Trump’s Knowledge

23 Comments

George Will says he doesn’t even know what knowledge is:

As president-elect, Trump did not know the pedigree and importance of the “one China” policy. About such things he can be, if he is willing to be, tutored. It is, however, too late to rectify this defect: He lacks what T. S. Eliot called a sense “not only of the pastness of the past, but of its presence.” His fathomless lack of interest in America’s path to the present and his limitless gullibility leave him susceptible to being blown about by gusts of factoids that cling like lint to a disorderly mind.

The problem is that he thinks he has “a very good brain.” This is Dunning-Krugerish.

But I’m still relieved that she lost.

That Time Of Year Again

It’s Victims Of Communism Day, 2017:

This year is a particularly important time to remember the victims of Communism because of the approaching one hundredth anniversary of the October Revolution – Bolshevik takeover of Russia. The Soviet Union was not the most oppressive communist regime. It probably did not match the even more thoroughgoing totalitarianism of the Khmer Rouge and North Korea. Nor did it kill the most people – a record held by Mao Zedong the Chinese communists. But the Soviet experiment was the principal model for all the later communist states, and it is hard to imagine communists seizing control of so much of the world without it. In addition to the significant material aid that the Soviets provided to communists in other nations, the communist seizure of power in Russia also greatly boosted the ideology’s prospects elsewhere.

My neighbor of a few blocks away is whining about his victimhood:

I am also victimized for my unpaganhood, and I am constantly pressured to conform and accept weird weather religions and the theological musings of internet hipsters who think the idea of Christian grace is some sort of supernatural point system where you get into heaven for accomplishing a set number of good deeds. I reject these attempts to subjugate me to the dominant discourse, just as I reject the liberal Jesusplaining that seeks to steal my savior and turn him into some sort of socialist hippie, a Bernie Sanders in a robe who thinks the only sin is generating too big of a carbon footprint.

And then there is the systemic hate for my rigidly male monosexual identification and my pronounced pro-chick agenda. Too often those of you who are genderfluid deny the identity of those of us who are gendersolid.

Same.

Mindless Eating

…and mindless research:

Problems with p-hacking are by no means exclusive to Wansink. Many scientists receive only cursory training in statistics, and even that training is sometimes dubious. This is disconcerting, because statistics provide the backbone of pretty much any research looking at humans, as well as a lot of research that doesn’t. If a researcher is trying to tell whether changing something (like the story someone reads in a psychology experiment, or the drug someone takes in a pharmaceutical trial) causes different outcomes, they need statistics. If they want to detect a difference between groups, they need statistics. And if they want to tease out whether one thing could cause another, they need statistics.

The replication crisis in psychology has been drawing attention to this and other problems in the field. But problems with statistics extends far beyond just psychology, and the conversation about open science hasn’t reached everyone yet. Nicholas Brown, one of the researchers scrutinizing Wansink’s research output, told Ars that “people who work in fields that are kind of on the periphery of social psychology, like sports psychology, business studies, consumer psychology… have told me that most of their colleagues aren’t even aware there’s a problem yet.”

I think the hockey stick episode shows that this is a problem with climate research as well.

The point of peer review has always been for fellow scientists to judge whether a paper is of reasonable quality; reviewers aren’t expected to perform an independent analysis of the data.

“Historically, we have not asked peer reviewers to check the statistics,” Brown says. “Perhaps if they were [expected to], they’d be asking for the data set more often.” In fact, without open data—something that’s historically been hit-or-miss—it would be impossible for peer reviewers to validate any numbers.

Peer review is often taken to be a seal of approval on research, but it’s actually more like a small or large quality boost, depending on the reviewers and scientific journal in question. “In general, it still has a good influence on the quality of the literature,” van der Zee said to Ars. But “it’s a wildly human process, and it is extremely capricious,” Heathers points out.

There’s also the question of what’s actually feasible for people. Peer review is unpaid work, Kirschner emphasizes, usually done by researchers on top of their existing heavy workloads, often outside of work hours. That often makes devoting the time and effort needed to catch dodgy statistics impossible. But Heathers and van der Zee both point to a possible generational difference: with better tools and a new wave of scientists who aren’t being asked to change long-held habits, better peer reviews could conceivably start to emerge. Although if change is going to happen, it’s going to be slow; as Heathers points out, “academia can be glacial.”

“Peer review” is worse than useless at this point, I think. And it’s often wielded as a cudgel against dissidents of the climate religion.
