the perfect, or perfect the enemy of the good, I think is the saying. It's really about, we're probably spending, every year many of us are probably spending $5,000 somewhere, and they can think about whether they'd rather spend them on that versus saving a child's life.

Alex Imas

The market, the charitable market, if you will, is not very efficient because what's ultimately driving us to give is whether a charity is able to persuade us that we should give to them rather than whether they're actually delivering value to who they're trying to help.

Alex Imas

I think ultimately we're going back to incentives to a kind of a system that's wrong. But the nice thing is there is a solution to this, I think.

Alex Imas

I think the most easy win is in just starting to follow the recommendations of impact-focused evaluators.

Alex Imas

I think the idea of giving 10% to where it can be used a lot better is generally very appealing in my experience to people. Like, that's a good thing to exist. I have hardly ever heard someone say like, oh, no, you shouldn't do that. It's a really bad idea to give 10%.

Five Principles for Effective Giving

Alex Imas
  1. Consider where your money is most needed (e.g., low-income vs. high-income countries).
  2. Use evidence, ideally from independent evaluations of charities.
  3. Focus on cost-effectiveness, taking costs into account to maximize impact per dollar.
  4. Consider your moral circle of concern, including other beings or future generations if aligned with your values.
  5. Seek multiplier effects by influencing larger actors (like governments) or inspiring others to give.

Inspiring Others to Give Effectively

Alex Imas
  1. Share your own experience and reasons for giving, rather than preaching.
  2. Ask others what they think about effective giving and if they've considered it.
  3. Ask what might be blocking them from giving or giving more effectively.
  4. Be open to learning about their values and helping them live up to those values.
