#49 – Rachel Glennerster on a year’s worth of education for under a dollar and other ‘best buys’ in development

Podcast by and · Published December 20th, 2018

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 this week’s guest, Dr Rachel Glennerster.

She’s Chief Economist at the UK’s foreign aid agency DFID, and used to run J-PAL, the world-famous anti-poverty research centre based at MIT’s Economics Department, where she studied the impact of a wide range of approaches to improving education, health, and political institutions. According to Glennerster:

“…when we looked at the cost effectiveness of education programs, there were a ton of zeros, and there were a ton of zeros on the things that we spend most of our money on. So more teachers, more books, more inputs, like smaller class sizes – at least in the developing world – seem to have no impact, and that’s where most government money gets spent.”

“But measurements for the top ones – the most cost effective programs – say they deliver 460 LAYS per £100 spent ($US130). LAYS are Learning-Adjusted Years of Schooling. Each one is the equivalent of the best possible year of education you can have – Singapore-level.”

“…the two programs that come out as spectacularly effective… well, the first is just rearranging kids in a class.”

“You have to test the kids, so that you can put the kids who are performing at grade two level in the grade two class, and the kids who are performing at grade four level in the grade four class, even if they’re different ages – and they learn so much better. So that’s why it’s so phenomenally cost effective because, it really doesn’t cost anything.”

“The other one is providing information. So sending information over the phone [for example about how much more people earn if they do well in school and graduate]. So these really small nudges. Now none of those nudges will individually transform any kid’s life, but they are so cheap that you get these fantastic returns on investment – and we do very little of that kind of thing.”

(See the links section below to learn more about these kinds of results.)

In this episode, Dr Glennerster shares her decades of accumulated wisdom on which anti-poverty programs are overrated, which are neglected opportunities, and how we can know the difference, across a range of fields including health, empowering women and macroeconomic policy.

Regular listeners will be wondering – have we forgotten all about the lessons from episode 30 of the show with Dr Eva Vivalt? She threw several buckets of cold water on the hope that we could accurately measure the effectiveness of social programs at all.

According to Eva, her dataset of hundreds of randomised controlled trials indicates that social science findings don’t generalize well at all. The results of a trial at a school in Namibia tell us remarkably little about how a similar program will perform if delivered at another school in Namibia – let alone if it’s attempted in India instead.

Rachel offers a different and more optimistic interpretation of Eva’s findings.

Firstly, Rachel thinks it will often be possible to anticipate where studies will generalise and where they won’t. Studies are being lumped together that vary a great deal in i) how serious the problem is to start, ii) how well the program is delivered, iii) the details of the intervention itself. It’s no surprise that they have very variable results.

Rachel also points out that even if randomised trials can never accurately measure the effectiveness of every individual program, they can help us discover regularities of human behaviour that can inform everything we do. For instance, dozens of studies have shown that charging for preventative health measure like vaccinations will greatly reduce the number of people who take them up.

To learn more and figure out who you sympathise with, you’ll just have to listen to the the episode.

Regardless, Vivalt and Glennerster agree that we should continue to run these kinds of studies, and today’s episode delves into the latest ideas in global health and development. We discuss:

  • The development of aid work over the past 3 decades?
  • What’s the right balance of RCT work?
  • Do RCTs distract from broad economic growth and progress in these societies?
  • Overrated/underrated: charter cities, getting along with colleagues, cash transfers, cracking down on tax havens, micronutrient supplementation, pre-registration
  • The importance of using your judgement, experience, and priors
  • Things that reoccur in every culture
  • Do we produce too many programs where the quality of implementation matters?
  • Has the “empirical revolution” gone too far?
  • The increasing usage of Bayesian statistics
  • High impact gender equality interventions
  • Should we mostly focus on reforming macroeconomic policy in developing countries?
  • How important are markets for carbon?
  • What should we think about the impact the US and UK had in eastern Europe after the Cold War?

A simple checklist for overcoming life and career setbacks

Blog post by · Published December 19th, 2018

At 80,000 Hours we focus a lot on developing ambitious plans to dramatically improve the world.

Something we haven’t written so much about is how to overcome the challenges – heartbreak, rejection, failure, illness, grief, conflict and more – that are sure to arise as we attempt to follow through on those plans, and which risk throwing us off course.

We don’t have particular expertise on this topic, but I wanted to share an approach that me and some friends have found useful, and which might help you as well.

When bad things happen in life, the thoughts we then have about them have a big impact on how much they harm us. Even where we can’t avoid the direct suffering inflicted by a problem, we can at least avoid hurting ourselves further, by ruminating about it and getting trapped in a cycle of negative thoughts.

In the case of the minor annoyances we face every day, maintaining our equanimity can almost entirely eliminate the harm they cause us. And even when we face serious adversity, ensuring we think about it the right way can limit the damage, and save us from falling into depression or another negative spiral. (Though this list isn’t really suitable for seriously traumatic events.)

