    #76 (Bonus) - Is P(doom) meaningful? Debating epistemology (w/ Liron Shapira)

    Liron Shapira, host of [Doom Debates], invited us on to discuss Popperian versus Bayesian epistemology and whether we're worried about AI doom. As one might expect knowing us, we only got about halfway through the first subject, so get yourselves ready (presumably with many drinks) for part II in a few weeks! The era of Ben and Vaden's rowdy youtube debates has begun. Vaden is jubilant, Ben is uncomfortable, and the world has never been more annoyed by Popperians. Follow Liron on twitter (@liron) and check out the Doom Debates youtube channel and podcast. We discuss Whether we're concerned about AI doom Bayesian reasoning versus Popperian reasoning Whether it makes sense to put numbers on all your beliefs Solomonoff induction Objective vs subjective Bayesianism Prediction markets and superforecasting References Vaden's blog post on Cox's Theorem and Yudkowsky's claims of "Laws of Rationality": https://vmasrani.github.io/blog/2021/the_credence_assumption/ Disproof of probabilistic induction (including Solomonov Induction): https://arxiv.org/abs/2107.00749 EA Post Vaden Mentioned regarding predictions being uncalibrated more than 1yr out: https://forum.effectivealtruism.org/posts/hqkyaHLQhzuREcXSX/data-on-forecasting-accuracy-across-different-time-horizons#Calibrations Article by Gavin Leech and Misha Yagudin on the reliability of forecasters: https://ifp.org/can-policymakers-trust-forecasters/ Superforecaster p(doom) is ~1%: https://80000hours.org/2024/09/why-experts-and-forecasters-disagree-about-ai-risk/#:~:text=Domain%20experts%20in%20AI%20estimated,by%202100%20(around%2090%25).

    #75 - The Problem of Induction, Relitigated (w/ Tamler Sommers)

    When Very Bad Wizards meets Very Culty Popperians. We finally decided to have a real life professional philosopher on the pod to call us out on our nonsense, and are honored to have on Tamler Sommers, from the esteemed Very Bad Wizards podcast, to argue with us about the Problem of Induction. Did Popper solve it, or does his proposed solution, like all the other attempts, "fail decisively"? (Warning: One of the two hosts maaay have revealed their Popperian dogmatism a bit throughout this episode. Whichever host that is - they shall remain unnamed - apologizes quietly and stubbornly under their breath.) Check out Tamler's website, his podcast (Very Bad Wizards), or follow him on twitter (@tamler). We discuss What is the problem of induction? Whether regularities really exist in nature The difference between certainty and justification Popper's solution to the problem of induction If whiskey will taste like orange juice next week What makes a good theory? Why prediction is secondary to explanation for Popper If science and meditiation are in conflict The boundaries of science References Very Bad Wizards episode on induction The problem of induction, by Wesley Salmon Hume on induction Errata Vaden mentions in the episode how "Einstein's theory is better because it can explain earth's gravitational constant". He got some of the details wrong here - it's actually the inverse square law, not the gravitational constant. Listen to Edward Witten explain it much better here.

    #74 - Disagreeing about Belief, Probability, and Truth (w/ David Deutsch)

    What do you do when one of your intellectual idols comes on the podcast? Bombard them with disagreements of course. We were thrilled to have David Deutsch on the podcast to discuss whether the concept of belief is a useful lens on human cognition, when probability and statistics should be deployed, and whether he disagrees with Karl Popper on abstractions, the truth, and nothing but the truth. Follow David on Twitter (@DavidDeutschOxf) or find his website here. We discuss Whether belief is a fruitful lens through which to analyze ideas Whether a non-quantitative form of belief can be defended How does belief bottom out epistemologically? Whether statistics and probability are useful Where should statistics and probability be used in practice? The Popper-Miller theorem Statements vs propositions and their relevance for truth Whether Popper and Deutsch disagree about truth References The Popper-Miller theorem.

