Planning for pandemics (repost from 2005)

The news of deaths from bird flu in Indonesia is pretty scary. Although, as I’ve mentioned recently Indonesia has made a lot of progress in many respects, the handling of this threat so far seems to show the worst of both worlds: all the ill ffects of authoritian habits combined with the timidity of weak politicians. There have been a lot of coverups, and an unwillingness to tackle the necessary but unpopular task of slaughtering affected flocks of birds. Things seem to be improving now, but there’s a long way to go.

It seems very likely that, sooner or later, bird flu will make the jump that permits human-human transmission, and quite likely that a major flu pandemic will result. The world, including Australia, is very poorly prepared for this. One thing we could do to prepare is to adopt a national program encouraging annual flu vaccinations for everyone, instead of just for limited categories of vulnerable people.

The main benefit of this is not that the shots would provide immunity against a new and deadlier flu variant (though there might be some limited benefit of this kind) but that we would have the infrastructure, production facilities and so on to undertake a mass vaccination against such a variant if it arose. As it is, it seems likely that many countries will be scrambling to get access to an inadequate world supply of vaccines, but if Australia and other developed countries ramped up normal levels of production, it would be much easier to generate extra supplies for our neighbours.

I haven’t looked into it, but my guess is that, even without considering the possibility of a pandemic, the benefit-cost ratio from such a measure would be pretty high. Flu is very costly in economic terms, and I suspect that, if pain and suffering were thrown into the balance, a program of universal free vaccination would come out looking pretty good.

Notes  I wrote this in 2005 thinking about new flu strains. The only difference I see with “novel” viruses is that the time taken to produce the initial batches of a vaccine is likely to be longer. As is usual with my policy advocacy, little if anything has been done along the lines I suggested.

The statistical significance of focus groups

I’ve generally taken a pretty dim view of focus groups, which seem to be used mostly to detect and amplify unthinking prejudices. But, I have to admit, that probably is due at least in part to the fact that my prejudices aren’t very close to those of the median focus group participant. So, it wasn’t until I saw focus group results matching my own thoughts that I paid any attention to the question of whether the results actually meant anything.

According to the SMH report, participants in two Ipsos focus groups almost uniformly saw Morrison’s response to the bushfires as “pathetic” and “lacking empathy”. In each case, eight of nine respondents gave such negative views. Ipsos also concluded there was “little confidence” Labor leader Anthony Albanese would have provided better leadership, with descriptions like “weak” and “bland” being offered. Regular readers won’t be surprised to learn that I agree with both judgements.

But how much can we learn from an exercise involving only eighteen participants? Surprisingly, the answer is, quite a lot. Use q to denote the proportion of the population who approve of Morrison

If the population from which the group was drawn was evenly divided between approvers and disapprovers, the chance of getting results like this would be tiny. This table (look at N=18, x = 16, p 0.5) gives it at 0.000584. A classical hypothesis test would reject the null hypothesis (or, in the usual jargon, find a statistically significant effect) for any chance below 0.05. Using a more sensible, Bayesian approach, with just about any prior distribution, the updated estimate of for the distribution of q would lie entirely below 0.25 (25 per cent approval). We could do something similar for Albanese, but the exact numbers aren’t given.

These numbers are substantially worse than the approval/disapproval numbers given by Newspoll. So what is going on?

Australia Day

There have been Australia Days more loaded with fear and foreboding than yesterday’s (in 1942, for example), but not many. Richard Flanagan’s jeremiad in the New York Times might be overstated, but it’s a lot closer to the mark than our appalling Prime Minister’s suggestion that we should take the time to celebrate our greatness as a nation.

Nuclear update: Gen III dies an early death

One of the more tenacious beliefs on the political right is that their support for nuclear power demonstrates superior rationality and openness to evidence. But the evidence is that, no matter what the structure of energy markets no one is willing to choose (new) nuclear power over any of the alternatives: gas, renewables and coal. That’s bad in the sense that the true costs of new and existing coal far exceed those of even new nuclear. But where those costs are factored in to decisions, it’s renewables (plus storage) that benefit.

Let’s look at the evidence. The World Nuclear Association currently lists “about 50” plants under construction, a number that’s been declining over time. A closer look reveals 47 plants, of which 23 are due to be completed this year or next (most are way behind schedule). The rest are due by 2026 reflecting the fact that hardly any have been started in recent years (a typical project takes 7-10 from initial construction to connection, if all goes well).

Adding in those modern (Gen III or III+) plants already in operation, the total contribution of modern nuclear to the world’s electricity generation capacity is likely to fall short of 100 GW, maybe equal to a couple of years of renewables (adjusted for differences in utilisation rates).

The only real hope is that of Small Modular Reactors, but even here the gap between claims and evidence is striking. Pro-nuclear advocates routinely write as if SMRs are an established solution, rather than a design that has so far not even reached the pilot plant stage.

If those on the political right would accept a market solution to decarbonizing electricity, including a carbon price and an option for SMRs, that would be a good deal for the environment. Sadly, there’s no sign of that happening. Rather, support for nuclear power is little more than an excuse for hippie-punching and intellectual self-congratulation.

Climate change and the strange death of libertarianism

It wasn’t that long ago that everyone was talking about the “libertarian moment” in the US. Now, libertarianism/propertarianism is pretty much dead. The support base, advocacy groups and so on have gone full Trumpists, while the intellectual energy has shifted to “liberaltarianism” or, a more recent variant, Tyler Cowen’s conversion to “state capacity libertarianism“.

