The Reversal Test: Eliminating Status Quo Bias in Applied Ethics

We present a heuristic for correcting for one kind of bias (status quo bias), which we suggest affects many of our judgments about the consequences of modifying human nature. We apply this heuristic to the case of cognitive enhancements, and argue that the consequentialist case for this is much stronger than commonly recognized.

Astronomical Waste: The Opportunity Cost of Delayed Technological Development

Suns are illuminating and heating empty rooms, unused energy is being flushed down black holes, and our great common endowment of negentropy is being irreversibly degraded into entropy on a cosmic scale. These are resources that an advanced civilization could have used to create value-structures, such as sentient beings living worthwhile lives...

Infinite Ethics

Cosmology shows that we might well be living in an infinite universe that contains infinitely many happy and sad people. Given some assumptions, aggregative ethics implies that such a world contains an infinite amount of positive value and an infinite amount of negative value. But you can presumably do only a finite amount of good or bad. Since an infinite cardinal quantity is unchanged by the addition or subtraction of a finite quantity, it looks as though you can't change the value of the world. Aggregative consequentialism (and many other important ethical theories) are threatened by total paralysis. We explore a variety of potential cures, and discover that none works perfectly and all have serious side-effects. Is aggregative ethics doomed?

The Unilateralist's Curse: The Case for a Principle of Conformity

In cases where several altruistic agents each have an opportunity to undertake some initiative, a phenomenon arises that is analogous to the winner's curse in auction theory. To combat this problem, we propose a principle of conformity. It has applications in technology policy and many other areas.

Dignity and Enhancement

Does human enhancement threaten our dignity as some have asserted? Or could our dignity perhaps be technologically enhanced? After disentangling several different concepts of dignity, this essay focuses on the idea of dignity as a quality (a kind of excellence admitting of degrees). The interactions between enhancement and dignity as a quality are complex and link into fundamental issues in ethics and value theory.

Risk & The Future

Existential Risk Reduction as Global Priority

Existential risks are those that threaten the entire future of humanity. This paper elaborates the concept of existential risk and its relation to basic issues in axiology and develops an improved classification scheme for such risks. It also describes some of the theoretical and practical challenges posed by various existential risks and suggests a new way of thinking about the ideal of sustainability.

The Future of Human Evolution

This paper explores some dystopian scenarios where freewheeling evolutionary developments, while continuing to produce complex and intelligent forms of organization, lead to the gradual elimination of all forms of being worth caring about. We then discuss how such outcomes could be avoided and argue that under certain conditions the only possible remedy would be a globally coordinated effort to control human evolution by adopting social policies that modify the default fitness function of future life forms.

Existential Risks: Analyzing Human Extinction Scenarios and Related Hazards

Existential risks are ways in which we could screw up badly and permanently. Remarkably, relatively little serious work has been done in this important area. The point, of course, is not to welter in doom and gloom but to better understand where the biggest dangers are so that we can develop strategies for reducing them.

Are You Living in a Computer Simulation?

This paper argues that at least one of the following propositions is true: (1) the human species is very likely to go extinct before reaching the posthuman stage; (2) any posthuman civilization is extremely unlikely to run significant number of simulations or (variations) of their evolutionary history; (3) we are almost certainly living in a computer simulation. It follows that the naïve transhumanist dogma that there is a significant chance that we will one day become posthumans who run ancestor-simulations is false, unless we are currently living in a simulation. A number of other consequences of this result are also discussed.

Anthropics & Probability

Anthropic Bias: Observation Selection Effects in Science and Philosophy

Failure to consider observation selection effects result in a kind of bias that infest many branches of science and philosophy. This book presented the first mathematical theory for how to correct for these biases. It also discusses some implications for cosmology, evolutionary biology, game theory, the foundations of quantum mechanics, the Doomsday argument, the Sleeping Beauty problem, the search for extraterrestrial life, the question of whether God exists, and traffic planning.

Anthropic Shadow: Observation Selection Effects and Human Extinction Risks

"Anthropic shadow" is an observation selection effect that prevent observers from observing certain kinds of catastrophes in their recent geological and evolutionary past. We risk underestimating the risk of catastrophe types that lie in this shadow.

A Primer on the Doomsday argument

The Doomsday argument purports to prove, from basic probability theory and a few seemingly innocuous empirical premises, that the risk that our species will go extinct soon is much greater than previously thought. My view is that the Doomsday argument is inconclusive - although not for any trivial reason. In my book, I argued that a theory of observation selection effects is needed to explain where it goes wrong.

Sleeping Beauty and Self-Location: A Hybrid Model

The Sleeping Beauty problem is an important test stone for theories about self-locating belief. I argue against both the traditional views on this problem and propose a new synthetic approach.