    #73 - The Unfairness of Proportional Representation

    Want to make everyone under 30 extremely angry? Tell them you don't like proportional representation. Tell them proportional representation sucks, just like recycling. In this episode, we continue to improve your popularity at parties by diving into Sir Karl's theory of democracy, and his arguments for why the first-past-the-post electoral system is superior to proportional representation systems. And if you find anyone left at the party who still wants to talk to you, we also cover Chapter 13 of Beginning of Infinity, where Deutsch builds upon Popper's theory. And always remember, First-Past-The-Post: If it's good enough for the horses, it's good enough for us. We discuss Why democracy should be about the removal of bad leaders How Popper's conception of democracy differs from the usual conception Why Popper supports first-past-the-post (FPP) over proportional representation (PR) How PR encourages backroom dealing and magnifies the influence of unpopular leaders The sensitivity of FPP to changes to popular will How FPP makes it easier to obtain majorities How majorities make it easier to trace the consequences of policies Deutsch and his criticism of compromise-policies.

    27 DE AGO.

    #72 (C&R, Chap. 19: Part II) - On the (alleged) Right of a Nation to Self-Determination

    Part two on Chapter 19 of Conjectures and Refutations! Last time we got a little hung up arguing about human behavior and motivations. Putting that disagreement aside, like mature adults, we move on to the rest of the chapter and Popper's remaining theses. In particular, we focus on Popper's criticism of the idea of a nation's right to self-determination. Things were going smoothly ... until roughly five minutes in, when we start disagreeing about what the "nation" in "nation state" actually means. (Note: Early listeners of this episode have commented that this one is a bit hard to follow - highly suggest reading the text to compensate for our many confusing digressions. Our bad, our bad). We discuss Are there any benefits of being bilingual? Popper's attack on the idea of national self-determination Popper's second thesis: that out own free world is by far the best society thus far Reductions in poverty, unemployment, sickness, pain, cruelty, slavery, discrimination, class differences Popper's third thesis: The relation of progress to war Whether Popper was factually correct about his claim that democracies do not wage wars of aggression Self-accusation: A unique feature to Western societies Popper's fourth thesis about the power of ideas And his fifth thesis that truth is hard to come by References Conjectures and Refutations Definition of self-determination from Cornell Law School The UN Charter Wilson's 14 Points Quotes The absurdity of the communist faith is manifest. Appealing to the belief in human freedom, it has produced a system of oppression without parallel in history. But the nationalist faith is equally absurd. I am not alluding here to Hitler’s racial myth. What I have in mind is, rather, an alleged natural right of man— the alleged right of a nation to self-determination. That even a great humanitarian and liberal like Masaryk could uphold this absurd- ity as one of the natural rights of man is a sobering thought. It suffices to shake one’s faith in the wisdom of philosopher kings, and it should be contemplated by all who think that we are clever but wicked rather than good but stupid. For the utter absurdity of the principle of national self-determination must be plain to anybody who devotes a moment’s effort to criticizing it. The principle amounts to the demand that each state should be a nation-state: that it should be confined within a natural border, and that this border should coincide with the location of an ethnic group; so that it should be the ethnic group, the ‘nation’, which should determine and protect the natural limits of the state. But nation-states of this kind do not exist. Even Iceland—the only exception I can think of—is only an apparent exception to this rule. For its limits are determined, not by its ethnic group, but by the North Atlantic—just as they are protected, not by the Icelandic nation, but by the North Atlantic Treaty. Nation-states do not exist, simply because the so-called ‘nations’ or ‘peoples’ of which the nationalists dream do not exist. There are no, or hardly any, homogenous ethnic groups long settled in countries with natural borders. Ethnic and linguistic groups (dialects often amount to linguistic barriers) are closely intermingled everywhere. Masaryk’s Czechoslovakia was founded upon the principle of national self-determination. But as soon as it was founded, the Slovaks demanded, in the name of this principle, to be free from Czech domination; and ultimately it was destroyed by its German minority, in the name of the same principle. Similar situations have arisen in practically every case in which the principle of national self- determination has been applied to fixing the borders of a new state: in Ireland, in India, in Israel, in Yugoslavia. There are ethnic minorities everywhere. The proper aim cannot be to ‘liberate’ all of them; rather, it must be to protect all of them. The oppression of national