To help myself with this, I’ve made a checklist of questions I try to work through when something unpleasant happens, in order to reframe the situation and get over it as quickly as possible.

#48 – Brian Christian on computer science algorithms that tackle fundamental and universal problems — and whether they can help us live better in practice

Podcast by and · Published November 22nd, 2018

Ever felt that you were so busy you spent all your time paralysed trying to figure out where to start, and couldn’t get much done? Computer scientists have a term for this – thrashing – and it’s a common reason our computers freeze up. The solution, for people as well as laptops, is to ‘work dumber’: pick something at random and finish it, without wasting time thinking about the bigger picture.

Ever wonder why people reply more if you ask them for a meeting at 2pm on Tuesday, than if you offer to talk at whatever happens to be the most convenient time in the next month? The first requires a two-second check of the calendar; the latter implicitly asks them to solve a vexing optimisation problem.

What about estimating the probability of something you can’t model, and which has never happened before? Math has got your back: the likelihood is no higher than 1 in the number of times it hasn’t happened, plus one. So if 5 people have tried a new drug and survived, the chance of the next one dying is at most 1 in 6.

Bestselling author Brian Christian studied computer science, and in the book Algorithms to Live By he’s out to find the lessons it can offer for a better life. In addition to the above he looks into when to quit your job, when to marry, the best way to sell your house, how long to spend on a difficult decision, and how much randomness to inject into your life.

In each case computer science gives us a theoretically optimal solution. In this episode we think hard about whether its models match our reality.

One genre of problems Brian explores in his book are ‘optimal stopping problems’, the canonical example of which is ‘the secretary problem’. Imagine you’re hiring a secretary, you receive n applicants, they show up in a random order, and you interview them one after another. You either have to hire that person on the spot and dismiss everybody else, or send them away and lose the option to hire them in future.

It turns out most of life can be viewed this way – a series of unique opportunities you pass by that will never be available in exactly the same way again.

So how do you attempt to hire the very best candidate in the pool? There’s a risk that you stop before you see the best, and a risk that you set your standards too high and let the best candidate pass you by.

Mathematicians of the mid-twentieth century produced the elegant solution: spend exactly one over e, or approximately 37% of your search, just establishing a baseline without hiring anyone, no matter how promising they seem. Then immediately hire the next person who’s better than anyone you’ve seen so far.

It turns out that your odds of success in this scenario are also 37%. And the optimal strategy and the odds of success are identical regardless of the size of the pool. So as n goes to infinity you still want to follow this 37% rule, and you still have a 37% chance of success. Even if you interview a million people.

But if you have the option to go back, say by apologising to the first applicant and begging them to come work with you, and you have a 50% chance of your apology being accepted, then the optimal explore percentage rises all the way to 61%.

Today’s episode focuses on Brian’s book-length exploration of how insights from computer algorithms can and can’t be applied to our everyday lives. We cover:

  • Is it really important that people know these different models and try to apply them?
  • What’s it like being a human confederate in the Turing test competition? What can you do to seem incredibly human?
  • Is trying to detect fake social media accounts a losing battle?
  • The canonical explore/exploit problem in computer science: the multi-armed bandit
  • How can we characterize a computational model of what people are actually doing, and is there a rigorous way to analyse just how good their instincts actually are?
  • What’s the value of cardinal information above and beyond ordinal information?
  • What’s the optimal way to buy or sell a house?
  • Why is information economics so important?
  • The martyrdom of being a music critic
  • ‘Simulated annealing’, and the best practices in optimisation
  • What kind of decisions should people randomize more in life?
  • Is the world more static than it used to be?
  • How much time should we spend on prioritisation? When does the best solution require less precision?
  • How do you predict the duration of something when you you don’t even know the scale of how long it’s going to last?
  • How many heists should you go on if you have a certain fixed probability of getting arrested and having all of your assets seized?
  • Are pro and con lists valuable?
  • Computational kindness, and the best way to schedule meetings
  • How should we approach a world of immense political polarisation?
  • How would this conversation have changed if there wasn’t an audience?

Think twice before talking about ‘talent gaps’ — clarifying nine misconceptions

Blog post by · Published November 12th, 2018

After pushing the idea of ‘talent gaps’ in 2015, we’ve noticed increasing confusion about the term.

This is partly our fault. So, here’s a quick list of common misconceptions about talent gaps and how they can be fixed. This is all pretty rough and we’re still refining our own views, but we hope this might start to clarify this issue, while we work on better explaining the idea in our key content.

1. Problem areas are constrained by specific skills, not ‘talent’

Problem areas are rarely generically ‘talent constrained’. They’re instead constrained by specific skills and abilities. It’s nearly always clearer to talk about the specific needs of the field, ideally down to the level of specific profiles of people, rather than talent and funding in general.

