It seems like the current crypto market may be a giant fraud.
This fits my mildly informed blockchain scepticism. I see few legitimate use cases. I’m not alone
I’ve never seen so many people searching so hard for a problem to go with their solution.
Blockchain is a cool technology, but mostly malign. As an article I read a couple of years ago (and can’t find) notes, it’s broken by design: a solution to a post-apocalyptic world where there are no trusted institutions. But the whole of civilization is building trusted institutions.
Found it! Kai Stinchcombe argues blockchain is “Somalia on purpose”. I’d say “dystopian by design”.
On top of that, the most popular algorithms are an environmental disaster, and this has been known for years. CO2 emissions from bitcoin mining offset greenhouse-gas reductions from the Paris treaty. They are at least 100,000x less efficient than normal visa transactions.
Just capturing a facebook post (screenshot) - I went into the internet archive to see what used to be on antifa dot com and when it started redirecting. The q folks of course see the redirect as strong evidence of some nefarious conspiracy. So, thoughts in screenshot.

I notice qnonymous.org is available cheap. If I made that point to whitehouse.gov, …. well probably no one would care. If they did care, the net effect would just increase total agitation, rather than to serve as a reductio. Unhelpful. Besides, if you start from the premise that the world is absurd, then a reductio loses its force.
But perhaps the best reason not to do this is that it does not arise from a principle of charity. On which point, why the original post?
What would happen if the Dems made a strategic compromise on Roe v Wade? If you were Biden, what would you offer, and what require in exchange? If the deal happened as you describe, would that be a gain or loss in next election(s)?
Question inspired by this piece in America, and thinking over a Biden priority tradeoffs essay by Paul Monk.
Wrong About
The winner of the Metaculus Li-Wenliang COVID-19 forecasting tournament was wrong about these. What about you?
Aristotle argued that an enduring republic required a balance between democracy (popular participation and representation), oligarchy (expertise, serious stakes in the polity and elite gravitas) and monarchy (strong executive authority) if it was to avoid degeneration. It also required a reasonable degree of civic quality and economic equity among its citizens. If the balance was too much disturbed, crises would trigger regression to mob rule, tyranny or oppressive aristocracy. All this is at stake in America right now.
~Paul Monk, “It’s time to address the truth of President Trump”. Probably in The Australian.
From Pale Rider, Afterword:
…and novelists try to put themselves [in] the heads of those who lived through it…. Like worker bees they are busy weaving threads between the millions of discrete tragedies to create a collective memory - a living photograph of the Spanish flu.
I was reviewing this old interview with Australia’s Paul Monk, covering Coronavirus, China, conspiracy theories, reckoning, and risk to Pax Americana, as they looked to him in late April.
If nothing else, listen to him open by quoting Thucydides.
tl;dr Monk reviews key plagues from Athens to now, discusses the situation in April, and assesses three different China-did-it theories, and closes by arguing that the West must reckon with China, and it’s behavior during COV-2 has been a wake-up call.
I’ve had the pleasure to work briefly with Paul on argument mapping and critical thinking, and this is a good example of weighing plausibility and evidence.
It’s probably better to listen or read the interview, but here’s my summary of key points.
I’ve summarized Paul’s summary in a table, filling in numbers from Wikipedia or Ancient.edu (example). It seems the Roman plagues are hard to estimate because they lasted so long.
| Plague | When | Where | # Dead | % Pop |
|---|---|---|---|---|
| Athenian | 4th C BC | Athens | ~100K | ~1/4 - 1/3 |
| Antonine | 2nd C | Roman | ~5M | ~1/3 |
| Justinian | 5th C | Roman & Persian | ~25 - 50M | ~1/4 - 1/3 |
| Black | 14th C | Eurasia+ | ~75 - 200M | ~1/4 - 1/3 |
