Two kinds of ignorance

John Quiggin99 Comments

Also, in yesterday’s Fin, Geoffrey Barker accused Abbott of going for the bogan vote (paywalled), where bogan is taken to mean ignorant. Leaving aside the class/cultural analysis implicit in the term “bogan”, which I think is wrong, the argument is the same as I made in my post on agnotology, as his characterization of Rudd as a technocrat, not really at ease with the kind of politics that includes demands for authenticity and so on. Coming back to “bogan”, the big issue in agnotology is not ignorance in the ordinary sense of the term (people who don’t know much about political issues, and don’t care to learn – that is certainly part of the stereotypical bogan image, and may perhaps be descriptive of the actual demographic groups commonly associated with the term, though I don’t know of any evidence of this).

The ignorance associated with climate change delusionism and other rightwing factoids is metacognitive and has much more to do with the Dunning-Kruger effect of overestimating one’s own competence. The classic example is the kind of person who eagerly circulates reports that there has been no statistically significant warming since 1995. The only information content in such a report is that the person doing the reporting doesn’t understand the concept of statistical significance[1], and therefore is incapable of assessing any issue involving statistical analysis, of which climate change is a prime example.

The stereotypical candidate, in relation to climate change, is that of a 50+ male[2] with a business background in engineering or some similar field where practical judgement is accorded more value than theoretical expertise, and where a willingness to push on regardless is an important element of success. Journalists and opinion columnists[3], accustomed to “mastering a brief” at short notice are also highly susceptible – lawyers who may actually have to master briefs involving technical issues seem mostly to recognise that this is the kind of problem where expert judgement is required, as does the more sensible kind of economist[4]

fn1. Note for pedants. A Bayesian statistician would say that confusion over the concept of significance reflects the logical problems of the concept and the underlying classical theory of statistics. But that only makes sloppy misuse of the concept even worse. I’ll have more to say on this soon, I hope.

fn2. A demographic group to which I belong

fn3. This one, too.

fn4. This one, too, I hope.

Haiti disaster

John Quiggin27 Comments

The Haiti earthquake looks to be one of the worst natural disasters in recent years. Lots of aid agencies will be involved in rescue and recovery efforts, but I’ll mention PLAN International which has been active in Haiti for a long time.

Remember also that, while earthquakes and tsunamis rivet our attention, hunger and disease are cutting lives short every day. Give what you can, whenever you can, to help.

Text and writing

John Quiggin29 Comments

Tigtog at LP points to a study showing that involvement with Facebook, MSN and so on has increased the textual skills of young people, including not just “good writing” but the ability to adapt style to an imagined readership that varies in different context. I was banging on about this last millennium.

Tigtog finishes with a really last-millennium question? “Does anybody here still do lots of handwriting?”.

For those who don’t recall, “handwriting” was a method of producing text, popular in the second millennium, in which, rather than using a keyboard or pointer to produce letters, you used an ink-dispenser to draw each letter in succession. There was a version of this called “cursive” or “script” in which, rather than drawing the letters separately, they were all run together. This was much faster to produce, but, as I recall, almost impossible to read unless done by a real expert. I can still do a very inexpert version of the letter-by-letter method, which was called “printing” (nothing to do with real printing, but the result, done well, looked a bit like printed text).

Saving the cat

John Quiggin15 Comments

Quite a while ago, I raised a question about the practical implications of the “rapture” doctrine, held by large numbers of evangelicals.

Do they install automatic watering systems for their gardens and arrange for unsaved neighbours to feed the cat? Or do they just pay into their IRAs as if they expect the world to last forever?

Now it appears, some enterprising atheists have set up a service addressing one of the problems I raised. In the event of rapture, they guarantee that , assured of being left behind, they will look after the pets of those who are taken up. (video here)

Generations change, but the game remains the same

John Quiggin89 Comments

I tried to ignore it, but Employment Services Minister Mark Arbib’s resurrection of the (Tony Abbott?) “job snobs” line has turned into yet another tiresome round of the generation game. This time it’s Generation Y who are copping the flak for being “Generation Lazy”, a collection of job-hoppers and dole bludgers.

How many times must these cannonballs fly? Arbib (born 1971) was barely out of nappies when the phrase “dole bludgers” was coined and applied to the unemployed members of Generation Jones (the younger boomers who missed out on the fun of the 60s), a group to which I briefly belonged. That continued right through the late 1970s, and into the recession of the early 1980s. And even before that, the older boomers had been routinely labelled as work-shy hippies.

The recession of the 1990s hit all groups of the population, with older workers suffering even more than youth. Still, the old cliches were dragged out and applied to Gen X-ers (remember the Paxtons?)

Now the economy has soured again, and Gen X bosses and pollies are kicking their Gen Y subordinates. If the slowdown drags on as long as I expect, it will be the turn of Gen Z/Millennial/Potter before long.

As I said back in 2000

Much of what passes for discussion about the merits or otherwise of particular generations is little more than a repetition of unchanging formulas about different age groups Ð the moral degeneration of the young, the rigidity and hypocrisy of the old, and so on.

You couldn’t get a better example than the latest round of recycled cliches.

Coincidences

John Quiggin10 Comments

I gave two talks yesterday, one in Wollongong and one in Parramatta, about different aspects of the financial crisis. In both cases, my initial destination was the corner of Church and Market Streets and the person who had organised my trip was taken ill and couldn’t attend the talk. By this morning, I was a bit confused as to my location and status.

Declining Biblical knowledge

John Quiggin76 Comments

I was willing to believe a headline stating that Biblical knowledge is in decline, but after looking at the story, I think the decline must be located somewhere else. It starts off by observing that

Forty per cent did not know that the tradition of exchanging Christmas presents originated from the story of the Wise Men bringing gifts for the infant Jesus

I’ll confess to being among the 40 per cent before I read the story, and remaining among them afterwards. Let’s leave aside the observations that the custom of midwinter giftgiving almost certainly predates Christianity, and has nothing to do with Christianity in the religious sense of the term. Even in the fictional universe of what might be called folk Christianity I didn’t (and don’t) believe that this claim is canonical. There seem to be all sorts of stories to account for Chrissy presents – the one I would have offered unprompted relates to Saint Nicholas, a prototypical Father Christmas figure.

Then there’s the observation that only one in 20 can name all ten commandments. Maybe I’m wrong, but I suspect if you popped this question up to a bench of bishops with no notice, and required the commandments to be given promptly and in order, you’d get a fair few failures, though maybe not as amusing as this one