For instance, work to positively shape the development of AI is highly constrained by the following:

  • ML researchers, especially those able to do field-defining work, who are interested in and understand AI safety, the alignment problem, and other issues relevant to the long-term development of AI.
  • People skilled in operations, especially those able to run nonprofits with under 50 people or academic institutes, and who are interested in and understand issues related to the long-term development of AI.
  • Strategy and policy researchers able to do disentanglement research in pre-paradigmatic fields.
  • People with the policy expertise and career capital to work in influential government positions who are also knowledgeable about and dedicated to the issue.

#47 – PhD or programming? Fast paths into aligning AI as a machine learning engineer, according to ML engineers Catherine Olsson & Daniel Ziegler

Podcast by and · Published November 2nd, 2018

After dropping out of his ML PhD at Stanford, Daniel Ziegler needed to decide what to do next. He’d always enjoyed building stuff and wanted to help shape the development of AI, so he thought a research engineering position at an org dedicated to aligning AI with human interests could be his best option.

He decided to apply to OpenAI, spent 6 weeks preparing for the interview, and actually landed the job. His PhD, by contrast, might have taken 6 years. Daniel thinks this highly accelerated career path may be possible for many others.

On today’s episode Daniel is joined by Catherine Olsson, who has also worked at OpenAI, and left her computational neuroscience PhD to become a research engineer at Google Brain. They share this piece of advice for those interested in this career path: just dive in. If you’re trying to get good at something, just start doing that thing, and figure out that way what’s necessary to be able to do it well.

To go with this episode, Catherine has even written a simple step-by-step guide to help others copy her and Daniel’s success.

Daniel thinks the key for him was nailing the job interview.

OpenAI needed him to be able to demonstrate the ability to do the kind of stuff he’d be working on day-to-day. So his approach was to take a list of 50 key deep reinforcement learning papers, read one or two a day, and pick a handful to actually reproduce. He spent a bunch of time coding in Python and TensorFlow, sometimes 12 hours a day, trying to debug and tune things until they were actually working.

Daniel emphasizes that the most important thing was to practice exactly those things that he knew he needed to be able to do. He also received an offer from the Machine Intelligence Research Institute, and so he had the opportunity to decide between two organisations focused on the global problem that most concerns him.

Daniel’s path might seem unusual, but both he and Catherine expect it can be replicated by others. If they’re right, it could greatly increase our ability to quickly get new people into ML roles in which they can make a difference.

Catherine says that her move from OpenAI to an ML research team at Google now allows her to bring a different set of skills to the table. Technical AI safety is a multifaceted area of research, and the many sub-questions in areas such as reward learning, robustness, and interpretability all need to be answered to maximize the probability that AI development goes well for humanity.

Today’s episode combines the expertise of two pioneers and is a key resource for anyone wanting to follow in their footsteps. We cover:

  • What is the field of AI safety? How could your projects contribute?
  • What are OpenAI and Google Brain doing?
  • Why would one decide to work on AI?
  • The pros and cons of ML PhDs
  • Do you learn more on the job, or while doing a PhD?
  • Why did Daniel think OpenAI had the best approach? What did that mean?
  • Controversial issues within ML
  • What are some of the problems that are ready for software engineers?
  • What’s required to be a good ML engineer? Is replicating papers a good way of determining suitability?
  • What fraction of software developers could make similar transitions?
  • How in-demand are research engineers?
  • The development of Dota 2 bots
  • What’s the organisational structure of ML groups? Are there similarities to an academic lab?
  • The fluidity of roles in ML
  • Do research scientists have more influence on the vision of an org?
  • What’s the value of working in orgs not specifically focused on safety?
  • Has learning more made you more or less worried about the future?
  • The value of AI policy work
  • Advice for people considering 23andMe

ML engineering for AI safety & robustness: a Google Brain engineer’s guide to entering the field

Article by and · Published November 2018

Technical AI safety is a multifaceted area of research, with many sub-questions in areas such as reward learning, robustness, and interpretability. These will all need to be answered in order to make sure AI development will go well for humanity as systems become more and more powerful.

Not all of these questions are best tackled with abstract mathematics research; some can be approached with concrete coding experiments and machine learning (ML) prototypes. As a result, some AI safety research teams are looking to hire a growing number of Software Engineers and ML Research Engineers.

Additionally, some research teams that may not think of themselves as focussed on ‘AI Safety’ per se, nonetheless work on related problems like verification of neural nets or learning from human feedback, and are often hiring engineers.

Note that this guide was written in November 2018 to complement an in-depth conversation on the 80,000 Hours Podcast with Catherine Olsson and Daniel Ziegler on how to transition from computer science and software engineering in general into ML engineering, with a focus on alignment and safety. If you like this guide, we’d strongly encourage you to check out the podcast episode where we discuss some of the instructions here, and other relevant advice.

