Is There An Illusion Of Moral Decline?
[Epistemic status: very uncertain about Part II; more convinced about Part III] I. This is the big question in the paper du jour, The Illusion Of Moral Decline, by Mastroianni and Gilbert (from here on: MG). It goes like this: people say that morality is declining. We know this because one million polls have asked people “do you think morality is declining?” and people always answer yes. MG go over these one million polls, do statistics to them, and find that people definitely think that morality is declining. People have thought this since at least 1949, when the first good polls were run - but realistically much longer. This could be (they say) either because morality is actually declining, or because of a bias. They argue that morality is not actually declining. In support, they marshal many polls asking questions like “Do you think most people are honest?” or “Do you think people treat you with respect?” and find that the answers mostly stay the same. Might this be because of definition creep - eg might people define “honest” relative to expectations, and expectations lower as morality declines? In order to rule this out, MG look at various objective questions that they think bear on morality, like “have you been mugged/assaulted recently?” or “have you donated blood in the past year?” They find that all of these have also stayed the same. Therefore, both people’s subjective impressions of morality, and more objective proxies for social morality, have stayed the same. Therefore, morality is not actually declining. Therefore there must be a bias. https://astralcodexten.substack.com/p/is-there-an-illusion-of-moral-decline

Sure, Whatever, Let's Try Another Contra Caplan On Mental Illness
I. Bryan Caplan thinks he’s debating me about mental illness. He’s not. Sometimes he posts some thoughts he has been having about mental illness, with or without a sentence saying “this is part of my debate with Scott”. Then I write a very long essay explaining why he is wrong. Then he ignores it, and has more thoughts, and again writes them up with “this is part of my debate with Scott”. I would not describe this as debating. Call it unibating, or monobating, or another word ending in -bating which is less polite but as far as I can tell equally appropriate. Although he doesn’t answer my rebuttals, he does diligently respond to various unrelated posts of mine, explaining why they must mean I am secretly admitting he was right all along. When I wrote about the scourge of witches stealing people’s penises, Caplan spun it as me secretly admitting he was right all along about mental illness. Sometimes I feel like this has gone a bit too far - when I announced I had gotten married, Caplan spun it as me secretly admitting he was right all along about mental illness. Let it be known to all that I am never secretly admitting Bryan Caplan is right about mental illness. There is no further need to speculate that I am doing this. If you want to know my position vis-a-vis Bryan Caplan and mental illness, you are welcome to read my four thousand word essay on the subject, Contra Contra Contra Caplan On Psych. You will notice that the title clearly telegraphs that it is about Bryan Caplan and mental illness, and that (if you count up the contras) I am against him. If that ever changes, rest assured I will telegraph it in something titled equally clearly. https://astralcodexten.substack.com/p/sure-whatever-lets-try-another-contra

Every Flashing Element On Your Site Alienates And Enrages Users
Warning: This post might give vulnerable people new sensory sensitivities Everyone hates flashing banner ads, but maybe they’re a necessary evil. Creators want money, advertisers demand a certain level of visibility for their ad buys, maybe sites are willing to eat the cost in user goodwill. Fine. But what’s everyone else’s excuse? https://astralcodexten.substack.com/p/every-flashing-element-on-your-site

"Through A Glass Darkly" In Asterisk Magazine
(Includes full article narration.) I have an article summarizing attempts to forecast AI progress, including a five year check-in on the predictions in Grace et al (2017). It’s not here, it's at asteriskmag.com, a rationalist / effective altruist magazine: Through A Glass Darkly. This is their AI issue (it’s not always so AI focused). https://astralcodexten.substack.com/p/through-a-glass-darkly-in-asterisk

Your Book Review: Public Citizens
[This is one of the finalists in the 2023 book review contest, written by an ACX reader who will remain anonymous until after voting is done. I’ll be posting about one of these a week for several months. When you’ve read them all, I’ll ask you to vote for a favorite, so remember which ones you liked] I. Today, pundits across the political spectrum bemoan America’s inability to build. Across the country, NIMBYs and status-quo defenders exploit procedural rules to block new development, giving us a world where it takes longer to get approval for a single new building in San Francisco than it did to build the entire Empire State Building, where so-called “environmental review” is weaponized to block even obviously green initiatives like solar panels, and where new public works projects are completed years late and billions over budget—or, like California’s incredible shrinking high-speed rail, may never be completed at all. Inevitably, such a complex set of dysfunctions must have an equally complex set of causes. It took us decades to get into this mess, and just as there’s no one simple fix, there’s no one simple inflection point in our history on which we can place all the blame. But what if there was? What if there was, in fact, a single person we could blame for this entire state of affairs, a patsy from the past at whom we could all point our censorious fingers and shout, “It’s that guy’s fault!” There is such a person, suggests history professor Paul Sabin in his new book Public Citizens: The Attack on Big Government and the Remaking of American Liberalism. And he isn’t isn’t a mustache-twirling villain—he’s a liberal intellectual. If you know him for anything, it’s probably for being the reason you know what a hanging chad is. That’s right: it’s all Ralph Nader’s fault. https://astralcodexten.substack.com/p/your-book-review-public-citizens

