Book summary “The life you can save”: summary

Introduction

You live in a world where extreme wealth and extreme poverty exist side by side. You might spend money on luxuries without a second thought while children elsewhere die from preventable causes. This stark reality creates a profound moral conflict that you must confront.

You have a strict moral obligation to donate surplus income to effective charities and save innocent lives from preventable poverty.

Peter Singer examines the ethical foundations of giving in The Life You Can Save. The book dismantles common objections to helping strangers and exposes the psychological barriers that stop you from acting. It offers a clear framework for effective altruism.

The book answers several vital questions:

• What do you owe to people living in extreme poverty?
• Why do you ignore distant suffering while helping those close to you?
• How can you ensure your donations do the most good?

1. The Argument to Help

You live in an affluent society where spending money on luxury items is common. Yet you also know that extreme poverty kills millions of children every year from preventable causes.

If you can prevent something very bad without sacrificing anything of comparable moral importance, you are morally obligated to do so.

Peter Singer lays out this core principle in Practical Ethics. Suffering and death from a lack of food, shelter, and medical care are bad things. If it is in your power to prevent such suffering without sacrificing anything nearly as important, failing to do so is wrong.

The Shallow Pond

Imagine walking past a shallow pond and seeing a toddler drowning. You could wade in and pull the child out, but doing so would ruin your new shoes and suit.

No one would sacrifice a child's life to save a pair of shoes. You would ruin your clothes without hesitation.

In 2011 in Foshan, China, a 2-year-old girl named Wang Yue was hit by a van and ignored by 18 people who walked or rode their bikes right past her while she bled in the street. This indifference leads to her death and brings instant revulsion. Yet millions of children die annually from preventable poverty while affluent people ignore their plight. Spending surplus income on unnecessary luxuries instead of saving lives through effective charities is logically identical to walking past the pond.

Bob and the Bugatti

Philosopher Peter Unger created a scenario about a man named Bob who is close to retirement. Bob has invested his life savings in a rare, uninsured Bugatti car.

He parks the car near a railway siding and walks down the tracks. Bob sees a runaway train hurtling toward a child playing on the tracks. He can throw a switch that will divert the train into his Bugatti, destroying his financial security to save the child's life.

Bob decides not to throw the switch, letting the child die to save his car. People condemn Bob's choice universally. Yet saving money for retirement or buying luxuries similarly prioritizes personal assets over distant human lives.

Traditional views on helping the poor align with this demanding moral standard. Major world religions and philosophical traditions explicitly mandate that sharing surplus wealth with the poor is a strict moral duty rather than optional charity.

The Bible contains 3,000 references to alleviating poverty. Thomas Aquinas argued that superabundance is owed by natural right to the poor for their sustenance.

Other traditions formalize giving as an obligation of justice:

• Jewish tzedakah treats charity as a requirement of righteousness and fairness;
• Islamic zakat requires giving 2.5% every year on liquid assets;
• Islamic sadaqa provides voluntary charity beyond the mandatory minimum.

Rick Warren visited South Africa and realized a tiny church operating from a tent and sheltering 25 children orphaned by AIDS was doing more for the poor than his entire megachurch. A man in Ghana described to a World Bank researcher how a small boy died of measles because his parents had no money for hospital treatment, dying a slow death out of poverty rather than the disease itself.

2. Common Objections to Giving

Common justifications for hoarding wealth and ignoring foreign suffering collapse under logical scrutiny and empirical evidence.

You might reject moral relativism as soon as someone commits an obviously heinous act, such as animal cruelty or terrorism. Rejecting moral relativism in extreme cases means you must reject it everywhere. Student Kathryn from Glennview High argued against judging those who refuse to give, while Douglas asserted that authors have no right to tell people what to do.

Investor Warren Buffett noted that his stock-picking talent would produce very little if he were dropped into the middle of Bangladesh or Peru. Economist Herbert Simon estimated that social capital is responsible for at least 90 percent of earnings in wealthy societies. Infrastructure, legal systems, and stable institutions enable success, whereas people in developing nations often work harder in worse conditions without escaping poverty.

Student Lucy argued that people work for their money and have the right to spend it on cars, houses, and suits. Having a legal or moral right to spend money on oneself does not mean doing so is ethically right. Choosing to spend money on luxuries instead of saving human lives can still be judged as morally wrong, akin to neglecting family obligations for trivial entertainment.