| Smallpox | 16th C | Americas | ~60M | ~95% |
| Great | 17th C | London | ~100K | ~1/4 |
| Spanish Flu | 20th C | Global | ~50-200M | ~2-3%, but young |
Monk does a nice job separating and assessing the China theories for the origin of SARS-COV-2. As of April, but it seems a solid assessment.
First, there’s the utterly mad theories: 5G and control chips. The China theories aren’t like that. That’s key.
Unrestricted War: deliberate leak. This gains plausibility from the 1997 book Unrestricted War by two Chinese colonels who suggested this possibility. So, it’s a viable theory - and important to note it was sensible for people to draw the connection. So, two avenues of assessment:
a. Sanity Check: Why would the Party agree, given grave risks? (a) How could they guarantee they could control it in China? (b) How could they be confident the outside world wouldn’t figure out whodunnit and “there would be hell to pay”? (c) To control in China you’d have to shut down the economy. Why? When you’re trying to dominate economically? Okay, so it would be hugely risky.
b. Evidence: None. [In the meantime we learned a bit more about how sus' they were acting, but Monk was pretty clear on that already. And their actions are pretty likely on the other China theories too. OK, what about biology? A Taiwanese dissident published a paper saying it was a deliberate release … but her claims for that fell apart. Her publishing circumstances were also dodgy. -And as I try to remind people, evidence is a ratio: to count for this theory, it has to be more likely on this theory than on its contenders. -ed]
c. Meta Evidence: some serious right-wing analysts looked at and dismissed this claim. You’d expect them to jump on it if they could. The intelligence communities in AU, NZ, CA, UK, and US all concluded this looks unlikely. Again, being their key job, you’d expect them to jump on it if they could - at least confidentially. But there’s no evidence in leaks or actions that this is considered remotely plausible.
Unintentional Escape A - It came from Wuhan or another lab, but the usual sort of leak. (Hi, I live in Reston. Ebola anyone?) In this variant, the party simply doesn’t know how it got out, takes awhile to figure it out, and when they do realize “Wow, this is serious”, they say so. If the Party had a history of acting responsibly, this might be more plausible. It doesn’t.
Unintentional Escape: B - As before, but once it leaks they think, “This looks bad” and conduct a propaganda campaign to suppress & whitewash. Evidence: they’re definitely conducting a propaganda campaign, including failed attempts to bully Australia and the rest of the WHO into not investigating.
Yes trading with China helped them prosper. Yes, that was good for us too. Yes, it’s middle class grew, and wanted more liberty. No, the Communist Party did not become more tractable. There was a glimmer of hope, and it was quashed.
Monk says it’s time to get consensus of Western & African countries, and tell China, “This cannot work. It can’t work for us and because it can’t work for us, you’re going to realize it cannot work for you. …there’s no other choice."
1918 and WWI led to the Great Depression, which ushered in reactionary politics around the world: Germany, Japan, Italy, El Salvador. We’re seeing signs now, and that threatens the Pax American that made possible “the greatest expansion in average human wellbeing across the planet … over the last [30-70] years ever in history.” To the extent that other countries follow China to say “Our interests are paramount … then we’re back in the 1930s.”
Paul thinks people have become more reflective, and the pandemic has highlighted the need for global solutions and clear thinking. I suspect it’s just Paul.
He has a nice analogy to The Martian though.
A touching, real conversation on faith, death, grief, culture wars, the Christmas season, comparative immigration, and briefly, Thatcher on climate. Underneath, kinship.
I’m not a fan of the XKCD “free speech” strip. I think it fails the reflexivity test. Lazy screenshot here.
On the other hand, Munroe usually does his homework. Is there a clearer discussion?

