In 2003, Saddam Hussein refused to let Iraqi weapons scientists leave the country to be interrogated. Given the overwhelming domestic support for an invasion at the time, most key figures in the U.S. took that as confirmation that he had something to hide — probably an active WMD program. But what about alternative explanations? Maybe those scientists knew about past crimes. Or maybe they’d defect. Or maybe giving in to that kind of demand would have humiliated Hussein in the eyes of enemies lik...

Today's episode is one of the most remarkable and really, unique, pieces of content we’ve ever produced (and I can say that because I had almost nothing to do with making it!). The producer of this show, Keiran Harris, interviewed our mutual colleague Howie about the major ways that mental illness has affected his life and career. While depression, anxiety, ADHD and other problems are extremely common, it's rare for people to offer detailed insight into their thoughts and struggles — and even ra...

For a chance to prevent enormous amounts of suffering, would you be brave enough to drive five hours to a remote location to meet a man who seems likely to be your enemy, knowing that it might be an ambush? Today’s guest — Leah Garcés — was. That man was a chicken farmer named Craig Watts, and that ambush never happened. Instead, Leah and Craig forged a friendship and a partnership focused on reducing suffering on factory farms. Leah, now president of Mercy For Animals (MFA), tried for years to ...

Imagine that you’re in the hospital for surgery. This kind of procedure is always safe, and always successful — but it can take anywhere from one to ten hours. You can’t be knocked out for the operation, but because it’s so painful — you’ll be given a drug that makes you forget the experience. You wake up, not remembering going to sleep. You ask the nurse if you’ve had the operation yet. They look at the foot of your bed, and see two different charts for two patients. They say “Well, you’re one ...

Donald Trump’s attempt to overturn the results of the 2020 election split the Republican party. There were those who went along with it — 147 members of Congress raised objections to the official certification of electoral votes — but there were others who refused. These included Brad Raffensperger and Brian Kemp in Georgia, and Vice President Mike Pence. Although one could say that the latter Republicans showed great courage, the key to the split may lie less in differences of moral character o...

Today we're launching a new podcast feed that might be useful to you and people you know. It's called ' Effective Altruism: An Introduction ', and it's a carefully chosen selection of ten episodes of this show, with various new intros and outros to guide folks through them. Basically, as the number of episodes of this show has grown, it has become less and less practical to ask new subscribers to go back and listen through most of our archives. So naturally new subscribers want to know... what s...

You might have heard fears like this in the last few years: What if Donald Trump was woken up in the middle of the night and shown a fake video — indistinguishable from a real one — in which Kim Jong Un announced an imminent nuclear strike on the U.S.? Today’s guest Nina Schick, author of Deepfakes: The Coming Infocalypse , thinks these concerns were the result of hysterical reporting, and that the barriers to entry in terms of making a very sophisticated ‘deepfake’ video today are a lot higher ...

How long do you think it’ll be before we’re able to bend the weather to our will? A massive rainmaking program in China, efforts to seed new oases in the Arabian peninsula, or chemically induce snow for skiers in Colorado. 100 years? 50 years? 20? Those who know how to write a teaser hook for a podcast episode will have correctly guessed that all these things are already happening today. And the techniques being used could be turned to managing climate change as well. Today’s guest, Kelly Wanser...

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 it going to be that human beings started to take control of human evolution; that we stood on the brink of eliminating immeasurable levels of sufferin...

COVID-19 has provided a vivid reminder of the power of biological threats. 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 many as an all-out nuclear war. For five years today’s guest — Andy Weber — was the US Assistant Secretary of Defense responsible for biological and other w...

Brian Christian is a bestselling author with a particular knack for accurately communicating difficult or technical ideas from both mathematics and computer science. Listeners loved our episode about his book Algorithms to Live By — so when the team read his new book, The Alignment Problem , and found it to be an insightful and comprehensive review of the state of the research into making advanced AI useful and reliably safe, getting him back on the show was a no-brainer. Brian has so much of su...

