I’ve still been reading through Feyerabend’s Against Method, and following along what Rick and Bill have to say about his arguments, but it’s slow going. Sometimes slow is better than fast, especially these days.
Awhile ago Irfan Khawaja, a philosopher who has been purged from at least one libertarian inner circle and blacklisted from several others, sent me a bunch of journals: Critical Review, Raritan, and New Left Review. (I still owe him for the postage. Holla at me Dr K!) These have been veritable gold mines of insider knowledge, and I came across a 1990 article by James McCawley in Critical Review that aptly sums up my own raw thoughts on Feyerabend. Namely, the question of Feyerabend’s own brand of politics. Was Feyerabend unwilling to accept political anarchism even though he was a methodological anarchist?
I still don’t have a solid answer to this question, though the evidence so far points to an affirmative. If he wasn’t a political anarchist, what was he? Certainly not a Stalinist, but my guess is that his politics wouldn’t have been as original as his philosophy. I suspect he was, at heart, a democratic socialist along with most of his peers.
One of the more insider-y aspects of the McCawley piece was Ayn Rand’s dislike of Feyerabend’s methodological anarchism. McCawley points out that Rand read and responded to an early piece of Feyerabend’s, and that if Rand had been a little more tolerant, she and Feyerabend could have some stimulating (though no less heated) exchanges over the years. Alas.
I have a good eye for what ought to be there but isn’t. Don’t congratulate me; it’s a natural talent. I am retired so, I usually spend hours listening to the radio, reading newspapers and, watching television and, (Oops) on the internet. Nowadays, I do more of the same.
Today’s lecture is going to be a little longer than usual, on the one hand. On the other hand, there will not be a test. Bear with me; it’s going to be worth it (if I say so myself).
The first thing that’s missing from the endless and frankly a little sickening commentary on the C-virus epidemic is a good explanation of what’s a “model.” I mean the kind of models that are being blamed a little bit everywhere and especially in the conservative media for seemingly wildly inflated predictions (of infections, of deaths, of anything connected to this illness). Just from listening to talk radio, I think that some, or many, believe that with “computer models,” computers actually do the thinking instead of people. It’s not so.
The second thing missing is a clear description of the downside of national economic self-sufficency that appears so tempting now that we are extra-sensitive to both the comparative incompetence of our China-based suppliers, and to the possible ill-will of the Chinese Communist authorities.
First, first: a model is logically pretty much the same thing as we do when we say, ” On the one hand, on the other hand.” That’s as in, “One the on hand, If have saved $20, I will buy a nice cake; on the other hand, if I manage to save $200, I will look for a good used bike.”
The problems are: 1 that we have only so many hands; if we had one hundred each, and remembered each, we could produce mental models that cover more possibilities; 2 that we are not agile at combining possibilities, like this: “If the third hand and the fortieth hand are combined with the fifty-first then, this will happen.”
Models – designed by humans working slowly – can be entered into computers with many values and many combinations of values to tell us what would (WOULD) happen if… That’s all, folks.
Don’t blame the models, don’t blame those who build the models, in this capacity, rather, blame those who don’t do the needful to explain to decision-makers what actual models do and don’t do. (It’s true that they are often the same as those who actually construct the models but in a different role.)
Also, blame American universities and colleges that should have been in the business of teaching this stuff to all students since the late sixties and that have only done it for a tiny elite minority. A big missed opportunity. Even high school students could learn, I believe.
Second undiscussed issue. Under normal circumstances, self-sufficiency has a certain intuitive appeal: Let’s not count on others because they might fail, or fail us and, at any rate, distance makes the best linkages vulnerable. Now that we worry about running out of essential medical supplies made in China, now that we fear a shortage of the raw materials that go into our medical drugs, our intuition seems broadly vindicated. It did not help that a highly placed Chinese Communist official actually threatened the US aloud, about a month ago, with withholding medications. (I am guessing he is not going to have a happy retirement.)
Much about our intuition is correct, of course. As I never tire of stating (wittily, if you ask me), we should not count on steel deliveries from China to build the naval ships we would use in a war with China. The steel deliveries might be too late.
That’s on the one hand. On the other hand, there is a downside to national self-sufficiency. It violates the general principle that specialization makes for efficiency. Just imagine that you had to grow all your own grain, harvest it, mill it, raise your own cattle, slaughter it, butcher it, skin it, preserve the meat, treat the skins (and cut and sew clothes out of them). You would do a bad job of some of these tasks, at least, possibly of all. You would have much less to consume than is true now. You would be poor.
And that’s the downside: National self sufficiency is a sure path to poverty. I am not speaking of small differences but of big ones. I remember clearly when the cheapest hammer at the hardware store cost $20, five years later, the cheapest hammer cost only $5. What happened in between was expanded imports from China. (Don’t even begin to talk about quality; the difference among the cheapest items of a kind is largely illusory anyway, or much exaggerated.) And if you think this is a special case, ask your self if the Canadians – who love bananas – should grow their own in the name of self-sufficiency.* (For an expanded view of international trade, see my series of articulated short essays beginning here: “Protectionism; Free Trade, Step-by-Step.”)
