In 2020, Oxford academic and 80,000 Hours trustee Dr Toby Ord released his book The Precipice: Existential Risk and the Future of Humanity. It's about how our long-term future could be better than almost anyone believes, but also how humanity's recklessness is putting that future at grave risk — in Toby's reckoning, a 1 in 6 chance of being extingu…

If I told you it’s possible to deliver an extra year of ideal primary-level education for 30 cents, would you believe me? Hopefully not – the claim is absurd on its face. But it may be true nonetheless. The very best education interventions are phenomenally cost-effective, but they’re not the kinds of things you’d expect, says Dr Rachel Glennerster…

COVID-19 has provided a vivid reminder of the damage biological threats can do. But the threat doesn’t come from natural sources alone. Weaponized contagious diseases — which were abandoned by the United States, but developed in large numbers by the Soviet Union, right up until its collapse — have the potential to spread globally and kill just as m…

Brian Christian is a bestselling author with a particular knack for accurately communicating difficult or technical ideas from both mathematics and computer science. The 80,000 Hours team found his new book The Alignment Problem to be an insightful and comprehensive review of the state of the research into making advanced artificial intelligence us…

Every year tens of billions of animals are raised in terrible conditions in factory farms before being killed for human consumption. Despite the enormous scale of suffering this causes, the issue is largely neglected, with only about $50 million dollars spent each year tackling the problem globally. Since 2015, Lewis Bollard has led Open Philanthro…

The killing of George Floyd has prompted a great deal of debate over whether the US should shrink its police departments. The research literature suggests that the presence of police officers does reduce crime, though they’re not cheap, and as is increasingly recognised, impose substantial harms on the populations they are meant to be protecting, e…

How many words in U.S. newspapers have been spilled on tax policy in the past five years? And how many words on CRISPR? Or meat alternatives? Or how AI may soon automate the majority of jobs? When people look back on this era, is the interesting thing going to have been fights over whether or not the top marginal tax rate was 39.5% or 35.4%, or is …

A golf-ball sized lump of uranium can deliver more than enough power to cover all your lifetime energy use. To get the same energy from coal, you’d need 3,200 tonnes of the stuff — a mass equivalent to 800 adult elephants, which would go on to produce more than 11,000 tonnes of CO2. That’s about 11,000 tonnes more than the uranium. Many people aren…

If a nuclear winter or asteroid impact blocked the sun for years, our inability to grow food would result in billions dying of starvation, right? According to Dr Dave Denkenberger, co-author of Feeding Everyone No Matter What: no. If he’s to be believed, nobody need starve at all. Even without the sun, Dave sees the Earth as a bountiful food source…

Most animals are hunted by predators, and constantly have to remain vigilant lest they be killed, and perhaps experience the terror of being eaten alive. Resource competition often leads to chronic hunger or starvation. Their diseases and injuries are never treated. In winter wild animals freeze to death and in droughts they die of heat or thirst. …

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 risk…

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 ge…

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 Healt…

Will SpaceX land people on Mars in the next decade? Will North Korea give up their nuclear weapons? Will your friend turn up to dinner? Spencer Greenberg, founder of ClearerThinking.org has a process for working out such real life problems. In this conversation from 2018, Spencer walks us through how to reason through difficult questions more accur…

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…

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 …

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 o…

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 Globa…

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 shi…

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 …
