Don't judge a charity's effectiveness by its website. An Indian charity, Bandhan, had a 90s-era website but an evidence-based program praised by Nobel laureates. Organizations excellent at impact delivery may be poor at marketing, presenting an opportunity for diligent donors to find undervalued opportunities.

Prioritize projects that promise significant impact but face minimal resistance. High-friction projects, even if impactful, drain energy on battles rather than building. The sweet spot is in areas most people don't see yet, thus avoiding pre-emptive opposition.

To avoid guilt, divide spending into three buckets: 1) yourself, 2) causes you're passionate about, and 3) high-impact, evidence-based charities. This approach encourages adding effective giving without demanding the sacrifice of personal or local donations, making the practice more sustainable.

Reaching a 100x increase in charitable impact isn't from a single change but from combining principles that each act as a multiplier. For instance, shifting focus to a more neglected problem (10x) and choosing a leveraged policy solution (10x) can result in a 100x total improvement.

Your personal donations are just one part of your potential impact. By talking about your giving and inspiring just one other person to match your commitment, you can effectively double your philanthropic output. This interpersonal multiplier is a powerful and often overlooked form of leverage in doing good.

A critical flaw in philanthropy is the donor's need for control, which manifests as funding specific, personal projects instead of providing unrestricted capital to build lasting institutions. Lasting impact comes from empowering capable organizations, not from micromanaging project-based grants.

A study found that when people first pledge an amount and later decide on the specific charity, they give more money and allocate it more effectively. Decoupling these two decisions reduces cognitive load, allowing for more rational consideration of impact when choosing a recipient.

Frame philanthropic efforts not just by direct impact but as a "real-world MBA." Prioritize projects where, even if they fail, you acquire valuable skills and relationships. This heuristic, borrowed from for-profit investing, ensures a personal return on investment and sustained engagement regardless of the outcome.

A charity like Make-A-Wish can demonstrably create value, even exceeding its costs in healthcare savings. However, the same donation could save multiple lives elsewhere, illustrating the stark opportunity costs in charitable giving. Effective philanthropy requires comparing good options, not just identifying them.