Ale Nodye, a Senegalese fisherman, was forced to attempt an illegal migration to the Canary Islands because industrial trawlers destroyed local fish stocks. Affluent nations contribute disproportionately to global problems that devastate developing economies, such as $300 million worth of fish taken by illegal industrial trawlers from Senegalese waters annually and a $1.3 billion total estimated illegal catch in West Africa. Industrialized nations have also caused climate change, with Africa contributing less than 3 percent of global greenhouse gas emissions since 1751.

Challenging Selfishness

A 2015 Kaiser Family Foundation poll showed Americans believed 26 percent of government spending went to foreign aid, whereas the real figure was under 1 percent. Citizens in wealthy nations like the United States and Australia drastically overestimate the percentage of their federal budgets allocated to foreign aid. When informed of the actual low percentages, public support for increasing aid to meet the United Nations target of 0.7 percent of gross national income rises significantly. In 2018, the United States gave 0.17 percent as official development assistance.

Fears that saving lives will cause catastrophic overpopulation are unfounded because rising living standards and education reliably reduce birth rates. In Mali, women with secondary education have an average of three children, compared to an average of seven for those with no education. Developing countries have 214 million women of reproductive age wanting to avoid pregnancy but not using modern contraception. Kerala, India, achieved an average of 1.7 children per woman due to higher literacy and gender equality.

Cash Transfers

Founders Michael Faye, Paul Niehaus, Jeremy Shapiro, and Rohit Wanchoo started GiveDirectly to transfer about $1,000 per family to people in extreme poverty. By the end of 2018, GiveDirectly reached 100,000 households. Controlled studies and randomized trials demonstrate that giving cash directly to poor families improves their living conditions without increasing alcohol consumption.

Unconditional cash transfers provide specific benefits:

• does not reduce the amount that adults work, but does reduce child labor;
• raises school attendance;
• increases economic autonomy;
• increases women's decision-making power;
• leads to greater diversity in diet;
• stimulates more use of health services.

Charlie Bresler transformed The Life You Can Save into an organization that encourages people to give to nonprofits vetted by independent research. Modern philanthropy relies on independent evaluators like GiveWell that rigorously assess the impact of charitable interventions. Researchers Laurence Chandy, Lorenz Noe, and Christine Zhang analyzed the global poverty gap and how billionaires could help close it in their January 2016 Brookings Institution blog post. An Oxfam report from January 2019 noted that the 26 richest people own as much as the poorest 50 percent.

3. Why Don't We Give More?

Evolutionary traits like parochialism and psychological traps like the identifiable victim effect prevent people from giving what ethics demand.

Psychological Barriers

Humans evolved as social mammals living in small tribal groups. Caring for kin and neighbors directly impacted survival in ancestral environments. This creates a deep-seated parochial bias where tragedies affecting foreigners evoke far less emotional disturbance and financial support. Adam Smith called this telescopic philanthropy because people care more about distant objects than immediate ones.

Following the 2004 Southeast Asian tsunami, which killed 220,000 people, Americans donated $1.54 billion. In contrast, the following year Americans gave $6.5 billion to help victims of Hurricane Katrina, which killed about 1,600 people inside the United States. Americans also donated $150 million following an earthquake in Pakistan that killed 73,000 people.

People are far more generous when responding to a single, identifiable individual in distress than to statistical data about large numbers of victims. Paul Slovic explains that humans use an affective system grounded in emotional responses and a deliberative system that works with numbers. The affective system triggers immediate action, whereas deliberation takes longer and lacks emotional impact.

Participants in an experiment gave significantly more donations to Save the Children when shown information about a 7-year-old Malawian girl named Rokia than when given general statistics about food shortages affecting over three million children in Malawi.

Psychological studies show that donors are more willing to help when a rescue mission saves a high proportion of people at risk. Futility thinking leads individuals to believe that making any smaller contribution is worthless when a problem is massive. Participants in a study were more willing to send aid to save 1,500 refugees out of a total camp population of 3,000 than they were to save 1,500 refugees out of a camp population of 10,000.

The presence of many other potential helpers drastically reduces an individual's personal sense of responsibility to take action. Popularized by psychologists John Darley and Bib Latané following the murder of Kitty Genovese, the bystander effect demonstrates that diffusion of responsibility strongly inhibits helpful behavior. In an experiment where students filled out questionnaires in a room, 70 percent of those who were alone offered help when a researcher in an adjacent room staged an accident. When a passive stooge was present in the room, only 7 percent offered help.