Cars In the Other Lane Really Do Go Faster

When driving on the motorway, have you ever wondered about (and cursed!) the fact that cars in the other lane seem to be getting ahead faster than you?

But there is an alternative explanation, based on observational selection effects...

Philosophy of Mind

Quantity of Experience: Brain-Duplication and Degrees of Consciousness

If two brains are in identical states, are there two numerically distinct phenomenal experiences or only one? Two, I argue. But what happens in intermediary cases? This paper looks in detail at this question and suggests that there can be a fractional (non-integer) number of qualitatively identical experiences. This has implications for what it is to implement a computation and for Chalmer's Fading Qualia thought experiment.

Decision Theory

Bio

Nick Bostrom is Professor at Oxford University, where he is the founding Director of the Future of Humanity Institute. He also directs the Strategic Artificial Intelligence Research Center. He is the author of some 200 publications, including Anthropic Bias (Routledge, 2002), Global Catastrophic Risks (ed., OUP, 2008), Human Enhancement (ed., OUP, 2009), and Superintelligence: Paths, Dangers, Strategies (OUP, 2014), a New York Times bestseller. He is best known for his work in five areas: (i) existential risk; (ii) the simulation argument; (iii) anthropics; (iv) impacts of future technology, especially machine intelligence; and (v) macrostrategy (links between present actions and long-term outcomes).

Bostrom has a background in physics, computational neuroscience, and mathematical logic as well as philosophy. He is recipient of a Eugene R. Gannon Award (one person selected annually worldwide from the fields of philosophy, mathematics, the arts and other humanities, and the natural sciences). He has been listed on Foreign Policy's Top 100 Global Thinkers list twice; and he was included on Prospect magazine's World Thinkers list, the youngest person in the top 15 from all fields and the highest-ranked analytic philosopher. His writings have been translated into 24 languages. There have been more than 100 translations and reprints of his works.

Crucial Considerations

A thread that runs through my work is a concern with "crucial considerations". A crucial consideration is an idea or argument that might plausibly reveal the need for not just some minor course adjustment in our practical endeavours but a major change of direction or priority.

If we have overlooked even just one such consideration, then all our best efforts might be for naughtor less. When headed the wrong way, the last thing needed is progress. It is therefore important to pursue such lines of inquiry as might disclose an unnoticed crucial consideration.

Some of the relevant inquiries are about moral philosophy and values. Others have to do with rationality and reasoning under uncertainty. Still others pertain to specific issues and possibilities, such as existential risks, the simulation hypothesis, human enhancement, infinite utilities, anthropic reasoning, information hazards, the future of machine intelligence, or the singularity hypothesis.

High-leverage questions associated with crucial considerations deserve to be investigated. My research interests are quite wide-ranging; yet they all stem from the quest to understand the big picture for humanity, so that we can more wisely choose what to aim for and what to do. Embarking on this quest has seemed the best way to try to make a positive contribution to the world.

Background

I was born in Helsingborg, Sweden, and grew up by the seashore. I was bored in school. At age fifteen or sixteen I had an intellectual awakening, and feeling that I had wasted the first one and a half decades of my life, I resolved to focus on what was important. Since I did not know what was important, and I did not know how to find out, I decided to start by trying to place myself in a better position to find out. So I began a project of intellectual self-development, which I pursued with great intensity for the next one and a half decades.

As an undergraduate, I studied many subjects in parallel, and I gather that my performance set a national record. I was once expelled for studying too much, after the head of Umeå University psychology department discovered that I was concurrently following several other full-time programs of study (physics, philosophy, and mathematical logic), which he believed to be psychologically impossible.

For my postgraduate work, I went to London, where I studied physics and neuroscience at King's College, and obtained a PhD from the London School of Economics. For a while I did a little bit stand-up comedy on the vibrant London pub and theatre circuit.

During those years, I co-founded, with David Pearce, the World Transhumanist Association, a nonprofit grassroots organization. Later, I was involved in founding the Institute for Ethics and Emerging Technologies, a nonprofit virtual think tank. The objective was to stimulate wider discussion about the implications of future technologies, in particular technologies that might lead to human enhancement. (These organizations have since developed on their own trajectories, and it is very much not the case that I agree with everything said by those who flock under the transhumanist flag.)

Since 2006, I've been the founding director of the Future of Humanity Institute at Oxford University. This unique multidisciplinary research aims to enable a select set of intellects to apply careful thinking to big-picture question for humanity and global priorities. The Institute belongs to the Faculty of Philosophy and the Oxford Martin School. Since 2015, I also direct the Strategic Artificial Intelligence Research Center.

I am in a very fortunate position. I have no teaching duties. I am supported by a staff of assistants and brilliant research fellows. There are virtually no restrictions on what I can work on. I must try very hard to be worthy of this privilege and to cast some light on matters that matter.