What are the necessary qualifications for these positions?

Software Engineering: Some engineering roles on AI safety teams do not require ML experience. You might already be prepared to apply to these positions if you have the following qualifications:

  • BSc/BEng degree in computer science or another technical field (or comparable experience)
  • Strong knowledge of software engineering (as a benchmark: could pass a Google software engineering interview)
  • Interest in working on AI safety
  • (usually) Willingness to move to London or the San Francisco Bay Area

If you’re a software engineer with an interest in these roles,

New article: Have a particular strength? Already an expert in a field? Here are the socially impactful careers 80,000 Hours suggests you consider first.

Blog post by · Published October 24th, 2018

We’ve published a new article that summarises our advice based on your strengths and link you to the most relevant articles for you to read:

This list is preliminary. We wanted to publish our existing thoughts on what to do with each skill, but can easily see ourselves changing our minds over the coming years.

You can read about our general process and what career paths we recommend in our full article.

Sometimes, however, it’s possible to give more specific advice about what options to consider to people who already have pre-existing experience or qualifications, or are unusually good at a certain type of work.

In this article, we provide a list of skills, and for each one give a list of socially-impactful options that people who are unusually good in that area should most often consider.

We start with three “strengths” (quantitative, verbal & social, and visual). Then we go on to give advice for people with existing experience in fifteen specific fields.

Bear in mind it’s often possible to completely change field: we’ve seen people switch from philosophy to software engineering, and architecture into economics. Nonetheless, these are good starting points.

The skill types also overlap, and you probably also have several of them. The aim is just to give you some tips on narrowing down your options more quickly.

#46 – Philosopher Hilary Greaves on moral cluelessness, population ethics, probability within a multiverse, & harnessing the brainpower of academia to tackle the most important research questions

Podcast by and · Published October 23rd, 2018

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, which is hiring now – this simple decision will completely change the long-term future by altering the identities of almost all future generations.

How? Because by rushing back to the counter, you slightly change the timing of everything else people in line do during that day — including changing the timing of the interactions they have with everyone else. Eventually these causal links will reach someone who was going to conceive a child.

By causing a child to be conceived a few fractions of a second earlier or later, you change the sperm that fertilizes their egg, resulting in a totally different person. So asking for that $1 has now made the difference between all the things that this actual child will do in their life, and all the things that the merely possible child – who didn’t exist because of what you did – would have done if you decided not to worry about it.

As that child’s actions ripple out to everyone else who conceives down the generations, ultimately the entire human population will become different, all for the sake of your dollar. Will your choice cause a future Hitler to be born, or not to be born? Probably both!

Some find this concerning. The actual long term effects of your decisions are so unpredictable, it looks like you’re totally clueless about what’s going to lead to the best outcomes. It might lead to decision paralysis — you won’t be able to take any action at all.

Prof Greaves doesn’t share this concern for most real life decisions. If there’s no reasonable way to assign probabilities to far-future outcomes, then the possibility that you might make things better in completely unpredictable ways is more or less canceled out by the equally plausible possibility that you might make things worse in equally unpredictable ways.

But, if instead we’re talking about a decision that involves highly-structured, systematic reasons for thinking there might be a general tendency of your action to make things better or worse — for example if we increase economic growth — Prof Greaves says that we don’t get to just ignore the unforeseeable effects.

When there are complex arguments on both sides, it’s unclear what probabilities you should assign to this or that claim. Yet, given its importance, whether you should take the action in question actually does depend on figuring out these numbers.

So, what do we do?

Today’s episode blends philosophy with an exploration of the mission and research agenda of the Global Priorities Institute: to develop the effective altruism movement within academia. We cover:

  • What’s the long term vision of the Global Priorities Institute?
  • How controversial is the multiverse interpretation of quantum physics?
  • What’s the best argument against academics just doing whatever they’re interested in?
  • How strong is the case for long-termism? What are the best opposing arguments?
  • Are economists getting convinced by philosophers on discount rates?
  • Given moral uncertainty, how should population ethics affect our real life decisions?
  • How should we think about archetypal decision theory problems?
  • The value of exploratory vs. basic research
  • Person affecting views of population ethics, fragile identities of future generations, and the non-identity problem
  • Is Derek Parfit’s repugnant conclusion really repugnant? What’s the best vision of a life barely worth living?
  • What are the consequences of cluelessness for those who based their donation advice on GiveWell style recommendations?
  • How could reducing global catastrophic risk be a good cause for risk-averse people?
  • What’s the core difficulty in forming proper credences?
  • The value of subjecting EA ideas to academic scrutiny
  • The influence of academia in society
  • The merits of interdisciplinary work
  • The case for why operations is so important in academia
  • The trade off between working on important problems and advancing your career

New article: Ways people trying to do good accidentally make things worse, and how to avoid them

Blog post by · Published October 22nd, 2018

We’ve published a new article about how to avoid accidentally causing harm through your career:

“We encourage people to work on problems that are neglected by others and large in scale. Unfortunately those are precisely the problems where people can do the most damage if their approach isn’t carefully thought through.