I suspect today's guest, Lewis Bollard, might be the single best person in the world to interview to get an overview of all the methods that might be effective for putting an end to factory farming and what broader lessons we can learn from the experiences of people working to end cruelty in animal agriculture. That's why I interviewed him back in 2017 , and it's why I've come back for an updated second dose four years later. That conversation became a touchstone resource for anyone wanting to u...

This is a crosspost of an episode of the Eureka Podcast . The interviewer is Misha Saul, a childhood friend of Rob's, who he has known for over 20 years. While it's not an episode of our own show, we decided to share it with subscribers because it's fun, and because it touches on personal topics that we don't usually cover on the show. Rob and Misha cover: • How Rob's parents shaped who he is (if indeed they did) • Their shared teenage obsession with philosophy, which eventually led to Rob worki...

You wake up in a mysterious box, and hear the booming voice of God: “I just flipped a coin. If it came up heads, I made ten boxes, labeled 1 through 10 — each of which has a human in it. If it came up tails, I made ten billion boxes, labeled 1 through 10 billion — also with one human in each box. To get into heaven, you have to answer this correctly: Which way did the coin land?” You think briefly, and decide you should bet your eternal soul on tails. The fact that you woke up at all seems like ...

Rebroadcast: this episode was originally released in March 2020. To do good, most of us look to use our time and money to affect the world around us today. But perhaps that's all wrong. If you took $1,000 you were going to donate and instead put it in the stock market — where it grew on average 5% a year — in 100 years you'd have $125,000 to give away instead. And in 200 years you'd have $17 million. This astonishing fact has driven today's guest, economics researcher Philip Trammell at Oxford's...

From one point of view academia forms one big 'epistemic' system — a process which directs attention, generates ideas, and judges which are good. Traditional print media is another such system, and we can think of society as a whole as a huge epistemic system, made up of these and many other subsystems. How these systems absorb, process, combine and organise information will have a big impact on what humanity as a whole ends up doing with itself — in fact, at a broad level it basically entirely ...

Over the last ten years, the idea that Facebook, Twitter, and YouTube are degrading political discourse and grabbing and monetizing our attention in an alarming way has gone mainstream to such an extent that it's hard to remember how recently it was a fringe view.

Had World War 1 never happened, you might never have existed. It’s very unlikely that the exact chain of events that led to your conception would have happened otherwise — so perhaps you wouldn't have been born. Would that mean that it's better for you that World War 1 happened (regardless of whether it was better for the world overall)? On the one hand, if you're living a pretty good life, you might think the answer is yes – you get to live rather than not. On the other hand, it sounds strange ...

A golf-ball sized lump of uranium can deliver more than enough power to cover all of your lifetime energy use. To get the same energy from coal, you’d need 3,200 tonnes of black rock — a mass equivalent to 800 adult elephants, which would produce more than 11,000 tonnes of CO2. That’s about 11,000 tonnes more than the uranium. Many people aren’t comfortable with the danger posed by nuclear power. But given the climatic stakes, it’s worth asking: Just how much more dangerous is it compared to fos...

When COVID-19 struck the US, everyone was told that hand sanitizer needed to be saved for healthcare professionals, so they should just wash their hands instead. But in India, many homes lack reliable piped water, so they had to do the opposite: distribute hand sanitizer as widely as possible. American advocates for banning single-use plastic straws might be outraged at the widespread adoption of single-use hand sanitizer sachets in India. But the US and India are very different places, and it m...

The killing of George Floyd has prompted a great deal of debate over whether the US should reduce the size of its police departments. The research literature suggests that the presence of police officers does reduce crime, though they're expensive and as is increasingly recognised, impose substantial harms on the populations they are meant to be protecting, especially communities of colour. So maybe we ought to shift our focus to effective but unconventional approaches to crime prevention, appro...