Davidson On Takeoff Speeds
Machine Alignment Monday 6/19/23 The face of Mt. Everest is gradual and continuous; for each point on the mountain, the points 1 mm away aren’t too much higher or lower. But you still wouldn’t want to ski down it. I thought about this when reading What A Compute-Centric Framework Says About Takeoff Speeds, by Tom Davidson. Davidson tries to model what some people (including me) have previously called “slow AI takeoff”. He thinks this is a misnomer. Like skiing down the side of Mount Everest, progress in AI capabilities can be simultaneously gradual, continuous, fast, and terrifying. Specifically, he predicts it will take about three years to go from AIs that can do 20% of all human jobs (weighted by economic value) to AIs that can do 100%, with significantly superhuman AIs within a year after that. As penance for my previous mistake, I’ll try to describe Davidson’s forecast in more depth. https://astralcodexten.substack.com/p/davidson-on-takeoff-speeds

Your Book Review: Njal’s Saga
Finalist #5 in the Book Review Contest [This is one of the finalists in the 2023 book review contest, written by an ACX reader who will remain anonymous until after voting is done. I’ll be posting about one of these a week for several months. When you’ve read them all, I’ll ask you to vote for a favorite, so remember which ones you liked] I. I found Njal’s Saga hard to follow. Halfway through, a friend reassured me it wasn’t my fault. The medieval Icelanders had erred in releasing it as a book. It should have been the world’s wackiest Phoenix Wright: Ace Attorney spinoff. Remember, medieval Iceland was an early attempt at anarcho-capitalist utopia. When Harald Fairhair declared himself King of Norway, the Norwegians who refused to bend the knee fled west to build a makeshift seastead on a frozen volcanic island. No lords, no kings, no masters. Only lawsuits. So, so many lawsuits. Once a year, the Icelanders would meet at the Althing, a free-for-all open-air law court. There they would engage in that most Viking of pastimes - suing each other, ad nauseam, for every minor slight of the past six months. Offended parties would sell their rights to prosecute a case to the highest bidder, who would go around seeking fair arbitrators (or, in larger cases, defer to a panel chosen by chieftain-nobles called godi. Courts would propose a penalty for the losing side - usually money. There were no police, but if the losers refused to pay, the courts could declare them “outlaws” - in which case it was legal to kill them. If you wanted to be a Viking in medieval Iceland, you needed a good lawyer. And Njal was the greatest lawyer of all. https://astralcodexten.substack.com/p/your-book-review-njals-saga

Your Incentives Are Not The Same As Media Companies'
Unfortunately I hate many of you. Only the ones with Twitter accounts. If you don’t have one of those, you’re fine. But if you do have one, there’s a good chance you said something which horribly offended me. You said everyone who believed X was an idiot and a Nazi, and I believed X. You read the title but not the body of an article about some group I care about, and viciously insulted them based on your misunderstanding of their position. You spent five seconds thinking of a clever dunk on someone who happened to be a friend of mine trying really hard to make the world better, and ruined their day. https://astralcodexten.substack.com/p/your-incentives-are-not-the-same

The Canal Papers
You know all the stuff we’ve been talking about here the past few years - mental mountains, trapped priors, relaxed beliefs under psychedelics? The new keyword for all of that is “canalization”. At least that’s what I gather from a giant paper recently published by some of the leading thinkers in computational psychiatry (Karl Friston, Robin Carhart-Harris, etc). A quick review: you can model the brain as an energy landscape . . . . . . with various peaks and valleys in some multidimensional space Situations and stimuli plant “you” at some point on the landscape, and then you “roll down” towards some local minimum. If you’re the sort of person who repeats “I hate myself, I hate myself” in a lot of different situations, then you can think of the action of saying “I hate myself” as an attractor - a particularly steep, deep valley which it’s easy to fall into and hard to get out of. Many situations are close to the slopes of the “I hate myself” valley, so it’s easy to roll down and get caught there. What are examples of valleys other than saying “I hate myself”? The authors suggest habits. If you always make the sign of the cross when passing a graveyard, there’s a steep slope from the situation of passing a graveyard to the action of signing the cross. We can be even broader: something really basic like edge-detection in the visual system is a valley. When you see a scene, you almost always want to automatically do edge-detection on it. Walking normally is a valley; there’s a certain correct sequence of muscle movements, and you don’t want to start rotating your ligaments in some weird direction halfway through. https://astralcodexten.substack.com/p/the-canal-papers tt