Overcoming Instincts

When individuals consider donating a substantial portion of their income, their willingness drops if they realize wealthier peers are not contributing fairly. In economic experiments known as the ultimatum game, proposers split a $10 sum with a responder who can reject the offer to leave both players with nothing. Many proposers choose an equal split, and responders routinely reject offers under 20 percent despite acting against their own financial self-interest.

While evolutionary psychology explains why humans respond intensely to local individuals, evolution has no moral direction. Treating evolved instincts as absolute ethical guides fails logical examination. Rational reflection dictates that the needs of distant strangers and large numbers of lives carry equal moral weight.

Rigorous ethical arguments and written appeals can successfully persuade people to overcome psychological barriers and commit to major philanthropic actions. Dean Spears and Diane Coffey were so inspired by Peter Singer's article on famine and morality that they moved to India and founded r.i.c.e. to study child health and poverty. A New York Times article on global poverty brought $600,000 through telephone lines at UNICEF and Oxfam America in the month after it appeared.

4. How to Build a Culture of Giving

Establishing social norms, formal pledges, workplace nudges, and corporate structures transforms philanthropy into a collective habit.

People are significantly more likely to donate to charity when they believe their peers or reference groups are already doing so. Psychologists Jen Shang and Rachel Croson tested funding drives for an American public radio station and found that telling callers that a recent donor gave a sum at the ninetieth percentile substantially increased donation amounts and renewal rates a year later. Similarly, telling Swedish students that 73 percent of school attendees contributed to a charity helping children in Uganda boosted donations from 43 percent to 79 percent.

Descriptive social information harnesses social influence and successfully increases contributions from new and renewing members. Yet a pervasive ideological belief in human self-interest suppresses open altruism, making people disguise generous acts behind selfish explanations. Sociologist Robert Wuthnow documented volunteers like Jack Casey who do 15 hours a week of volunteer work and rescue people but insist their motivations are purely self-serving to avoid being labeled do-gooders.

Pledges and Nudges

Formal pledges and giving communities provide mutual reinforcement, shared knowledge, and accountability that dramatically scale long-term philanthropic commitments. Toby Ord calculated his lifetime academic earnings at 1.5 million pounds, decided to live on one-third, and founded Giving What We Can, which later inspired thousands to pledge 10 percent of their income. Ten years after its founding, 4,000 members have donated nearly $150 million and pledged more than $1.5 billion in Giving What We Can. By 2019, 204 pledgers from 23 countries participated in The Giving Pledge, and 1,200 members from 30 countries pledged $708 million to charity through Founders Pledge.

Changing default options in workplaces and legal documents from opt-in to opt-out dramatically increases participation in charitable giving and organ donation. In Germany, where registration is opt-in, 11.5 deceased people per million are organ donors, compared with 25.4 deceased people per million in Austria where consent is presumed. Only 6.5 percent of wills include a charitable gift in the United States, United Kingdom, and Australia.

You can apply these insights through concrete workplace and legal adjustments:

• Propose an opt-out workplace giving program where a percentage of salary is automatically deducted for effective charities unless the employee opts out.
• Include an effective charity bequest clause in will templates and standard lawyer client recommendations.

Corporate and Family Culture

Australian companies like Bain & Company, CommBank, and The Good Guys implemented opt-out workplace giving programs and saw significantly higher participation rates. Goldman Sachs Gives has given $1.5 billion in grants since 2007. Furthermore, 65 percent of Fortune 500 companies have employee matching gift programs, and 8,500 companies in 100 countries have taken up Pledge 1 percent donating over $1 billion. Rob Keldoulis founded VivCourt Trading with a charitable trust as its sole shareholder, directing 50 percent of net revenue to charity and giving employees a social bonus to choose recipient organizations.

Modeling effective giving to children through structured pocket money systems and hands-on workshops creates lasting cultural change. Scott Pape recommends a Three Jam Jar system labeled splurge, smile, and give. Jon Behar developed Giving Games where 13,000 participants in 25 countries have taken part by voting on real money donations to effective charities.

You can cultivate philanthropic habits using similar structured mechanisms:

• Use the Three Jam Jar system labeled splurge, smile, and give for children's pocket money.
• Run Giving Games workshops where participants learn about pre-selected charities and vote on where to donate real money.