    #71 (C&R, Chap 19: Part I) - The History of Our Time: An Optimist's View

    Back to the Conjectures and Refutations series, after a long hiatus! Given all that's happening in the world and the associated rampant pessimism, we thought it would be appropriate to tackle Chapter 19 - A History of Our Time: An Optimist's View. We get through a solid fifth of the chapter, at which point Ben and Vaden start arguing about whether people are fundamentally good, fundamentally bad, or fundamentally driven by signalling and incentives. And we finally answer the all-important question on everyone's mind: Does Adolf Eichmann support defunding the police? Banal Lives Matter. We discuss Thoughts on the recent Trump assasination attempt How can Popper be an optimist with prophesying about the future? The scarcity value of optimism Russell's view that our intellectual development has outrun our moral development Relationship of this view to the orthogonality thesis Popper's competing view that our troubles arise because we are good but stupid How much can incentives compel us to do bad things? How easy it for humans to really be led by the nose Ben's experience during the summer of 2020 References Conjectures and Refutations Orthogonality thesis Eichmann in Jerusalem by Hannah Arendt Adam Smith's thought experiment about losing a pinky Radiolab episode, "The Bad Show" Quotes Now I come to the word ‘Optimist’. First let me make it quite clear that if I call myself an optimist, I do not wish to suggest that I know anything about the future. I do not wish to pose as a prophet, least of all as a historical prophet. On the contrary, I have for many years tried to defend the view that historical prophecy is a kind of quackery. I do not believe in historical laws, and I disbelieve especially in anything like a law of progress. In fact, I believe that it is much easier for us to regress than to progress. Though I believe all this, I think that I may fairly describe myself as an optimist. For my optimism lies entirely in my interpretation of the present and the immediate past. It lies in my strongly appreciative view of our own time. And whatever you might think about this optimism you will have to admit that it has a scarcity value. In fact the wailings of the pessimists have become somewhat monotonous. No doubt there is much in our world about which we can rightly complain if only we give our mind to it; and no doubt it is sometimes most important to find out what is wrong with us. But I think that the other side of the story might also get a hearing. And whatever you might think about this optimism you will have to admit that it has a scarcity value. In fact the wailings of the pessimists have become somewhat monotonous. No doubt there is much in our world about which we can rightly complain if only we give our mind to it; and no doubt it is sometimes most important to find out what is wrong with us. But I think that the other side of the story might also get a hearing. We have become very clever, according to Russell, indeed too clever. We can make lots of wonderful gadgets, including television, high-speed rockets, and an atom bomb, or a thermonuclear bomb, if you prefer. But we have not been able to achieve that moral and political growth and maturity which alone could safely direct and control the uses to which we put our tremendous intellectual powers. This is why we now find ourselves in mortal danger. Our evil national pride has prevented us from achieving the world-state in time.To put this view in a nutshell: we are clever, perhaps too clever, but we are also wicked; and this mixture of cleverness and wickedness lies at the root of our troubles. My first thesis is this. We are good, perhaps a little too good, but we are also a little stupid; and it is this mixture of goodness and stupidity which lies at the root of our troubles. The main troubles of our time—and I do not deny that we live in troubled times—are not due to our moral wickedness, but, on the contrary, to our

    #70 - ... and Bayes Bites Back (w/ Richard Meadows)

    Sick of hearing us shouting about Bayesianism? Well today you're in luck, because this time, someone shouts at us about Bayesianism! Richard Meadows, finance journalist, author, and Ben's secretive podcast paramour, takes us to task. Are we being unfair to the Bayesians? Is Bayesian rationality optimal in theory, and the rest of us are just coping with an uncertain world? Is this why the Bayesian rationalists have so much cultural influence (and money, and fame, and media attention, and ...), and we, ahem, uhhh, don't? Check out Rich's website, his book Optionality: How to Survive and Thrive in a Volatile World, and his podcast. We discuss The pros of the rationality and EA communities Whether Bayesian epistemology contributes to open-mindedness The fact that evidence doesn't speak for itself The fact that the world doesn't come bundled as discrete chunks of evidence Whether Bayesian epistemology would be "optimal" for Laplace's demon The difference between truth and certainty Vaden's tone issues and why he gets animated about this subject.
