The Green Revolution averted mass famine during the 20th century. The contraceptive pill gave women unprecedented freedom in planning their own lives. Both are widely recognised as scientific breakthroughs that transformed the world. But few know that those breakthroughs only happened when they did because of a philanthropist willing to take a risky bet on a new idea.
Holden Karnofsky has been studying philanthropy’s biggest success stories because he’s Executive Director of Open Philanthropy, a major foundation which gives away over $200 million a year — and he’s hungry for big wins.
In this conversation from 2018 Holden explains the philosophy of effective altruism and how he goes about searching for giving opportunities that can do the most good possible.

Of all the people whose well-being we should care about, only a small fraction are alive today. The rest are members of future generations who are yet to exist. Whether they’ll be born into a world that is flourishing or disintegrating – and indeed, whether they will ever be born at all – is in large part up to us. As such, the welfare of future generations should be our number one moral concern.
This conclusion holds true regardless of whether your moral framework is based on common sense, consequences, rules of ethical conduct, cooperating with others, virtuousness, keeping options open – or just a sense of wonder about the universe we find ourselves in.
That’s the view of Dr Toby Ord, a philosophy Fellow at the University of Oxford and co-founder of the effective altruism community.
In this conversation from 2017, Toby makes the case that aiming for a positive long-term future is likely the best way to improve the world.

The effective altruist research community tries to identify the highest impact things people can do to improve the world. Unsurprisingly, given the difficulty of such a massive and open-ended project, very different schools of thought have arisen about how to do the most good.
Today’s guest, Alexander Berger, leads Open Philanthropy’s ‘Global Health and Wellbeing’ programme, where he oversees around $175 million in grants each year, and ultimately aspires to disburse billions in the most impactful ways he and his team can identify.

Immanuel Kant is a profoundly influential figure in modern philosophy, and was one of the earliest proponents for universal democracy and international cooperation. He also thought that women have no place in civil society, that it was okay to kill illegitimate children, and that there was a ranking in the moral worth of different races.
Throughout history we’ve consistently believed, as common sense, truly horrifying things by today’s standards. According to University of Oxford Professor Will MacAskill, it’s extremely likely that we’re in the same boat today. If we accept that we’re probably making major moral errors, how should we proceed?
In this conversation from 2018, Will makes the case that we need to develop a moral view that criticises common sense intuitions, and gives us a chance to move beyond them.

Imagine that humanity has two possible futures ahead of it: Either we’re going to have a huge future like that, in which trillions of people ultimately exist, or we’re going to wipe ourselves out quite soon, thereby ensuring that only around 100 billion people ever get to live.
If there are eventually going to be 1,000 trillion humans, what should we think of the fact that we seemingly find ourselves so early in history? If the future will have many trillions of people, the odds of us appearing so strangely early are very low indeed.
If we accept the analogy, maybe we can be confident that humanity is at a high risk of extinction based on this so-called ‘doomsday argument‘ alone.
There are many critics of this theoretical ‘doomsday argument’, and it may be the case that it logically doesn’t work. This is why Ajeya Cotra — a senior research analyst at Open Philanthropy — spent time investigating it, with the goal of ultimately making better philanthropic grants.
In this conversation from 2021, Ajeya and Rob discuss both the doomsday argument and the challenge Open Phil faces striking a balance between taking big ideas seriously, and not going all in on philosophical arguments that may turn out to be barking up the wrong tree entirely.

Have you ever been infuriated by a doctor's unwillingness to give you an honest, probabilistic estimate about what to expect? Or a lawyer who won't tell you the chances you'll win your case?
Their behaviour is so frustrating because accurately predicting the future is central to every action we take. If we can't assess the likelihood of different outcomes we're in a complete bind, whether the decision concerns war and peace, work and study, or Black Mirror and RuPaul's Drag Race.
Which is why the research of Professor Philip Tetlock is relevant for all of us each and every day.
In this conversation from 2019, we discuss how his work can be applied to your personal life to answer high-stakes questions, like how likely you are to thrive in a given career path, or whether your business idea will be a billion-dollar unicorn — or fall apart catastrophically.

The barista gives you your coffee and change, and you walk away from the busy line. But you suddenly realise she gave you $1 less than she should have. Do you brush your way past the people now waiting, or just accept this as a dollar you’re never getting back?
According to philosophy Professor Hilary Greaves - Director of Oxford University's Global Priorities Institute, this simple decision will completely change the long-term future by altering the identities of almost all future generations.
This conversation from 2018 blends philosophy with an exploration of the mission and research agenda of the Global Priorities Institute: to develop the effective altruism movement within academia.

The 80,000 Hours Podcast is about “the world’s most pressing problems and how you can use your career to solve them”, and in this episode we tackle that question in the most direct way possible.
In 2019 we published a summary of all our key ideas, which links to many of our other articles, and which we are aiming to keep updated as our opinions shift.
All of us added something to it, but the single biggest contributor was our CEO and today's guest, Ben Todd, who founded 80,000 Hours along with Will MacAskill back in 2012.
In this conversation from 2020, Ben talks about some common misunderstandings of our advice, our key moral positions, and a high level overview of what 80,000 Hours generally recommends.

Is effective altruism just about donating money to fight poverty? Does it include a moral obligation to give? How do you talk about it to people who've never heard of it?
In this conversation from 2020, Arden Koehler and 80,000 Hours CEO Ben Todd cover a bunch of topics related to effective altruism.
We also have an article on misconceptions about effective altruism – based on Will MacAskill’s paper The Definition of Effective Altruism – and this episode can act as a companion piece.
