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 […]

Mister P wins again

Chad Kiewiet De Jonge, Gary Langer, and Sofi Sinozich write: This paper presents state-level estimates of the 2016 presidential election using data from the ABC News/Washington Post tracking poll and multilevel regression with poststratification (MRP). While previous implementations of MRP for election forecasting have relied on data from prior elections to establish poststratification targets for […]

The persistence of bad reporting and the reluctance of people to criticize it

Mark Palko pointed to a bit of puff-piece journalism on the tech entrepreneur Elon Musk that was so extreme that it read as a possible parody, and I wrote, “it could just be as simple as that [author Neil] Strauss decided that a pure puff piece would give him access to write a future Musk […]

He wants to model a proportion given some predictors that sum to 1

Joël Gombin writes: I’m wondering what your take would be on the following problem. I’d like to model a proportion (e.g., the share of the vote for a given party at some territorial level) in function of some compositional data (e.g., the sociodemographic makeup of the voting population), and this, in a multilevel fashion (allowing […]

PNAS forgets basic principles of game theory, thus dooming thousands of Bothans to the fate of Alderaan

Under the subject line, “I needed this information to make a go/no-go decision on my new Death Star,” Kevin Lewis points to this press release from a prestigious journal: Because versions of the below articles were previously posted online, PNAS is publishing the articles without embargo: Potential atmospheres around TRAPPIST-1 planets Simulations of stellar winds […]

About that claim in the NYT that the immigration issue helped Hillary Clinton? The numbers don’t seem to add up.

Today I noticed an op-ed by two political scientists, Howard Lavine and Wendy Rahm, entitled, “What if Trump’s Nativism Actually Hurts Him?”: Contrary to received wisdom, however, the immigration issue did not play to Mr. Trump’s advantage nearly as much as commonly believed. According to our analysis of national survey data from the American National […]

Flaws in stupid horrible algorithm revealed because it made numerical predictions

Kaiser Fung points to this news article by David Jackson and Gary Marx: The Illinois Department of Children and Family Services is ending a high-profile program that used computer data mining to identify children at risk for serious injury or death after the agency’s top official called the technology unreliable. . . . Two Florida […]

Does “status threat” explain the 2016 presidential vote? Diana Mutz replies to criticism.

A couple months ago we reported on an article by sociologist Steve Morgan, criticizing a published paper by political scientist Diana Mutz. Mutz’s original article was called, “Status Threat, Not Economic Hardship, Explains the 2016 Presidential Vote,” and Morgan’s reply is called, “Status Threat, Material Interests, and the 2016 Presidential Vote” (it originally had the […]

Can somebody please untangle this one for us? Are centrists more, or less, supportive of democracy, compared to political extremists?

OK, this is a nice juicy problem for a political science student . . . Act 1: “Centrists Are the Most Hostile to Democracy, Not Extremists” David Adler writes in the New York Times: My research suggests that across Europe and North America, centrists are the least supportive of democracy, the least committed to its […]

Oxycontin, Purdue Pharma, the Sackler family, and the FDA

I just read this horrifying magazine article by Patrick Radden Keefe: The Family That Built an Empire of Pain: The Sackler dynasty’s ruthless marketing of painkillers has generated billions of dollars—and millions of addicts. You really have to read the whole thing, because it’s just one story after another of bad behavior, people getting rich […]