If a problem is very important, then setting back the cause is very bad. If a problem is so neglected that you’re among the first focused on it, then you’ll have a disproportionate influence on the field’s reputation, how likely others are to enter it, and many early decisions that could have path-dependent effects on the field’s long-term success.

We don’t particularly enjoy writing about this admittedly demotivating topic. Ironically, we expect that cautious people – the folks who least need this advice – will be the ones most likely to take it to heart.

Nonetheless we think cataloguing these risks is important if we’re going to be serious about having an impact in important but ‘fragile’ fields like reducing extinction risk.

In this article, we’ll list six ways people can unintentionally set back their cause. You may already be aware of most of these risks, but we often see people neglect one or two of them when new to a high stakes area – including us when we were starting 80,000 Hours.”

#45 – Economist Tyler Cowen says our overwhelming priorities should be maximising economic growth and making civilisation more stable. Is he right?

Podcast by and · Published October 17th, 2018

I’ve probably spent more time reading Tyler Cowen – Professor of Economics at George Mason University – than any other author. Indeed it’s his incredibly popular blog Marginal Revolution that prompted me to study economics in the first place. Having spent thousands of hours absorbing Tyler’s work, it was a pleasure to be able to question him about his latest book and personal manifesto: Stubborn Attachments: A Vision for a Society of Free, Prosperous, and Responsible Individuals.

Tyler makes the case that, despite what you may have heard, we can make rational judgments about what is best for society as a whole. He argues:

  1. Our top moral priority should be preserving and improving humanity’s long-term future
  2. The way to do that is to maximise the rate of sustainable economic growth
  3. We should respect human rights and follow general principles while doing so.

We discuss why Tyler believes all these things, and I push back where I disagree. In particular: is higher economic growth actually an effective way to safeguard humanity’s future, or should our focus really be elsewhere?

In the process we touch on many of moral philosophy’s most pressing questions: Should we discount the future? How should we aggregate welfare across people? Should we follow rules or evaluate every situation individually? How should we deal with the massive uncertainty about the effects of our actions? And should we trust common sense morality or follow structured theories?

After covering the book, the conversation ranges far and wide. Will we leave the galaxy, and is it a tragedy if we don’t? Is a multi-polar world less stable? Will humanity ever help wild animals? Why do we both agree that Kant and Rawls are overrated?

Today’s interview is released on both the 80,000 Hours Podcast and Tyler’s own show: Conversation with Tyler.

Tyler may have had more influence on me than any other writer but this conversation is richer for our remaining disagreements. If the above isn’t enough to tempt you to listen, we also look at:

  • Why couldn’t future technology make human life a hundred or a thousand times better than it is for people today?
  • Why focus on increasing the rate of economic growth rather than making sure that it doesn’t go to zero?
  • Why shouldn’t we dedicate substantial time to the successful introduction of genetic engineering?
  • Why should we completely abstain from alcohol and make it a social norm?
  • Why is Tyler so pessimistic about space? Is it likely that humans will go extinct before we manage to escape the galaxy?
  • Is improving coordination and international cooperation a major priority?
  • Why does Tyler think institutions are keeping up with technology?
  • Given that our actions seem to have very large and morally significant effects in the long run, are our moral obligations very onerous?
  • Can art be intrinsically valuable?
  • What does Tyler think Derek Parfit was most wrong about, and what was he was most right about that’s unappreciated today?
  • How should we think about animal suffering?
  • Do self-aware entities have to be biological in some sense?
  • What’s the most likely way that the worldview presented in Stubborn Attachments could be fundamentally wrong?
  • During ‘underrated vs overrated’, should guests say ‘appropriately rated’ more often?

What skills or experience are most needed within professional effective altruism in 2018? And which problems are most effective to work on? New survey of organisational leaders.

Blog post by and · Published October 8th, 2018

Read this to see the 2019 data.

Update April 2019: We think that our use of the term ‘talent gaps’ in this post (and elsewhere) has caused some confusion. We’ve written a post clarifying what we meant by the term and addressing some misconceptions that our use of it may have caused. Most importantly, we now think it’s much more useful to talk about specific skills and abilities that are important constraints on particular problems rather than talking about ‘talent constraints’ in general terms. This page may be misleading if it’s not read in conjunction with our clarifications.