Most of those departing to the left have mentioned the failure of libertarianism to handle climate change. It was critical for two reasons. First, any serious propertarian response would have required support ofr the creation of new property rights (emissions permits) and the restriction of existing ones (burning carbon). That would imply an acknowledgement that property rights are not natural relations between people (owners) and things (property). They are socially constructed relationships between people, allowing some people to use things and to stop other people from doing so. Second, the effort to deny the necessary implications of climate change inevitably resulted in denial of the scientific evidence that climate change was occurring. That contributed to a situation where most former libertarians are now Trumpists, happy to deny the evidence of their own eyes if that’s what the leader requires of them.

I’m working on a longer article spelling all this out. In the meantime, comments welcome.

Consumed by fire (crosspost from Crooked Timber)

(Most of this will be familiar to regular readers of this blog. But it seems simplest to crosspost the whole thing, rather than do a separate version).

It’s been hard to think straight with the fires that have burned through most of Australia for months. Brisbane was among the first places affected, with the loss of the historic Binna Burra lodge, on the edge of a rainforest, a place where no one expected a catastrophic fire. But, as it turned out, we got off easy compared to the rest of the country. Heavy rain in early December helped to put out the fires in Queensland, and we can expect the delayed arrival of the monsoon in the near future. By contrast, southern Australia normally has hot, dry summers and this has been the hottest driest year ever. The increased likelihood of catastrophic fire seasons was evident when I started work on this topic back in 2012 [1], and the risks for this year were pointed out to the government months in advance. The warnings went unheeded for two reasons.

First, the government had been re-elected partly on the basis of a promise (economically nonsensical, but politically powerful) to return the budget to surplus. Any serious action to prepare for and respond to a bushfire catastrophe would wipe that out, as indeed has almost certainly happened now.

Second, any serious assessment would have to focus on the fact that climate change is causing large-scale losses in Australia right now. The government is a combination of denialists and do-nothingists, neither of whom are willing to address the issue.

Of course, Australia is only a small part of the problem. Our government’s policies are helping to promote climate catastrophes in the US, Brazil and other places, and theirs are returning the favor. A policy shift in any one of these countries, with no change elsewhere, would make little difference to the country concerned. That’s the nature of a collective action problem. But on any ordinary understanding of justice, we are reaping what we, and the governments we’ve elected, have sown.

Over the fold, some links to pieces I’ve written on this topic.

Climate deniers are worse than antivaxers but get treated better, from my blog

Burning the surplus, from my blog

Mainstream media remains quiet on Scott Morrison’s untimely holiday from Independent Australia. As the worst of the disaster started to unfold, our appalling Prime Minister skived off to Hawaii for a luxury holiday, without telling anyone. Most of the media were happy to cover for him.

fn1. Instant social media reactions have their problems, but the academic alternative, endless rounds of refereeing, is far worse. I started work on this topic with a colleague Tyron Venn, in 2012, but it didn’t get past the referees until 2017, by which time the central point (the case for mandatory evacuation, rather than encouraging people to defend their homes against fire) was generally accepted. And the demand for a tight focus meant that the discussion of climate change, my original motivation for doing the project, was cut down to a single sentence. For anyone interested, here’s a link.

Old men behaving badly (3rd repost)

I first posted this in 2011, reposted it in 2014 and again in 2019. Sadly, nothing changes, except that the old men keep getting stupider and behaving worse.

John Howard’s endorsement of Ian Plimer’s children’s version of his absurd anti-science tract Heaven and Earth has at least one good feature. I can now cut the number of prominent Australian conservatives for whom I have any intellectual respect down from two to one.[1] Howard’s acceptance of anti-science nonsense shows that, for all his ability as a politician, he is, in the end, just another tribalist incapable of thinking for himself. [2]

Although not all the tribal leaders are old men, an old, high-status man like Howard is certainly emblematic of Australian delusionism . Like a lot of old, high status men, he stopped thinking decades ago, but is even more confident of being right now than when he had to confront his prejudices with reality from time time. Like other delusionists, Howard has no scientific training, shows no sign of understanding statistics and almost certainly hasn’t read any real scientific literature, but nonetheless believes he can rank clowns like Plimer and Monckton ahead of the real scientists.

The situation in the US is similar but even more grimly amusing, with the sole truthteller in the entire Republican party, Jon Huntsman, recently reduced to waffling (in both US and UK/Oz senses of this term) because he briefly looked like having a chance to be the next non-Romney. This tribal mindlessness is reflected in the inability of the Republican Party, at a time when they ought to be unbackable favorites in 2012, to come up with a candidate who can convince the base s/he is one of them, but who doesn’t rapidly reveal themselves as a fool, a knave or both.

And, as evidence of the utter intellectual shamelessness of delusionism, you can’t beat the campaign against wind power, driven by the kinds of absurd claims of risk that would be mocked, mercilessly and deservedly, if they came from the mainstream environmental movement.

The global left is in pretty bad shape in lots of ways. Still, I would really hate to be a conservative right now.

fn1. Now (2014) down to zero. Turnbull has proved he lacks any real substance.

fn2. I’m not saying that all Australian conservatives are mindless tribalists. There’s a large group, epitomized by Greg Hunt and now Malcolm Turnbull, who understand the issues quite well, but are unwilling to speak up. Then there is a group of postmodern conservatives of whom Andrew Bolt is probably the best example, who have passed the point where concepts of truth or falsehood have any meaning – truth is whatever suits the cause on any given day.
