For a stat head like me, it’s becoming increasing painful to follow the media. There’s an absolute orgy of misinformation, innumeracy and wild conspiracy theories, pouring forth in increasing volume.
One of the best examples is the claim that there are a vast number of hidden coronavirus cases. One argument is that many cases are asymptomatic. That’s true, but we have a pretty good idea as to how many asymptomatic cases exist, and its not enough to materially change the picture. It seems like somewhere in the ballpark of 50% of cases are asymptomatic. Don’t be innumerate, there can’t be that many undetected cases. Testing would have picked it up. Half the UK population did not catch the disease. If it did, right now it would look far worse than Lombardy or Wuhan.
Now it’s reported that the UK government believes that China has vastly underreported the number of actual cases:
Boris Johnson’s government is reportedly furious with China’s handling of the coronavirus, with UK officials quoted on Sunday warning that Beijing faces a “reckoning” once the COVID-19 crisis is over.
UK government officials believe China is spreading disinformation about the severity of the coronavirus outbreak in its country, the Mail on Sunday reports.
The newspaper says scientists have warned Johnson that China could have downplayed its number of confirmed cases of the coronavirus “by a factor of 15 to 40 times.” China had reported just 81,439 at the time of writing.
Similar claims are being made about Japan, and other countries.
Here’s the problem with these wild conspiracy theories. Everyone knows that the reported caseload totals are below the actual totals, because many people with coronavirus never get tested. But that’s true almost everywhere. Globally, there are 33,500 deaths and 700,000 cases. Most evidence points to a mortality rate of roughly 1%, suggesting there are actually at least 3.3 million cases. And even that’s a low estimate, as lots of people currently infected will eventually die.
China probably has less underreporting that average, as their caseload peaked much earlier and most of the deaths that will eventually occur have already occurred. And yet despite that fact, even reported death rates in China are currently lower than the world average. Adjusting for demographics, they are probably roughly equal. Japan has very few deaths, so the caseload can’t be that wildly inaccurate.
We’re told that Boris Johnson is “furious” with China for its lies and misinformation. I’m also furious with China for its lies and misinformation. I’m also furious with the US government for all its lies and misinformation. I’m furious that as Americans were preparing to attend Mardi Gras, Trump was telling them that everything was under control. I’m furious with the UK government for wasting time on a “herd immunity” strategy before backtracking. I’m furious that Boris Johnson is relying on experts who are innumerate. I’m furious that my fellow white people have screwed up this epidemic 100 times worse that Asian people. Look at the list of the top 20 countries, in terms of active cases (right column). At least 18 are white countries, 19 if you include Brazil as white. And the 20th (Korea) will fall entirely off the list by the middle of this week. And this was an Asian problem as recently as mid-February. We had plenty of time to prepare, and twiddled our thumbs.
A global epidemic? Bull****, it’s a white man’s disease. But that won’t stop white people from looking for scapegoats. We’re no more advanced that the medieval peasants who blamed diseases on Jews and witches.
I expect some commenters to tell me the China data is fake, and that the disease is running rampant in China. In fact, it would be shocking if the Chinese did not have the disease under control. They adopted far more draconian social distancing tactics than did the rest of East Asia, and in most of the rest of East Asia the level of community transmission is also quite low. (Japan may be picking up, and some others are seeing a recent surge of imported cases—as is China.)
Believe it or not, it’s possible to have a general idea of what’s going on in China without relying on the Chinese media, which is full of propaganda. We know that they have draconian social distancing. We know that there is no surge in coronavirus deaths occurring all over China (as of today, it may occur later), and we know the hospitals are not currently being overrun with coronavirus patients. There are likely several million phone calls a day between Chinese people outside China and those within, including medical personnel within China. It’s not a black box.
The key to interpreting the news is:
1. Don’t be innumerate.
2. Understand what sort of things governments lie about, and what sort of things they don’t lie about, because they fear being discredited. The lies undertaken by the Wuhan government were incredibly costly to the central government of China. The Chinese public was furious, the truth got out anyway, and it delayed by a week or two the national lockdown and quarantine of Hubei. It was a PR and health care disaster for China. So why did the Wuhan government lie? They probably thought the epidemic would blow over quickly and they’d get away with it. (This article provided a narrative of how the lies played out.)
Governments lie when there is little cost. Thus there’s not much cost to the Chinese government in claiming the camps for Muslims in Xinjiang are re-education camps. The costs would be somewhat higher if they insisted no such camps exist. A top Chinese official recently claimed the virus was created in a US lab. Then another top Chinese official said that’s “crazy” (as it is). That’s an example of an issue where the Chinese government itself probably had a change of mind on the value of the lie, due to a backlash.
Trump is quite similar. He lies frequently in his twitter feed, but tries to avoid the sort of obvious lies that his supporters would immediately spot, and be embarrassed by. (Instead, he does the sort of lies that I easily spot.)
Unless you understand how and why governments lie, you’ll never be able to interpret data properly.
PS. Tyler Cowen recently linked to a bunch of claims about the coronavirus data, many of which are unpersuasive. Iceland is treated as an outlier because it has a low death rate. But death rates across countries are quite uneven; just a few weeks ago Germany had a similar low death rate, and since then it’s edged upward. It’s likely that some of the Icelanders now infected will eventually die. Another link suggests as many as 40,000 deaths in Wuhan, which seems highly implausible. That’s more than the entire world has today. Ah, but you say, “It started earlier in Wuhan.” True, but it also ended much earlier in Wuhan. It started in late 2019, but even in early January it was just picking up momentum. By January 23 you had the hard lockdown that stopped it in its tracks. Not enough time to produce a caseload that would lead to 40,000 deaths. If it were, we’d be seeing 40,000 deaths in many other cities. But we aren’t.
PPS. LOL at the innumerate Alabama governor who said “we’re not California”. Yeah, you’re worse.
PPPS. Wuhan is now building a lovely riverfront park. Wuhan is not a symbol; it’s an actual place with 11 million people, all getting on with their lives. We should be trying to cooperate more with China, not less. Stop saying China is evil, and start saying Xi Jinping is evil.