In a discussion with @Somensi about excess deaths, I was puzzled by an apparent discrepancy between two sources that have both been reliable, insofar as I can tell:
The basic question from mid-December was how to reconcile this and this:
![]() |
![]() |
With this:
(Screenshots are from mid-Dec.)
In short, by early December it was clear that covidtracking.com had started diverging wildly from the CDC excess death counts. Two basic theories:
There’s a lot of noise on the thread, but @Somensi, who I don’t know, was also looking at data, and citing a good source. Doomsters like me have been using CDC excess data since April as evidence that the pandemic was real and could not be simple relabeling of flu deaths. Here the same source is cited to say the December spike couldn’t be real.
People on both sides who knew the CDC data understood it had a lag of 4 weeks or so – because it relies on actual death certificates completing all their procedural checks and getting filed. In 2016 it took 10 weeks for 80% of certificates to get filed. CDC now claims it gets to 60% in ~10 days. (There are plenty of people who don’t get the lag – it seems even to have tripped up JHU’s Dr. Briand, at least in her headline claim that there were no excess deaths in 2020.)
Problem: covidtracking is the most thoroughly-vetted weekly data source in the US. They’ve tracked the CDC excess deaths (after lag) the rest of the year. And reliably, their cases –predict–> hospitalizations 4 weeks later –predict–> deaths a few weeks later. The December death spike followed that pattern. Plausibly, CDC was just lagging.
Problem: CDC 4 weeks back should be pretty good, and it looked nothing like April. As my correspondent said, CDC data “would have to be lagging by an unprecedented amount."
It’s obvious once you see it.
That death spike (swoop?) at the end is super fast. If you hover over the attributed deaths chart from covid-tracking, you find that the Nov. 14 cases are exactly in line with their July numbers, about half their April numbers. And in line with the mid-Nov. CDC numbers. The steep rise is mostly in the last 4 weeks.
As of Dec. 23, we can look at how the CDC data has changed. Data should be pretty complete through Nov. 21. We see that Nov. 14 is now about 1,000 higher than before (and than the July peak), and Nov. 21 about 2,000 higher than that.
Not a swoop yet, but basically on par with the covidtracking chart week-for-week. Here that is again from today, highlighting Nov. 21. (The bold line is the 7-day moving average, a far better comparison than the daily total.)
We should definitely expect the CDC excess deaths count for December to reach April levels.

“next to of course god america i

country ’tis of centuries come and go
and are no more. what of it we should worry
in every language even deafanddumb
thy sons acclaim your glorious name by gorry
by jingo by gee by gosh by gum
why talk of beauty what could be more beaut-
iful than these heroic happy dead
who rushed like lions to the roaring slaughter
they did not stop to think they died instead
then shall the voice of liberty be mute?”
He spoke. And drank rapidly a glass of water

HTT Tipsy Teetotaler via @ReaderJohn for reminding me of this gem.
Sounds like a fun blog, just shouldn’t be masquerading as a journal.
Instead of saying, “I’m a woman and I reject gender roles,” NB ideology says, in effect, “I reject gender roles and therefore I’m not a woman.”
Not my area of expertise, but a fascinating reflection. If sex is only psychological, then “woman" contracts to the 1950s stereotype, and “lesbian” is defined out of existence. Backfire.
Excellent discussion between Sullivan and Yglesias.
Had to grit my teeth through some of Yglesias’ verbal ticks early to mid, but good points throughout. Perhaps esp arguing the counter productive nature of not acknowledging progress on women’s/gay/black rights, or later the dangers of a cult of woke (taking for granted the dangers of the cult of trump).
Our July paper Are replication rates the same across academic fields? Community forecasts from the DARPA SCORE programme was briefly cited at the end of a recent unpublished manuscript by Tosh et al, including Gelman. We’re source 13:
5.3 Implications for social science research
As noted at the beginning of this article, there has been a crisis in psychology, economics, and other areas of social science, with prominent findings and apparently strong effects that do not appear in attempted replications by outside research groups (e.g., [24, 2, 13]).
Always happy for the shout out, but our paper [13] doesn’t do replications. It just shows what our forecasters generally expected in upcoming replications, and that before looking at the actual study candidates. About 60 of those replications have happened, but have to wait for the Center for Open Science to announce them. In the meantime, Anna Dreber Almenberg has reached out to Gelman’s team.
The unpublished “Gelman” manuscript is:
The piranha problem: Large effects swimming in a small pond by C Tosh, P Greengard, B Goodrich, A Gelman, D Hsu. Abstract:
In some scientific fields, it is common to have certain variables of interest that are of particular importance and for which there are many studies indicating a relationship with a different explanatory variable. In such cases, particularly those where no relationships are known among explanatory variables, it is worth asking under what conditions it is possible for all such claimed effects to exist simultaneously. This paper addresses this question with formal theorems that show, unless the explanatory variables also have sizable effects on each other, it is impossible to have many such large effects.
Phil Tetlock (and no doubt others) have noted informally that something like this must hold.
I look forward to reading this piece on my new Remarkable tablet.
