The key insight in effective giving is not just comparing charities, but recognizing that most individuals can dramatically increase their positive impact by redirecting donations to highly effective opportunities they are likely unaware of, achieving up to 100 times more good with their money.

Common thought experiments attacking consequentialism (e.g., a doctor sacrificing one patient for five) are flawed because they ignore the full scope of consequences. A true consequentialist analysis would account for the disastrous societal impacts, such as the erosion of trust in medicine, which would make the act clearly wrong.

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.

Most donors choose a cause with their heart. Attempting to persuade them to switch to a more "cost-effective" cause is almost always futile and can feel judgmental. A more productive approach is to accept their passion and help them choose the most effective organization working on that specific issue.

The for-profit world is hyper-competitive with clear feedback loops like profit. The non-profit sector lacks these, making it less efficient. This inefficiency creates an opportunity; a focused, effective individual or charity can achieve disproportionately large impact because there is simply less competition.

Thought experiments like the 'River of Drowning Children' suggest strict altruism requires sacrificing your entire life. However, most plausible ethical theories reject this maximal demandingness. They acknowledge that your own well-being, family, and personal projects also hold moral weight and should not be entirely sacrificed.

To compare disparate causes like funding art vs. saving lives, use extreme hypotheticals. If someone agrees saving 100 children is better than a tiny chance of art for billionaires, they've conceded comparability. The debate then shifts to negotiating where the line is drawn, not whether one can be drawn.

Thought experiments like the trolley problem artificially constrain choices to derive a specific intuition. They posit perfect knowledge and ignore the most human response: attempting to find a third option, like breaking the trolley, that avoids the forced choice entirely.

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.