Here again, American colleges and universities deserve strong blame. First, many don’t even require a course in economics to graduate. One of the best undergraduates I have known personally, an honors students who is now very successful in her career, never heard a single lecture on anything pertaining to economics. Second, economics professors, by and large, do a piss-poor job of teaching international trade. Across 25 years of teaching in a business school, I have met a fair number of good MBA students who had taken three courses in international trade and still did not see the possible downside of self-sufficiency. So, this simple idea is not widespread among the educated populace. It’s not well anchored enough in the opinion media for many to push back intelligently against the wave of demands that the US minimize its dependency on what we obtain from abroad in general. (A national policy designed to induce American companies to source in Vietnam, for example, rather than in China is a different and defensible proposition.)
So, here you have it: Models are not to blame, confusion about them is; economic self-sufficiency is the road to poverty though it might be worth it. Knowing these two things does not prevent us from taking action collectively. It makes for more rational action in these irrational times.
* Those of you who received a decent education in economics might wonder here if I have just dealt improperly with the topic of Comparative Advantage. I haven’t, I have not even begun.
There is a new UN Intergovernmental Panel on Climate Change report. It contains nothing but bad news, of course. But I am busy with my real life; I have obligations to others; I have to feed myself and shower; I even go to the gym regularly. What to do? Just trust a hysterical sixteen-year-old? (Yes, I mean Greta.)
When someone or something claims that there is, has been, change in something I perceive might be important, I apply the following four quick tests. I do this to decide how much I must attention I should pay to the change news.
1 Source credibility
Not all sources are created equal. Some stink, some have a long record of being reliable. The Wall Street Journal is one of the latter. Almost all anonymous internet sources are not even sources. The National Enquirer will publish anything (although it has had a few remarkable scoops). Normal sixteen-year old girls are only credible when they pronounce on show biz stars or on something related to a skill they have personally acquired, such as piano or gymnastics.
2 Main text: description of process
I scrutinize the description at the heart of the announcement of change though only for a short time. Does the process described make sense? Is it derived in an intelligible way from a study, or studies, that conform to conventional scientific, or other scholarly standards? If no claim is made that they do, they don’t, ever. If there is such a claim, there can still be abuse but there will shortly be a denunciation, in most cases, at least.
3 Narrative around description
Most change descriptions not directly in a scholarly journal come wrapped up inside a narrative. The narrative is often more interesting than the findings to which they are supposed to be linked. That’s intentional but dangerous. Suppose your doctor carefully measures your heartbeat and records his observations. Suppose that then, he gives you a very good lecture on the faults of Social Security. However valid the latter is, it should gain no authority whatsoever from the impeccable measurement of you heartbeat. This is a crude example but people do this sort of things all the time. Do you think climate activist do?
I ask myself how tightly connected the narrative is to the straightforward description of the relevant change? Often the answer is: barely, sometimes: not at all.
4 Gauging critically the order of magnitude of change
Suppose I tell you that I have lost weight. (I could use that.) Courtesy requires that you congratulate me but rationality demands that you ask: How much? If my response is one ounce, you will tend to dismiss my announcement and you will be right. One ounce out of 220 lbs is like nothing. (That’s aside from the fact that it might actually be nothing, a measurement error.)
The mysterious issue of “statistical significance” (that I will resist going into here though I am tempted) is only indirectly related to this matter. A difference between before and after, for example, may be statistically significant but yet, completely unimportant.
The short Wall Street Journal piece (1) covering the publication of the report is rich in narrative and short on figures. (That’s usually the case with climate change announcements, I think.) On rare figure drew my attention:
In the past 140 years -covering most but not quite all of the Industrial Age – global surface temperatures have risen by one (unit) degree Celsius.
To give you a practical idea, that’s not enough of a rise to cause me to take off my cotton sweater, or even to unbutton the top of my shirt. If the temperature rose by only one C between 8 am and noon, I would think something was wrong with the weather! I can easily believe that at this rate, in another 1400 years, it will be ten degree centigrade (Celsius) warmer and, we will still be here. That’s unless something else, something much more likely, like an epidemic. wipes us out. (2) and (3).
As this example illustrates, it may often be wise too reverse the critical sequence described above. Why bother to assess the source credibility associated with an announced change, or the conformity of the description change process to good scientific practice, or check out the attachment of the surrounding narratives to the process in the description, why do all this if the measured change is too small to merit attention?
My more complete ruminations on climate change skepticism are in Liberty Unbound: “Climate Change Denier.”
1 “U.N. Panel Sees Threat to Ocean” – by Robert Lee Hotz, Wall Street Journal 9/26/19, P. A8.
2 I am well aware that this is a sort of arithmetic average. Surface temperature may have gone up more in some areas and less in others. They may have declined in some places. If the subject is dealt with, it will be in: Watts Up with That.
3 The WSJ accounts implies that the UN report is oddly concerned with fisheries. This is odd because fishermen have known forever that there are warm and cool patches at the same latitude in the oceans. They also know that those shift positions and that the positions of such warm and cool patches affect the movements of fish.
