By far the greatest danger of Artificial Intelligence is that people conclude too early that they understand it. This text helps you to understand how little we might understand about AI.

In late 2008, economist Robin Hanson and AI theorist Eliezer Yudkowsky conducted an online debate about the future of artificial intelligence, and in particular about whether generally intelligent AIs will be able to improve their own capabilities very quickly (a.k.a. “foom”). The original debate took place in a long series of blog posts, which are collected here. This book also includes a transcript of a 2011 in-person debate between Hanson and Yudkowsky on this subject, a summary of the debate written by Kaj Sotala, and a 2013 technical report on AI takeoff dynamics (“intelligence explosion microeconomics”) written by Yudkowsky.

"You wouldn't expect that a man of such great power and wickedness would be in the business of helping any person who requested it. But whether it makes any sense or not, that's the reputation the Dark Lord If you approach the Dark Lord for help, he'll give you an answer and your goal will be achieved. The price is that his answer might violate the rules of righteous conduct. To put it another way, he's like an ancient wisewoman who lives in a high mountain cave and speaks in riddles, except that he's a villainous lord." The country of Santal is perishing, and nobody knows why. His country's plight has driven Prince Nama over far roads to consult the famed Dark Lord for answers. On arriving there, he finds a mightily muscled sage in black armor, just as the stories say. And, chained to the Dark Lord's throne, a mysterious slave-woman with round ears. Round ears? There's nowhere in the world where people have round ears, is there? Content sexual abuse, economics.

When should you think that you may be able to do something unusually well?

Whether you’re trying to outperform in science, or in business, or just in finding good deals on eBay, it’s important that you have a sober understanding of your relative competencies.

The story only ends there, however, if you’re fortunate enough to live in an adequate civilization.

Eliezer Yudkowsky’s Inadequate Equilibria is a sharp and lively guidebook for anyone questioning when and how they can know better, and do better, than the status quo. Freely mixing debates on the foundations of rational decision-making with tips for everyday life, Yudkowsky explores the central question of when we can (and can’t) expect to spot systemic inefficiencies, and exploit them.

"My family name is Yugano. My given name is Yuuki. I have no redeeming qualities." So begins this light novel of a girl corrupted by the Internet, and then summoned to another world. She's jaded from having already read many stories like that - but will that prepare her for what awaits in this world? Of course not! But she's going to plunge ahead anyway, and not slow down for anything!Eliezer Yudkowsky is the author of "Harry Potter and the Methods of Rationality" and " From AI to Zombies". He is a decision theorist specializing in self-reference and reflection, a fact which unstoppably infects his writing no matter how frivolous.

What does it actually mean to be rational? Not Hollywood-style "rational," where you forsake all human feeling to embrace Cold Hard Logic. Real rationality, of the sort studied by psychologists, social scientists, and mathematicians. The kind of rationality where you make good decisions, even when it's hard; where you reason well, even in the face of massive uncertainty; where you recognize and make full use of your fuzzy intuitions and emotions, rather than trying to discard them.

In "Rationality: From AI to Zombies," Eliezer Yudkowsky explains the science underlying human irrationality with a mix of fables, argumentative essays, and personal vignettes. These eye-opening accounts of how the mind works (and how, all too often, it doesn't!) are then put to the test through some genuinely difficult puzzles: computer scientists' debates about the future of artificial intelligence (AI), physicists' debates about the relationship between the quantum and classical worlds, philosophers' debates about the metaphysics of zombies and the nature of morality, and many more. In the process, "Rationality: From AI to Zombies" delves into the human significance of correct reasoning more deeply than you'll find in any conventional textbook on cognitive science or philosophy of mind.

A decision theorist and researcher at the Machine Intelligence Research Institute, Yudkowsky published earlier drafts of his writings to the websites Overcoming Bias and Less Wrong. "Rationality: From AI to Zombies" compiles six volumes of Yudkowsky's essays into a single electronic tome. Collectively, these sequences of linked essays serve as a rich and lively introduction to the science—and the art—of human rationality.

Three Worlds Collide is a story I wrote to illustrate some points on naturalistic metaethics and diverse other issues of rational conduct. It grew, as such things do, into a small novella. On publication, it proved widely popular and widely criticized. Be warned that the story, as it wrote itself, ended up containing some profanity and PG-13 content.

Harry Potter and the Methods of Rationality is a work of alternate-universe Harry Potter fan-fiction wherein Petunia Evans has married an Oxford biochemistry professor and young genius Harry grows up fascinated by science and science fiction. When he finds out that he is a wizard, he tries to apply scientific principles to his study of magic, with sometimes surprising results.

If you live in an urban area, you probably don’t need to walk very far to find a martial arts dojo.Why aren’t there dojos that teach rationality?Very recently—in just the last few decades—the human species has acquired a great deal of new knowledge about human rationality. Experimental investigations of empirical human psychology; and theoretical probability theory to interpret what our experiments tell us; and evolutionary theory to explain the conclusions. These fields give us new focusing lenses through which to view the landscape of our own minds. We have a shared vocabulary in which to describe problems and solutions. Humanity may finally be ready to synthesize the martial art of mind: to refine, share, systematize, and pass on techniques of personal rationality.When human brains try to do things, they can run into some very strange problems. Self-deception, confirmation bias, magical thinking—it sometimes seems our ingenuity is boundless when it comes to shooting ourselves in the foot.In Map and Territory, decision theorist Eliezer Yudkowsky asks what a “martial art” of rationality would look like, beginning with the basic fighting stance—the orientation toward the world that lets us get the most bang for our cognitive buck, that best positions us to understand and react to brains’ strange acts of self-destruction.

How to Actually Change Your Mind is the second book contained in the ebook Rationality: From AI to Zombies, by Eliezer Yudkowsky. It is the edited version of a series of blog posts in "the Sequences", and covers the ultra-high-level penultimate technique of rationality: triumphing over confirmation bias and motivated cognition.
How to Actually Change Your Mind contains seven sequences of essays. These are all collected in the Rationality: From AI to Zombies ebook, but the essay names below are also linked to the original blog posts.
The previous book in the series is Map and Territory, and the next book is The Machine in the Ghost.