What are the most pressing needs in the effective altruism community right now? What problems are most effective to work on? Who should earn to give and who should do direct work? We surveyed managers at organisations in the community to find out their views. These results help to inform our recommendations about the highest impact career paths available.

Our key finding is that for the questions that we asked 12 months ago, the results have not changed very much. This gives us more confidence in our survey results from 2017.

We also asked some new questions, including about the monetary value placed on our priority paths, discount rates on talent and how current leaders first discovered and got involved in effective altruism.

Research isn’t the only way academics can have a large impact

When we think of academic careers, research is what first comes to mind, but academics have many other pathways to impact which are less often considered. Academics can also influence public opinion, advise policy-makers, or manage teams of other researchers to help them be more productive.

If any of these routes might turn out to be a good fit for you, then it makes the path even more attractive. We’ll sketch out some of these other paths:

1. Public outreach

Peter Singer’s career began in an ordinary enough way for a promising young academic, studying philosophy at Oxford University. But he soon started moving in a different direction from his peers,

#44 – Paul Christiano on how OpenAI is developing real solutions to the ‘AI alignment problem’, and his vision of how humanity will progressively hand over decision-making to AI systems

Podcast by and · Published October 2nd, 2018

Paul Christiano is one of the smartest people I know and this episode has one of the best explanations for why AI alignment matters and how we might solve it. After our first session produced such great material, we decided to do a second recording, resulting in our longest interview so far. While challenging at times I can strongly recommend listening – Paul works on AI himself and has a very unusually thought through view of how it will change the world. Even though I’m familiar with Paul’s writing I felt I was learning a great deal and am now in a better position to make a difference to the world.

A few of the topics we cover are:

  • Why Paul expects AI to transform the world gradually rather than explosively and what that would look like
  • Several concrete methods OpenAI is trying to develop to ensure AI systems do what we want even if they become more competent than us
  • Why AI systems will probably be granted legal and property rights
  • How an advanced AI that doesn’t share human goals could still have moral value
  • Why machine learning might take over science research from humans before it can do most other tasks
  • Which decade we should expect human labour to become obsolete, and how this should affect your savings plan.

—

Here’s a situation we all regularly confront: you want to answer a difficult question, but aren’t quite smart or informed enough to figure it out for yourself. The good news is you have access to experts who are smart enough to figure it out. The bad news is that they disagree.

If given plenty of time – and enough arguments, counterarguments and counter-counter-arguments between all the experts – should you eventually be able to figure out which is correct? What if one expert were deliberately trying to mislead you? And should the expert with the correct view just tell the whole truth, or will competition force them to throw in persuasive lies in order to have a chance of winning you over?

In other words: does ‘debate’, in principle, lead to truth?

According to Paul Christiano – researcher at the machine learning research lab OpenAI and legendary thinker in the effective altruism and rationality communities – this question is of more than mere philosophical interest. That’s because ‘debate’ is a promising method of keeping artificial intelligence aligned with human goals, even if it becomes much more intelligent and sophisticated than we are.

It’s a method OpenAI is actively trying to develop, because in the long-term it wants to train AI systems to make decisions that are too complex for any human to grasp, but without the risks that arise from a complete loss of human oversight.

If AI-1 is free to choose any line of argument in order to attack the ideas of AI-2, and AI-2 always seems to successfully defend them, it suggests that every possible line of argument would have been unsuccessful.

But does that mean that the ideas of AI-2 were actually right? It would be nice if the optimal strategy in debate were to be completely honest, provide good arguments, and respond to counterarguments in a valid way. But we don’t know that’s the case.

According to Paul, it’s clear that if the judge is weak enough, there’s no reason that an honest debater would be at an advantage. But the hope is that there is some threshold of competence above which debates tend to converge on more accurate claims the longer they continue.

Most real world debates are set up under highly suboptimal conditions; judges usually don’t have a lot of time to think about how to best get to the truth, and often have bad incentives themselves. But for AI safety via debate, researchers are free to set things up in the way that gives them the best shot. And if we could understand how to construct systems that converge to truth, we would have a plausible way of training powerful AI systems to stay aligned with our goals.

This is our longest interview so far for good reason — we cover a fascinating range of topics:

  • What could people do to shield themselves financially from potentially losing their jobs to AI?
  • How important is it that the best AI safety team ends up in the company with the best ML team?
  • What might the world look like if several states or actors developed AI at the same time (aligned or otherwise)?
  • Would artificial general intelligence grow in capability quickly or slowly?
  • How likely is it that transformative AI is an issue worth worrying about?
  • What are the best arguments against being concerned?
  • What would cause people to take AI alignment more seriously?
  • Concrete ideas for making machine learning safer, such as iterated amplification.
  • What does it mean to say that a crow-like intelligence could be much better at science than humans?
  • What is ‘prosaic AI’?
  • How do Paul’s views differ from those of the Machine Intelligence Research Institute?
  • The importance of honesty for people and organisations
  • What are the most important ways that people in the effective altruism community are approaching AI issues incorrectly?
  • When would an ‘unaligned’ AI nonetheless be morally valuable?
  • What’s wrong with current sci-fi?