A well-known Latin adage reads “de gustibus non est disputandum”, roughly translated as “about tastes it should not be disputed”. In English, we usually refer to the maxim as “over tastes there is no argument”, indicating the economist’s fundamental creed that tastes and preferences may very well come from somewhere but are useless to argue over. We can’t prove them. We can’t disavow them. Ultimately, they just are and we have to live with that.
In November last year, ridiculing a prominent Swedish politician, I used the example of ice-cream flavours to illustrate the point:
“I like ice-cream” is an innocent and unobjectionable opinion to have. Innocent because hey, who doesn’t like ice-cream, and unobjectionable because there is no way we can verify whether you actually like ice-cream. We can’t effortlessly observe the reactions in your brain from eating ice-cream or even criticize such a position.
Over tastes there is no dispute. You like what you like. We can theorize all we want over sociological or cultural impacts, or perhaps attempt to trace biological reasons that may explain why some people like what they like – but ultimately we must act in the world (Proposition #1) and so we shrug our shoulders and get on with life. We accept that people believe, like, and prefer different things and that’s that.
Being strange rationalising creatures, you don’t have to scratch humans very deeply before you encounter convictions or beliefs that make no sense whatsoever. Most of the time we’re talking plainly irrational or internally inconsistent beliefs, but, like most tastes and political opinions, they are very cheap to hold – you are generally not taxed or suffer noticeable disadvantages from holding erroneous or contradictory beliefs. Sometimes, by giving the speaker social kudos for believing it, the cost of holding an erroneous belief might even be negative – openly portraying it gives us benefits with our in-group. (yes, we’re all Caplanites now).
When I make a decision in the world (as I must to stay alive, Proposition #1), I occasionally feel the urge to explain that choice to others – because they ask or because I submit to the internalised pressure. I might say “eating ice-cream is good for me” (Proposition #2a).
Now, most people would probably consider that statement obviously incorrect (ice-cream is a sweet, a dessert; desserts make you fat and unhealthy, i.e. not good for you). The trouble is, of course, that I didn’t specify what I meant by “good for me”. It’s really unclear what that exactly means, since we don’t know what I have in mind and what I value as “good” (taste? Longevity? Complete vitamins? How it makes me feel? Social considerations?).
This version of Proposition 2a therefore essentially reverts back to a Proposition 1 claim; you can like whatever you want and you happen to like what ice-cream does to you in that dimension (taste, feeling, social consideration). Anything still goes.
I might also offer a slightly different version (Proposition #2b) where I say “eating ice-cream is good for me because it cures cancer”.
Aha! Now I’ve not only given you a clear metric of what I mean by ‘good’ (curing cancer), I’ve also established a causal mechanism about the world: ice-cream cures cancer.
By now, we’ve completely left the domain of “everything goes” and “over tastes there is no argument”. I’m making a statement about the world, and this statement is ludicrous. Admittedly, there might be some revolutionary science that shows the beneficial impacts of ice-cream on cancer, but I seriously doubt it – let’s say the causal claim here is as incorrect and refuted as a claim can possibly be.
Am I still justified in staying with my conviction and eating ice-cream? No, of course not! I gave a measure of what I meant by ‘good’ and clear causal criteria (“cure cancer”) for how ice-cream fits into that – and it’s completely wrong! I must change my beliefs, accordingly – I am no longer free to merely believe whatever I want.
If I don’t change my behaviour and maintain enjoying my delicious chocolate-flavoured ice-cream, two things happen: First, I can surrender my outrageous claim and revert back to Proposition 1. That’s fine. Or I can amend Proposition 2b into something more believable – like “eating ice-cream makes me happy, and I like being happy”.
What’s the story here?
If we substitute ice-cream for – I posit with zero evidence – the vast majority of people’s beliefs (about causality in the world, about health and nutrition, about politics, about economics and religion), we’re in essentially the same position. All those convictions, ranging from what food is good for you, to how that spiritual omnipotent power you revere helps your life, to what the government should do with taxes or regulations to reduce poverty, are most likely completely wrong.
Sharing my own experiences or telling stories about how I solved some problem is how we socially interact as humans – that’s fine and wonderful, and essentially amounts to Proposition 1-style statements. If you and I are sufficiently alike, you might benefit from those experiences.
Making statements about the world, however, particularly causal relations about the world, subjects me to a much higher level of proof. Now my experiences or beliefs or tastes are not enough. Indeed, it doesn’t even matter if I invoke the subjective and anecdotal stories of a few friends or this or that family member. I’m still doing sh*t science, making claims about the world on seriously fragile grounds. It’s not quite Frankfurt’s “Bullshit” yet, since we haven’t presumed that I don’t care about the truth, but as a statement of the world, what I’m saying is at least garbage.
I am entitled to my own beliefs and tastes and political “opinions“, whatever that means. I am not, however, entitled to my own facts and my own causal mechanisms of the world.
Keeping these spheres separate – or at least being clear about moving from one to the other – ought to rank among the highest virtues of peaceful human co-existence. We should be more humble and realise that on most topics, most of the time, we really don’t know. But that doesn’t mean anything goes.
