It ranks pretty high.
> Like Ezra Klein, whom he admires, Nate Silver had made a success out of an escape into diffidence. What is it about conviction that frightens these people?
It's not conviction that's frightening, it's conviction backed by ignorance.
It's hard to read that in a friendly manner, it sounds like it would be so awful to have people thinking for themselves.
I think it is maybe a little optimistic, but an 'open society' probably works better the closer you get to discarding the idea that some people are intellectuals.
(I don't mean that as a rejection of expertise, but someone with a deep understanding of the dynamics of region (or whatever) is really only better positioned to explain the probable consequences of an action, their expertise doesn't really give them more standing to choose what action is best)

More data can also mean more noise. More data can also mean implying more causation where none exists. And the world isn't a giant game with sterile constraints and static rules.
> More data can also mean more noise.
Nate Silver wrote a book titled "The Signal and the Noise." I'm sure he's aware of the danger. Data Analysis (Data Science, whatever you want to call it) is all about turning data into information. Reducing noise.
What’s more dangerous, the bias in an opinion page or bias in a feature article masquerading as neutral fact?
More data, more samples, can produce more spurious relationships, whatever statistical massaging is applied. Given more Noise, there’s more opportunity to inject bias in finding your Signal. Journalists shouldn’t pretend their data doesn’t stink because they just figured out how to get Excel to crap out regression results.
Oh yeah, backed by not owning up to their convictions when someone without all their deficiencies proves them wrong with fact (or at least strong evidence).
Towards the end of the article, the author asks "Is numeracy really what American public discourse most urgently lacks?" I cannot believe there is a red blooded American who could sincerely ask this question. Americans are paranoid that our schools are falling behind the Russians, the Danes, or the Chinese. Education is part of the American dream. The knowledge and understanding people have of the issues of the day is a metric for the strength of a democracy.
The author leaves us with a final question: "What is it about conviction that frightens these people?" upon which he refuses to speculate. Although he is the literary editor of the New Republic, he does not recognize that the fox essay is in the genre of manifesto (I wouldn't have known it either, but it was written in at the top).
Manifestos are meant to be self-aggrandizing and they will always define their subject over and against what already exists. Mr. Wieseltier needn't worry about the op ed page, it will survive Data Journalism.
Silver isn't doing LHC observations here: he's doing political journalism, and data in politics and economics are neither neutral nor objective. The data we select, the models we use, create toy realities that we can use to justify certain policies and philosophies.
What makes Silver particularly pernicious -- and I count myself a fan of his approach to weighting election polls -- is that he pretends that data and modeling means 538's articles are endowed with an Olympian objectivity. Yet his hires suggest that his articles are going to be animated more by ideology than rigor.
For example, he chose for his science writer Roger Pielke Jr., a political scientist whose climate-change denialism (usually published as popular books, op-eds, and blog posts, not peer-reviewed papers) has been thoroughly debunked by practicing scientists. Not a promising beginning to his site; if I wanted to read worthless contrarianism written by unqualified hacks, I'd just renew my New Republic subscription.
This writer makes some good points, but I don't think Silver is attempting to use statistical analysis to answer these questions. Silver's point about opinion journalism is one about bad incentives-- those people are rewarded for attracting attention, not for being accurate or even thoughtful. He's attacking the George Wills of the world for saying things like "Romney will win because Americans have realized that blah blah blah" when all the available polling data indicated a landslide win for Obama.
Of course there is room for opinions and certainly an appetite for it, but the problem for the New Republic is that the authority bestowed upon "publications" is rapidly eroding. This obviously hasn't been helped by their decisions to compete with the Buzzfeeds of the world in the race to the bottom for pageviews. Now that anyone can say anything in public, the fact that the New Republic has decided to employ you no longer makes your opinion automatically worthy of consideration.
So what is Leon Wieseltier saying here about Nate Silver, exactly? That Silver considers himself to have no priors? That he, Wieseltier, thinks that Silver has no priors? Both interpretations seem ignorant. Further, how can someone "know many things" and yet have no priors, when a prior is a representation of prior knowledge?
I find it hard to believe that Wieseltier would be so dumb by accident, which means it's actually on purpose. The article is an attack on the sort of public discourse Silver wants - arguing over likelihood of outcomes under uncertainty - in favour of "repetition" and "persuasion". Are those "what American public discourse most urgently lacks?"