Recent research we’ve published: Our top 10 careers for social impact; Congressional staffing; Comparative advantage; And can you guess which psychology experiments will replicate?

Blog post by · Published September 30th, 2018

We recently published a number of new articles that you might have missed if you don’t follow us on social media (Facebook and Twitter) or our research newsletter.

Probably our most important release for this year is this article summarising many of our key findings since we started in 2011:

It outlines our new suggested process anyone can use to generate a short-list of high-impact career options given their personal situation.

It then describes the top five key categories of career we most often recommend, which should produce at least one good option for almost all graduates, and why we’re enthusiastic about them.

It goes on to list and explains the top 10 “priority paths” we want to draw attention to, because we think they can enable to right person to do a particularly large amount of good for the world.

#43 – Daniel Ellsberg on the creation of nuclear doomsday machines, the institutional insanity that maintains them, and a practical plan for dismantling them

Podcast by and · Published September 24th, 2018

In Stanley Kubrick’s iconic film Dr. Strangelove, the American president is informed that the Soviet Union has created a secret deterrence system which will automatically wipe out humanity upon detection of a single nuclear explosion in Russia. With US bombs heading towards the USSR and unable to be recalled, Dr Strangelove points out that “the whole point of this Doomsday Machine is lost if you keep it a secret – why didn’t you tell the world, eh?” The Soviet ambassador replies that it was to be announced at the Party Congress the following Monday: “The Premier loves surprises”.

Daniel Ellsberg – leaker of the Pentagon Papers which helped end the Vietnam War and Nixon presidency – claims in his new book The Doomsday Machine: Confessions of a Nuclear War Planner that Dr. Strangelove might as well be a documentary. After attending the film in Washington DC in 1964, he and a military colleague wondered how so many details of the nuclear systems they were constructing had managed to leak to the filmmakers.

The USSR did in fact develop a doomsday machine, Dead Hand, which probably remains active today.

If the system can’t contact military leaders, it checks for signs of a nuclear strike. Should its computers determine that an attack occurred, it would automatically launch all remaining Soviet weapons at targets across the northern hemisphere.

As in the film, the Soviet Union long kept Dead Hand completely secret, eliminating any strategic benefit, and rendering it a pointless menace to humanity.

You might think the United States would have a more sensible nuclear launch policy. You’d be wrong.

As Ellsberg explains based on first-hand experience as a nuclear war planner in the early stages of the Cold War, the notion that only the president is able to authorize the use of US nuclear weapons is a carefully cultivated myth.

The authority to launch nuclear weapons is delegated alarmingly far down the chain of command – significantly raising the chance that a lone wolf or communication breakdown could trigger a nuclear catastrophe.

The whole justification for this is to defend against a ‘decapitating attack’, where a first strike on Washington disables the ability of the US hierarchy to retaliate. In a moment of crisis, the Russians might view this as their best hope of survival.

Ostensibly, this delegation removes Russia’s temptation to attempt a decapitating attack – the US can retaliate even if its leadership is destroyed. This strategy only works, though, if you tell the enemy you’ve done it.

Instead, since the 50s this delegation has been one of the United States most closely guarded secrets, eliminating its strategic benefit, and rendering it another pointless menace to humanity.

Even setting aside the above, the size of the Russian and American nuclear arsenals today makes them doomsday machines of necessity. According to Ellsberg, if these arsenals are ever launched, whether accidentally or deliberately, they would wipe out almost all human life, and all large animals.

Strategically, the setup is stupid. Ethically, it is monstrous.

If the US or Russia sent its nuclear arsenal to destroy the other, would it even make sense to retaliate? Ellsberg argues that it doesn’t matter one way or another. The nuclear winter generated by the original attack would be enough to starve to death most people in the aggressor country within a year anyway. Retaliation would just slightly speed up their demise.

So – how was such a system built? Why does it remain to this day? And how might we shrink our nuclear arsenals to the point they don’t risk the destruction of civilization?

