David Brooks discovers Red State Blue State Rich State Poor State!

The New York Times columnist writes: Our political conflict is primarily a rich, white civil war. It’s between privileged progressives and privileged conservatives. You could say that tribalism is the fruit of privilege. People with more stresses in their lives necessarily pay less attention to politics. . . . I’ve had some differences with Brooks […]

The Golden Rule of Nudge

Nudge unto others as you would have them nudge unto you. Do not recommend to apply incentives to others that you would not want for yourself. Background I was reading this article by William Davies about Britain’s Kafkaesque immigration policies. The background, roughly, is this: Various English politicians promised that the net flow of immigrants […]

Podcast interview on polling (mostly), also some Bayesian stuff

Hugo Bowne-Anderson interviewed me for a DataCamp podcast. Transcript is here.

Rising test scores . . . reported as stagnant test scores

Joseph Delaney points to a post by Kevin Drum pointing to a post by Bob Somerby pointing to a magazine article by Natalie Wexler that reported on the latest NAEP (National Assessment of Educational Progress) test results. In an article entitled, “Why American Students Haven’t Gotten Better at Reading in 20 Years,” Wexler asks, “what’s […]

Strategic choice of where to vote in November

Darcy Kelley sends along a link to this site, Make My Vote Matter, in which you can enter two different addresses where you might vote, and it will tell you in which (if any) of these addresses has elections that are predicted to be close. The site is aimed at students; according to the site, […]

David Weakliem points out that both economic and cultural issues can be more or less “moralized.”

David Weakliem writes: Thomas Edsall has a piece in which he cites a variety of work saying that Democratic and Republican voters are increasingly divided by values. He’s particularly concerned with “authoritarianism,” which is an interesting issue, but one I’ll save for another post. What I want to talk about here is the idea that […]

Bob Erikson on the 2018 Midterms

A couple months ago I wrote about party balancing in the midterm elections and pointed to the work of Joe Bafumi, Bob Erikson, and Chris Wlezien. Erikson recently sent me this note on the upcoming midterm elections: Donald Trump’s tumultuous presidency has sparked far more than the usual interest in the next midterm elections as […]

What do you do when someone says, “The quote is, this is the exact quote”—and then misquotes you?

Ezra Klein, editor of the news/opinion website Vox, reports on a recent debate that sits in the center of the Venn diagram of science, journalism, and politics: Sam Harris, host of the Waking Up podcast, and I [Klein] have been going back and forth over an interview Harris did with The Bell Curve author Charles […]

Statistical Modeling, Causal Inference, and Social Science Regrets Its Decision to Hire Cannibal P-hacker as Writer-at-Large

It is not easy to admit our mistakes, particularly now, given the current media climate and general culture of intolerance on college campuses. Still, we feel that we owe our readers an apology. We should not have hired Cannibal P-hacker, an elegant scientist and thinker who, we have come to believe, after serious consideration, does […]

Echo Chamber Incites Online Mob to Attack Math Profs

The story starts as follows: There’s evidence for greater variability in the distribution of men, compared to women, in various domains. Two math professors, Theodore Hill and Sergei Tabachnikov, wrote an article exploring a mathematical model for the evolution of this difference in variation, and send the article to the Mathematical Intelligencer, a magazine that […]

N=1 survey tells me Cynthia Nixon will lose by a lot (no joke)

Yes, you can learn a lot from N=1, as long as you have some auxiliary information. The other day I was talking with a friend who’s planning to vote for Andrew Cuomo in the primary. What about Cynthia Nixon? My friend wasn’t even considering voting for her. Now, my friend is, I think, in the […]

Narcolepsy Could Be ‘Sleeper Effect’ in Trump and Brexit Campaigns

Kevin Lewis sent along this example of what in social science is called the “ecological fallacy.” Below is a press release that I’ve changed in only a few places: UNDER EMBARGO UNTIL MARCH 8, 2018 AT 10 AM EST Media Contact: Public and Media Relations Manager Society for Personality and Social Psychology press@spsp.org Narcolepsy Could […]

British journalists not running corrections and talking about putting people in the freezer

I happened to be reading an old issue of Private Eye (a friend subscribes and occasionally gives me some old copies) and came across this, discussing various misinformation regarding a recent crime that had been reported by a London tabloid columnist named Rod Liddle (no relation to the famous statistician, I assume): Here is “what […]

How to set up a voting system for a Hall of Fame?

Micah Cohen writes: Our company is establishing a Hall of Fame and I am on a committee to help set it up which involved figuring out the voting system to induct a candidate. We have modeled it somewhat off of the voting for the Baseball Hall of Fame. The details in short: · Up to […]

Discussion of the value of a mathematical model for the dissemination of propaganda

A couple people pointed me to this article, “How to Beat Science and Influence People: Policy Makers and Propaganda in Epistemic Networks,” by James Weatherall, Cailin O’Connor, and Justin Bruner, also featured in this news article. Their paper begins: In their recent book Merchants of Doubt [New York:Bloomsbury 2010], Naomi Oreskes and Erik Conway describe […]

What’s gonna happen in the 2018 midterm elections?

Following up on yesterday’s post on party balancing, here’s a new article from Joe Bafumi, Bob Erikson, and Chris Wlezien giving their predictions for November: We forecast party control of the US House of Representatives after the 2018 midterm election. First, we model the expected national vote relying on available generic Congressional polls and the […]

What is “party balancing” and how does it explain midterm elections?

As is well known, presidential election outcomes are somewhat predictable based on economic performance. Votes for the U.S. Congress, are to a large part determined by party balancing. Right now, the Republicans control the executive branch, both houses of congress, and the judiciary, so it makes sense that voters are going to swing toward the […]

“The most important aspect of a statistical analysis is not what you do with the data, it’s what data you use” (survey adjustment edition)

Dean Eckles pointed me to this recent report by Andrew Mercer, Arnold Lau, and Courtney Kennedy of the Pew Research Center, titled, “For Weighting Online Opt-In Samples, What Matters Most? The right variables make a big difference for accuracy. Complex statistical methods, not so much.” I like most of what they write, but I think […]

The replication crisis and the political process

Jackson Monroe writes: I thought you might be interested in an article [by Dan McLaughlin] in NRO that discusses the replication crisis as part of a broadside against all public health research and social science. It seemed as though the author might be twisting the nature of the replication crisis toward his partisan ends, but […]

If you have a measure, it will be gamed (politics edition).

They sometimes call it Campbell’s Law: New York Governor Andrew Cuomo is not exactly known for drumming up grassroots enthusiasm and small donor contributions, so it was quite a surprise on Monday when his reelection campaign reported that more than half of his campaign contributors this year gave $250 or less. But wait—a closer examination […]