Daniel explores these questions eloquently and urgently in his book (that everyone should read), and this conversation is a gripping introduction. We cover:

  • Why full disarmament today would be a mistake
  • What are our greatest current risks from nuclear weapons?
  • What has changed most since Daniel was working in and around the government in the 50s and 60s?
  • How well are secrets kept in the government?
  • How much deception is involved within the military?
  • The capacity of groups to commit evil
  • How Hitler was more cautious than America about nuclear weapons
  • What was the risk of the first atomic bomb test?
  • The effect of Trump on nuclear security
  • What practical changes should we make? What would Daniel do if he were elected president?
  • Do we have a reliable estimate of the magnitude of a ‘nuclear winter’?
  • What would be the optimal number of nuclear weapons for the US and its allies to hold?
  • What should we make of China’s nuclear stance? What are the chances of war with China?
  • Would it ever be right to respond to a nuclear first strike?
  • Should we help Russia get better attack detection methods to make them less anxious?
  • How much power do lobbyists really have?
  • Has game theory had any influence over nuclear strategy?
  • Why Gorbachev allowed Russia’s covert biological warfare program to continue
  • Is it easier to help solve the problem from within the government or at outside orgs?
  • What gives Daniel hope for the future?

American with a science PhD? Get a fast-track into AI and STEM policy by applying for the acclaimed AAAS Science & Technology Fellowship by Nov 1.

Blog post by · Published September 18th, 2018

Within just four years of finishing her PhD in biophysics, Jessica Tuchman Mathews was Director of Global Issues for President Carter’s National Security Council. In her first year in the role she helped put together a nuclear non-proliferation pact among 15 countries including the US and the Soviet Union.

Later in her career, Jessica served as Deputy to the Undersecretary of State for Global Affairs, wrote a weekly column for the Washington Post, and most recently served as President of the Carnegie Endowment for International Peace, an influential Washington-based foreign policy think tank.

What launched such an successful career? In our conversation with Jessica, she argued it was the AAAS Science & Technology (S&T) Policy Fellowship. Jessica was selected as one of their inaugural fellows in 1973.

In this article we argue that for eligible people interested in our top recommended problem areas and S&T policy careers the AAAS S&T Policy Fellowship is a valuable springboard that could rapidly advance your career as it did for Jessica.

The opportunity

At 80,000 Hours, we think the AAAS Policy Fellowship is one of the best routes into the US Government for people with a STEM or social science PhD, or an engineering masters and three years of industry experience.

Policy fellows work within the US Government for one year in policy-related roles relevant to science and technology. Nearly 300 fellows are accepted each year, and almost all of them take assignments within the executive branch,

#42 – Amanda Askell on tackling the ethics of infinity, being clueless about the effects of our actions, and having moral empathy for intellectual adversaries

Podcast by and · Published September 11th, 2018

Consider two familiar moments at a family reunion.

Our host, Uncle Bill, is taking pride in his barbequing skills. But his niece Becky says that she now refuses to eat meat. A groan goes round the table; the family mostly think of this as an annoying picky preference. But were it viewed as a moral position rather than personal preference – as they might if instead Becky were avoiding meat on religious grounds – it would usually receive a very different reaction.

An hour later Bill expresses a strong objection to abortion. Again, a groan goes round the table: the family mostly think that he has no business in trying to foist his regressive preferences on other people’s personal lives. But if considered not as a matter of personal taste, but rather as a moral position – that Bill genuinely believes he’s opposing mass-murder – his comment might start a serious conversation.

Amanda Askell, who recently completed a PhD in philosophy at NYU focused on the ethics of infinity, thinks that we often betray a complete lack of moral empathy. Across the political spectrum, we’re unable to get inside the mindset of people who expresses views that we disagree with, and see the issue from their point of view.

A common cause of conflict, as above, is confusion between personal preferences and moral positions. Assuming good faith on the part of the person you disagree with, and actually engaging with the beliefs they claim to hold, is perhaps the best remedy for our inability to make progress on controversial issues.

One seeming path to progress involves contraception. A lot of people who are anti-abortion are also anti-contraception. But they’ll usually think that abortion is much worse than contraception – so why can’t we compromise and agree to have much more contraception available?

According to Amanda, a charitable explanation is that people who are anti-abortion and anti-contraception engage in moral reasoning and advocacy based on what, in their minds, is the best of all possible worlds: one where people neither use contraception nor get abortions.

So instead of arguing about abortion and contraception, we could discuss the underlying principle that one should advocate for the best possible world, rather than the best probable world. Successfully break down such ethical beliefs, absent political toxicity, and it might be possible to actually figure out why we disagree and perhaps even converge on agreement.

Today’s episode blends such practical topics with cutting-edge philosophy. We cover:

  • The problem of ‘moral cluelessness’ – our inability to predict the consequences of our actions – and how we might work around it
  • Amanda’s biggest criticisms of social justice activists, and of critics of social justice activists
  • Is there an ethical difference between prison and corporal punishment? Are both or neither justified?
  • How to resolve ‘infinitarian paralysis’ – the inability to make decisions when infinities get involved.
  • What’s effective altruism doing wrong?
  • How should we think about jargon? Are a lot of people who don’t communicate clearly just trying to scam us?
  • How can people be more successful while they remain within the cocoon of school and university?
  • How did Amanda find her philosophy PhD, and how will she decide what to do now?
